Answer:
Step-by-step explanation:
We have a 4-sided triangular pyramid
, where
80 goes into 142 once, so one is our whole number. there are still 62 / 80 left, so we reduce this fraction. The answer is
1
Answer:
Mason is incorrect.
Step-by-step explanation:
Equivalent ratios are formed when the same number is MULTIPLIED to each number in the ratior, not when the same number is added. So for example, a ratio equivalent to 2:3 would be 4:6, because 2*2=4 and 3*2=6. You multiply to create equivalent ratios, not add.
(That would be your explanation)
let's make p stand for popcorn and d for drinks. Using those variables, we can create our equations:
2p + 3d = 18.25
4p + 2d = 27.50
From this, we can use substitution or elimination to solve:
For substitution, in the second equations, we could factor out a 2, divide both sides by 2, and then move the left over 2p to the other side to isolate d to put into the first equation.
For elimination, we can multiply the first equation by -2 so that we can remove the 4p and focus on solving for d.
I'll be using elimination in this case:
-2(2p + 3d = 18.25) --> -4p - 6d = -36.50
-4p - 6d = -36.50
4p + 2d = 27.50
-4d = -9.00
d = 2.25
4p + 2 * 2.25 = 27.50
4p + 4.50 = 27.50
4p = 23.00
p = 5.75
Now let's check our answer:
2 * 5.75 + 3 * 2.25 = 18.25
11.50 + 6.75 = 18.25
18.25 = 18.25
So drinks cost $2.25 and popcorn $5.75
Answer:
4(20+3)
Step-by-step explanation:
you can just add 20+3 to make the (23) part of the equation it's very simple dont make it complicated luv
