Answer:
this
Step-by-step explanation:
the number of boys is 52, if there are 26 girls and boys, and theres 26 more boys than girls then the answer is 52
Answer:
here's what we know:
a + b = 72
a - b = 26
We can use the elimination method to solve this problem:
a + b = 72
a - b = 26
---------------
2a = 98
Divide both sides by 2:
a = 49
So we now have:
49 + b = 72
and:
49 - b = 26
Subtract 49 from both sides:
b = 23
and
-b = -23 (multiply both sides by -1) → b = 23

Answer:
A, B, C, and E
Step-by-step explanation:
y = 4x - 20
8x - 2y = - 20 (divide everything by 2)
4x - y = -10
-y = -4x - 10
y = 4x - 10
4x - 10 = 4x - 20
0 
-10
No solution
10^2 is 10×10 which is 100
4^2 is 4×4 which is 16
so it simplifies to 100-16×2. By Order Of Operations, parentheses, exponents, multiply and divide, add and subtract 100-16×2 makes 100-32 which is 68
