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

Its asking a question that does not make sense to the listener. Comparing the question in answer option C to the other three answer choices, asking how long do you own a pair of shoes doesnt make sense. while the other questions ask stuff like what is the shoe size of the students, how may pairs do you have, or how much someone payed for something makes sense. But asking how long you own a pair of shoes does not. If the question were to be re worded, it would be something along the lines of: How long have you owned those pair of shoes?

You do 12.4 x 97.02 because that’s already length times width, and all you need to do is multiply the height.

Once you do that, you get 1,203.048,

then you divide that by 3 and you get 401.016

And that rounds to 401.1 ig

Part B: How can you decompose this parallelogram into two triangles? If this parallelogram was decomposed into two triangles, what would be the area of each triangle? (5 points)

Question 1 options:

Answers

Answer:

what do you want me to do?

Part A. The formula for finding the area of a parallelogram is A=bh where A is the area, b is the base and h is height.
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.
