Answer:
she can hand out 32 cups
Step-by-step explanation:
Answer: 8%
Step-by-step explanation:
3 1/2r=28
3.5r=28
cross of 3.5 and r remains
divide 28 and 3.5
and r=8
r=8
There are a couples of ways to find the solution to the system of equations:
1. If the equations are provided we can use method of substitution or we can use method of elimination to find the solution to the system of equations.
2. Another method to find the solution to the system of equation is by graphing.
Now, when we graph a system of equations, the point of intersection of the two graphs tell us the solution to the system of equations.
Here as we can see that a pair of equations are plotted already and they intersect at point
, where
and
.
Therefore, the solution to the system of equations is
(that is the point of intersection as well).
To answer this, you need to put 115 and 345 into a fraction.
115/345
Reduce it, which results in the fraction 1/3.
Now you have to convert 1/3 to a decimal: .33333
The 3 will continue to repeat. To convert a decimal to a percent you simply need to move the decimal point two places to the right: 33.333
Simplified, your final answer (with a fraction) is 33 1/3%
Or rounded to the nearest tenth of a percent, 33.3%
