Well first it would be 49x3 and that would equal the area so the area is 147. Next you would want to divide that by 4 because there is four sides of the mural, so 147 divided into 4 equals 36.75 square centimeters per side of the mural. The nearest tenth I believe would be 3.675.


So answer: 3.675 but I’m not sure so don’t get mad at me if I’m wrong lol

A student is solving the equation 10x−3+2x=6(x−3). Which describes a first step the student could use to solve the equation corr
Arisa [49]

Students can combine like terms on the left side of the equation, resulting in 12x−3=6(x−3).

Given the equation solved by a student

10x−3+2x=6(x−3)

  • The first step that the student could use to solve the expression correctly is to expand the bracket on the right-hand side of the equation using the distributive law as shown:

10x-3+2x=6(x-3)\\10x-3+2x=6x - 6(3)\\10x-3+2x=6x - 18\\

  • The student can also combine like terms on the left side of the equation, to give;

10x-3+2x=6(x-3). \\10x+2x-3=6(x-3)\\12x-3=6(x-3)

Hence the correct option will be students can combine like terms on the left side of the equation, resulting in 12x−3=6(x−3).

2. A 48-foot rope is cut into three lengths. The second length of rope is twice the first
BigorU [14]

Answer:

48/3.2=15

30

15

3

Got 3.2 from Second length is twice the third so we divide by 2 + 1 = 3

0.2 is from 1/5 = 0.2

3 is the third length

30 is second length and 15 is the first.
