Answer:
<h2>There are 664 diet soda</h2>
Step-by-step explanation:
Step one:
given data
total soda= 913
we are told that the ratio of diet sodas to regular sodas is 8:3
this means that for every 8 diet soda there is 3 regular soda
the total ratio is 8+3=11
Step two:
we are going to use part to all principle
let the diet soda be x
8/11=x/913
cross multiply
11x=913*8
divide both sides by 11
x=913*8/11
x=7304/11
x=664
There are 664 diet soda
Do the variable first (x^2 +4x) then do y+y-8
Answer:
B) 5
Step-by-step explanation:
Proportions:
8 ⇒ 10
20 ⇒ 5x
5x = 20*10/8
5x = 25
x = 25/5
x = 5
Answer:
I Disagree............................
X is the length
y is the width
2x+2y=66
x-y=15
multiply the second equation by 2 (elimination)
2x-2y=30
add the equations together
4x=96
x=24
Plug this in to one of the original equations
24-y=15
the width is 9
