Answer:

x=4

Step-by-step explanation:

3(9-8x-4x)+8(3x+4)=11

Subtract 4 x from − 8 x

3 ( 9 − 12 x ) + 8 ( 3 x + 4 ) = 11

Distribute

27 − 36 x + 24 x + 32 = 11

Simplify

− 12 x + 59 = 11

Subtract 59 to both sides

− 12 x = − 48

Divide by -12

x=4

What number when multiplied by 5 is one third of the sum of 64 and 56?

Nookie1986 [14]

Answer:

Step-by-step explanation:

Create an expression to model the situation. One can do this by simply rewriting the written expression in terms of numbers and variables. Use the variable (x) to represent the unknown value.

$5(x)=\frac{1}{3}(64+56)$

Simplify this expression,

$5(x)=\frac{1}{3}(64+56)\\5x=\frac{1}{3}(120)\\5x=40\\$

Use inverse operations to solve for (x),

$5x=40\\x=8$
