I don't understand this problem...<br> 1/4 x (-12)=

Nikitich [7]

Answer:

-3

Step-by-step explanation:

When multiplying a positive number with a negative number, the product will <u>always</u> be negative. First, let's solve the problem disregarding the negative sign.

$\frac{1}{4} * 12$
$\frac{12}{4}$
$3$

Now that we know the product of 1/4 x 12 is 3, we can assume that the product of 1/4 x -12 is -3.

A tire dealer sells all-season tires for $68 each and all-terrain tires for $125 each. In one day, the sales both tires totaled

Anettt [7]

Start by making variables to represent each tire
S=all-season tires
T=all-terrain tires
Create equations based on what was given in the question
68s+125t=3926 (the price for each tire multiplied by the number of tires equals the overall sales price)
T=14 (14 all-terrain tires were sold)
Sub 14 into the first equation for t in order to solve for s
68s+125(14)=3926
68s+1750=3926
68s=3926-1750
68s=2176
S=32
I hope this helps!
