20% is 0.20
If 20% of 50 questions are word problems,
Then 0.20 * 50 questions are word problems.
0.20 * 50 = 10
Movies = x
Video Games = y
1st Month = 5x+3y = 26 (1)
2nd Month = 7x+9y = 64 (2)
(1) x 3; 15x+9y = 78 (3)
(3)-(2);
15x+9y-(7x+9y) = 78-64
15x+9y-7x-9y = 14
8x = 14
x = $1.75
Therefore substituting x in (1);
5x1.75+3y = 26
8.75+3y = 26
3y = 26-8.75
y = $5.75
Hope i helped! Please mark Brainliest if you can :)
Your first going to find the area of both rectangles then you subtract the small one from the big one
Answer:
2,320
Step-by-step explanation:
4.2% gets taken every year and there is 10 year,so 4.2% s uqual to 0.042,so just mutiply 4000 by 0.042 which is 168,then times 168 by 10 which brings you to 1680 and 4000 subtracyed by 1680,which equals 2,320
These are not proportional. In order for them to be proportional they need to be constant (sorry if i’m wrong about that) it can’t be proportional because of the extra .25 cents added to it causing it to not run through the origin.
