12 x 12 = 144, 144 x 3 and then subtract 5 to get 427
Answer:
B. (2, 7)
Step-by-step explanation:
(1) 5x + 3y = 31
(2) 2x + 3y = 25 Subtract (2) from (1)
3x = 6 Divide each side by 3
x = 2 Substitute in (2)
=====
4 + 3y = 25 Subtract 4 from each side
3y = 21 Divide each side by 3
y = 7
The solution is (2, 7).
=====
<em>Check:
</em>
(1) 5×2 + 3×7 = 31
10 + 21 = 31
31 = 31
(2) 2×2 + 3×7 = 25
4 + 21 = 25
25 = 25
Answer:
11 degrees.
Step-by-step explanation:
-2 + 13 = 11 Good luck man! :)
Answer:
Because the diagonals of a parallelogram bisect each other (its a property of a parallelogram), we know that 2x - 1 = 7 so that means x = 4.
