Answer:
x=120cc volume of 7% solution
Step-by-step explanation:
Saline solution(7% solution) +
Saline solution (19% solution) = Saline solution (11% solution)
Saline solution(7% solution): (0.07)(x)
x= unknown volume
Saline solution (19% solution): (0.19)(60)
60= given volume
Saline solution (11% solution)= (0.07)(x+60)
x+60= Total volume
solve for x
(0.07)(x) + (0.19)(60) = (0.11)(x+60)
0.07x +11.4 = 0.11x + 6.6
0.11x - 0.07x = 11.4 - 6.6
0.04x = 4.8
x = 4.8/0.04
x = 120 cc volume of 7% solution
Answer: Todd earned $40 mowing the neighbor's lawn.
Step-by-step explanation:
Let x represent the amount of money that Todd earned, mowing his neighbor's lawn.
He spent one-fourth of his money see a movie. It means that the amount spent in seeing a movie is x/4
Then he spent $6.00 on popcorn and drinks. It means that the total amount spent is
x/4 + 6
The amount left would be
x - (x/4 + 6) = x - x/4 - 6
When he went home, he had $24.00 left. It means that
x - x/4 - 6 = 24
x - x/4 = 24 + 6
x - x/4 = 30
Cross multiplying by 4, it becomes
4x - x = 120
3x = 120
x = 120/3
x = $40
Answer:
C.
Step-by-step explanation:
It is parallel? This is what I would put
Step-by-step explanation:
There are many possible solutions. For example:
3x + 0 = 1x + 4
4x + 1 = 2x + 5
5x + 2 = 3x + 6
