Answer:

D. The solution is (8, 2).

Step-by-step explanation:

x -  2y = 4

5x -3y = 34       Multiply the first equation by 5:

5x - 10y = 20    Subtract:

0 + 7y = 14

y = 2.

Substitute for y in the first equation:

x - 2*2 = 4

x = 4+4 = 8.

Alex_Xolod [135]
If you're asking how many shirts he needs to sell in a month to start making a profit, the answer is:

35+25
$60+5.80t-10t=0

60-4.2t=0
multiply both sides by 10
600-42t=0
600=42t
divide both sides by 42
t=100/7 which is approximately 14

7. What's the sum of 2/5 and 2/4?
NISA [10]

Step-by-step explanation:

2/5+2/4 (find common denominator)

The common denominator is 20

2/5 is 8/20 (multiply by 4)

2/4 is 10/20 (multiply by 5)

8/20+10/20 is 18/20

If you simplify 18/20 this would by 9/10 if you divide by 2

so the total is 18/20 or 9/10 simplified

Hope this helps!!!!

Have a nice day :)
