If B is between A and C, AB = x, BC = 2x + 2, and AC = 14, find the value of x. Then find AB and BC.
This should serve as a guide
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]AB = x[/tex]
[tex]BC = 2x + 2[/tex]
[tex]AC =14[/tex]
Required
Determine x, AB and BC.
Since B is between A and C;
[tex]AB + BC = AC[/tex]
Substitute x for AB; 2x + 2 for BC and 14 for AC
[tex]x + 2x + 2 = 14[/tex]
[tex]3x + 2 = 14[/tex]
Collect Like Terms
[tex]3x = 14 - 2[/tex]
[tex]3x = 12[/tex]'
[tex]x = \frac{12}{3}[/tex]
[tex]x = 4[/tex]
Substitute 4 for x in
[tex]AB = x[/tex]
[tex]BC = 2x + 2[/tex]
[tex]AB = 4[/tex]
[tex]BC = 2(4) + 2[/tex]
[tex]BC = 8 + 2[/tex]
[tex]BC = 10[/tex]

Given that M the midpoint of VW, what is the length of line segment VM?
4x-1 3x + 3
Answer:
VW = 30
Step-by-step explanation:
As M is the mid point of VW , VM = MW...........eqn 1
We know that VM = 4x - 1 & MW = 3x + 3
Equating VM & MW in eqn 1,
4x - 1 = 3x + 3
=> 4x - 3x = 3 + 1
=> x = 4
Substituting the value of x in VM & MW,
VM = 4×4 - 1 = 15
MW = 3×4 + 3 = 15
VW = VM + MW = 30

(5x-25)+(3x+9)=180 please answer right now
Answer:
[tex]x=24.5\\[/tex]
Step-by-step explanation:
So we have the equation:
[tex](5x-25)+(3x+9)+180[/tex]
Combine like terms:
[tex](5x+3x)+(-25+9)=180[/tex]
Add:
[tex]8x-16=180[/tex]
Add 16 to both sides:
[tex]8x=196[/tex]
Divide both sides by 8:
[tex]x=24.5\\[/tex]
So, our answer is 24.5 :)
Solve w= 1/2 x^2y for y
Answer:
y = 2w / x^2.
Step-by-step explanation:
w = 1/2x^2 y
We divide both sides by 1/2 x^2
y = w / (1/2 x^2)
y = 2w / x^2.
Wilma has 21 coins in her pocket made up of dimes and quarters. If the total value of the coins is $3.45, how many of each coin does she have?
Answer:
x = 12
y = 9
12 coins of dimes
9 coins of quartes
Step-by-step explanation:
x ---> coins of dimes
y ---> coins of quartes
x + y = 21
0.1x + 0.25y = 3.45 * 100
x + y = 21 L1
10x + 25y = 345 L2
x = 21 - y
Reemplace in L2
10(21 - y) + 25y = 345
210 - 10y + 25y = 345
15y = 345 - 210
15y = 135
y = 9
x = 21 - y
x = 21 - 9
x = 12

