The solution is, 14 tiles does Joe need.
Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
given that,
Joe's bathroom floor is 5 feet wide and 8 feet long. He will cover the floor with 3" square tiles.
so first find area
area=legnth times width
5=width
8=legnth
5 times 8=40
so, we have,
area=40
3 area times x number of tiles=40
divide both sides by 3
x=40/3
x=13 and 1/3
since you can't buy 1/3 tiile
round up
x=14
answer is 14 tiles does Joe need.

Step-by-step explanation:
The equation for the given phrase is 6x-9=-15 and the solution for the obtained equation is -1.
The given phrase is "nine less than six times a number is -15."
Let the unknown number be x.
Here, six times a number = 6x
The product is less than 9, that is
6x-9
Nine less than six times a number is -15, so the equation is
6x-9=-15
Now, the solution is
6x=-15+9
6x=-6
x=-6/6
x=-1
Therefore, the equation for the given phrase is 6x-9=-15 and the solution for the obtained equation is -1.

Hello!
6 - 9 × y = -15
When "less than" is used you switch the number before it the number after it. While it seems like it would be 9 -6, its actually 6-9
6 - 9 is -3, you can multiply 3 by 5, to get 15. So your answer would be 5

Answer:
see below
Step-by-step explanation:
y = x+.6
Solve for x
Subtract .6 from each side
y-.6 = x+.6 -.6
y-.6 =x
Let y = 3 y-.6 = 3-.6 = 2.4 =x x=2.4
Let y=4.2 y-.6 = 4.2 - .6 = 3.6 =x x=3.6
Let y =2 y-.6 = 2-.6 =1.4 =x x=1.4
