Answer:

Step-by-step explanation:

you can use x as the unknown number. we know 50%=1/2. we also know that 1/2 of x is 10

equation: 1/2x=10

now multiply both sides by 2 to isolate x

x=10 x 2, x=20

the unknown number is 20

125in is equal to how many ft and in? (show work)

Leno4ka [110]

125 inches is equal to 10 feet and 5 inches because 12 inches are in each foot. To find how many feet, you would do 125/12 which is 10 and a remainder of five. This means that 125 inches is equal to 10feet and 5 inches.

Answer:

Step 1: Distribute $-2$ to $5x$ and $8$

Step 2: Subtract from both sides of the equation $6x$

Step 3: Add to both sides of the equation $16$

Step 4: Divide both sides of the equation by $-16$

Step-by-step explanation:

Step 1: Apply the Distributive Property. Then you must distribute $-2$ to $5x$ and $8$

Then:

$-2(5x+8)=14+6x\\\\-10x-16=14+6x$

Step 2: You must apply the Subtraction property of Equality and subtract $6x$ from both sides of the equation. Then:

$-10x-16-6x=14+6x-6x\\\\-16x-16=14$

Step 3: You must apply the Addition property of Equality and add $16$ to both sides of the equation. Then:

$-16x-16+16=14+16\\\\-16x=30$

Step 4: You must apply the Division property of Equality and divide both sides by $-16$ . Then:

$\frac{-16x}{-16}=\frac{30}{-16}\\\\x=\frac{30}{-16}\\\\x=-\frac{15}{8}$
