Answer:
C. x + 5 = (x + 5) − 5, which has no solution
Step-by-step explanation:
Jenna's age Jessica's age
today x x + 5
in 5 years x+5
5 years ago x + 5 - 5
Equality x + 5 = x + 5 - 5
=> x + 5 = x
The equation is x + 5 = ( x + 5 ) -5
System of Equations:
let these two numbers be x and y
x+y = 82
x-y = 29
If you add the two equations you can eliminate y.
2x = 111
x= 55.5
Plug x back into one of the two equations. So the two numbers are 55.5 and 26.5.
Answer:
300 miles
Step-by-step explanation:
Since Jess can drive 200 miles on a 1/2 of a tank of gas that must mean he can drive 100 miles with his gas tank only 1/4 full. Since he needs to know how far he can drive with his gas 3/4 of the way full he would just add 200 miles to 100 miles and get 300 miles.
You figure this out by dividing 200 miles by 2 since it is a half way full and you just need to half the amount of miles to get how many miles it is for a fourth of the way full. You would need to find out how much it is for a fourth of the way full since it only says Jess can drive 200 miles on a 1/2 tank of gas. However we need to find out how far he can drive with 3/4 tank of gas. Which you know that you need to find out how much it is for a fourth of a tank of gas or 1/4 since 1/2 is also equal to 2/4 and 1/4 plus 2/4 is equal to 3/4.
I hope this helps! If you need any more further help with this question let me know.

55
Step-by-step explanation:
Answer:
Angle B = 120.5°
Step-by-step explanation:
When two angles are supplementary, it means that they add up to 180°. Therefore, you can find the measure of Angle B by doing the following:
Angle B = 180 - 59.5
Angle B = 120.5°
