Step-by-step explanation:
just answered your help message
2250= plastic beads
6750= metal beads
STEP 1:
Find total number of beads on clearance
= 2250 + 6750
= 9000 total beads on clearance
STEP 2:
set a ratio; number of plastic beads on clearance to the total number of beads on clearance is what number out of 100
x= percent out of 100
2250/9000= x/100
cross multiply
(9000*x)= (2250*100)
9000x= 225,000
divide both sides by 9000
x= 25%
CHECK:
multiply total number of beads by 25%
= 9000 * 25%
= 9000 * 0.25
= 2250 number of plastic beads
ANSWER: 2250 beads is 25% out of the total number of beads on clearance.
Hope this helps! :)
Answer:
Well, of course, i can not graph it in the coordinate plane in the image, but i can try to teach you how to do it.
We have the function y = (1/2)*x + 5
The first step is to generate pairs (x, y)
You can do it by evaluating the function in different values of x.
For example;
if x = 0
y = (1/2)*0 + 5 = 5
then we have the point (0,5)
if x = 2
y = (1/2)*2 + 5 = 6
Then we have the point (1, 6)
Now, with only two points you can graph the line.
First find the points in the coordinate plane, and mark them.
Now, with a ruler, draw a line that connects the two points.
That line is the graph of the function.
An example of the graph is:
Answer:
3x^2+5x+1
Step-by-step explanation:
(x^2 + 3x + 1) + (2x^2 + 2x)
Combine like terms
x^2 + 2x^2 + 3x +2x +1
3x^2+5x+1
