Answer:

When x = 12, y = 4, and z = 2, 8x + 2yz = 112.

Step-by-step explanation:

8x + 2yz

Substitute variables given:

x = 12

y = 4

z = 2

8(12) + 2(4)(2)

Multiply 8 and 12.

96 + 2(4)(2)

Multiply 2 and 4.

96 + 8(2)

Multiply 8 and 2.

96 + 16

Add 96 and 16.

112.

Answer:

[tex] = > 8(12) + 2(4)(2)[/tex]

[tex] = > 96 + 8(2)[/tex]

[tex] = > 96 + 16[/tex]

[tex] = > 112[/tex]

Answer:

4, 2, 8

Step-by-step explanation:

We want to write an function that relates the number of blocks south of school that she is to the number of minutes that she has been walking.

The function is: y = (1 block/minute)*x + 8 blocks

A general linear function is:

y = a*x + b

where a is the slope and b is the y-intercept.

First, we do know that she lives 8 blocks south of her school, so the y-intercept of the linear function will be 8 blocks (the point where she starts).

Now we know that her friend lives farther south, so she moves south, at a velocity of 1 block per minute.

Then the linear function is:

y = (1 block/minute)*x + 8 blocks

Answer:

z+y/5=x or z/5 + y/5 = x

Step-by-step explanation:

z=5x-y

add y to both sides

z+y=5x

divide both sides by 5

z+y/5=x or z/5 + y/5 = x

Answer:

y+3 = -4(x-2)

Step-by-step explanation:

We can use point slope form since we are given a point on the line and a slope,

Point slope form is

(y-y1) = m(x-x1) where m is the slope and (x1,y1) is a point on the line

(y- -3) = -4(x-2)

y+3 = -4(x-2)

Answer: 21

Step-by-step explanation:

To find the missing number you set the two equations as a proportion:

[tex]\frac{7}{9} = \frac{x}{27}[/tex]

To solve for x we cross multiply:

27 × 7 = 189

9 × x = 9x

Set up an equation:

9x = 189

Divide both sides by 9:

x = 21

Answer:

687

Step-by-step explanation:

I know this is a joke but I'll help you out anyway.

7 - 18 = (-11)

(-11) + 20 = 9

9 + 0 = 9

9 - 322 = -313

-313 + 1000 = 687

Therefore, your answer is 687.

Based on the distance they covered in the time they did, we can infer that Zahara's dad was driving at 53 miles per hour.

To find the speed, the following formula is used:

= Distance / Time

They travelled 159 miles in 3 hours.

Distance = 159 miles

Time = 3 hours

The speed must be:

= 159/3

= 53 miles per hour

In conclusion, he was going at 53 miles per hour.
