Answer:

The equations (6x+42) degrees and (18x-12) degrees are congruent angles so to set up the equation, put both expressions on different sides of the equals sign. Use properties of equality to get x=4.5

Step-by-step explanation:

Your equation should be 6x+42=18x-12

Add the 12 to both sides to get 6x+54=18x

Move the 6x to the other side to get 54=12x

Then divide by 12 on both sides to get 4.5

Therefore, x=4.5.

Please respond to the question below in your own words with proper explanations

ycow [4]

Answer:

$t(400)=673$ .

It means that 673 of 9 inch tiles are required to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.

Step-by-step explanation:

Given:

The function relating number of 9 inch tiles required and area to cover is:

$t(A)=\frac{144}{9.25^2}A$

Now, plug in 400 for $A$ to evaluate $t(400)$ .

$t(400)=\frac{144}{9.25^2}\times 400=\frac{144\times 400}{85.5625}=\frac{57600}{85.5625}=673.19\approx6225$

Therefore, Don required 673 of 9 inch tiles to cover an area of 400 square feet, when spacing the tiles a quarter inch apart.
