Answer:

<h3>⇒ A. 2 should be distributed as 2y + 12, y = 6</h3>

Step-by-step explanation:

Here are the steps to solve this equation:

<u>Given:</u>

First step: 2(y+6)-4y

Use the distributive property.

<u>Distributive property:</u>

<h3>⇒ A(B+C)=AB+AC</h3>

2(y+6)

2*y=2y

2*6=12

2y+12

Isolate the term of y from one side of the equations.

2y+12=4y

Subtract by 12 from both sides.

2y+12-12=4y-12

Solve.

2y=4y-12

Then, you subtract by 4y from both sides.

2y-4y=4y-12-4y

Solve.

2y-4y=-2y

-2y=-12

Divide by -2 from both sides.

\sf{\dfrac{-2y}{-2}=\dfrac{-12}{-2}}

Solve.

Divide the numbers from left to right.

<u>Solutions:</u>

-12/-2=6

\Longrightarrow: \boxed{\sf{y=6}}

  • <u>Therefore, the correct answer is A. "2 should be distributed as 2y+12, y=6".</u>

I hope this helps. Let me know if you have any questions.

What is the measure of ∠x?
Dima020 [189]
The angle is a complementary angle so both angles add up to 90 degrees

Therefore set your equation equal to 90 to find angle of x

53+x=90

Subtract 53 from both sides

X= 37 degrees

5. A farmer puts apples into 36 crates. Each crate has 25 kilograms of apples in it. She sells 486,235 grams of apples. How many
Lynna [10]

There would be 413,765 kilograms after selling 486,235 grams of apples

How many grams make a kilogram?

In each kilograms, there are 1,000 grams, which means we need to first of all convert the total number of apples in kilograms to grams.

Each crate has 25 kilograms of apples in it

1 crate =25 kilograms

36 crates=36*25 kilograms

36 crates=900 kilograms

1 kilogram=1000 grams

900kilograms=1000*900

900 kilograms=900,000 grams

The number of grams left after having sold 486,235 grams of apples, in essence, the quantity of apples left thereafter is 900,000 grams minus the 486,235 grams of apples sold

apples left=900,000-486,235

apples left= 413,765 kilograms
