Answer: x=-10
Step-by-step explanation:
Let's solve your equation step-by-step.
6.2x+8=3(1.4x−4)
Step 1: Simplify both sides of the equation.
6.2x+8=3(1.4x−4)
6.2x+8=(3)(1.4x)+(3)(−4)(Distribute)
6.2x+8=4.2x+−12
6.2x+8=4.2x−12
Step 2: Subtract 4.2x from both sides.
6.2x+8−4.2x=4.2x−12−4.2x
2x+8=−12
Step 3: Subtract 8 from both sides.
2x+8−8=−12−8
2x=−20
Step 4: Divide both sides by 2.
2x2=−202
<span>Use the formula below to find the volume of the beach ball.
Remember that the radius is one-half of the diameter.
V=3/4 pi r^3
=4/3(3.14)(9 in)^3
=3,052.08
Therefore, the beach ball has a volume of 3,052.08 cubic inches when it is completely full.
