Answer:
there is just dots. cant join anything.
7,030.3 I think... the way you typed it was kinda confusing though, 3 tenths? as in .3? if so, this is your answer
-3(b-4) = -2b
-3b + 12 = -2b
-3b + 3b + 12 = -2b + 3b
12 = b
Okay so.
We have two basic equations
Tower A+ B+720 A is 720ft taller than B.
Tower A+B= 1982 Combined height is 1982ft
Replace A with B+720 in 2nd equation and solve for B
B+720+B=1982 Combine like terms
2B+720=1982 Subtract 720 from both sides
2B=1262 Divide both sides by 2
B=1262/2
B= 631ft
We know that A=B+720 so you simply need to do that addition to have the height of both towers.
Answer:
32.13
Step-by-step explanation:
10% of 42=4.2
Mate gets 4.2
42-4.2=37.8
15% of 37.8=5.67
Mom gets 5.67
37.8-5.67=32.13
32.13
