Answer:
Length = 21 yards
Width = 15 yards
Step-by-step explanation:
Let
Length = x
Width = x - 6
Perimeter ≤ 71 yards
Perimeter of a rectangle = 2 (length + width)
72 ≤ 2(x + x-6)
72 ≤ 2 (2x - 6)
72 ≤ 4x - 12
72 + 12 ≤ 4x
84 ≤ 4x
x ≤ 84/4
x ≤ 21
Length = x = 21 yards
Width = x - 6
= 21 - 6
= 15 yards

Sarah sold 66 posters
<em><u>Solution:</u></em>
Let "a" be the number of shirts sold
Let "b" be the number of posters sold
<em><u>Sarah sold a total of 178 t shirts and posters at a festival</u></em>
Therefore,
number of shirts sold + number of posters sold = 178
a + b = 178 ----------- eqn 1
<em><u>She sold 46 more tshirts than poster</u></em>
Number of shirts sold = 46 + number of posters sold
a = 46 + b --------- eqn 2
<em><u>Substitute eqn 2 in eqn 1</u></em>
46 + b + b = 178
2b = 178 - 46
2b = 132
b = 66
Thus she sold 66 posters
Answer:
a = 84/14
Step-by-step explanation:
The next step you would divide by 14 to get a=6 so I think the program wants you to input a = 84/14
First you have to multiply 1,500 by 65%. A way to do that is 1,500 x 65 and then divide by 100.
So 1,500 x 65 is 97,500.
97,500 divided by 100 is 975.
The final answer is that there are 975 girls in the school.
