<h3>
Answer: 82</h3>
====================================================
Explanation:
Let A be the tens digit and B be the units digit
We can write the number as AB. So if A = 9 and B = 2 for instance, then the number is AB = 92. Keep in mind I'm not multiplying A and B here.
"The unit digit is a prime" means B could be any of these values {2,3,5,7}. We only list the single digit primes. The value 1 is not prime.
Now multiply each of those items by 4
4*2 = 8
4*3 = 12
4*5 = 20
4*7 = 28
Of those results, only 4*2 = 8 leads to a single digit answer.
This must mean that A = 8 and B = 2
Therefore the number is AB = 82.
Answer:
The first table is the only table representing a linear function.
Step-by-step explanation:
<em>" You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference. This table is linear."</em>

2.54(x) = cm in inches
2.54(12) = 30.48
12 inches = 30.48 cm
20.25 because 1 mile takes 0.75 minutes
Answer:
x=3.52 y=66.88
Step-by-step explanation:
x+y=70.4
y=19x ---(1)
using (1)
x+19X=70.4
=> 20x= 70.4
x=3.52
y=66.88
