The number of volunteers to walk dogs at the local animal shelter last year was 20 this year the number of volunteers has risen
Alex73 [517]

There is 150% increase in the number of volunteers.

Step-by-step explanation:

Given,

Old number of volunteers = 20

New number of volunteers = 50

Change = New value - Old value

Change = 50 - 20 = +30

The positive sign indicates the increase.

Percent increase = \frac{Change}{Old\ value}*100\\

Percent\ increase=\frac{30}{20}*100\\\\Percent\ increase=\frac{3000}{20}\\\\Percent\ increase=150\%

There is 150% increase in the number of volunteers.

Y=4x -1 and 12x=3y+7
Yuki888 [10]
You didn't really ask a question, so I'm assuming you want to know if there are any solutions to BOTH equations.

Use the first equation to substitute 4x - 1 for y in the second equation:

12x = 3(4x - 1)+7
12x = 12x - 3 + 7
12x = 12x +4
0 = 4

The last equation is FALSE, indicating the system of two equations has no solution.

What is the value of x in the equation 5x-7=28
fredd [130]

5x -7 = 28

Add 7 to both sides:

5x = 35

Divide both sides by 5:

X = 7

The answer is x = 7

Drag each number to the correct location on the equations. Each number can be used more than once, but not all numbers will be u
VARVARA [1.3K]

Answer:

<em>a=$10</em>

<em>c=$3</em>

Step-by-step explanation:

Step one:

given data

let adults tickets be a

and child tickets be c

so

Roy's purchase

6a+2c=66------1

Elisa's purchase

5a+4c=62-------2

Hence,  the system of equations

<em>6a+2c=66------1</em>

<em>5a+4c=62-------2</em>

<em>solving simultaneously</em>

<em>6a+2c=66------1 x2</em>

<em>5a+4c=62-------2 x1</em>

<em />

<em>   12a+4c=132</em>

<em>  -5a+4c=62</em>

<em>    7a=70</em>

<em>divide both sides by 7</em>

<em>a=$10</em>

<em />

<em>put  a=70 in 1</em>

<em>6(10)+2c=66------1</em>

<em>60+2c=66</em>

<em>2c=66-60</em>

<em>2c=6</em>

<em>c=$3</em>
