Answer:
the answer would be 3 hours
Step-by-step explanation: if she wants to spend $27 then she can only rent for 3 hours because 27 - 15 = 12 and 12 divided by 4 is three.
Inequality: y = 3x -15
Solution is 3 hours
Answer: its 4 miles per hour
Step-by-step explanation: we divide but that not all u do........
Answer:
a= sqrt. 495
or
a= 22.2485954613
Step-by-step explanation:
a^2+b^2=c^2
a^2+9^2=24^2
a^2+81=576
576-81=a^2
a^2=495
So lets say you have 10+2y=2x, first you subract 10 by both sides, now you got 2y=2x-10. Divide all the numbers by 2, and then you got y=x-5.
Answer: BC is 9 units long
==============================================================
Work Shown:
Let x be the length of segment BC.
BC is parallel to DE, so this means that triangle ABC is similar to triangle ADE.
Side AB pairs with side AD (both are horizontal sides of triangle ABC and triangle ADE respectively)
Side BC pairs with side DE (both are vertical sides of triangle ABC and triangle ADE respectively)
Because of those facts above, we can end up with this proportion
AB/AD = BC/DE
-------------------
Let's plug in the given values and isolate x
AB/AD = BC/DE
12/20 = x/15
12*15 = 20*x ... cross multiply
180 = 20x
20x = 180
20x/20 = 180/20 ... divide both sides by 20
x = 9
Segment BC is 9 units long.
note: There is no need to calculate the length of segment AE. Though you are correct in stating that AE = 25.
