Answer:
C
Step-by-step explanation:
15 - 9 = 6, So I then looked at each answer to see which had a difference of 6 and 35 - 29 = 6.
GOOD LUCK IN MATH!
Let's say the distance is "x".
time = distance / rate
time1 = x / 40
time2 = x/80
A) time1 shoud be twice time2 or (time1 / time2) =2
B) time1 -1 = time2
Substituting equation B) into A)
((time1 / (time1 -1) = 2
time1 = 2* time1 -2
time1 = 2 hours time2 = 1 hour
Distance = 80 miles
1st trip time1 = 80/40 = 2 hours
return trip time2 = 80/80 = 1 hour
total trip = 160 miles in 3 hours
average speed = 53.333333 miles per hour
Answer:
x = 48
Step-by-step explanation:
First find y
52+y+59 = 180 since they from a straight line
y = 180-59-52
y = 69
Then we know the angles of a triangle add to 180
x+y+63 = 180
x+69+63 = 180
x = 180-69-63
x =48
Given:
The expression is:

To find:
The value of the given expression when
and
.
Solution:
We have,

Putting
and
, we get

It can be written as

![[\because a^0=1,a\neq 0]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%5E0%3D1%2Ca%5Cneq%200%5D)


Therefore, the value of the given expression
when
and
.
If he needs $20, for a truck only has 10 and spends $2 already. He only has $8 left which means he needs a minimum of $12. So I'd say best guess. C or D.
