Answer: $36.69


Step-by-step explanation:

Okay, so let's first write the equation:

2.59*10 + 3d = 135.97

Now, let's work on isolating d by first simplifying the equation:

25.9 + 3d = 135.97

25.9 + 3d - 25.9 = 135.97 - 25.9

3d = 110.07

3d/3 = 110.07/3

d = 36.69

Okay, now let's check:

2.59*10 + 3*36.69  = 135.97

25.9 + 110.07 = 135.97

135.97 = 135.97

Okay, so so it costs $36.69 per pair of shoe.

abruzzese [7]

Answer:

<u>15 students</u> purchase their lunches in the cafeteria.

Step-by-step explanation:

Given:

At eastwood middle school, 25% of the 60 students Mrs. Wade teaches buy their lunches in the cafeteria.

Now, to find the students purchase their lunches in the cafeteria.

Total students = 60.

Percent of students who buy lunches = 25%.

So, to get the number of students who buy their lunches in the cafeteria:

<u><em>25% of 60.</em></u>

=\frac{25}{100} \times 60

=0.25\times 60

=15.

Therefore, 15 students purchase their lunches in the cafeteria.

I think it's 138 Long by 109.5 more accurate .
92/73 = 1.26
120/100 = 1.2
138/109.5 =1.26
Hence 138 by 109.5 is more proportionate

A rectangular park has an area of 6 square miles. The width of the property is 3/8 the length of the property. What is the width
Olegator [25]
Area = width * length

if width = 3/8 length ⇒ length = 8/3 width

area = width * 8/3 width = 8/3 width² = 6

width² = \frac{6*3}{8} =  \frac{3 * 3}{4} =  \frac{9}{4}

width = \sqrt \frac{9}{4} =  \frac{3}{2}
