Answer:
I don't think any options are correct.
Explanation:
When solved for y the process goes as follows:
5x+ 8y = 16
5x + 8y - 5x = 16 - 5x
8y = 16 - 5x
8y/8 = (16-5x)/8
y = 2- (5/8)x
Answer:
Conduct and experiment to rest the trip of different tires
Answer:

Explanation:
Distance can be found by multiplying the speed by the time.

The speed is 25 meters per second. The time is 30 seconds.

Substitute the values into the formula.

Multiply. Note the seconds, or "s" will cancel each other out.


The football player ran 750 meters.
Explanation:
Filtration is the easiest filtering method used in forensic science, and it is commonly used to extract objects from a mixture by either going through a "top filter" that is like a sieve, collecting any solid particles that can be retrieved and inspected for any incriminatory evidence.
They glance to see whether the density of glass objects found on a suspicious matching glass discovered at a scene of the crime. When it does, the evidence indicates that the perpetrator was at the scene.
Answer:


Explanation:
first mass, m1
second mass, m2
initial velocity of m1 is v1.
initial velocity of m2 is zero.
Let the final velocity of m1 is v' and the final velocity of m2 is v''.
Collision is elastic so the coefficient of restitution is 1.
By using the conservation of momentum
m1 x v1 + m2 x 0 = m1 x v + m2 x v''
m1 v1 = m1 v' + m2 v'' .... (1)
by the formula of coefficient of restitution

v1 = v'' - v' .... (2)
So, v' = v'' - v1 put in equation (1)
m1 v1 = m1 x (v'' - v1) + m2 v''
m1 v1 = m1 v'' - m1 v1 + m2 v''
2 m1 v1 = (m1 + m2) v''

so,
