Answer:
Yes
Step-by-step explanation:
With 32 inches of trim, she can trim a square that is 32/4 = 8 inches on a side. That square would have an area of 8² = 64 square inches. The square she has is 60 square inches, so is smaller. There will be sufficient trim for it.
Check the picture below.
let's recall that a square has all equal sides, so the perimeter of the square is about 31, and Alicia has 32 inches of trim, so she's golden.

y = The cost of a peach
6x + 9y = 7.86 - - - - - - - - 1
4x + 5y = 4.82 - - - - - - - - 2
From equation 2,
4x =4.82 - 5y
x= (4.82 - 5y) ÷ 4 - - - - - - - 3
Substitute 3 into 1,
6x + 9y = 7.86
6 [(4.82 - 5y) ÷ 4] + 9y = 7.86
(28.92 - 30 y) ÷4 + 9y = 7.86
28.92 - 30y + 36y = 31.44
6y=2.52
y= 0.42
Substitute y = 0.42 into 2
4x + 5y= 4.82
4x + 5 (0.42) = 4.82
4x + 2.1 = 4.82
4x= 2.72
x= 0.68.
Thus, an apple costs $ 0.68 and a peach costs $ 0.42.
B. if each student needs 7 balloons, how many more balloon are needed? Explain
Answers
10 balloons are left over after sharing them equally and 17 more balloons are needed
- Numbers of students learning to make balloon animal = 27
- Total balloon to be shared equally among the students = 172
Further Explanation
First step:
To determine how many balloons each student gets = the total balloons to be shared equally among the students divided by the number of students learning to make balloon animal.
Therefore, we have:
=
= 6.37
= 6 balloons (each student get 6 balloons)
Second step:
To get how many balloons will be used by the entire student, then we should multiply the number of balloon each student gets (6) and the numbers of students learning to make balloon animal (27)
Therefore, we have:
= 6 x 27
= 162 (162 balloon will be used by the student)
To calculate the remaining balloons, then we have to subtract the total balloons to be shared equally by the students and the numbers of balloon to be used by the entire students
Therefore, we have:
= 172 – 162
= 10 balloons.
Thus, 10 balloons are left over after sharing them equally.
Part B:
If each student needs 7 balloons, then 17 more balloons are needed.
Since we have 10 balloons left after sharing them equally, to determine how many more balloons are needed = total number of students learning to make balloon animal – the numbers of balloon left over after sharing them equally.
Therefore, we have:
= 27 – 10
= 17 balloons
Therefore, if each student needs 7 balloons, 17 more balloons are needed.
Another step:
Another way you could determine how many balloons are needed is to multiply the numbers of balloon each student needs and the total number of student learning to make balloons animals, and subtract the value you derived from the total balloon to be shared equally among the students.
Therefore, we have:
= 7 x 27
= 189 balloons
= 189 - 172
= 17 balloons.

To Check:
what I did was divide 172 by 27 and it is 6.37 rounded to ........6 is an equal number so I kept it and .4 will be left over after sharing equally.
B.) 17 more balloons are needs
To Check:
what I was multiply 27 by 7 because each student needs seven balloons and I got 189 after that I subtracted 172 from 189 (189-172=17)
to see how many more balloons are needed.
