2. $9.20 cause you multiply the price by the number of the sweets
Answer- 2 hours
6.50+3= 9.50
9.50•3= 28.5
54.50-28.50= 26
26/2= 13
13/ 6.50= 2
Answer:
39/10
3 9/10
3.9
Step-by-step explanation:
Convert the mixed number to an improper fraction
1. P = 2(9) + 2(4.5)
P = 18 + 9
P = 27 m
2. P = 5.2(2) + 1.3(2)
P = 10.4 + 2.6
P = 13 ft
3. P = 12.9(2) + 4.7(2)
P = 25.8 + 9.4
P = 35.2 cm
Answer:
20x² - 43xw + 21w²
Step-by-step explanation:
We use FOIL to expand the expression:
F - First
4x(5x) = 20x²
O - Outside
4x(-7w) = -28xw
I - Inside
-3w(5x) = -15xw
L - Last
-3w(-7w) = 21w²
20x² - 28xw - 15xw + 21w²
Combine like terms and add up using correct signs and you should get your answer.
