Just Need A Little Help And Explanation On This One. I Always Mess Up And Get Confused, Which Causes

Answers

Answer 1
first you will convert -2 1/3 to an improper fraction which will leave you with -7/3 - (-5) then you remove the parentheses which will change -7/3 - -5 to -7/3+5 since two negatives = a positive. Then make the denominators the same by multiplying 5 by 3, then you have -7+15
———
3

then you will subtract -7+15 to get you
8/3 and then simplify the improper fraction to get the difference of 2 2/3

your final answer is 2 2/3

Obtuse Triangle

Step-by-step explanation:

The answers to number 1 for each triangle are solved exactly how they are written :).

The number 2s of each triangle are just numbers squared. 15 squared is 225. 18 squared is 324.

Triangle 1 is a right triangle because the angle is a right angle and the triangle can be solved perfectly using the Pythagorean Theorem.

Triangle 2 is an Obtuse Triangle because one side has a way larger angle than the other two angles.

Hope it helps!

Which statement describes the relationships between x and y in these two equations?

y = 3x

y = x + 3




In y = 3x, the value of y is 3 times the value of x, and in y = x + 3, the value of y is 3 more than the value of x.

In y = 3x, the value of y is 3 more than the value of x, and in y = x + 3, the value of y is 3 times the value of x.

In y = 3x and y = x + 3, the value of y is 3 more than the value of x.

In y = 3x and y = x + 3, the value of y is 3 times more than the value of x.
