Answer:

1. AE= 312

2. AC = 161

Step-by-step explanation:

Hey there!

In order to solve the first question, we need to think of possible "C" values

Then after finding the "C" value, we can then find the "A" and "E" values

So:

AC = 24 and CE = 13

What factors do 24 and 13 have in common?

Well, only 1 since 13 is a prime number]

So this means that C has to be 1

Now we know that A is 24 and E is 13

Now we have to multiply them together

24 x 13 is 312

So AE= 312

Now we go on to the second question

We can use the same strategy we used for number one

Instead of finding what C is, we need to find out what E is, since there is E in both of the statements

So:

CE = 7 and AE = 23

What common factors do these two numbers have?

Again, only 1, meaning that E can only be 1

Now we know that C is 7 and A is 23

Since we know this, we can multiply these two numbers together and get our final answer: 161

So AC = 161

What is 2.11 as a mixed number in simplest form
LUCKY_DIMON [66]
<span>2 11/100 you cannot simplify that anymore</span>The first, decimal place is the tenths place and the second is the hundredths place. Since the decimal goes out to two decimal places, the fraction must be over one hundred. To find the numerator, simply look at the value of the decimal, in this case, 11.



<span>That is your final answer, since 11 and 100 have no common factors besides 1, as 11 is a prime number.

A rectangular house has a perimeter of 240 feet. The length of the house is 80 feet. What is the width of the house in feet?
fgiga [73]

The perimeter of a rectangle is 2 times the length and 2 times the width. Since you got the perimeter (240), you can multiply 2 by the length (160) and subtract the perimeter (240) by it, giving you 80. This is 2 times the width. Divide that by 2 (divide 80 by 2) and you will get 40. The width is 40 feet.
