T = 44
j = 50
t - j = 6ft/sec
120ft ÷ 6ft/sec = 20s
(44 * 20) + 120 = 880 + 120 = 1,000 ...
50 * 20 = 1,000 ...
Ans = 20 secs...//

14/35 and 15/35
Step-by-step explanation:
Answer:
h = 6
Step-by-step explanation:
Given the 2 equations
- 3x + 4y = - 30 → (1)
9x + 5y = 39 → (2)
We require the value of the x- coordinate at the point of intersection, thus require to eliminate the y- term from the equations
Multiply (1) by 5 and (2) by - 4
- 15x + 20y = - 150 → (3)
- 36x - 20y = - 156 → (4)
Add (3) and (4) term by term thus eliminating y
- 51x = - 306 ( divide both sides by - 51 )
x = h = 6
