Answer:

48 = 12y

Step-by-step explanation:

First, we simplify

6 * 7 = 42

6 * 3y = 18y

6 * y = 6y

6 * 1 = 6

Then, rewrite the expression

42 - 18y + 6y + 6

Now, rearrange the expression

42 + 6 - 18y + 6y

Then, simplify

48 - 12y

Hope this helps!

Answer:

48 - 12 y

Step-by-step explanation:

6 (7 - 3 y) + 6 (y + 1)

Use distributive property to get rid of the parentheses:

42 - 18 y + 6 y + 6

now combine like terms:

(42 + 6 ) + (- 18 y + 6 y) = 48 - 12 y

Answer:

a=5

Step-by-step explanation:

1. Multiply 4 and 6a by 4.

You'll get 24a + 16.

2. Subtract 16 from 136.

You'll get 120.

3. Divide 120 by 24 to get <em>a</em> by itself.

Students surveyed boys and girls separately to determine whether they wanted outdoor
vazorg [7]

Answer:

111 girls

Step-by-step explanation:

Given

Boys: Every 17 outdoor ≈ 20 indoor

Girls: 3:2 outdoor to indoor

First, we'll determine the ratio of outdoor to indoor for boys;

Recall that;

17 choose indoor while 20 choose outdoor;

The ratio of outdoor to indoor is;

20 : 17

Convert to fraction:

\frac{20}{17}

Let x represent number of boys that choose indoor when 85 boys chose outdoor;

The ratio of outdoor to indoor is;

x : 85

Convert to fraction

\frac{x}{85}

Equate both fractions

\frac{20}{17} = \frac{x}{85}

Multiply both sides by 85

85 * \frac{20}{17} = \frac{x}{85} * 85

85 * \frac{20}{17} = x

\frac{1700}{17} = x

100 = x

x = 100

This implies that when 85 chose outdoor, 100 chose indoor for boys;

Total = 100 + 85

Total = 185 boys surveyed

<em>Recall that the question says the same number of boys and girls were surveyed</em>

This implies that

Total Girls Surveyed = 185

For the girl ratio;

Outdoor to Indoor= 3:2

Number of girls that chose outdoor is as follows;

Outdoor = \frac{3}{3 + 2} * Total

Outdoor = \frac{3}{3 + 2} * 185

Outdoor = \frac{3}{5} * 185

Outdoor = \frac{555}{5}

Outdoor = 111

<em>Hence, the number of girls that chose outdoor is 111</em>
