PLEASE ANSWER ASAP!!! Solve for X. 15=7x+3-5x X=_(simplify your answer)
Answer:
X=6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
15=7x+3−5x
15=7x+3+−5x
15=(7x+−5x)+(3)(Combine Like Terms)
15=2x+3
15=2x+3
Step 2: Flip the equation.
2x+3=15
Step 3: Subtract 3 from both sides.
2x+3−3=15−3
2x=12
Step 4: Divide both sides by 2.
2x2=122
x=6

-16=-1+3x
first you add 1 to both sides making it: -15=3x
then you divide both sides by 3
you get -5=x
Answer:
x = -5
Step-by-step explanation:
-1 + 3x = -16
-1 +3x +1 = =16 +1
3x = -15
x = -5
What is the sum of the first 150 odd positive integers?
Show work please!!!
Answer:
11325.
Step-by-step explanation:
Step 1: address the formula, input parameters & values.
Input parameters & values:
The number series 1, 2, 3, 4, . . . . , 149, 150.
The first term a = 1
The common difference d = 1
Total number of terms n = 150
Step 2: apply the input parameter values in the formula
Sum = n/2 x (a + Tn)
= 150/2 x (1 + 150)
= 22650/2
1 + 2 + 3 + 4 + . . . . + 149 + 150 = 11325
Therefore, 11325 is the sum of positive integers up to 150.
The sum of the first 150 odd positive integers is 11325.
The number series 1, 2, 3, 4, . . . . , 149, 150.
The first term a = 1
The common difference d = 1
Total number of terms n = 150
Sum = n/2 x (a + Tn)
= 150/2 x (1 + 150)
= 22650/2
1 + 2 + 3 + 4 + . . . . + 149 + 150 = 11325

5-9(8 - 2x) < 2x - 115 solve for x
Answer:
x < -3
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
5 - 9(8 - 2x) < 2x - 115
Step 2: Distribute parenthesis
5 - 72 + 18x < 2x - 115
Step 3: Combine like terms
-67 + 18x < 2x - 115
Step 4: Add 67 on both sides
18x < 2x - 48
Step 5: Subtract 2x on both sides
16x < -48
Step 6: Divide both sides by 16
x < -3
And we have our answer!
Answer:
x<-3
Step-by-step explanation:
5−9(8−2x)<2x−115
Use the distributive property to multiply −9 by 8−2x.
5−72+18x<2x−115
Subtract 72 from 5 to get −67.
−67+18x<2x−115
Subtract 2x from both sides.
−67+18x−2x<−115
Combine 18x and −2x to get 16x.
−67+16x<−115
Add 67 to both sides.
16x<−115+67
Add −115 and 67 to get −48.
16x<−48
Divide both sides by 16. Since 16 is >0, the inequality direction remains the same.
x<-48/16
Divide −48 by 16
x<−3

x/11 = 13/11 please help
Answer:
[tex]x=13[/tex]
Step-by-step explanation:
So we have:
[tex]\frac{x}{11}=\frac{13}{11}[/tex]
To solve for x, multiply both sides by 11.
[tex](11)\frac{x}{11}=(11)\frac{13}{11}[/tex]
Both the left and the right cancel. Thus:
[tex]x=13[/tex]
Our answer is 13 :)
Answer:
Hey there!
x=13
The denominator is the same for both sides, so to make the equation equal, x has to be 13.
Hope this helps :)
What's 5(m−2)−10=6+2(1−m)
Answer: m=4
Step-by-step explanation:
5(m-2) - 10 = 6 + 2(1 - m) Apply the distributive property on both sides
5m -10 -10 = 6 + 2-2m Now combine like terms on both sides
5m -20 = 8- 2m Now add 2m to both sides
+2m +2m
7m - 20= 8 Add 20 to both sides
+20 +20
7m = 28 Divide both sides by 7
m = 4

Work Shown:
g(x) = x^2-2
g(-2) = (-2)^2-2
g(-2) = 2
Saying (-2, g(-2)) is the same as saying (-2, 2)
---------------
g(x) = x^2-2
g(1) = 1^2 - 2
g(1) = -1
Saying (1, g(1)) is the same as saying (1, -1)
---------------
Let's find the slope of the line through (-2,2) and (1,-1)
m = (y2 - y1)/(x2 - x1)
m = (-1-2)/(1-(-2))
m = (-1-2)/(1+2)
m = -3/3
m = -1
Now turn to point slope form to find the equation
y - y1 = m(x - x1)
y - 2 = -1(x - (-2))
y - 2 = -(x + 2)
y - 2 = -x - 2
y-2+2 = -x-2+2 ... add 2 to both sides
y = -x
You could use the other point (1,-1) and you'd get the same answer. The slope m = -1 is the same each time.

Answer:
[tex] \boxed{ \bold{ \boxed{ \sf{15 \: cookies}}}}[/tex]

Total cookies = 150
percentage of cookies that she ate = 10 %
To find : Number of cookies that she ate
[tex] \sf{10\% \: of \: 150}[/tex]
To convert percent into fraction, divide it by 100 and remove the % symbol.

