Good for them ! They worked with things that are related to math
and arithmetic, they had some fun, and they learned something.
Much better than just fishing for answers on some boring website.

Which of the following is equivalent to log168?

Sladkaya [172]

I'm assuming that you meant to add an attachment

but log168 is equal to 2.22530928173

so simply solve the presumed answer choices

The one that equals 2.22530928173 is equivalent to log168

The solution for the following system of equations is shown on the graph. What is the solution?

Bingel [31]

The solution is (3 , 4) ⇒ 2nd answer

Step-by-step explanation:

The system of equations can be solved by:

Elimination method
Substitution method

The system of equations is:

y = 3 x - 5 ⇒ (1)

y = $\frac{1}{3}$ x + 3 ⇒ (2)

By using the substitution method substitute y in equation (2) by equation (1)

3 x - 5 = $\frac{1}{3}$ x + 3

Subtract $\frac{1}{3}$ x from both sides

$\frac{8}{3}$ x = 8

Divide both sides by $\frac{8}{3}$

x = 3

substitute x by 3 in equation (1)

y = 3(3) - 5

y = 9 - 5

y = 4

The solution is (3 , 4)

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 4 h, and Car B traveled the dista

poizon [28]

The rate of Car A is x
The rate of Car B is x - 5

They travel the same distance. So we can make an equation:

4(x) = 4.5(x-5)

Solve for x.

4(x) = 4.5(x-5)
4x = 4.5x - 22.5

Subtract 4.5x on both sides

-0.5x = -22.5

Divide by -0.5 on both sides
x = 45

But we want the speed of Car B which is x - 5

So Car B's speed is 45 - 5 = 40

Your answer is 40
