Answer:
When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour
Step-by-step explanation:
Ex: If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
120/3 = 40/1
The unit rate of 120 students for every 3 buses is 40 students per bus. You could also find the unit rate by dividing the first term of the ratio by the second term.
Answer:
8 footballs
18 basketballs
36 baseballs
24 softballs
Step-by-step explanation:
Let f = footballs
f = 8
Let b = basketballs
b = 2+2f = 2 +2(8) = 2 +16 = 18
Let B = baseballs
B = 5f -4 = 5(8) -4 = 40-4 = 36
Let s = softballs
s = 6+1/2B = 6+1/2(36) = 6+18 = 24
The total is 86
f+b+B +s = 86
8+18+36+24 = 86
86=86
Answer:
Step-by-step explanation:
Answer:
4(2x+2)=8(2-3x)
First I am going to distribute the 4 and the 8 on the sides of the equation.
This gets me to
8x + 8 = 16 - 24x
then subtract 8x on both sides to get
8 = 16 - 16x
then subtract 16 on both sides to isolate the -16x
-8 = -16x
then divide by -16 on both sides, to make the x variable positive and isolate the variable even more.
0.5 = x
