Hence, the equation for the question (7) is $n + 19 = 84$ and equation for (8) is $3n = 12$ . It can be solved by linear equation in one variable.

What is a linear equation in one variable?

A linear equation in one variable is written as $ax+b = 0$ . Here, $a$ and $b$ are constants and $x$ is a variable.

(7)

Consider n number of baseball cards does Mike have. Since this is 19 less then the cards Allan have hence, as you add 19 in n then it will give 84.

$n + 19 = 84$

(8)

Consider the speed of Michelle is n. As, it is 3 times less than the speed of the Jamie hence, it you multiply 3 with n then it will give 12.

$3n = 12$

Hence, the equation for the question (7) is $n + 19 = 84$ and equation for (8) is $3n = 12$ .

1) D
(2/9) x=24

2) C
6x4=24
24=w
W=1/4(6)

3) A
67=9n
67=9n-2
9n-2=67

4) D
C+2x+x-3=56
4x=59
X=14.75
Katie payed 14.75

5) 91
Explanation: divide 18 by two and you get 9. When you add six and seven you carry on so those are your numbers. After you add you get your consecutive numbers, 91 and 92. 91 is the smallest so that is your answer

6)-18
Explanation: c+c+2=-34
2c+2-34
2x=-36
X=-18
18 is your answer

7) 17
Explanation: divide 22 is half. This is 11. 11+6=17. 17 is your answer

8)D

9)A
11-3 =x
However that isn’t an option so I would suggest to choose 3

10)D
4(17-n)=64
