Answer:
2 hours
Step-by-step explanation:
variable x = hours
fix it fast: 25 + 50x
do it right: 35 + 45x
25 + 50x = 35 + 45x
subtract 45x from both sides
subtract 25 from both sides
(this action cancels out 45x on the right side and 25 on the left side so you can combine like terms)
50x - 45x = 35 - 25
5x = 10
divide by 5 on both sides
x = 2
I would do 10x10-8x8 which is 36 which is 6 times it self
So A=6 in.
Answer:
-84/3
Step-by-step explanation:
Here we are given the expression:
Now we have to find the value of this expression when x equals -9.
So plugging the value of x as -9 in the given expression:
=
=84/-3
So on evaluating we get the value of expression as -84/3.
For this case we have to, so that both runners finish at the same time, Dave must also reach 88 seconds.
With respect to the times we have:
Dave must have a 33-second disadvantage.
This means that in those 33 seconds of difference Jack runs:
So, Dave must lose 165 yards to get to Jack
Answer:
165
7x + 5 = -58
+ 5 represents 5 more than
7x represents 7 times a number
