I think A^3:B^
Explanation:
It is 3 dimensional, so the surface area would be 3x bigger, so A^3:B^
Answer:
y=-3
x=0
Step-by-step explanation:
we are given that (x=y+3).Let's substitute this expression into the first equation and solve for y as follows:
6x-5y=15
6 times (y+3)-5y=15
6y+18−5y=15
y=-3
x=y+3
x=-3+3
x=0
Answer:
3/10
Step-by-step explanation:
Take the number of pizzas and divide by the number of people
3 pizzas / 10 people
Each person got 3/10 of a pizza
Answer: The correct answer is 3.
Step-by-step explanation:
You need to write an equation to solve this problem, using x as the number of personal training sessions.
The equation to solve this problem is
35 + 25 x = 65 + 15x
First, subtract 35 from both sides:
25x = 30 + 15x
Subtract 15x from both sides:
10x = 30
The last step is to divide both sides by 10:
x = 3
You can then double check your work to make sure that the answer is correct:
35 + (25 x 3) = 110
65 + (15 x 3) = 110
