Answer: 225
Step-by-step explanation:
225x0.04 is 9
B is the answer I need the points
Answer =6
Step-by-step explanation:
Step-by-step explanation:
Distance = (Rate)(Time) So, Time = (Distance)/(Rate)
Time at slower speed = Time at faster speed + 3
36/x = 36/(x+6) + 3
Multiply the equation by the LCD, x(x+6) to obtain:
36(x+6) = 36x + 3x(x+6)
36x + 216 = 36x + 3x2 + 18x
3x2 + 18x - 216 = 0
x2 + 6x - 72 = 0
(x + 12)(x - 6) = 0
x = -12 or x = 6
Since x can't be negative, x = 6 mph
Answer: c=35
D=90
E=55
Step-by-step explanation:
Since d is a right angle it is 90. Take 90 and subtract it from 180 to get 90.Set them equal to 90 so 3x+11+5x+15=90
Simplify
8x+26=90
8x=64
X=8
Now take x and plug it in for each equation
3(8)+11=35
5(8)+15=55
So measured of c is 35
Measure of e is 55
And d is 90
hope this helps
