Greater than 100 but less than 150
Answer:
y=7
Step-by-step explanation:
The two given angels are congruent so they must be equal in measure.
Set them up equal and find y.
8y = 5y + 21, subtract 5y from both sides
8y -5y = 21, combine like terms
3y = 21, divide both sides by 3
y = 7
Answer:
28
Step-by-step explanation:
The product of -4 and the unknown number n is -4n.
4 more than the product of -4 and the unknown number n is -4n + 4.
Letting n = -6 results in the value -4(-6) + 4, or 24 + 4, or 28.
Y is directly proportional to x and therefore takes the form y=kx where k is the constant of proportionality.
Dividing both sides by x for the given values, k becomes 18/4 = 4.5
