Answer:
10$ for an adult and 7$ for a child
Step-by-step explanation:
price for an adult = a
price for a child = b
2a + 4b = 48.............(i)
5a + 2b = 64.............(ii)
make a subject of the formula in equation (i)
2a = 48 - 4b
divide through by 2
a = 24 - 2b
Insert the value of a in equation (ii)
5(24 - 2b) + 2b = 64
120 - 10b + 2b = 64
collect like terms
- 8b = 64 - 120
-8b = -56
divide both sides by -8
b = 7
insert the value of b in equation(i)
2a + 4(7) = 48
2a + 28 = 48
2a = 48 - 28
2a = 20
divide both sides by 2
a = 10
The price for one adult is $10 while the price for one child is $7

hope that helped :)
B, because if you divide 7 by 9, you get 0.7 repeated, which if rounded is 0.78

Answer:
Laura's monthly payment will be $501, and her total finance charge over the course of the loan will be $5,060.
Step-by-step explanation:
Given that in a 5-year loan with an annual interest of 7.5%, the monthly payments for every $ 1,000 are $ 20.04, taking into account that Laura took a loan of $ 25,000, to determine the monthly payments and the total interest to be paid, they must be made the following calculations:
20.04 x 25 = X
501 = X
Thus, the monthly payments that Laura will have to make will be $ 501.
(501 x 12 x 5) - 25,000 = X
30,060 - 25,000 = X
5,060 = X
In turn, the total finance charge will be $ 5,060.
Answer:
50 feet
Step-by-step explanation:
Use the Pythagorean Theorem to find the diagonal (or the hypotenuse)
30²+40²=x²
900+1600=x²
√2500=√x
x=50 feet
