Edwin takes 1 more hour hiking 12 miles than Mayumi because Edwin hikes 12 miles in 9 hours and Mayumi only takes 8 hours.
Answer:
22-14 = j so j = 8
Step-by-step explanation:If j is 14 less that 22 than you need to find 14 less than 22 and that makes the equation 22-14.
Answer:
No
Step-by-step explanation:
When a question asks you if a x value is a possible solution the first thing you should do is try it out!
------
SO let's replace the x in 2X=9 with 1.5
1.5×2= 3
IS 3 equal to 9?
NO it's not so 1.5 is not a possible solution
t = 1.33 sec
Solution:
Given data:
Velocity 
= 17.5 ft/s
Height 
= 5 ft
The height can be modeled by a quadratic equation
where h is the height and t is the time
a = –16, b = 17.5, c = 5
It looks like a quadratic equation. we can solve it by quadratic formula,
Time cannot be in negative. So neglect t = –0.235.
t = 1.33 sec
Hence Amy have to react 1.33 sec before the volleyball hits the ground.
Answer:
The equation is y = -5x + 55
Slope = -5
y-intercept = 55
Step-by-step explanation:
The given table shows the different coordinates of points on a straight line.
The general equation of a line is y = mx + b
where m is the slope and b is the y intercept.
Actually , here only 2 values are needed but there are 4 values given which is just to check whether our line is correct or not.
Substitute values of x and y in the equation.
Put (1,50),
50 = m + b ----------(1)
Put (2,45),
45 = 2m + b -----------(2)
Solve (1) and (2),
Slope , m = -5
y-intercept , b = 55
Hence , the equation is y = -5x + 55.
