Answer:
-42
Step-by-step explanation:
-2y = 46
y = 46/ -2
y = -23
Substitute y in y = 4x-11
-23 = 4x -11
-23+11 =4x
-12 = 4x
x = -12/4
x = -3
Now plug in x value in 14x
14(-3) = -42
Answer: the answer should be c
Step-by-step explanation: -3x - 13 is easily found by the perimeter of time (y as a representative)

Answer:
56 screws
Step-by-step explanation:
So, first we can find how many screws he needs.
So, if he uses 2 steps for 8 screws, and has 14 steps, that means he puts screws in 7 steps ( 14÷2)
then, if he uses 8 screws, each with 8 steps, we can do 8 times 7, which is 56 screws
20 meter per second= 1200 m/h=1.5km/h
The time is 1300: 1.5 =866.66
