3/5x-5
I believe this is the expression that is described.
A. volume of the stage in the banquet hall = 22 x 15 x 4 = 1,320 cubic foot.
weight of the stage in the banquet hall:
1 cubic foot weighs 62.4 pounds
1,320 cubic feet will weigh 1,320 x 62.4 = 82,368 pounds.
b. volume of each cylindrical pillar = pi * r^2 * h = pi * (1/2)^2 * 9 = pi * 1/4 * 9 = 7.069 cubic feet
weight of each cylindrical pillar:
1 cubic foot weighs 62.4 pounds
7.069 cubic feet will weigh 7.069 x 62.4 = 441 cubic feet.
Answer:
x=12
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+8+5x−2=90
Step 1: Simplify both sides of the equation.
2x+8+5x−2=90
2x+8+5x+−2=90
(2x+5x)+(8+−2)=90(Combine Like Terms)
7x+6=90
7x+6=90
Step 2: Subtract 6 from both sides.
7x+6−6=90−6
7x=84
Step 3: Divide both sides by 7.
7x7=847
x=12
I think your answer would be 35.36 inches.. i did the math but i’m sorry if i’m wrong!
Answer: A) The equation will be x + 4x + x + 10 = 82 B) Paul's age is 12, Rebecca's age is 48 and Gemma's age is 22.
Step-by-step explanation:
We will represent Paul's age by the equation p= x where p is Paul
We will represent Rebecca's age by the equation r = 4x Where r is Rebecca
We will represent Gemma's age by the equation g = x + 10 where g is also Gemma's age.
We given that the sum of their ages is 82 years so meaning that x + 4x + x + 10 has to equal 82.
A) The equation will be x + 4x + x + 10 = 82
Solve for the x equation to find Paul age because his age is x.
B) (x) + (4x) + (x+10) = 82 combine like terms on the left side
6x + 10 = 82
-10 -10
6x = 72
x= 12
Paul age is 12.
r= 4(12)
r = 48
Rebecca's age is 48.
g= 12 +10
g= 22
Gemma's age is 22.