What is (-3/4)x(7/8)
I’ve noticed here are around 4 ways to solve a Quadratic Equation. Factoring, Completing the square, The quadratic Formula, and graphing. With some equations, it seems that all 4 can be used for solving. But for a lot of equations, sometimes factoring doesn’t work, and you’ll have to use the Quadratic formula. Or maybe the Quadratic Formula is too slow and you need to factor instead etc. Is there an easy or quick way to tell, just by looking at a quadratic equation, which method is best for solving?
Answer:
See explanation
Step-by-step explanation:
Usually, I just find the quadratic formula the easiest to go, but here are some tips to tell if which you should use.
1. First see if you can get integer values for the roots to multiply to c and add to b.
This is the easiest way to solve a quadratic equation, and I always check for whether I can easily find the roots by multiply two numbers for c and adding them for b.
For instance, the Quadratic [tex]x^2 + 5x + 6[/tex]
I can easily see that 2 and 3 are the roots here - as [tex]2\cdot3=6[/tex] and [tex]2+3=5[/tex]. If you can do this and receive integer values, then great! I'd definitely stick with this.
2. See if you can complete the square
If you have a quadratic which is a perfect square, you'll be able to tell if c is a perfect square, and b is twice that number. This will be easiest. Any quadratic equation can be solved by completing the square, but I personally stick to this method only if I can tell it's a perfect square quadratic.
3. Stick to the Quadratic Formula
If all else fails, go with the Quadratic formula. It's not that hard and it gets the job done. I would highly discourage going with graphing, as it takes too much time and it's quite a hassle unless you have a graphing calculator.
I really hope this helped!
Answer:
In my preferred order, ...
use a graphing calculatorfactoruse the quadratic formulaStep-by-step explanation:
My personal favorite is to use a graphing calculator. If it shows the zeros are whole numbers, your solution is at hand. If it shows the zeros are recognizable decimal fractions*, the solution is also at hand. If it shows the zeros are unrecognizable as fractions, they are likely irrational. Then the vertex of the graph gets you most of the way to an exact solution.
If the quadratic's coefficients are not integers, then the quadratic formula is least likely to give difficulty.
Example
The attached is a graph of the quadratic ...
y = 2x^2 -3x -4
We can see from the x-intercepts that the roots are irrational (none are fractions with a denominator that is a factor of 2). The vertex of the graph is (3/4, -5 1/8), so the vertex form of the equation for this graph is ...
y = 2(x -3/4)^2 -(5 1/8)
Solving this for y=0, we find ...
0 = 2(x -3/4)^2 -(5 1/8)
5 1/8 = 2(x -3/4)^2 . . . . . .add the constant (vertex y-value)
(5 1/8)/2 = (x -3/4)^2 . . . . divide by 2 (the leading coefficient)
2 9/16 = (x -3/4)^2
x = 3/4 ± √(41/16) . . . . . . . add the horizontal offset (vertex x-value)
x = (3 ± √41)/4 . . . . . . . . . . simplify
If you see what we've done here, you can write down the answer from the vertex and the leading coefficient:
x = (3/4) ± √((5 1/8)/2) . . . . . vertex (3/4, 5 1/8), leading coefficient 2
__
With a little practice, factoring can be a relatively simple way to find the solution. As a preliminary step, the equation should be divided by any common factor of the coefficients, so they are all relatively prime. It helps immensely to know your times tables thoroughly. I like this method, because it can get a solution with fewer steps than using the quadratic formula.
The product of two binomials is ...
(ax +b)(cx +d) = acx^2 +(ad+bc)x +bd
The product of the leading coefficient (ac) and the constant (bd) is abcd. It has factors of ad and bc, whose sum is the coefficient of the linear term. So, if you can factor the product of the leading and trailing coefficients and find a sum of factors that is the middle coefficient, you're home free. Sometimes the factors jump out at you, and sometimes you need to list a bunch of them before you see what you need.
In our example, we would be looking for factors of 2(-4) = -8 that have a sum of -3.
-8 = (-8)(1) = -4(2) = (-2)(4) = (-1)(8)
These pairs have sums of -7, -2, 2, 7. None of the sums is -3, so factoring by integers is not possible. You can see that it is unnecessary to list the pairs with positive sums in this case.
Once you have the values ad and bc, you can see that 'a' is the greatest common divisor of ac and ad. Then ad/a = d, and ac/a = c. Now you know 3 of the 4 numbers in the binomial factors.

* The Rational Root Theorem can tell you what reasonable fractions might be for your quadratic. You should be familiar with the decimal equivalents of fractions with small integer denominators.
What would be the fourth and fifth figures? How many dots will be in the 100th figure?
Answer:
4th=8 dots
5th=10 dots
100th=200 dots
Step-by-step explanation:
Since you’re adding two dots each time, it will always bed double the figure number.
4th=8 dots
5th=10 dots
100th=200 dots
Answer:
The fourth figure is 8 Dots
The fifth figure is 10 Dots
The hundredth figure will be 200 Dots
Step-by-step explanation:
The figure dots increase by two so we multiply the dot number by the amount of increase
which means
The Fourth figure have 4 dots so 4 × 2=8
The Fifth figure have 5 dots so 5 × 2 =10
The hundredth figure have 100 dots so 100 × 2 =200

James read that bears can weight up to 125 kg. He wants to convert this to pounds so he can understand how heavy that really is. Convert the bears weight to pounds. (1kg = 2.205 lbs)
Answer:
275.63 pounds
Step-by-step explanation:
To convert it to pounds, multiply the weight in kg by 2.205
125(2.205)
= 275.63 pounds
Answer:
125 kg = 275.578 lbs
Step-by-step explanation:
1 Kilogram (kg) is equal to 2.2046226218 pounds (lbs). To convert kg to pounds, multiply the kg value by 2.2046226218. For example, to convert 4 kilograms to pounds, multiply 4 by 2.2046226218, that makes 4 kg is 8.81849049 lbs.

Stuck on this 6/9 times 3
Answer:
2
Step-by-step explanation:
6/9 * 3
First you can either simplify this to make it easier or directly multiply. Simplify it by dividing 3 on the 9.
6/3=2
Or you can multiply and it would be 18/9, because 6*3=18.
18/9=2
