Karrine hit 4 more home runs than half the number of home runs Lu hit. Together they hit 10 home runs. Let x represent the numbe

Andreas93 [3]

Answer:

The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6

Step-by-step explanation:

Let

x ----> represent the number of home runs Lu hit

y ---> represent the number of home runs Karrine hit

we know that

Together they hit 10 home runs

$x+y=10$ ----> equation A

Karrine hit 4 more home runs than half the number of home runs Lu hit

$y=\frac{1}{2}x+4$ ---> equation B

substitute equation B in equation A

$x+\frac{1}{2}x+4=10$

solve for x

$\frac{3}{2}x=10-4$

$\frac{3}{2}x=6\\x=4$

Find the value of y

$y=\frac{1}{2}(4)+4=6$

therefore

The number of home runs that Lu hit is 4 and the number of home runs that Karrine hit is 6

It should take 5.22 minutes to clean a shower. You have 5 showers that need to be cleaned. How many minutes should it take for y

Pie

This problem is simply multiplication as it is 5.22 minutes per shower. With this in mind, we can just multiply 5.22 by 5 and get our answer.

5.22
<u>x 5
</u>26.1

Using the math above, we can see that it should take 26.1 minutes to clean 5 bathrooms.
