Answer:
4/3
Step-by-step explanation:
6n - 4 = 3n + 8
6n - 3n = 8 + 4
3n = 4
n = 4/3
Goodluck with your schoolwork/homework.

Answer:
A≈50.27in²
Step-by-step explanation:
Ok so there's 5 sides
let's find interior angle sum
formula is S=180(n-2)
n in this case is 5 since there are 5 sides
S=180(5-2)
S=180(3)
S=540
so now add the 5 angle lengths up to 540
5x+2+10x-3+7x-11+13x-31+8x-19=540
43x+-62=540
+62 +62
43x=602
divide both sides by 43
x=14!!!!!
Answer:
Step-by-step explanation:
Given:
Number of feathers = 
Number of caps = 
Number of feathers in each cap = 3
Now, solving by setting up a proportion.
1 cap has 3 feathers. 'c' caps has 'f' feathers.
This gives,
Solving by cross multiplication, we get:
Therefore, the equation representing the number of feathers 'f' Erica needs to make 'c' caps is given as:
Answer:
Step-by-step explanation:
Let b represent the number of cups of butter needed.
Let s represent the number of cups of sugar needed.
Let o represent the number of cups of oat needed.
Let f represent the number of cups of flour needed.
The recipe calls for two times as many cups of sugar as butter. It means that
s = 2b
Two times as many cups of oats as sugar. It means that
o = 2s
Two times as many cups of flour as oats. It means that
f = 2o
If Duane puts in one cup of butter, it means that b = 1
Therefore,
s = 2 × 1 = 2 cups
o = 2s = 2 × 2 = 4 cups
f = 2o = 2 × 4 = 8 cups
Therefore, he needs to add 8 cups of flour
