An expression becomes an equation by adding an equal sign to the end of the expression and if there's a number on the other side of the equation. For example, 4+3 becomes an equation if you put 4+3=7. Or, 4+3=2+5. Good luck!
Y-5=9(x-1)
y-5=9x-9

Answer:
Yes, 30.8 is the value of x. I also double-checked by plugging 30.8 into the right side as well.
14/10 = 1.4
30.8/22 = 1.4.
Therefore, because both sides equal 1.4 when you solve with 30.8 plugged in, it must be correct.

Step-by-step explanation:
what you know:
cars = 5
buses = 3x
equation:
158 = 5 + 3x
subtract 5 from both sides
153 = 3x
divide by 3
x = 51
Answer: 62.13%
Step-by-step explanation:
Given , Salary of Mr. Palahniuk = $1190
Percentage of Salary he spent on groceries = 24%=0.24
Amount he deposited in his saving funds = $165
Amount he spent on groceries = (Percentage of Salary he spent on groceries) x (Salary )
= (0.24) (1190)
= $ 285.6
Now , Money left = (Salary) - [(Amount he deposited in his saving funds)+(Amount he spent on groceries)]
= $1190-[$285.6+$165]
= $1190 - $450.6
=$739.4
Percentage of his salary is left = (Money left )÷ (Salary) x 100
= (739.4) ÷(1190) x 100
≈62.13%
Hence, the percentage of his salary is left = 62.13%
