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:
Type of angle - Obtuse
Key information - 180° - 82° = 98° (missing angle)
Equation - 
Step-by-step explanation:
Let's solve for the missing angle first! 180° - 82° = 98°. 180 represents the total among the angles so we use 180 degrees.
then use the statement to solve for y and make it equal to 98°
= -12 subtract 12 from both sides
= 86 Now solve for y by dividing 86 ÷ 5
y = 17.2
<span>Answer: All rational equations don’t necessary have a single solution however they do have solutions that can’t fulfill the answer. Any solution where the denominator is equal to zero results in an undefined equation.</span>
Answer:
a = 13
Step-by-step explanation:
Isolate the variables by dividing each side factors that do not contain the variable.
