The work of a student to solve a set of equations is shown:Equation A: y = 15 – 2z Equation B: 3y = 3 – 4z Step 1: –3(y) = –3(15 – 2z) [Equation A is multiplied by –3.] 3y = 3 – 4z [Equation B] Step 2: –3y = 15 – 2z [Equation A in Step 1 is simplified.] 3y = 3 – 4z [Equation B] Step 3: 0 = 18 – 6z [Equations in Step 2 are added.] Step 4: 6z = 18 Step 5: z = 3 In which step did the student first make an error
If √6 is the geometric mean between 4 and another number, then the number is
B) 42
C) 186
D) 216
Answers
The total population is 216. so option D is correct.
What is the unitary method?
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Here, 36 is only 1/6 of the population,
then, 36 x 6 = 216
6/6 or one whole of the population which is 216.
Hence, option D is correct.

Answer:
3) x = 9
4) x = 3
Step-by-step explanation:
3) The two short segments are indicated as having a sum equal to the long segment.
(x +2) +(-5 +x) = 15
2x = 18 . . . . . . . . . . . . add 3
x = 9 . . . . . . . . . divide by 2
(This makes the segments be 9+2 = 11 and -5+9 = 4, which total 15.)

4) Same deal.
3x +3 = 4x
3 = x . . . . . . . . subtract 3x
(This makes the segments be 3(3) = 9 and 4(3) = 12, where 9+3=12.)

Answer:
Undefined
Step-by-step explanation:
This is just a vertical line when mapped from the data points given, therefore it has an undefined slope.

l=w+7
perimiter=2l+2w
perimiter=2(l+w)
subsitute
2(w+7+w)=permiter
2w+14+2w=4w+14=permiter
4w+14=110
subtract 14 from both sides
4w=96
divide both sides by 4
w=24
width=24
l=w+7
l=24+7
l=31
legnth=31
width=24
so, the equation is 110=2(l+w)
we know that l is 7 inches greater than w
so, l=w+7
now, substitute that for l
110=2(w+7+w)
110=2(2w+7)
110=4w+14
96=4w
w=24
