last month, dory biked 11 times as many miles as karly. together they biked a total of 156 miles. how many miles did dory bike last month?

Answers

Answer 1

Answer: \
Hi there

Let x be the number of miles Karly biked
Dory biked 11 times as many miles as Karly, therefor, Dory = 11x
The total number of miles back by both is 156
The equation will be:
11x + x = 156
Before we can get the number of miles Dory biked, we must first get the number of miles
Karly biked represented by x.
Get the x
12x = 156
12x/12 = 156/12
x = 13
Karly = x = 13 miles biked
Dory = 11x = 11(13) = 143 miles biked
to check:
11x + x = 156
11(13) + 13 = 156
143 + 13 = 156
156 = 156
i hope it helps have a nice day:)

Answer 2

Answer: 11 times 156 which it would be 1,706

By what number should we multiply -15/28, so that the product may be -5/7?

Answers

Answer:

4/3

Step-by-step explanation:

First, multiply -15/28 with 4/3.

Second, you need to cross 28 with 7 and 15 with 3.

$( - 15)/(28) x (4)/(3) = ( - 5)/(7)$

Since 28 divided by 4 is 7, and 15 divided by 3 is 5, therefore this gives the result of 5/7 (with negative sign).

Hope it helps. Thanks!

A TV goes on sale with a discount of 28%. The original price of the TV is $942. What is the sales price of the TV?

Answers

Answer:

28% discount of the TV = $678.24

Step-by-step explanation:

28% discount of the TV = actual price - 28% of the actual price.

Since we know the actual price to be $942

Actual price = $942

28% of the actual price = 28% * actual price.

= 28/100 x 942

= 26376/100

= 263.76.

28% discount of the TV = actual price - 28% of the actual price.

28% discount of the TV = $942 - $263.76

28% discount of the TV = $678.24

A percentage is equivalent to a fraction, a percentage is out of 100 therefore the fraction for this can be 28/100, as a decimal this would be .28. Therefore to solve this problem you would set up the problem as, 942 x .28= 263.76, you then take that number and subtract it from the original price of the tv, and you get the final price, of $678.24.
