step linear equation
-2a+6=18​

Answer:  3. Distributive

Step-by-step explanation:

Distributive property of multiplication over addition is the only property that is require to multiply an expression to the other expression with two or more than two terms.

For example: a (b+c)= a b+ac  , where a,b,c can be any expression.

Given expression:  -5(x-3) = -5x +15 , which illustrates the distributive property of multiplication over addition.

Hence, the correct option is 3. Distributive.

The rest of properties cannot work for multiplication over addition as they are used for one operation.

Answer:

Floor ride up to = 13 floor

Step-by-step explanation:

Given:

Parking garage = 4 floors under ground

Elevator up-to = 17 floor

Find:

Floor ride up to

Computation:

Floor ride up to = Elevator up-to - Parking garage

Floor ride up to = 17 floor - 4 floor

Floor ride up to = 13 floor

Answer:

Step-by-step explanation:

-5y +15 = 3x

divide both sides by 3 to find x

-5y/3 + 5 = x

to find Y you have to isolate it so you add 5y to both sides and subtract 3x from both sides to get

-3x + 15 = 5y

then to find y divide both sides by 5

-3x/5 + 5 = y

Answer:

2x=0

x=0

Step-by-step explanation:

11-3x=5(2-x)+1

We first distribute the 5 to 2 and -x:

11-3x=10-5x+1

Combine like terms (combine all variables and then combine all constants)

-3x+5x=10+1-11

2x=0

x=0

1101₂ + 1110₂ + 1001₂ = 100100₂

1101₂ = 1×2³ + 1×2² + 0×2¹ + 1×2⁰ = 8 + 4 + 0 + 1 = 13₁₀

1110₂ = 1×2³  + 1×2² + 1×2¹ + 0×2⁰ = 8 +  4 + 2 =  14₁₀

1001₂ = 1×2³ + 0×2² + 0×2¹ + 1×2⁰ = 8 + 1 = 9₁₀

13 + 14 + 9 = 36

36₁₀ =

36 : 2 = 18 + r 0

18 : 2 = 9 + r 0

9 : 2 = 4 + r 1

4 : 2 = 2 + r 0

2 : 2 = 1 + r 0

1 : 2 = 0 + r 1  ↑

= 100100₂

Answer:

C

Step-by-step explanation:

the statement (y<1/2x -4) reads "y is LESS than 1/2 x -4."

to fulfil this statement, follow these steps.

1) graph the line 1/2x -4, there will be a yintercept at (0,-4). Also the slope will be increasing (left to right) because 1/2 has no negative sign before it.

2) recognize the inequality sign. In this situation, the solution does NOT INCLUDE THE LINE, rather it includes the area BELOW/LESS THAN the line. If this, < had a line under it, it would mean less than OR equal to.

3) know that if the line is not included, the line will be broken. If the line IS included, which it is not, it would be a solid line.

Answer:

C

Step-by-step explanation:

First, graph the equation:

The y-intercept is -4.

And the slope is 1/2, an upward sloping line.

So, our graph should be either A, B, or C.

D is not correct, so eliminate that.

So, our inequality is:

[tex]y<\frac{1}{2}x-4[/tex]

Note that this inequality is strictly less than. There's no "or equal to" bar. Therefore, our line should be dotted.

Thus, eliminate A and B.

So, C is our answer

Further notes:

The inequality sign means that y is less than the equation. In other words, our shaded region should be below the line.

In C, the shaded area is indeed below the line.

So, C is indeed our answer :)

hope it will help ^_^

Answer:

  A

Step-by-step explanation:

You know that the negative number with the largest magnitude is farthest to the left on the number line.

  3/4 = 9/12

  2/3 = 8/12

Then 3/4 > 2/3, so ...

  -3/4 < -2/3

Answer:

10

Step-by-step explanation:

you would go to desmos graphing calculator and plug in the 2 points and you can see that it goes 8 down and 6 right and when you do Pythagorean theorem you get 64+36 which is 100 and the square root of that is 10 so the distance would be 10 units or simply 10

Answer:

C ) 1/8 * 8 * 8 * 8 * 8 * 8 * 8 * 8

Answer:

Below

Step-by-step explanation:

● x(t) = 2t^2 -20t

A is the average change between t = 1 and t = 3 wich also the velocity.

● A = [x(3)-x(1) ]/(3-1)

● A = [ x(3) - x(1)] / 2

● x(3) = 2×3^2 - 20 ×3 = 18-60= -42

● x(1) = 2×1^2 -20×1 = 2-20 = -18

● A = (-42-(-18))/2

● A = (-42+18)/2

● A = -24 /2

● A = -12

A is negative so the car must be going backwards

Answer:

Step-by-step explanation:

3 of the 6 sides that exist on a dice have odd numbers.

Answer:

1/2 probability of getting an odd number

Step-by-step explanation:

Dice have the given outcomes of getting a 1, 2, 3, 4, 5, or 6. Considering that the desired outcomes are only 3 out of 6 of those given outcomes, that leaves us with a 3/6 or 1/2 chance of getting an odd number.

Answer:

4x + 16

Step-by-step explanation:

The area of the shaded region = area of the outer rectangle - area of the inner rectangle

Area of rectangle = l*w

Area of outer rectangle, where length (l) = (x + 5), and width (w) = (x + 4):

Area = (x + 5)(x + 4)

Expand

x(x + 4) +5(x + 4)

x² + 4x + 5x + 20

area of outer rectangle = x² + 9x + 20

Area of inner rectangle, where length (l) = (x + 4), and width (w) = (x + 1):

Area = (x + 4)(x + 1)

Expand

x(x + 1) +4(x + 1)

x² + x + 4x + 4

Area of inner rectangle = x² + 5x + 4

Area of shaded region = (x² + 9x + 20) - (x² + 5x + 4)

x² + 9x + 20 - x² - 5x - 4

Collect like terms together

x² - x² + 9x - 5x + 20 - 4

4x + 16

Area of the shaded region = 4x + 16

Answer:

The rate of the plane is 753 km/h while the rate of the wind is 75km/h

Step-by-step explanation:

Here in this question, we are interested in calculating the rate of the plane in still air and the rate of the wind.

Since we do not know these rates, we shall be representing both using variables.

Let’s represent the rate of the plane in still air by x kmph while the rate of the wind be represented by y kmph

Now, for us to calculate the speed of the plane while it travels against the wind, that would be the speed of the plane in still air minus the speed of the wind.

Mathematically, that would be (x-y) kmph

Now the speed of the plane while it travels with the wind would be its speed in still air plus the speed of the wind.

Mathematically, that would be;

(x + y) kmph

From the question;

The plane journeyed 5424 km against the speed in 8 hours, this means that its speed will be 5424/8 = 678 kmph

Thus, that means;

x -y = 678 •••••••(i)

Now, traveling with the wind , its speed will be ;

6624/8 = 828 kmph

Thus;

x + y = 828 kmph •••••••(ii)

So we have two equations to solve simultaneously;

Let’s add both together;

x -y + x + y = 828+ 678

2x = 1,506

x = 1506/2

x = 753 kmph

From ii

x + y = 828

y = 828 - x

y = 828 - 753

y = 75 kmph

Answer:

d. AB

e. A/B

Step-by-step explanation:

From the concept of homogeneity of dimension. The principle is that if two quantities occurs in the same direction, addition and subtraction of those two variable tends to occur but if two quantities occur in different direction, then we can only have either the division and multiplication of those quantities.

From the given information;

Suppose two quantities, A and B, have different dimensions.

The arithmetic operations  that could be physically meaningful are :

d. AB

e. A/B
