Answer:
y = -29/19 and x = -44/19
Step-by-step explanation:
3x + 2y = -10 multiply by -2 ⇔ -6x - 4y = 20
2x - 5y = 3 multiply by 3 ⇔ <u> 6x - 15y = 9 </u>
Add the two equation -19y = 29
y = -29/19
Use equation one and solve for x
3x + 2(-29/19) = -10
3x - 58/19 = -10
3x = -10 + 58/19
3x = -190/19 + 58/19
3x = (-190 + 58)/19
3x = -132/19
x = - 132/ 19 ÷3
x = -44/19
627 percent of 825 is 5172.75
Answer:
80
Step-by-step explanation:
Plug it in.
So 5 x 2 (4 x 3- 2 x 2)
5x2(12-2x2)
5x2(12-4)
5x2(8)
(10)(8)
So, the answer is 80.
