Hope this helps ! :)
Write 2 equations:
a +b = 39
and b = 1/2a + 6
Now replace b in the first equation with the second one:
a + 1/2a + 6 = 39
Combine like terms:
1 1/2a + 6 = 39
Subtract 6 from each side:
1 1/2a = 33
Divide both sides by 1 1/2:
a = 33 / 1 1/2 = 33 / 1.5
a = 22
Now replace a with 22 in the first equation and solve for b:
22 + b = 39
b = 39 -22
b = 17
The two numbers are 17 and 22.
Break the parenthesis and distribute negative if needed but there are no negatives in front so we don’t have to do that. So we get 5b -9 + b + 8 So after combining like terms we get 6b -1
YOUR ANSWER IS 15i radical 6
D - 21 ≥ 53
solve just like normally would using algebra.
add 21 to both sides
d ≥ 74
