Answer:
20
Step-by-step explanation:
We have two simultaneous equations.
(1) y = 2x + 50
(2) y = 4.5x
1. Subtract (1) from (2)
0 = 2.5x - 50
2. Add 50 to each side
2.5x = 50
3. Divide each side by 2.5
x = 20

Step-by-step explanation:
Answer:
perimeter = 1 3/4
Step-by-step explanation:
1. 3/4 x 2 because there are two sides with the fraction 3/4. 3/4 x 2 is 1 1/2
2. 1/8 x 2 because there are two sides with the fraction 1/8. 1/8 x 2 is 1/4
3. 1 1/2 + 1/4 = <u>1 3/4</u>
Answer:
6 mile/hour
Explanation :
Let the speed of walking of James = x mile/hour
speed of jogging = 2x mile/hour
9/2x + 1.5/x = 2
= > (9 + 3)/2x = 2
= > 12 = 4x
= > x = 3
Average speed of walking = 3 mile/hour
Average speed of jogging = 2 * 3 = 6 mile/hour
