There is only one solution because it is a linear equation.
3x - 6 = 22 - x
3x + x = 22 + 6
4x = 28
X = 7
No nodcause it has to me in y=mx+b form. so just sub. 1 from each side
Multiply each term in the equation by 4/1.
9-2y+2y+4=24
Combine like terms
13=24
Because the result is false, it is no solution.
Answer:
#1. 8.27
#2. 36
#3. 22
#4. 7.25
Step-by-step explanation:
#1: 60÷11=5.45 ----> 5.45×16=<u>87.27</u> <This is a non-terminating decimal>
#2: 60÷5= 12 ----> 12×3= <u>36</u>
<u></u>
#3: Games- 35 Won- 14 Lost- 21
In 1 Game Manchester won = 14/35 = 2/5 games in 54 Game Manchester won = 54 x 2/5 games
= 108 / 5
= 21.6
<u>= 22</u>
<u></u>
#4: 6 : 91 ⇒ n : 110
6(110) ⇒ 91(n)
660 ⇒ 91n
660/91 ⇒ n
<u>7.25=n</u>

The language art teacher wants to know the opinion of the ENTIRE school, so it would be fair if the teacher takes a sample from the ENTIRE school population. She can use the stratified sampling method where she can take a proportionate sample from each grade.
Correct answer: All students in each grade
