What is 1/20 divided by 5/8?

Answer:

v = 8

Step-by-step explanation:

• Solve for v -3v+11=-8v+51 Simplify your answer as much as possible.

-3v + 11 = -8v + 51

-3v + 8v = 51 - 11

5v = 40

v = 40 : 5

v = 8

--------------------------

• check

-3(8) + 11 = -8(8) + 51

-24 + 11 = -64 + 51

-13 = -13

The number 143 is a composite number due to having more than two factors.

The factors of the number 143 are 1, 11 and 13.

What is the difference between a prime number and a composite number?

Prime number has only two factors i.e. 1 and the number itself while composite numbers can have more than two factors.

143 = 1*11*13

Since the number 143 has 3 factors i.e. 1, 11, and 13.

So, The number 143 is a composite number.

Therefore, The number 143 is a composite number due to having more than two factors.

Answer:

$18

Step-by-step explanation:

since she saved 20% you turn the percentage into a decimal which is .20 then multiply it by 15 because that's how much she saved and you get $3 which you add to $15 and you get the regular price which is $18

The total of Leiff’s online purchases will be $119.32.Option d is correct.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

If the video game's original price is $128 and the discount is 15%, then Leiff paid (100-15) = 85% of the original price for the item.

Consequently, the video game's price is as follows:

(0.85 x 128) = $108.80.

Leif must contribute an additional 5.3% of the new price, so

(100 + 5.3) = 105.3% of the new price

= (1.053 x 108.8) = $114.57

Including the video game's shipping cost,

114.57 + 4.75 = $119.32

Thus, the total price is $119.32
