Answer:
37
Step-by-step explanation:
To find the side length in the middle is 12. This is because A(12) squared + B(5) squared = C(13) squared.
Now that we know the side length, we can find x. A(35) squared + B(12) squared = C(x) squared.
35*35=1225.
12*12=144.
1225+144=1369
The root of 1369 is 37, so the value of x is 37.
Answer:
B. 10.71 cents
Step-by-step explanation:
Benito's other expenses total ...
$809 +170 +57 = $1036
so his gas expense is ...
$1822 -1036 = $786
Then the per-mile cost is ...
$786/(7340 mi) ≈ $0.10708/mi
Benito's gas cost averaged 10.71¢ per mile.

Answer:
Son's age is 25.
Step-by-step explanation:
Let the Father's age be 2x.
Let the son's age be x.
Five years ago:
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then:
2x - 5/x-5 = 9/4
⇒ 4(2x - 5) = 9(x - 5)
⇒ 8x - 20 = 9x - 45
⇒ -20 + 45 = 9x - 8x
⇒ 25 = x
∴ x = 25
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50 years
The midpoint for this question is (2,1)
