Solve the proportion five point two over eight = y over six A. y = 4.22 B. y = 6.93 C. y = 2.86 D. y = 3.90
1 answer:
Answer:
D.y = 3.9
Step-by-step explanation:
we can express the word problem five point two over eight = y over six mathematically;
our unknown is y, so we will keep rearranging the equation by using simple principles of algebra until we get y
cross multiply;
y×8 =5.2×6
y×8 =31.2
divide through by 8
y×8÷8 =31.2÷8
y=3.9
The correct answer is D
