Multiply the number of tosses by the percent of heads:
20 tosses x 0.75 = 15
The answer is 15.
Answer:
5x and -7x
Step-by-step explanation:
they both end in the variable "x"
x + 13 + 4x + 2 = 180
Add the like terms,
5x + 15 = 180
Subtract 15 form both sides
5x + 15 - 15 = 180 -15
5x = 165
Divide both sides by 5
5x/5 = 16/5
x = 33
1.25
Find the average.
-5.1+7.6=2.5
2.5/2
