Perimeter = 2L + 2W
since it’s a square, all sides are equal so
perimeter = 4s
s = 13
so multiply 13 by 4
perimeter = 13*4 = 52
Answer:
-22
Step-by-step explanation:
4 + 9 + (16 ÷ 4 - 8 - 3) × 5
= 13 + (4 - 8 - 3) × 5
= 13 - 7 × 5
= 13 - 35
= -22
<em><u>Total Cost : 1800</u></em>
<u><em>12 dollars * 16 hours = 192 dollars earned</em></u>
<u><em>0.2 percent * 192 = 38.4 dollars saved</em></u>
A.<u><em>She earns 192 dollars every week</em></u>
B. she will save <em><u>38.4 dollars * 7 weeks = 268.8 </u></em> dollars in a week.
C. 7 days times 4.3 weeks = 30.1 days. <em><u>30.1 days * 38.4 = 1,155.84 dollars every month.</u></em>
D. it will take her about <em><u>2 months</u></em> to save the money. <em><u>To be exact: 1.6 months.</u></em>

Think of 40 as 100% (even though it is not)
X will be the value we are looking for
<span> If 40 is 100%, so we can write it down as 40=100%.
</span>
<span>We know, that x is 64% of the output value, so we can write it down as x=64%
</span>
-----------------------------------------------
1) 40=100%
<span>2) x=64%
</span>----------------------------------------------
<span>40/x=100%/64%
</span>
40/x=100/64
(40/x)*x=(100/64)*x
40=1.5625*x -divide both sides of the equation by (1.5625) to get x-
40/1.5625=x
25.6=x
x=25.6
So we get;
64% of 40=
25.6
Let the number of collectible dolls she can buy be x.
x ≤ 45/2.5
x ≤ 18
