Answer:
Step-by-step explanation:
It is a special type of ratio
EXAMPLE:
12 ounce can of corn costs $.69 the rate would be $.69 for 12 ounces would be .69:12
Printer A prints for 10 minutes, so prints
... (30 pages/minute)×(10 minutes) = 300 pages
Printer B prints for 7 minutes, so prints
... (40 pages/minute)×(7 minutes) = 280 pages
At the end of 10 minutes, the two printers will have printed
... 300 pages + 280 pages = 580 pages
700x + 375(27 - x) = 15000
Solve for x
X=15 business class
Economy class 27-15=12
Answer:
Step-by-step explanation:
this has bean simplifyed dow to
= -1/6
3x+y=−11
3x+y+−3x=−11+−3x(Add -3x to both sides)
y=−3x−11
2x+2y=−10
2x+2(−3x−11)=−10
−4x−22=−10(Simplify both sides of the equation)
−4x−22+22=−10+22(Add 22 to both sides)
−4x=12
−4x
−4
=
12
−4
(Divide both sides by -4)
x=−3
y=−3x−11
y=(−3)(−3)−11
y=−2(Simplify both sides of the equation)
Answer:
x=−3 and y=−2
D.(-3,-2)
