Step-by-step explanation:
Let x represent the speed of the slower plane. The faster plane's speed is then x+40. The sum of speeds is ...
x + (x+40) = 1180
2x = 1140 . . . . subtract 40
x = 570 . . . . . .divide by 2
x+40 = 610 . . . . the speed of the faster plane
The two speeds are 570 mph and 610 mph.
Answer:
Maggie's ballon is 12 high.
Step-by-step explanation:
We are asked to find the y-value, and the x-value is given:
Plug the values in to solve for y.
y = -(2)^2 + 17(2) - 42 y
= -(4) + 34 - 42 y
= -4 + 34 - 42 y
= -12
The negative sign tells the direction. It is negative because the ballon is in the opposite direction.
Answer: Okay so let's try to find the amount of money needed to buy 1 lb. Therefore, let's divide the fraction by 14.

14÷14=1 2.99÷14=.2135 We can round that to .21
The unit rate for each pound would be 1:.21
