An economy package of cups has 880 green cups. If the green cups are 40% of the total package, how many cups are in the package?
1 answer:
Answer: 2200 total cups in the package.
Step-by-step explanation:
Let's use a rule of 3 here.
We have a total package or 100% of the package full of cups. 880 of the cups represent 40% of the total package.
880 - 40%
We need to find the amount of cups (x) that represent 100% of the package
x - 100%
Let's do our chart.
Solve for x

Answer:
x = ±
Step-by-step explanation:
We have been given the quadratic equation;
The first step is to subtract 50 from both sides of the equation;
Multiplying both sides by -1 yields;
The final step is to obtain square roots on both sides;
Therefore, x = ±
Answer:
Option C.
Step-by-step explanation:
Given information: RSTU is a parallelogram, Digonals RT and SU intersect each other at point V, UV=(x-3) and VS=(3x-13).
According to the properties of a parallelogram, the diagonals of a parallelogram bisect each other.
Using the properties of parallelogram we can say that point V divides the diagonal SU in two equal parts, UV and VS.
Subtract x from both sides.
Add 13 on both sides.
Divide both sides by 2.
Therefore, the correct option is C.
