2(4w+7)=62 <br><br> Whats the answer how do I do it?
blondinia [14]

2(4w + 7) = 62

Divide both sides by 2

\frac{2(4w + 7)}{2}  =  \frac{62}{2}  \\

4w + 7 = 31

Subtract both sides 7

4w + 7 - 7 = 31 - 7

4w = 24

Divide both sides by 4

\frac{4w}{4}  =  \frac{24}{4}  \\

w = 6

Stells [14]
<h3>Given:</h3>

The ratio of number of girls and boys in a class of 30 students is 7:8

<h3>To Find:</h3>

The ratio of number of girls and boys if 5 new boys admit in the class.

<h3>Assumption:</h3>

Let the number of students be x.

<h3>Solution:</h3>

According to the question,

7x + 8x = 30

or, 15x = 30

or, x = \large {\tt {\frac{30}{15}}}

or, x = 2

7x = 7(2) = 14

8x = 8(2) = 16

There were 14 boys and 16 girls in the school.

After admitting 5 new boys, we get

14 + 5 = <u>19</u>

The ratio of number of girls and boys now is 16:19.

<h2>Answer:</h2>

<u>1</u><u>6</u><u>:</u><u>1</u><u>9</u>

What is the distance between (6,2) and (-3,-2)
SSSSS [86.1K]

Answer:

\sqrt{97}

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (6, 2) and (x₂, y₂ ) = (- 3, - 2)

d = \sqrt{(-3-6)^2+(-2-2)^2}

   = \sqrt{(-9)^2+(-4)^2}

   = \sqrt{81+16}

   = \sqrt{97} ≈ 9.8 ( to 1 dec. place )
