Answer:
18
Step-by-step explanation:
168 : 28 : : 108 : y
168 / 28 = 108 / y
6 = 108 / y
6 * y = 108
y = 108 / 6
y = 18
Answer:
complete the missing value in the solution
Step-by-step explanation:
Simplifying
6x + 7y = 4x + 4y
Solving
6x + 7y = 4x + 4y
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
6x + -4x + 7y = 4x + -4x + 4y
Combine like terms: 6x + -4x = 2x
2x + 7y = 4x + -4x + 4y
Combine like terms: 4x + -4x = 0
2x + 7y = 0 + 4y
2x + 7y = 4y
Add '-7y' to each side of the equation.
2x + 7y + -7y = 4y + -7y
Combine like terms: 7y + -7y = 0
2x + 0 = 4y + -7y
2x = 4y + -7y
Combine like terms: 4y + -7y = -3y
2x = -3y
Divide each side by '2'.
x = -1.5y
Simplifying
x = -1.5y
Answer:$125
Step-by-step explanation:
50% of 250
50/100 x 250
1/2 x 250=(1x250)/2=250/2=125
165 rounded to the nearest front (the hundreds place for all of them in this case) is 200. 123 rounded to the nearest hundred is 100, 376 rounded to the nearest hundred is 400, and 134 rounded to the nearest hundred is 100. Adding 200 + 100 + 400 + 100, we get 800.
