Answer:
8
Step-by-step explanation:
Answer:
The answer is a= 15
Step-by-step explanation:
First, you multiply both sides by 5. 5*3 = 15 and a/5*5 = a, since 5 and 5 cancels out each other. This is optional, then you flip the equation to get a= 15. Hope this helps.
<h3><u>The value of x, the first number, is equal to 3.</u></h3><h3><u>The value of y, the second number, is equal to 7.</u></h3>
x + 3y = 24
5x + 3y = 36
We can subtract both equations from each-other to cancel out a variable.
After doing so, we're left with:
-4x = -12
Multiply each term by -1
4x = 12
Divide both sides by 4.
x = 3
Now that we have a value for x, we can solve for y.
Plug this value into the first equation.
3 + 3y = 24
Subtract 3 from both sides.
3y = 21
Divide both sides by 3.
y = 7
Answer:
Step-by-step explanation:
From smallest to largest:
I assume you are looking for the formula, and the velocity.
The formula:
v1^2-v0^2=2aS
where
v0=initial velocity (0 if object falls from rest), ft/s
v1=velocity reached after falling a distance S, ft/s
S=distance from initial position, positive downwards (for falling objects), ft
a=acceleration due to gravity, 32.2 ft/s^2 in imperial units
So substituting numbers, assuming initial velocity is zero (from rest), then
S=25 ft
v1^2-0^2=2*32.2*25
v1^2=1610
v1=sqrt(1610)
=40.1 ft/s
