weeeeeb [17]

Answer:

x = number of days

y = number of remaining photos saved to her camera roll.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The number of pictures saved in the camera roll (2,500) minus the amount of photos that she deletes per day (50) multiplied by the number of days (x) must be equal to the number of photos remaining.

y =2,500- 50x

The variables are x and y.

Where x is the number of days and y is the number of remaining photos.

M×10+m×13=138<br><br>sorry theres another loll I'm so bad at these
Dimas [21]
So first of all you would add the two together
so it would be m23.

138÷23 would equal 6,

therefore m would equal six

to check it substitute m for 6 and you should get 138!

Thuy wrote the system of equations. 24 x + 36 y = 72. Negative 16 x + 8 y = 80. If the second equation is multiplied by 3, what
Irina-Kira [14]

Answer:

multiply the first equation by 2

Step-by-step explanation:

24x + 36y = 72

-16x + 8y = 80

48x + 72y = 144

-48x + 24y = 240

96y = 384

y = 4

24x + 36(4) = 72

24x + 144 = 72

24x = -72

x = -3

(-3, 4)

How to solve???????????
Soloha48 [4]

Answer:

$70.88

Step-by-step explanation:

To find sales tax, multiply the price by the percentage as a decimal.

$67.50                         67.50(0.05) = $3.38

Since sales tax is 5%, its decimal equivalent is 0.05 and for the price of $67.50 you pay $3.38.

The total amount paid is the price added to the sales tax.

$67.50 + 3.38 = $70.88

Repeat these steps for each price in the sales amount column.
