Answer:

b=1

Step-by-step explanation:

2b+1+2b=3b+2b

4b+1=5b(Simplify both sides of the equation)

4b+1−5b=5b−5b(Subtract 5b from both sides)

−b+1=0

−b+1−1=0−1(Subtract 1 from both sides)

−b=−1

−b

−1

=

−1

−1

(Divide both sides by -1)

b=1

b=1(Works in original equation)

Alex Ar [27]

Answer:

Step-by-step explanation:

We are given that Jenna knits scarves and sells them on Etsy an online market place.

C(x)=4x+20

Where C=Represents the cost in dollars

x=Number of scarves

We have to create a table to show the relationship between the number of scarves x and the cost C

Substitute x=1

C(1)=4(1)+20=$24

Substitute x=2

C(2)=4(2)+20=$28

C(3)=4(3)+20=$32

C(4)=4(4)+20=$36

C(5)=4(5)+20=$40

C(6)=4(6)+20=$44

The cost of Nate's dinner including a 15% tip was $43.70. What was the cost of dinner alone?
Nookie1986 [14]

Answer:

The cost of dinner alone was $37.145

Step-by-step explanation:

15%=0.15----Convert your percentage into a decimal

43.70*0.15=6.555----Multiply the cost of dinner with the decimal

$43.70-$6.555=$37.145----Subtract the last number(6.555) from the total(43.70) to get the cost of dinner alone of $37.145 -This is making you subtract the percentage from the total!

I hope this helped!
