-13x + 15x - 4y - 5y +2 + 3 please anwser

Answers

Answer 1

Answer:

2x - 9y) + 5

Step-by-step explanation:

(-13x + 15x) - 4y - 5y + 2 + 3

2x - 4y - 5y + (2 + 3)

2x - (4y - 5y) + 5

2x - 9y) + 5

We can't go any further because you can't add two different types of variables together (for example, you can't add x and y because they are diffrent variables.)

Hope this helps!

Question 1 options:

Answers

Answer:

what do you want me to do?

A=bh where b=8 feet ,h=3/4 foot and A=?
A=8*3/4
A=6 feet The area of the parallelogram is 6 feet square
Part B.You can decompose a parallelogram into two triangles by drawing a diagonal from one end to the another.The formula for finding the area of each triangle is A= 1/2bh where A is area b is base and h is height.Therefore:
A=1/2bh where b=8 h is 3/4 and A=?
A=1/2*8*3/4
A=3 feet square. Therefore the area of each triangle is 3 feet square.

What is the first step you would take to solve this equation, and why? 49n + 986 = -43.

Answers

Answer:

First step is to subtract 986 from both sides.

Step-by-step explanation:

I would subtract 986 from both sides because then it will balance out the equation; variable on one side and the number on one side. With this it will be easier to solve for n.

I would subtract 986 to each side to get 49n by itself then divide the coefficient 49n by itself to get N alone

Once you do that, you get 1,203.048,
