First, you would have to change 4 1/2 to a improper fraction, by multiplying the whole by the denominator which is 8, the you add that to the numerator which is one giving you nine. The denominator stays the same but the numerator would now be nine. Then you would have to kfc our new equation 9/2 / 3/4. K means you keep the first improper fraction so it stays as 9/2. F equals flip so you would have to flip the numerator and the denominator of the second improper fraction making it now 4/3. Then lastly, c equals change meaning you would have to change the operation of dividing to multiplying making the new equation 9/2 * 4/3 = 36/6 = 6. I hope my explanation helped.
The constraints placed on the variables y and x in this problem are y≤8 and x≥6.
Answer: they are parallel so there is no solution.
Step-by-step explanation:
Brayden- y=5x-1 or y-5x= -1
Howard- y=5x+1 or y-5x= 1
Vincent- y=4x+5 or y-4x= 5
In summary, they are all parallel so there is no solution. or
5y - 1 = 5y + 1
(Braydon = Howard)
Hope this helps you :) pls BRAINLEST
Answer:
a. x = 7c
b. $28
Step-by-step explanation:
Her allowance starts at $20.
Out of 5 chores, for each chore she completes, she receives $3.
For each chore that she does not complete, she loses $4.
a. An expression describing her allowance
Let her total allowance be x:
x = 20 + (3 * c) + (-4 * (5 - c))
x = 20 + 3c - 20 + 4c
x = 20 - 20 + 7c
x = 7c
b. If she completes 4 chores, she will receive:
x = 7 * 4 = $28
