Let's say that s=spoons and f=forks.
According to this, we can say that:
{4s+3f=15
{4s+f=13
This is a system.
We can then use elimination to solve and isolate the variable:
(4s-3f=15)
- (4s+f=13)
We can then subtract and conclude that:
-4f=2
-f=1/2
f=-1/2
4 units up means 4 is added to the y-coordinate
(-5, -3 + 4) and (0, 2 + 4)
= (-5, 1) and (0, 6)
Answer: B
To solve this we must set up a proportion.
For each pie we need 2 pounds because you divide 4 by 2.
So we do 5 times 2 which gives us 10 pounds per 5 pies
Your answer is
You need 10 pounds of apples for 5 pies.
4 feet
Step-by-step explanation:
there's 12 inches in a foot. so 48÷12= 4 feet
Let Kylie's container (which is 400ml) be 100%. She drank 35%. Proportion:
400ml - 100%
x ml - 35%
So Kylie drank:
x=(400*35)/100=140 ml of water
Whole Eugenia's container (350ml) is also 100% and she drank 45%.
350ml - 100%
xml - 45%
Eugenia drank:
x=(350*45)/100=157,5ml of water
Thus, Eugenia drank (157,5-140)=17,5 ml more than Kylie
