Answer:
x=-14y
Step-by-step explanation:
9x+y=-5
x+y=-5-9
x+y=-14
x=-14y
47 - 19 = 28
28/4 = 7
At most they can spend 7 hours
The solution is
T = (47-19)/4
T = 28/4
T = 7
I think that solution is what your teacher is asking for, i'm not certain but ik the answer should be 7 hours.
C, 125. Hope I helped.
btw, u gotta do 35+30+25+20+15
Answer:
To get the area of a parallelogram
Step-by-step explanation:
A=bh is the formula for an area so option D is definitely wrong.
The formula for the area of a triangle is
.
The formula for the area of a circle is πr²
The formula for the area of a parallelogram is A=bh
A=bh is the formula for the area of a parallelogram.
Cary's age is 9 years MORE than Dan's age.
Cary's age is Dan's age, but with 9 more years added to that.
Here is how we can express that,

In 7 years, Cary will be C+7 years old,
and Dan will be D+7 years old.
In 7 years, the sum of their ages,
(C+7) and (D+7) will equal 93.
Here is how we can express that:

You have a system of two equations involving two unknowns. You have a couple of nice options here. You can apply substitution or elimination to complete the problem.
