The newest phone by Samsung finally came out and costs $499. You were one of the first people in line to buy it so you got a 15% discount and there was a 8.5% tax. What was the total cost of the phone?

Answers

Answer:

$460.20

Step-by-step explanation:

499*15% = 74.85 (total discount price)

499-74.85 = 424.15 (deduct discount from original price)

424.15*8.5% = 36.05275 (total tax from price)

424.15+36.05275 = 460.20275 (add tax to discounted price)

the answer is $460.20

Answer:

[tex]m=3[/tex]

Step-by-step explanation:

[tex]6m+5-3m=7(m-1)[/tex]

Combine like terms

[tex]3m+5=7(m-1)[/tex]

Distribute the 7

[tex]3m+5=7m-7[/tex]

Subtract 3m from each side

[tex]4m-7=5[/tex]

Add 7 to each side

[tex]4m=12[/tex]

Divide by 4

6m+5-3m=7(m-1)
3m+5=7m-7

Step-by-step explanation:

[tex]10+(2 \times 3)^{2} \div 4 \times \bigg (\dfrac{1}{2} \bigg )^{3}=10+6^{2} \div 4 \times \dfrac{1}{8}=10+36 \div 4 \times \dfrac{1}{8}= \\\\ =10+9 \times \dfrac{1}{8}=10+\dfrac{9}{8} =10+1\dfrac{1}{8} =11\dfrac{1}{8} =11.125[/tex]

Answer:

10 + (2 x 3) {2} divided by 4 x (1/2) {3} = 2.375 (2 3/8)

Step-by-step explanation:

2 x 3 is 6 and 6 to the power of 2 is 36, and PEMDAS makes it where you divided 36 by four instead of 46 (10 + 36) divided by 4. 36 divided by 4 = 9. 10 + 9 = 19. Then 1/2 to the third power is 1/8. 19 times 1/8 = 2.375 (2 3/8)

Answer: 1:2

Step-by-step explanation: you have to subtract 80 from 120 to get 40. Then you would have the ratio 40:80. Then when you simplify it would be 1:2.

The visual work:

120-80=40

40:80=1:2

i know u didnt need the explanation and all that but just wanted to show you how i got it- lol

Answer:

Answer down below!

Step-by-step explanation:

If there were 80 blue marbles, but the amount of red marbles isn't stated. First, you need to figure out how many there are. 80 + Number = 120

Number = 40

The ratio is 80:40

Cutting that in half would be 40:20

We're getting closer

20:10

This is starting to get pretty obvious what our answer could be!

If we kept cutting we would get 2:1

Your answer is 2:1!!

Tatiana is buying b number of books and m number of magazines at the book fair. The books cost $4 each and the magazines cost $2 each. Tatiana's total purchase can be shown with this expression: 4b + 2m. Which expression is equivalent to 4b + 2m?

Answers

Answer:

2(2b + m)

Step-by-step explanation:

We can simplify the expression given in the question using factoring:

4b + 2m

(2 x 2)b + (2 x 1)m

2(2b + m)

The equivalent expression is 2(2b + m).

What is meant by an expression?

It is a sentence with a minimum of two numbers or variables and at least one math operation.

Given that b is the number of books and m is the number of magazines.

The cost of a book = $4

The cost of a magazine = $2

The given expression for Tatianan's total purchase is 4b + 2m.

The given expression can be simplified as

4b+2m = 2(2b+m)

Hence, 2(2b+m) is the equivalent expression of 4b+2m.
