Answer: 15 1/2
Step-by-step explanation: There are two 1/2 s so 1/2 + 1/2 is 2/2 or 1 whole. Next is 1. There are 4 ones. 1+1+1+1 = 4. There is one 1 1/2. There are two 2. 2+2 is 4. There are two 2 1/2 so 2 1/2 + 2 1/2 is 4 2/2 which is 5. Now you have to add all the answers together. 1 +4+ 1 1/2 +4+5 which is 15 and 1/2. 15 1/2 is the answer.
Answer:
88 ft
Step-by-step explanation:
Let's say the shortest piece has length 2x, so the medium piece has length 5x and the longest piece has length 8x. Added together, they equal 165, so
2x + 5x + 8x = 165
15x = 165
divide both sides by 15 to isolate x
x = 11
8x = longest piece = 88 ft
Answer: unit rate for calories per cup = 120
calories in 4 cups of cereal = 480
Solution:
Total number of calories in a box of cereal = x calories
Calories in 3/4 cup serving = 90
How many calories in 4 cups = c
How many calories per cup = x
Unitary method
Cups Calories
3/4 90
1 x
Corss multiply
3/4 * x = 90 * 1
x = 90 * 4/3
x = 120 calories
Now for 4 cups,
Cups calories
1 120
4 c
(Cross multiply)
1 * c = 120 * 4
c = 480 calories answer
