The formula for simple interest =
I = PRT
P = initial capital = $7000
R = rate = 0.02 in this case
T = time = our variable we are solving for
Thus substitute the parts into the equation we get
280 = 7000*0.02*T
Solving for T we get A or 2 years
1. x= -1/7 y=24/7 (use socratic app, because this is too much work)
2. y = 2
3. y = 1/3 (use socratic app, because this is too much work)
4. x=2, y= -1
2) x-3y= -6
2x-7y=10
x-3y=-6
+3y +3y
2(-6+3y)-7y=10
-12+6y-7y=10
-12-y=10
+12 +12
-y= -22
y= -22
4) 5x-3y= -11
2x-6y= -14
3x+5y=3
x-2y=0
+2y +2y
x=2y (not the answer yet)
3(-2y)+5y=3
-6y+5y=3
-1y=3
-1y/-1 = 3/-1
y= -3
x= 2(-3) = -6
Hello there! To find the percentage of students that voted, all you have to do is divide the number of students that voted by the amount of eligible voters and multiply it by 100. 1,550/2,000 is 0.775. 0.775 * 100 is 77.5. There . 77.5% of students voted. The answer is C: 77.5%.
4×2=8. 100×2=200
8% out of 200
so
4=8 if you have double, 200
