Answer:
Step-by-step explanation:
At the self employed store, her monthly expense would be
y = $835
Which would plot as a horizontal line
At the franchise store here expense would be
y = 5x where x is the number of haircuts completed.
This would plot as a straight line of slope 5
The two would intersect when the two y values are equal
5 x = 835
so the same cost per month would occur at y = 835
at the franchise, she would have completed 835/5 = 167 haircuts.
If she plans on doing fewer than 167 haircuts per month, she nets more money at the franchise,
If she completes more than 167 haircuts per month, the self employed store deal keeps more money in her pocket.
Answer:
Step-by-step explanation: and
What’s the question
24 and 42, I got this by multiplying 5 and 2 then doing the same thing to 7 and adding the sums. I used this method to find the perimeter of 10 and 12 as well.
Let x be the volume (liters) of pure (at 100%) acid needed
Let y be the volume (liters) of the other acid (at 10%) needed
The final solution will be:
a) x+ y = 63 liters, AND their respective concentration in acid: is
100% x & 10% :y that will generate 63 liters at 20%
b) x +0.1 y = 63x 0.2 = 12.6
Let's solve this system of 2 equations:
x + y =63
x + 0.1 y = 12.6
Solving it will give you:
x= 7 liters at 100%
y = 56 liters at 10%
You would move over the -2 making the equation look like this 4x>3x+7. Then move the 3x to the other side of the equation making it look like this 1x>7. Thus the answer is x>7.
