Find the solution:<br> 3x + 2y = 12<br> -2x + 3y = 5
finlep [7]

Answer:

x = 3

y = 2

Step-by-step explanation:

3x + 2y = 12

-2x + 3y = 5 to find the solution we will use elimination method and for that, multiply second equation with 3 and the first equation with 2

<em>2 * 3x + 2y = 12</em>

<em>6x + 4y = 24</em>

<u>3 * -2x + 3y = 5</u>

<u>-6x + 9y = 15</u>  now find the sum of both equation:

<em>6x + 4y  </em><u>-6x + 9y</u> = 24 + 15 add like terms

13y = 39 divide both sides by 13

y = 3 now that we found the value of y we can use this to calculate the value of x

3x + 2y = 12 replace y with 3

3x + 2*2 = 12

3x + 4 = 12 subtract 4 from both sides

3x = 9 divide both sides by 3

x = 3

Ayodele received a raise in her hourly pay, from $24.50 to $25.48. Find the percent change.
Sveta_85 [38]

Answer:

4%

Step-by-step explanation:

The raise in her hourly pay is

$25.48-$24.50 =$0.98

Cross multiplying (rule of three)

24.50------100%

0.98--------x%

and so, x= 0.98*100/24.5 = 4%

A family member has some five dollar bills and one dollar bills in their wallet. Altogether she has 18 bills and a total of $62.
Pepsi [2]
X - the number of five dollar bills
y - the number of one dollar bills

She has 18 bills in total.
x+y=18 \\ y=18-x

She has $62.
5x+y=62 \\&#10;y=62-5x

Set both expressions equal to each other:
18-x=62-5x \\&#10;-x+5x=62-18 \\&#10;4x=44 \\&#10;x=11 \\ \\ y=18-x=18-11=7

She has 11 five dollar bills and 7 one dollar bills.

You have the same bowl, with 5 orange, 6 blue, 3 green, 4 red and 7 yellow candies. You take out an orange candy
xeze [42]
Answer: B) 1/6

Explanation: First, we want to add up all the candies, and after doing that we discover that there are 25 candies in total. Next, we take away an orange candy, leaving us with 4 orange candies, but it also takes away 1 from the number of total candies, leaving us with 24 total candies. Finally, we put orange candies as our numerator and total candies as our denominator and get 4/24, which simplified becomes 1/6.