B. If you have trouble with sums, your calculator can help.
-22 + (-44) = -22 -44 = -66

C. -36/x = -9 can be solved by multiplying by x and dividing by -9:
-36 = -9x
-36/-9 = x = 4
Since the product of the divisor and quotient is the dividend, dividing the dividend by either gives the other. Here, your dividend is -36 and your quotient is -9. To find the divisor, you can divide -36 by -9, as we did.

D. The absolute value function changes the sign of negative numbers to positive:
|-998| = 998

A line passes through the points (2,3) and (6,y) with a slope of 2. What is the value of y?
Answer:
5
Step-by-step explanation:
The slope of a line is always rise over run.
We need to make the rise over run equivalent to 2 to find the value of y.
Looking at the x-coordinates, 2 and 6, we can see there is an increase in 4.
Now we ask: What number, times 2, will equal 4?
That is 2.
So we have to make the increase in the y coordinates 2.
If we have the original point 3, an increase in 2 is 5.
So y is 5.
Hope this helped!
Answer:
11 = y
Step-by-step explanation:
Using the slope formula
m = (y2-y1)/(x2-x1)
2 = (y-3)/(6-2)
2 = (y-3)/4
Multiply each side by 4
2*4 = y-3
8 = y-3
Add 3 to each side
8+3 = y-3+3
11 = y

When driving in England, a U.S. tourist puts gasoline in his car and pays 1.35 European pounds per liter (pounds per liter). The price of gasoline in his U.S. hometown is $3.39 per gallon. Suppose the exchange rate is 0.705 pounds for $1.50. Is gasoline more expensive in England or in the U.S.?
Answer: England
Step-by-step explanation:
England: 1.35 euro/liter
[tex]\text{U.S:}\quad \dfrac{\$3.39}{gallon}\times \dfrac{0.705\ euro}{\$1.50}\times \dfrac{1\ gallon}{3.785\ liter}=\dfrac{0.42\ euro}{liter}[/tex]
1.35 > 0.42
England > US
Elizabeth wrote 3.3 - 0.21= 1.2 Is her answer reasonable? Explain why or why not. Choose the correct answer below and fill in the answer box to complete your choice. A. The estimate would be 0-0= nothing, so her answer is reasonable. B. The estimate would be 4-0= nothing, so her answer is not reasonable. C. The estimate would be 3-0= nothing, so her answer is not reasonable. D. The estimate would be 3-0= nothing, so her answer is reasonable.
Answer:
The estimate would be 3-0= nothing, so her answer is not reasonable.Step-by-step explanation:
Given the expression written by Elizabeth as 3.3 - 0.21= 1.2, to check if Elizabeth expression is reasonable or not, we need to check if her answer is close to or equal to the answer of the diiferebce between 3.3 - 0.21.
Converting 3.3 and 0.21 to fraction
3.3 = 33/10
0.21 = 21/100
Taking the difference of both fractions
[tex]= \dfrac{33}{10} -\dfrac{21}{100} \\\\= \dfrac{330-21}{100} \\\\= \dfrac{309}{100} \\\\= 3.09\\[/tex]
Hence 3.3 - 0.21 = 3.09 ≈ 3.0 (to nearest whole number). Comparing Elizabeth answer which is 1.2 to the answer f=gotten, it can be seen that her answer is far from the right answer with a difference of about 1.8 (3.0-1.2). This large difference makes Elizabeth answer unreasonable.
D.
The estimate would be 30
3, so her answer is not reasonable

What is the solution to this system of equations?
x + 3y - z = 6
4x - 2y + 2z= -10
6x + z= -12
(an explanation would be great because i barely understand how to do this)
Answer:
[tex]x=-3, y=5, z=6[/tex]
Step-by-step explanation:
1. Divide by 2 both sides in the second equation:
[tex]4x - 2y + 2z= -10[/tex] [tex]2x - y + z= -5[/tex]2. From the third equation find z in terms of x:
[tex]6x + z= -12[/tex] [tex]z= -6x-12[/tex]3. Add up the first and new second equations and find y in terms of x:
[tex](x+2x)+(3y-y)+(-z+z)=6+(-5)[/tex] [tex]3x+2y=1[/tex] [tex]2y=1-3x[/tex] [tex]y=0.5-1.5x[/tex]4. Put new alternatives instead of y and z in the first equation:
[tex]x+3(0.5-1.5x)-(-6x-12)=6[/tex] [tex]x+1.5-4.5x+6x+12=6[/tex] [tex]2.5x=-7.5[/tex] [tex]x=-3[/tex]5. Now we can easily find other two unknowns by using their equations by means of x:
[tex]y=0.5-1.5\times(-3)[/tex] [tex]y=0.5+4.5[/tex] [tex]y=5[/tex][tex]z=-6\times(-3)-12[/tex] [tex]z=18-12[/tex] [tex]z=6[/tex]Answer:
Step-by-step explanation:
2x + 6y - 2z = 12
12x - 6y + 6z = -30
14x + 4z = -18
6x + z = -12
14x + 4z = -18
-24x - 4z = 48
-10x = 30
x = -3
6(-3) + z = -12
-18 + z = -12
z = 6
-3 + 3y - 6 = 6
-9 + 3y = 6
3y = 15
y = 5
x = -3, y = 5, z = 6
