Answer:
x = 350 gallons (amt of 60% solution that must be added)
Step-by-step explanation:
Amt of 60% solution = x gallons ; Amt of active ingredient = 0.6x gallons
Amt of 15% solution = 100 gallons ; Amt of active ingredient = 15 gallons
Amt of 50% solution = 100+x gallons ; Amt of active = 50 + 0.5x gallons
EQUATION:
Active ingredient: 0.60x + 15 = 50 + 0.50x
0.10x = 35
x = 350 gallons (amt of 60% solution that must be added)
Answer:
13 and 32
Step-by-step explanation:
let one number be x
Then the other number is x + 19 , then
x + x + 19 = 45
2x + 19 = 45 ( subtract 19 from both sides )
2x = 26 ( divide both sides by 2 )
x = 13
The 2 numbers are 13 and 13 + 19 = 32

Step-by-step explanation:
There are a couple of things about this question that bother me.
1). BOB11111111 copied the question but didn't take the time to give us
the picture that goes with it. That bothers me.
2). If ABC is a triangle, then ABC cannot be a line. That also bothers me.
As it is, there's no way for anyone to answer the question without more
information than what we have here.
Step-by-step explanation:
let total pizzas = y
so
32/100 x y = 64
y= 64× 100/32
= 200 pizzas
