Answer:
48 / x = 8
x = ?
Basic multiplication & division but x = 6
6 * 8 = 48
1. 8 * 1 = 8 + 0 = 8
2. 8 * 2 = 8 + 8 = 16
3. 8 * 3 = 8 + 8 + 8 + 24
4. 8 * 4 = 8 + 8 + 8 + 8 + 32
5. 8 * 5 = 8 + 8 + 8 + 8 + 8 = 40
6. 8 * 6 = 8 + 8 + 8 + 8 + 8 + 8 = 48
I'd recommend practicing with some mulitplication flashcards. One of the best things I ever did! :)

Answer:
Step-by-step explanation:
Add the 2 equations
-7x+8x = 13-14
x=-1
7-y=13
-y = 6
y=-6
Given:
4 large oranges @ 0.75 each
8 small oranges @ 0.50 each
total amount paid: 7.49 including sales tax.
4(0.75) = 3.00
8(0.50) = 4.00
3 + 4 = 7
7 + t = 7.49
t = 7.49 - 7
t = 0.49 total amount of tax paid.
0.49/7 = 0.07 sales tax rate
the sales tax rate is 7%
4(0.75) + 8(0.5) = 7
7 x 0.07 = 0.49
7 + 0.49 = 7.49
