Answer:
a= 68% times 250, there are 170 students not in Advanced
Step-by-step explanation:
If 32% are in Adv math, 68% aren't, to solve a percentage, I did
.68 times 250
Answer:
Answer 2
Step-by-step explanation:
the number are being added together based on their position
Use this systems of equations to solve:
x = first antifreeze
y = second antifreeze
Isolate y.
x + y = 15
Subtract x from both sides.
y = -x + 15
Substitute y into the other equation.
.2x + .12(-x + 15) = .18(15)
Simplify.
.2x - .12x + 1.8 = 2.7
Subtract 1.8 from both sides.
.08x = .9
Divide both sides by .08
x = 11.25
Substitute x in the equation that we isolated y in.
y = -11.25 + 15
y = 3.75
11.25 L of the first antifreeze and 3.75 L of the second.
