1. -18 +15x = 3(4x-6) + 3x

-18 + 15x = 12x - 18 + 3x

-18 + 3x = -18 + 3x

3x = 3x

x = All Real Numbers (because we don't know what x is since the equation is 3x = 3x, we can assume that it is all "real" numbers)

2. -10 + 5x = 5(x - 3) + 5

-10 + 5x = 5x - 15 + 5

-10 = -10

Answer Undefined (because the x coefficients canceled out, we don't know what x even is, so we can claim it as undefined.)

A classroom has a length of 30 ft. and a width of 20 ft. The flooring is to be replaced by tiles. If each tile has a length of 3
Mashcka [7]

Answer:

100

Step-by-step explanation:

Hello! to calculate the number of tiles needed for the floor you need two things

1. number of tiles that fit across the width, this is achieved by dividing the total width by the width of each tile

Width=20ft=240in

N1=\frac{240}{24} =10

2.number of tiles that fit in the logitude, this is achieved by dividing the total length by the length of each tile.

leght=30ft=360in

N2=\frac{360}{36} =10

Finally, you multiply the number of tiles that fit in width by the number of tiles that fit in length.

N=10X10=100

2. Aarav has 3,250 followers on social media. His number of followers is increasing
maw [93]

Answer:

Option d.

Step-by-step explanation:

It is given that Aarav has 3,250 followers on social media. His number of followers is increasing at a rate of 3% per week.

Initial followers = 3,250

Rate = 3\% =\dfrac{3}{100}=0.03

The exponential growth function is

f(w)=a(1+r)^w

where, a is initial value, r is rate and w is time per week.

Substitute a=3,250 and r=0.03.

f(w)=3,250(1+0.03)^w

f(w)=3,250(1.03)^w

Therefore, the correct option is d.
