Ad libitum [116K]

Answer:

First question the answer is the third one, 4*4*4*4*4

Second: Part A

I think one side is 25 yards, so answer is 25². that makes the area of the chicken pen  to be 625 sqaure yards.

Part B a yard is exactly three feet, so the power becomes 75², and the area is 5625 square feet.

third question: not sure what the only use once is, but 2^4 and 4² could be the first one, they both equal 16. The second could be 3^4 and 9^2, which are both 81.

A value 5 times a smaller number is 1 less than a larger number. their difference is 73
salantis [7]

Answer:

The numbers are 18 and 91

Step-by-step explanation:

You can translate the information to two equations:

<em>a value 5 times a smaller number is 1 less than a larger number</em>

5a = b - 1

<em>their difference is 73</em>

b - a = 73

Then you should merge one equation into the other, thereby eliminating one variable. You can do this any way you want. I choose to rewrite the first equation as:

b = 5a + 1

Now I can write 5a+1 in the second equation at the place where b was:

5a + 1 - a = 73

It is now an equation with only one variable, solve by simplifying

4a = 72

a = 18

Now b can be found using b = 5a + 1

b = 91
