Answer:
30 and 6
Explanation:
Let the numbers be x and y. Then
<span>x+y=36</span>
<span>x−y=24</span>
Adding the two equations together gives
<span>2x=60</span>
<span>∴x=30</span>
Substituting this back into either of the equations gives <span>y=<span>6</span></span>
Step-by-step explanation:
First, you divide the numerator and the denominator by 14. (Your fraction is 14 over $2.99.
Once you have that number, you need to simplify.
You get the number 1 over 0.2125 which can be rounded to 0.21. That being said, the unit rate would be be 1 : 0.21.

I think Alexa would be since .3 is a larger number than .03
Let ‘s’ be the son’s age 12 years ago.
Let ‘f’ be the father’s current age.
4 years ago, the son was:
s-4
So, his father is currently:
3(s-4)
=
3s-12
Therefore:
f = 3s-12
In twelve years, the son will be:
s+12
And the father will be:
f+12
This can also be written as:
3s-12+12 as the fathers younger age would be f = 3s+12
=
3s
So, we know that s+12 is half the fathers current age, meaning the father is currently 2(s+12) which is equivalent to 2s+24. Also, we know that the father is currently 3 times the sons age 12 years ago, so 3s (proven by the calculations we made above). Therefore, 2s+24=3s which means 24=s. We can then substitute this, and we will receive 24+12 = 36
Son’s current age: 36
We then substitute the son’s age 12 years ago into 2s+24 to give us the father’s age.
2(24)+24 = 72
Father’s current age: 72
Answer:
80 square feet
Step-by-step explanation:
This time I will get it right for sure!
So first we need to find the area in feet, and then convert it in to inches.
1) Since the patio has the shape of a rectangle, then the formula is:
A = a * b
A = 20 * 16
A = 320 feet
2). Now we have to find the ratio, so:
320 / 4 = 80
So, the answer is
1 square inch to 80 square feet.
