7 0

30x + 20 = 50

20 + -20 + 30x = 50 + -20

0 + 30x = 50 + -20 30x = 50 + -20
50 + -20 = 30 30x = 30

x = 1

30x - 20 = 50
use inverse operations to isolate x

30x - 20 = 50
+ 20 +20

30x = 70
(30x = 70) /30

x= 7/3 (this is the simplified term)

6. A prism has bases that are equilateral triangles with sides lengths of 10 inches and a length of 30 inches.

eimsori [14]

Answer:

The volume of the prism is $1,299\ in^{3}$

Step-by-step explanation:

we know that

The volume of the prism is equal to

$V=BL$

where

B is the area of the triangular base

L is the length of the prism

we have

$L=30\ in$

Find the area of the base B

The area of a equilateral triangle is equal to

$B=\frac{1}{2}(10)^{2} sin(60\°)$

$B=25\sqrt{3}\ in^{2}$

substitute

$V=(25\sqrt{3})(30)=1,299\ in^{3}$
