Answer:
20 pictures.
Step-by-step explanation:
In this question, we need to find out how many pictures Milan printed.
We know that the film processing costed $4.95 and each picture that was printed costed $0.35.
Lets turn this into an equation with x representing the amount of pictures:
y = 0.35x+ 4.95
Now we need to solve the equation. We can do this by plugging in our known cost, 11.95, into "y".
Solve:
11.95 = 0.35x + 4.95
Subtract 4.95 from both sides.
7 = 0.35x
Divide both sides by 0.35
20 = x
Milan printed 20 pictures.
Negative exponents create the reciprocal of the original number:
2^2=4
2^-2=1/4
4^4=64
4^-4=1/64
Answer:
x=9, y=10. (9, 10). The two numbers are 9 and 10.
Step-by-step explanation:
3x+5y=77
x+y=19
------------------
3x+5y=77
-3(x+y)=-3(19)
---------------------
3x+5y=77
-3x-3y=-57
-------------------
2y=20
y=20/2
y=10
x+10=19
x=19-10
x=9
