Answer:
The total cost of 1 belt and 1 tie is $13 and $39 respectively.
Step-by-step explanation:
Given that,
The cost of 4 belts and 5 ties is $247.
Each tie costs 3 times as much as a belt.
Let the cost of a belt is x and that of a tie is y.
ATQ,
4x + 5y = 247 ...(1)
y = 3x ....(2)
Put the value of y from equation (2) in equation (1)
4x + 5(3x) = 247
4x + 15x = 247
19x = 247
x = 13
Put the value in equation (2)
y = 3x
= 3(13)
= 39
So, the total cost of 1 belt and 1 tie is $13 and $39 respectively.
Answer:
6.85 ounces
Step-by-step explanation:
13.7/2people=6.85
When you multiple same numbers with different exponents, the exponents add. Example x^2 * x^3 = x^4
When you divide same number with different exponents, the number subtracts
1. 5^4 * 5^8 = 5^12
2. 11^18/ 11^-4 = 11^22
