Answer:
A 4* (7 - 3)
Step-by-step explanation:
Let's do this part by part. First we have "subtract 3 from 7:" this means we are taking 3 out of 7.
7 - 3
Next we have "then multiply by 4." So we need to take the above quantity and multiply the whole thing by 4.
(7-3) x 4
or
4 * (7-3)
The answer is A.
Here you're being asked to find the "perimeter" of the space, even tho' the problem doesn't specifically ask for it.
The formula for P is P = 2W + 2L.
Here the width, W, is 3 1/2 yds, and the length, L, is 4 2/3 yds. Subbing these two values into the formula for P (above) results in:
P = 2(3 1/2 yds) + 2(4 2/3 yds)
= 7 yds + 9 1/3 yds = 16 1/3 yds, total.
I forgot how to do this in middle school_
13: multiply the amount by the tax rate (to make a percent a decimal move the decimal point 2 places to the left) and add the original amount and the taxed amount together. For 12 do above but then multiply the total by the tip rate and add together (basically the same as the tax again) :) I hope this helps
