This kind of problem assumes that the two people working together work for the same amount of time.
Renee can sew a quilt in 16 hours, so she can sew 1/16 of a quilt each hour. Gerena sews a quilt in 12 hours, so she can sew 1/12 of a quilt each hour.
Use the variable t represent the time Renee and Gerena work together (measured in hours). The part of a quilt Renee sews is . the part of the quilt that Gerena sews is
Together, they sew one quilt, so
Multiply all the terms by 48 (the Least Common Multiple of 16 and 12).
hours.
Answer:
13 is the answer:)
Step-by-step explanation:
f(-2)= 3* (-2)² + 1
= 3*4 + 1
= 13
Write an equation system based on the problem
For an instance, e stands for the price of a carton of eggs, and b stands for the price of a loaf of bread
"Kate bought 3 cartons of eggs and 5 loaves of bread for $30.07" could be written as 3e + 5b = 30.07 (first equation)
"Melissa bought 2 cartons of eggs and 2 loaves of bread for $14.74" could be written as 2e + 2b = 14.74 (second equation)
Solve the equation system using elimination method
Eliminate b to find e. To eliminate b, we should equalize the coefficient of b.
3e + 5b = 30.07 (multiplied by 2)
2e + 2b = 14.74 (multiplied by 5)
-------------------------------------------
6e + 10b = 60.14
10e + 10b = 73.70
------------------------- - (substract)
-4e = -13.56
e = -13.56/-4
e = 3.39
The price for a carton of eggs is $3.39
Answer:
Percentage of x free throws =
Step-by-step explanation:
We are given the following in question:
Total number of throws = 50
Number of free throws made = 42
Percentage of x free throws made is given by:
Putting x = 42, we get,
Percentage of free throws made =
Thus, Liam made 84% free throws this morning.
