Step-by-step explanation:
x=180-(110+55)=15
the answer for your question
is b.25
Answer:
$12.09
Step-by-step explanation:
formula; Y= kx
where; y = $24.18
x = 2 books
k = constant of proportionality
Step 1. Do the equation based on the data given
Y = kx
$24.18 = k2
Step 2. Compute the mathematical equation. Divide both sides by 2 to eliminate coefficient in the variable.
<u>24.18 =k2</u>
2
k = $ 12.09 is the constant of proportionality cost in dlooars per book
-5 - (-7) = -5 + 7 (Answer D)
The ratio would be 3 pears : 9 apples = 3:9 which reduces to 1:3
