what is the value of 6(2b-4) when b+5?

Answers

Answer:

The value of 6(2b-4) is 36.

Step-by-step explanation:

Given expression: 6(2b-4)

To find the value of 6(2b-4) at b=5, we need to substitute the b=5 in the expression, we get

6(2(5)-4)

= 6(10-4)

=6(6)

= 6x6=36

⇒ 6(2(5)-4)=36

Answer:

The value of 6(2b-4) when b=5 is 36.

Step-by-step explanation:

4. Find
A) 64.5
B) 68.5
C) 72.5
D) 76.5

Answers

Answer:

A) 64.5

Step-by-step explanation:

A circle's measurement is 360°.

It is given that arcPQ is 113° and arcQM is 118°. Subtract 113 and 118 from 360:

360 - (113 + 118) = 129°

ArcPM is 129 degrees. Note that this is a inscribed, but not a central angle. m∠PQM = (ArcPM)/2

m∠PQM = (129)/2

m∠PQM = 64.5

A) 64.5 is your answer.

triangle abc is similar to triangle aed

Answers

Answer:

Christina had a total of $120 to spend while shopping. She already spent $68 on clothes . She wants to buy some video games that are on sale for $10 each, including tax.

Answers

Answer:

5 video games.

Step-by-step explanation:

In order to find the total number of video games that Tracy can buy with the money, she has we first need to find how much money she has left after buying the clothes. To do this we subtract the amount she spent on clothes by the initial total that Christina had.

120 - 68 = 52

Now that we know Christina has a remaining $52, we can divide this amount by the value of each individual game ($10) in order to calculate how many she can actually afford.

52 / 10 = 5.2

Finally, we can see that she can afford to only buy 5 video games.
