Y=4x+7
So 4 is the rate of change because if you solve for y, x is the rate of change
Answer:
N(4.49m + 5p )
Step-by-step explanation:
N is the number of jars of fruit salad
Example 3 fruit salads:
3(4.49m + 5p )
Answer:
5.3
Step-by-step explanation:
Stare at the triangle for a bit. And try to add another one sharing the unmarked angle. You end up with an equilateral triangle. It means
is half the hypotenuse, At this point,
Answer:
Joy must use 80 milliliters of solution at 20% and 20 milliliters of solution at 60%
Step-by-step explanation:
Let
x -----> milliliters of solution at 20%
y -----> milliliters of solution at 60%
we know that
----> equation A



so


----> equation B
Solve the system of equations by graphing
Remember that the solution of the system is the intersection point both graphs
The solution is the point (80,20)
see the attached figure
therefore
Joy must use 80 milliliters of solution at 20% and 20 milliliters of solution at 60%
To solve this problem, the first thing you should keep in mind is the following conversion:
1 foot = 12 inches.
Therefore doing the conversion:
(12 inch) * (1 foot / 12 inch) = 1 foot.
The number of sections is:
N = (9 feet) / (1 foot) = 9
Answer:
you can get out 9, 12 inch sections of 9 foot calculator
