<span>The answer is 167 milliliters of 7% solution and 333 milliliters of 4% solution x + y = 500 x = 500 - y 0.07x + 0.04y = 25 (substitute 500 - y for x) 0.07(500 - y) + 0.04y = 25 35 - 0.07y + 0.04y = 25 -0.03y + 35 = 25 -0.03y = -10 y = 333.333... y [ = about 333 x = 500 - y = 500 - 333 = 167 hope it helps </span>
-1 and 15
The pattern is + 8
I think it is c) but when you turn it into a mixed number you get a different number or mixed number if it is not c) it is d)
Hope this helps! T-T
Let us assume the total number of eggs that each girl had to paint initially = x
Total number of girls that were scheduled to paint the eggs = 60
Number of girls that feel sick = 3
The number of girls that were finally there for painting the eggs = 60 - 3
= 57
Then we can write the equation as
57(x + 8) = 60x
57x + 456 = 60x
60x - 57x = 456
3x = 456
x = 456/3
= 152
So it can be seen that each girl had to paint 152 eggs
Then
The total number of eggs the girls had to paint = 60 * 152
= 9120
So a total of 9120 eggs had to be painted by the girls.
Answer:
Step-by-step explanation:
y = k*x This is the formula for a direct variation.
- y = 20
- x = 4 Substitute these values into the direct variation
20 = 4 * k Divide by 4
20/4 = 4k/4
k = 5
Answer: the constant of variation is 5
