Uhh I wish I could help but I cannot I'm so sorry
Answer:
You would be correct!
Step-by-step explanation:
10 × 4 = 40 40 + 15 = 55 therefore D is the answer great job!
4. 6x + 5y = 4 a
6x-7y = -20 b
a-b
6x + 5y -6x+ 7y = 4+20
12y = 24
y = 2
Sub y in a
6x + 10 = 4
6x = 4-10
x = -6/6 = -1
5. 2x-3y=12 a
4x+ 3y = 24 b
b+a
4x+3y+2x-3y =36
6x=36
x=6
Sub x in a
12-3y = 12
-3y=12-12
y= 0/3 = 0
The answer is 21.
2^3 = 8
21 - 13 = 8
