Step-by-step explanation: well if there is lollipops for $2.50 each and they sold thrice as many lollipops then they have sold 7.5 of the lollipops and if you sell thrice of the cookies then that will be 31.5 and if you add 7.5 and 31.5 that will be 39 so the real answer is 389.

Where v is the final velocity (in m/s), u is the initial velocity (in m/s), a is the acceleration (in m/s²) and s is the distanc

Anna11 [10]

Answer:

The final velocity v is 21.74 m/s.

Step-by-step explanation:

Given:

$\textrm{initial velocity} = u = 9\ m/s\\\textrm{acceleration} = a = 7\ m/s^{2}\\\textrm{distance} = s = 28\ m$

To find:

$\textrm{final velocity} = v = ?$

Solution:

As we know the third equation of motion is represented as

$v^{2} = u^{2} + 2\times a\times s\\$

Substituting the values u, a and s in the above equation we get

$v^{2} = 9^{2} + 2\times 7\times 28\\ =81 + 392\\=473\\$

$v =\±\sqrt{473} \\v =\sqrt{473} \ \textrm{as acceleration is positive v is also positive}\\v = 21.74\ m/s$

Help me with this please everyone

cupoosta [38]

First, let's simplify each expression by combining like terms:

A: 9x-3x-4 = 6x-4

B: 12x-4 = 12x-4 (Already Combined terms)

C: 5x+x-4 = 6x-4

When looking at the list of equations, it is clear that only Expression A and C are equivalent. Brianna failed to combine like terms and plug in more points than 0.

I Hope this Helps!
