Answer:

True.

Step-by-step explanation:

To find out if the statement is true, just plug in 8 each time you see x.

3(8)+ 4 = 28

5(8) - 12 = 28

This proves the statement is true, x = 8.

I hope this helps. If you have any more questions, please feel free to post them and someone will be able to help you, whether it's myself or others. Please leave a like, rating, and if possible, Brainliest. Have a great day!

Jared is redoing his bathroom floor with tiles measuring 6 in. by 14 in. The floor has an area of 8,900 in. What is the least nu
Bond [772]
Firstly we need to find an area of a single tile:

6 * 14 = 84 square inches

Now we just need to find out how many tiles of 84 square inches will fit in an area of 8900 square inches:

8900 ÷ 84 = 105,952380952381

Assuming we can't cut a tile into pieces, we may round the result to 106.

Answer: The least number of tiles Jared will need is <u>106</u>.

What is the slope of the graph of 14x + 7y = –9?
Vera_Pavlovna [14]
We will put ur equation in y = mx + b form, and the slope will be in the m position.

14x + 7y = -9
7y = -14x - 9
y = (-14/7)x - 9/7
y = -2x - 9/7

y = mx + b
y = -2x + (-9/7)....as u can see, the -2 is in the m position and is therefore the slope.

Roger owns a one-acre piece of land. The length of the land is 484 feet. What is the width of his property?
shepuryov [24]

Answer:

W = 90 ft

Step-by-step explanation:

1 acre = 43,560 ft^2

A (area) = L (length) x W (width),

L = 484

A = 43560

W = A/L

= 43560/484

= 90 ft
