Hi, I'm happy to help!
First off, we need to arrange an equation for what is being asked. 15 is 20% of her earnings and we don't know her total earnings.
15=20%×__
We can write this percentage as
15=0.2×__
We then change the equation to do the inverse operation, which is division, this makes it easier to solve.
15÷0.2=__
Now, we solve
15÷0.2=75
<u>She earned $75</u>
<u></u>
I hope this was helpful, keep learning! :D
rearrange the equation so like terms are together: 5a-a+6a+12-12
+12 and -12 cancel out, so: 5a-a+6a
subtract: 4a+6a
add: 10a
Hello!
To find the surface area of a rectangular prism you use the equation
SA = 2(wl + wh + lh)
SA is surface area
w is width
l is length
h is height
Put in the values you know
SA = 2(4.5 * 16 + 4.5 * 29 + 16 * 29)
Multiply
SA = 2(72 + 130.5 + 464)
Add
SA = 2(666.5)
Multiply
SA = 1333
The answer is 1333 cm squared
Hope this helps!
