Answer:

x=8

Step-by-step explanation:

4x+10 = 2x+26

4x-2x+10=2x-2x+26  [Subtract 2x from both sides]

2x+10=26

2x + 10 - 10 = 26 - 10  [Subtract 10 from both sides]

2x = 1

2x/2 = 16/2  [Divide both sides by 2]

x = 8

CHECK:

Does 4x+10 = 2x+26 when x is 8?

4(8)+10 = 2*(8)+26  ?

32+10 = 16+26    ?

42 = 42   <u>YES</u>

Answer:

\large \boxed{\sf x =8}

Explanation:

\sf \rightarrow 4x + 10 = 2x + 26

collect like terms

\sf \rightarrow 4x -2x  =   26-10

subtract like terms

\sf \rightarrow 2x  =   16

divide both sides by 2

\sf \rightarrow x  =   8

Answer:

The total payment is thus $35.75 plus $7.11, or $42.86

Step-by-step explanation:

Note that the sales tax doesn't affect the tip.  The sales tax is 5% of the cost and the tip is 15% of the before tax cost.  We calculate the tax and the tip separately, then add them together and finally add this sum to the cost.

Sales tax:  5% of $35.75:  $1.75

Tip:  15% of $35.75:  $5.36

Adding these two quantities results in $7.11.

The total payment is thus $35.75 plus $7.11, or $42.86

There are 3,250 buttons. If they are divided into groups of 8, how many buttons are there. Interpret the remainder. Show your wo
Andre45 [30]
I am going to assume that the question is asking how many buttons are in each of the 8 groups.

To find out how many buttons are in each of the 8 groups, we simply need to divide the amount of groups by the total amount of buttons.

3250 / 8 = 406.25

That is unlikely the answer, since buttons are hard to divide into quarters.

**************

This is the more likely solution. There are 8 groups of buttons, with 3250 buttons in each group. To find the total amount of buttons, we just need to multiply the number of groups of buttons there are by the amount of buttons there are in each group.

8 * 3250 = 26000

There are 26,000 buttons total.
Hope that helped =)
