Answer:

C and E

Step-by-step explanation:

The variable "y" has to be by itself so here is the breakdown to that:

-3x + 6y + 5 = - 7

6y + 6 = 3x - 7

6y = 3x - 7 - 6

6y = 3x - 12

6y/6 = 3x/6 - 12/6

y = 1/2 x - 2

Then you would graph -2 --> (0, -2) and use 1/2 to navigate upwards to get your answers.

Answer:

A, 152 cm.

Step-by-step explanation:

A rectangular pyramid has a volume equation of

V = (lwh)/3.

Therefore, when we plug the values in:

[(7)(5)(13)]/3 = V

V = 455/3

V = 151.666667

V is approximately equal to 152 cm^3.

I hope this helped! :)

For each pair of similar figures, find the ratio of the area of the first figure to the area of the second.

Hitman42 [59]

answer:

$\frac{4}{9}$

explanation:

the area of the larger square is 36 (6*6), and the area of the smaller square is 16 (4*4). to find the ratio of the area, simply just put 16 over 36 and simplify.

$\frac{16}{36} = \frac{4}{9}$

What value of x is in the solution set of 2x – 3 > 11 – 5x?

pochemuha

Given:

2x -3 > 11 -5x

Simplify both sides:

2x - 3 > -5x + 11

Add 5x to both sides:

2x - 3 +5x > -5x + 11 +5

7x - 3 > 11

Add 3 to both sides:

7x - 3 +3 > 11 + 3

7x > 14

Divided 7 to both sides:

$\frac{7x}{7}$ > $\frac{14}{7}$

x > 2
