The answer is 52% because there is a total of 25 marbles and if you add the red and blue marbles you get 14 which is more than the green mables which is more than half the amount of the total marbles
Answer:
235=30x-25
Step-by-step explanation:
235+25=30x-25+25
260=30x
260/30=30x/30
x=8.66 or 9 weeks
Answer
Yes its true
truth:
You do get receipts from video stores.
unless thats only my location
ratio of perimeter is the same as ratio of sides so perimeter would be 1:4
since area is in square units you need to square the ratio (1:4)^2 which is 1:16
To answer this, set up a system of equations. What we know is that
5x + 2y = 100
And...
x+y=38
x represents the unknown number of 5 points questions
y represents the unknown number of 2 point questions
In my opinion the easiest way to solve this is to use substitution (that is when you find out the value of one variable, either x or y, and substitute that value as the variable).
So,
x+y=38
Subtract x from both sides
y=38-x
Now, plug (38-x) in as y in the other equation.
5x + 2(38-x) = 100
5x + 76-2x= 100
3x+76=100
3x=24
x=8
Now that you know that x=8, you can solve for y.
5x+2y=100
5(8)+2y=100
40+2y=100
2y=60
---- ------
2 2
y=30
X=8
Y=30
There are 8 five point questions on the test and 30 two point questions on the test
