Since this is a proportion we cross multiply.
b+2/b-1=4/5
b-1(4)=b+2(5)
4b-4=5b+10
+4 = +4
4b=5b+14
-5b=-5b
-1b=14
divide by -1 on both sides
b=-14
If u take out 30 from the 194 u get 164 every two weeks that mean u make 328 a month and if u save yr check and u get paid 26 times you'll save 8,528

the answer is 77
for every 42 there is 18
42:18 simplify
7:3
7+3=10
110/110=11
7 times 11

Answer:
37.7 mi²/h
Step-by-step explanation:
The area formula is ...
A = πr²
Differentiating with respect to time gives ...
dA/dt = 2πr·dr/dt
Filling in the given values, we have ...
dA/dt = 2π(3 mi)(2 mi/h) = 12π mi²/h
The area is increasing at the rate of about 37.7 mi² per hour.
