Answer:
10x-15
Step-by-step explanation:
First, do Abbey. Abbey= 5 hrs less than 3 Emily.
Nathan spends twice as much as Abbey. Then you get 3x (Emily is x) -5 +x (for Emily) +6x - 10 (for Nathan. Add those. You get 3x+x+6x-5-10. I hope this is correct.
Answer:
9x^2 + 9x -70
Step-by-step explanation:
Use the distributive property to solve
(3x-7) (3x+10)
multiply 3x x 3x = 9x^2
multiply 3x(-7) and 3x(10)
add -21x + 30x = 9x
multiply -7 x 10 = -70
Answer:
thye amount in in the paint can is (7.9)
Step-by-step explan the graph height is )4.2)
The angles ACD and Angle ABE are congruent so there measure is equal.
3x+14=50
3x= 50-14
3x= 36
X= 36/3=12
Try this:
1. sum of numbers is x+y=67, the difference between them is x-y=11
2. it is possible to make up and resolve the system:
