Answer:

9. C. 35 + 0.12x = 44.36

10. C. The system has no solution since the second equation is equal to 0

11. A. 32

Step-by-step explanation:

9. The Hill family drove for 78 miles

The rental agency chargers a weekend fee of $35.00 and 12 cents per mile

Convert cents to dollars

1 cent = 0.01 dollar  

∴, 12 cent = 12 x 0.01 = 0.12 dollar

Therefore,  total bill amount = 35 + 0.12 per mile

Let "x" be the number of miles driven

Final bill was $ 44.36

44.36 = 35 + 0.12x  

0.12x = 44.36 - 35  

0.12x = 9.36

Divide both sides of the equation by 0.12

x = 78

10. The system of equations is...

The true statement about the given system of equations.  

The slope-intercept form of a line is...

Where m is the slope and b is the y-intercept.

We have,...  

On comparing these two lines with slope-intercept form, we get...  

Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.

11. This is an equation Solutions: x=32.

⇒ Value of (Dimes + Quarters) = $ 6.70  

or, (0.1 m) +  11.5 - 0.25 m  = 6.70  

-0.15 m = - 4.8  

or, m = 4.8/0.15  =  32  

m = 32
