What value of x makes the equation 3(x – 6) – 8x = –2 + 5(2x + 1) true? Explain your answer

GaryK [48]

Answer:

x = -7/5

Step-by-step explanation:

3( x - 6 ) - 8x = -2 + 5(2x + 1)

3x - 18 - 8x = -2 + 10x + 5

-5x - 18 = 3 + 10x

-5x - 10x = 3 + 18

-15x = 21

x = $-\frac{7}{5}$

How to find volume of 7 and 8? (20 pts)

Airida [17]

Answer:

7

Step-by-step explanation:

7.base of triangle=√(32.5²-28²)

=√4.5(32.5+28)

=√4.5(60.5)

=√272.25

=16.5

area of triangle=1/2 ×16.5×28

=231

volume=231×31=7161 km³

8.

39.4-25=14.4

width=√(30.6²-14.4²)

=√16.2(30.6+14.4)

=√16.2(45)

=√729

=27

volume=(25+39.4)/2 ×27×35

=(64.4)/2×27×35

=32.2×27×35

=30429 cm³
