A store is selling a pair of sneakers for $80. However, they are having a sale that everything is 15% off. What is the new price of these sneakers after the sale.

Answers

The new price after the sales is $68

Step-by-step explanation:

The cost of a pair of sneakers = $80

Discount / sales offer= 15% off

New price = $80- 15% of $80

15% of $80 = 15 x 80/100

= $12

New price = 80 - 12

= $68

The new price after the sales is $68

-58 + x = -92

Paulo has 39 patches from states he and his relatives have visited he wants to pin the onto a board and arrange them equally in 3 rows how many patches will be in each row

Answers

Given:

Total number of patches = 39

Total number of rows = 3

To find:

The number of patches in each row.

Solution:

We have,

Total number of patches = 39

Total number of rows = 3

We need to divide the total number of patches by total number of rows to find the number of patches in each row.

\text{Number of patches in each row}=(39)/(3)

\text{Number of patches in each row}=13

Therefore, the number of patches in each row is 13.

5(y-4)=7(2y+1) find the y

Answers

Hi Brainiac

Distribute

(5)(y)+(5)(-4)=(7)(2y)+(7)(1)

5y-20=14y+7

Now we need to subtract 14y from both sides

5y-20-14y=14y+7-14y

-9y-20=7

Now add 20

-9y-20+20=7+20

-9y=27

Divide both sides by -9 to both sides so we can find the value for y

-9y/-9= 27/-9

y= -3

If the two lines 2x + y= 0 and y=3 are plotted on a typical xy coordinate grid, at which point will they intersect?Can someone point me in the direction of a vidoe to show how this is done

Answers

we have
equation 1   2x+y=0

equation 2  y=3

substitute the equation 2 in equation 1
2x+[3]=0 \n 2x=-3 \n x=- (3)/(2)

the solution is the point
(- (3)/(2) ,3)

using a graph tool
see the attached figure
2x + y = 0
2x + 3 = 0
      - 3  - 3
      2x = -3
       2      2
         x = -1¹/₂
(x, y) = (-1¹/₂, 3)
