Last month, you were able to purchase 8 computers. By the middle of the current month, you were able to purchase 8 more computer

Arada [10]

Answer:

125 %

Step-by-step explanation:

Computers purchased in the last month = 8

By the middle of the current month, 8 more computers than the last month were purchased. This means, total number of computers purchased by middle of current month = 8 + 8 = 16

Number of computers purchased by end of current month = 2

So,

Total computers purchased by current month = 16 + 2 = 18

We have to find the percentage increase in the number of computers from last month's purchases to the end of this month's purchases. The formula for percentage change is:

$\text{Percentage Change}=\frac{\text{New Value - Original Value}}{\text{Original Value}} \times 100\%$

Here, Original Value is the number of computers from last month and New Value is the number of computers from current month. Using the values in the formula, we get:

$\text{Percentage Change}=\frac{18-8}{8} \times 100\% = 125\%$

Thus, there was a 125% increase from last month's purchases to the end of this month's purchases

Solve the given system by the substitution method <br>5x + y 19 <br>7x-2y = 13

lesya692 [45]

Answer:

x = 3 , y = 4

Step-by-step explanation:

5x + y = 19 --------- ( 1 )

=> y = 19 - 5x

7x - 2y = 13 ------------ ( 2 )

Substitute y in ( 2 ) :

7x - 2( 19 - 5x ) = 13

7x - 38 + 10x = 13

17x = 13 + 38

17x = 51

x = 3

Substitute x in ( 1 ) :

5x + y = 19

5( 3 ) + y = 19

15 + y = 19

y = 19 - 15

y = 4

If $y=x+6$ and $y=-2x-3$ , then you can replace $y$ in either equation with the equivalent expression given by the other equation. In this case, you have
