The ratio of girls to boys in Mr. Smith's homeroom is 3:4. The ratio in Mr. Smith's homeroom to students in the whole 7th grade

Leno4ka [110]

3:4 = G:B

1:5 = Mr. Smith's class: 7th Grade

2:7= 7th: Middle school

12 girls = 3 units

1 unit = 12/3= 4

Boys = 4x4= 16

<em>Whole class = 28 students</em>

Class : Grade = 1:5 <em> 7 = number of units in Mr. Smith's class</em>

28 = 1 unit

5 units= 28x5= 140 <em>There are 140 kids in the grade</em>

140 = 2 units

1 unit = 140/2= 70

70x7=490

<u><em>There are 490 students in the whole grade</em></u>

Which is a correct two-column proof? Given: <H and <X are supplementary. prove: l || n

andriy [413]

Answer:

option-B

Step-by-step explanation:

we are given

<H and <X are supplementary angles

so,

<H+<X=180

we know that

<H and <E are vertically opposite angles

so, they must be equal

<H=<E

we can plug it

<E+<X=180

It means that angle(E) and angle(X) are supplementary angles

and these two angles are same side interior angles

By using same side interior angles converse

so, line(l) and line(n) must be parallel

so, option-B

Rae runs 4 times as many miles as Madison and Aaliyah combined. Madison runs m miles, and Aaliyah runs a miles.

mash [69]

Answer: $4(m+a)$

Step-by-step explanation:

<h3> The complete exercise is: "Write an expression using letters and/or numbers for each problem below"</h3>

For this exercise it is necessary to remember the following:

1. The word "times" indicates multiplication,

2. The word "combined" indicates addition.

In this case let "m" represents the amount of miles that Madison runs and let "a" represents the amount of miles that Aaliyah runs.

Based on the explained above, you know if the amount of miles that Madison runs and the amount of miles that Aaliyah runs are combined (or in other words, they are added), then the expression that represents this would be:

$m+a$

Therefore, you can determine that "4 times as many miles as Madison and Aaliyah combined", can represented with the following expression:

$4(m+a)$
