which answer describes the simpler problems that could be used to solve this story problem?

gloria used colored pieces of glass for her artwork. she used 5 pieces of red glass and 4 pieces of yellow glass. she also used 2 times as many green pieces of glass as yellow glass. how many pieces of colored glass did gloria use in her artwork?

a. calculate the number of green pieces of glass.
subtract the number of green pieces of glass from the number of red and yellow pieces of glass.

b. calculate how many more red pieces than yellow pieces of glass.
add that answer to the number of yellow and green pieces of glass.

c. calculate how many more red pieces than yellow pieces of glass. multiply the answer by 2.
add the product to the number of red and yellow pieces of glass.

d. calculate the number of green pieces of glass.
add the number of green pieces of glass to the number of red and yellow pieces of glass.

The answer is D.

Step-by-step explanation:

To find the total of the glass she used you need to find the value of all the glass and add them together.

5 Red, 4 Yellow

2 times as many green as yellow

2 * 4 = 8

8 Green

5 + 4 + 8 = 17 Total pieces of colored glass.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
