Answer:

a. 280/800 (or 7/20 simplified)

b. 520/800 (or 13/20 simplified)

Step-by-step explanation:

a. 800 × 0.35 = 280

Fraction of girls = total girls/total enrollment = 280/800 (or 7/20 simplified)

b. Total boys = Total enrollment - total girls = 800 - 280 = 520

Fraction of boys = total boys/total enrollment = 520/800 (or 13/20 simplified)

Which expressions are equivalent to 7 (negative three-fourths x minus 3)? Select two options.
polet [3.4K]

<em><u>The equivalent expressions are:</u></em>

7(-\frac{3}{4}x - 3) = (7 \times \frac{-3}{4}x) + (7 \times -3)\\\\7(-\frac{3}{4}x - 3) = \frac{-21x}{4} - 21

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

7(-\frac{3}{4}x - 3)

We have to find the equivalent expressions

By distributive property,

a(b + c) = ab + ac

Therefore,

7(-\frac{3}{4}x - 3) = (7 \times \frac{-3}{4}x) + (7 \times -3)\\\\7(-\frac{3}{4}x - 3) = \frac{-21x}{4} - 21

Thus equivalent expressions are found

1. I feel the need to explain things first before I write the numeric value. 
   Let x be the total number of students in the school. 25% of this value is given to be 35.
                        (0.25)x = 35
The value of x is 140. 75% of this value is the answer which is equal to 105.

2. Let y be the alternative schools. With this, the number of charter schools is 2x - 6 which is equal to 52 
                              2x - 6 = 52
The value of x is 29. Therefore, there are 29 charter schools.
