x = 5/2 if you rearrange the terms, distribute, combine like terms, and subtract 5 from both sides the answer is 5/2
x=5/2

When there is a in front of an expression in parentheses, change the sign of each term in the expression

Distribute -5 through the parentheses

Collect like terms

Move variable to the left-hand side and change its sign

Move constant to the right-hand side and change its sign

Collect like terms

Subtract the numbers

Divide both sides of the equation by 12

Answers

Answer:

Yes

Step-by-step explanation:

Yes

The answer is -34 because all you have to do is substitute the x and y values for (8,6) where x = 8 and y =6.
So this is the equation: f(x,y) = 8 - ((8*6) - y)

How can you use the distributive property to multiply?



ILL GIVE U BRAINLIEST IF U GET IT CORRECT!!!

Answers

Answer:

1. 3/10 is equal to .3 or 30%

2. 7/10 is equal to .7 or 70%

3. The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = (30 +20) you can distribute the value outside of the parentheses to the values inside.

Answer:3/10 is 0.3 7/10 is 0.7 2/10 is 0.2

n math, distribution (also called the distributive property of multiplication over addition) allows you to split a large multiplication problem into two smaller ones and add the results to get the answer.

If you’ve ever tried to carry a heavy bag of groceries, you may have found that distributing the contents into two smaller bags is helpful. This is similar to how the distributive property works for multiplication.

Here’s an example: multiply 17 101 using the distributive property.

1. Simplify the numbers.

In this example, 101 = 100 + 1, so:

17 101 = 17 (100 + 1)

Split the problem into two easier problems.

Take the number outside the parentheses, and multiply it by each number inside the parentheses, one at a time.

= (17 100) + (17 1)

3. Add the products.

At this point, you may be able to solve the two multiplications in your head and then add them up easily:

= 1,700 + 17

= 1,717
