Answer:
or ![2\frac{1}{8}](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B8%7D)
Step-by-step explanation:
First we will convert the first term into an improper fraction. We multiply the whole number into the denominator and add the product to the numerator.
![2\frac{1}{2}](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B2%7D)
![-\frac{3}{8}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B8%7D)
![\frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D)
![-\frac{3}{8}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B8%7D)
Then we will multiply the first term by 4/4 to match the denominator of the second term..
*
= ![\frac{20}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B8%7D)
Finally we subtract.
![\frac{20}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B8%7D)
= ![\frac{17}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B8%7D)
Answer: B
Step-by-step explanation: 6^2 = 36
36*4= 144
144-7= 137
Answer:
c = -3
Step-by-step explanation:
Call the unknown c
c(x-3) +2x = -(x-5) +4
Distribute the negative sign
c(x-3) +2x = -x+5+4
Combine like terms
c(x-3) +2x = -x +9
Subtract 2x from each side
c(x-3) +2x-2x = -x-2x +9
c(x-3) = -3x+9
Factor a -3 from the right side
c(x-3) = -3(x-3)
Divide by (x-3)
c = -3
The right and left hand side need to be equal for there to be infinite solutions, so c = -3
Answer:
ok so first he drives 3 hours
then he drives for the same amount plus a hour so 3+1=4
he drives for 4 more hours
then he stops and drives some more 3+4=7
hes driven 7 hes driving for 9 in to total so his last segment is 2 hours.
2 hours
Hope This Helps!!!
