well, Mai is 21 today and when she's 25 is 4 years from now, so
See, please, the offered decision.
To answer this, you need to put 115 and 345 into a fraction.
115/345
Reduce it, which results in the fraction 1/3.
Now you have to convert 1/3 to a decimal: .33333
The 3 will continue to repeat. To convert a decimal to a percent you simply need to move the decimal point two places to the right: 33.333
Simplified, your final answer (with a fraction) is 33 1/3%
Or rounded to the nearest tenth of a percent, 33.3%
Answer:
y= -2/3x + 5
Step-by-step explanation:
Slope-intercept form is y=mx+b
The m is the slope (followed by an x), the b is the y-intercept.
The line intercepts (or crosses) the line x=0 at y=5, so the y-intercept is 5.
The slope can be found with rise over run.
Beginning point is (0,5), end point is (3,3) which equals -2/3
If it doesn't matter whether the points are integers or not you can just pick a number for either y or x and solve for the other variable. For example, if you pick 3 to be your x, plug it in and then solve for y. Start out with:
Plug in 3 for x:
. Then,
. Subtract 21 from both sides and then divide by -3 on both sides. You end up with y=-7 so one of your points is (3, -7)
