Answer:

2 ( 24 ) + 2 a = 215

Step-by-step explanation:

Perimeter of the rectangle is 215 feet, the short sides are 24 feet long and we need to work out the long sides (we will call a long side 'a') so,

24 + 24 + a + a = 215

For this case we have to:

Let "a" be the variable that represents the length of the rectangle and let "b" be the variable that represents the width of the rectangle. Then the perimeter is given by:

P = 2a + 2b

We have as data that:

P = 215 \ feet\\b = 24 \ feet

Then, replacing:

215 = 2a + 2 (24)

Answer:

Option B

When Sarah divided a number by 5, the quotient was 247 with a remainder. What is one possible dividend? With a complete sentence
Stolb23 [73]

Answer:

When a number is divided by 5 and the result is 247 with a remainder, one possible dividend is 1236.

The quotient of  a number is the number that is gotten when a number is divided by another number. For example, the quotient of 10 and 2 is 5.

An unknown number was divided by 5 and the result was 247 with a remainder. In order to determine the number the first step is to determine the product of 247 and 5.

247 x 5 = 1235

Since the number has a remainder, the number cannot be exactly 1235. The number would lie between 1235 and 1240. The numbers can be 1236, 1237, 1238 and 1239.

This is for an exam please help IM LITERALLY GIVING YOU ALL OF MY POINTS!!!
Ymorist [56]

Answer:

The equations should have been added up to equal 180 instead of being set to equal each other. The two are supplementary angles, which can be seen due the rule that a pair of interior angles on the same side of the transversal is supplementary. To fix this issue from the work that they did, they should subtract the 140 from 180, so the correct measure of DKH is actually 40 degrees.

Huilan is 15 years younger than Thomas. The sum of their ages is 33 . What is Thomas's age?
Sphinxa [80]

h = t - 15

h + t = 33

Because we have a value of h, we can plug it into the second equation to solve for t.

t - 15 + t = 33

Add 15 to both sides.

t + t = 48

Combine like terms.

2t = 48

Divide both sides by 2.

t = 24

<h3>Thomas's age is 24.</h3>
