Step-by-step explanation:
6(y+2) = 4(z+9)
6y + 12 = 4z + 36
6y = 4z + 24
y = (4z + 24) / 6
y = (2z + 12) / 3
answer
C. y = (2z + 12)/3
Answer:
36 and 144
Step-by-step explanation:
Sum the parts of the ratio, 2 + 8 = 10 parts
Divide the sum of the 2 numbers by 10 to find the value of one part of the ratio.
180 ÷ 10 = 18 ← value of 1 part of the ratio, thus
2 parts = 2 × 18 = 36
8 parts = 8 × 18 = 144
Thus 2 numbers are 36 and 144
