Answer:
their average speed was 60 mph
Step-by-step explanation:
1440 divided by 24 because there are 24 hours in a day = 60 so 60 mph
Answer:
1) 16x -4
2) 7x + 45
Step-by-step explanation:
1 ) 6x + 2(5x -2)
we are going to open the bracket
we have,
6x + 10x - 4
16x -4
4(4x - 1).................................................... simplified
number 2
7x + 3(8+7)
7x +24 + 21
7x + 45........................................................... simplified
so therefore the solution to the first and 2nd question is
1) 16x -4
2) 7x + 45
Part A: make slope-intercept form of equation
We will have variable y for the depth of the submarine after x hours. The start 1,500 will be written -1,500 because it's below surface of water.
The equation after x hours will be
y = -1,500 + 52x
y = 52x - 1,500
Part B: Find the depth after two hours
Change variable x with 2
y = 52x - 1,500
y = 52(2) - 1,500
y = 104 - 1,500
y = -1,396
Negative means it's below surface
110 years apart. Just subtract the little number from the big one.
20% of 150 is 30 because you multiply .20 x 150 "of" = x
