Answer:
24 adults
Step-by-step explanation:
The equation to represent the scenario is
4x + 7x = 66
Combine like terms
11x = 66
Isolate x
x = 6
To find the amount of adults attending the carnival, substitute 6 with x.
6*4 = 24 adults
7*4 = 42 children
24 + 42 = 66 people in total

Answer:
r = 24
Step-by-step explanation:
3(r+2)+5(2−r)=−32
Step 1: Simplify both sides of the equation.
3(r+2)+5(2−r)=−32
(3)(r)+(3)(2)+(5)(2)+(5)(−r)=−32(Distribute)
3r+6+10+−5r=−32
(3r+−5r)+(6+10)=−32(Combine Like Terms)
−2r+16=−32
−2r+16=−32
Step 2: Subtract 16 from both sides.
−2r+16−16=−32−16
−2r=−48
Step 3: Divide both sides by -2.
−2r/-2 = -48/-2
r = 24
Answer:
Step-by-step explanation:
V = (4/3)(3.14)(3^3)
V = 4/3 * 27 * 3.14
V = 36 * 3.14
V = 113.04
