It is only 1 proportion, and it is 1 problem.
10 8
---- = ---
X 4
1). It is 8x=40
2). Divide both sides
by 8
3). X=5
3% is the interest rate. Using the formula I=PRT, you can simply derive the rate by putting the given numbers in.
I = 450P = 3,000R = ?T = 5 Years
The equation now goes,450 = 3,000 * R * 5450 = 15,000 * R450/15,000 = R0.03 = R
multiply it by 100,
R = 3%
The complete question in the attached figure
we know that
the total the hours--------------- > 9+10+6+13+5=43 hours
Art hours------------->10
Math hours------------->9
Math and Art hours------> 10+9=19
if 43 hours ------------------> 100%
19 hours----------------------> X
X=19*100/43=44.19%---------- > <span>Approximately 45%

the correct answer is the option B about 45%
Step-by-step explanation:
A line is intersecting Point (3,4) and (-1,-3)
m = (y2 - y1)/(x2 - x1)
m = (-3 - 4/(-1 - 3)
m = -7/-4
m = 7/4
Slope = 7/4
The domain is the x value.
List the x value of where all the dots are:
-6, -4, -2, 1, 4
