Solve the second equation for f(b)
2f(b) = 28
f(b) = 28/2
f(b) = 14
----------
Plug in x = b and solve for b
f(x) = 3x-1
f(b) = 3b-1 ... replace every x with b
14 = 3b-1 ..... plug in f(b) = 14
3b-1 = 14
3b = 14+1
3b = 15
b = 15/3
b = 5
-----------
f(x) = 3x-1
f(2b) = 3(2b)-1 .... replace every x with 2b
f(2b) = 3(2*5)-1 .... plug in b = 5
f(2b) = 3*10-1
f(2b) = 30-1
f(2b) = 29
Sally bought 124 sheets of stickers. Each sheet had 14 stickers. She gave away 204 stickers to her family and friends on Christmas. How many stickers does Sally have remaining?
Answer:
Sally has 1,532 stickers remaining.
Step-by-step explanation:
First, you have to determine the total amount of stickers Sally bought by multiplying the number of sheets she bought for the number of stickers in each sheet:
124*14=1,736
Now, you have to subtract the number of stickers Sally gave away to her family and friends from the total amount of stickers she bought:
1,736-204=1,532
According to this, the answer is that Sally has 1,532 stickers remaining.

Does anybody know what 4/5 ( + 1) is in standard form?
Answer:
4/5 + 1 = 5/5
Step-by-step explanation:
This is because the bottom number is the denominator and the top number is the whole number. So, when you add a whole number to a fraction, the whole number goes to the numerator, not the denominator.
Kiran has 10 1/2 feet of lumber and wants to make a bookshelfKiran needs two side panels that are each 5 2/3 feet. How much more lumber does Kiran need in order to make the side panels?
Total height of lumber, H = 10 1/2 feet = 21/2 feet .
Height of side panel, h = 5 2/3 feet = 17/3 feet .
Now,
Extra lumber required, L = 2 × Height of side panel - Total height of lumber
[tex]L=[2\times (\dfrac{17}{3})]-\dfrac{21}{2}\\\\L = \dfrac{5}{6}\ feet[/tex]
Therefore, extra lumber required is [tex]\dfrac{5}{6}[/tex] feet.
Hence, this is the required solution.
