To solve for this, we need to set up fractional proportions.
We have x% out of 100%, x being what we're looking for and 100 being the total maximum percent.
We have 15 out of 20, being one of our fractions.
Our fractions are:
x/100 = 15/20.
To solve for this, we need to cross multiply the denominator of one fraction by the numerator of the other fraction.
Multiply x and 20, and then 100 and 15.
You should end up with:
20x = 1500.
Divide both sides by 20 to solve for x.
20x/20 = x.
1500/20 = 75.
x = 75.
Your final and absolute answer is :
15 is 75% of 20.
I hope this helps!
r-12
substitute in r=7
so 7-12 = -5
The equation of the line thru <span> (14,5) and (19,15) is found as follows:
15-5 5
slope = m = ----------- = ------ = -1
19-14 5
Thus, the slope of any line perpendicular to this first line has the slope
m = -1/1 = -1.
Then, using the point-slope form, y-15 = -1(x-19), or y -15 = -x + 19, or
y= -x + 34 (answer)</span>
Answer: 6, -6
Step-by-step explanation:
If Ann is at 0, Ben will be four units away from her which could be 4 or -4 so since Carl will be 2 units away from Ben, he the only possible locations are 6, or -6
y-intercept -3
slope 1/2
is sufficient info with which to write an equation for a straight line:
y = mx + b becomes y = (1/2)x - 3.
You should check this by determining whether or not (2,-1) satisfies this equation.
