Answer:
its d
Step-by-step explanation:
the slope is -20 because for every 30 seconds the altitude gets smaller by 600 feet. 600/30=20 so its going down 20 feet per second.
2y+4=6
First, subtract the 4 from both sides:
2y+4-4=6-4
Simplify:
2y=2
Divide both sides by 2:
y=1
5) i dont know
6) (6x-5)(3x-4)
Answer: (2*3) = 6
(2*9) = 18 6+ 18 = 24
(3+9) = 12
Step-by-step explanation:
So whats missing is times 2 on the right side next to (3+9) *2
(2×3)+(2×9)=. (3+9)*2
2.5 ft times 18 balloons equals to 45 ft of ribbon
