<span><span>1.
</span>Given numbers:
74 % of 315
89% of 195
now, let’s solve the first given numbers:
=> 74% of 315
=> 315 is the 100%
Let’s convert 74% into decimals
=> 74% = .74
=> 315 * .74 = 233.1, the value of 74% of 315
Let’s solve the second given:
=> 89% of 195
where 195 is the 100%
=> 89% = .89
=> 195 * .89
=> 173.55, the value of 89% of 195</span>

Answer:
x = 7
Step-by-step explanation:
You solve a linear equation by putting the variable on one side of the equal sign and a constant on the other side. Here, variables and constants are on both sides of the equal sign, so you need to separate them.
The basic idea is that you add the opposite of any term you don't want. Whenever you perform any operation (like "add"), <em>you must do it to both sides of the equation</em>.
We observe that x-terms have coefficients of 10 and 9. We choose to add the opposite of 9x to both sides:
10 -9x -5 = 9x -9x +2
x -5 = 2 . . . . simplify
Now, we still have -5 on the left, where we don't want it. So, we add its opposite (+5) to both sides:
x -5 +5 = 2 +5
x = 7 . . . . simplify
The solution is x = 7.

<em>Additional comment</em>
If we were to end up with an x-coefficient other than 1, we would divide both sides of the equation by that coefficient. This will leave the x-term with a coefficient of 1.
- The area of Kayla's dollhouse upstairs = 15.15 square feet
- The area of Kayla's dollhouse downstairs = 6.45 square feet
- To find the estimated Total area of Kayla's dollhouse, we would apply the Addition Operation
- The estimated total area is calculated using the formula :
Area of the dollhouse upstairs + Area of the dollhouse downstairs
Rounding to the decimals to the nearest tenth
- The area of Kayla's dollhouse upstairs to the nearest tenth = 15.2 square feet
- The area of Kayla's dollhouse downstairs to the nearest tenth = 6.5 square feet
15.2 square feet + 6.5 square feet = 21.7 square feet
The estimated total area of Kayla's dollhouse is 21.7 square feet
