Set up an equation. 

35 + 5.50x = 145

Now, x is the amount of weeks, so we need to solve for that. 

35 + 5.50x = 145
-35                -35

5.50x = 110 

5.50x/5.50 = 110/5.50 
x = 20

Answer: a) at least 20 weeks

What fraction has a decimal value between 1/2 and 3/4
andreyandreev [35.5K]
To find the decimal value, we must convert 1/2 and 3/4 into decimal.
1/2=0.5
3/4=0.75
Now we just have choose a random decimal in between the decimal.
Let's choose 0.6
Now we have to convert the decimal into a fraction. So we'll multiply the decimal by100.
0.6×100=60
Then we make the 60 into a fractions. 60/100
Then we'll simply the fraction. 60/100÷10=6/10÷2=3/5
There you go. You have your answer.

3b-5+b=27
4b-5=27
add 5
4b=32
divide by 4
b=8
subsitute
b+r=27
8+r=27
subtracct 8
r=19
