line 1: 16 + 3x + 5 + 2x
line 2:2x + 3x + 5 + 16
line 3:5x + 21

Answers

Answer 1

Answer: Commutative Property of Addition

This property says that A+B = B+A. The order of addition doesn't matter.

As an example, 2+3 = 3+2 since both sides evaluate to 5.

To find the value of v, we must substitute the values of u & t in the equation v = u + 5t.

Acellus Find the next term in this arithmetic sequence. 7/2,9/4,1,-1/4,-2/3 ,___​

Answers

Answer:

-11/4

(I think you meant -3/2 not -2/3 at the end there.)

Step-by-step explanation:

If it is arithmetic, it's going up or down by same number.

So we started with 7/2 and went down to 9/4.

If we can find how much it went down, then we can find the next term after -3/2.

Find difference

7/2-9/4

Find common denominator

14/4-9/4

5/4

So we are going down by 5/4 each time.

That means the following equations should ve true:

7/2-5/4=9/4

9/4-5/4=1

1-5/4=-1/4

-1/4-5/4=-3/2

And all of these are in fact true.

The next term in the sequence will be

-3/2-5/4.

Find common denominator

-6/4-5/4

-11/4

For the triangles to be similar by the SSS similarity theorem, what must be the value of y?

Answers

Answer:

20

Step-by-step explanation:

Took the cumulative exam on Edge

The value of y in the given similar triangles is 20.

What are the similar triangles?

Two triangles are said to be similar if their corresponding angles are congruent to each other and the corresponding sides are in equal ratios.

Given are two triangles, we need to find the value of y so that the triangles be similar by SSS rule,

If the figures are similar by SSS Similarity Theorem, then the ratio of its corresponding sides must be proportional,

So,

14/28 = 10/y

y = 20

Hence, the value of y in the given similar triangles is 20.

Problem 3

Answer:  1/5 of a gallon per minute

-------------------------

Explanation:

Two points from the graph are (10,2) and (20,4)

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (4-2)/(20-10)

m = 2/10

m = 1/5

The slope of the graph is 1/5.

Do the same for two points from the table. I'll use the first two rows

m = (y2-y1)/(x2-x1)

m = (4-2)/(10-5)

m = 2/5

The slope of the table is 2/5.

Subtract the two slopes to wrap things up:

2/5 - 1/5 = (2-1)/5 = 1/5

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2+b^2= c^2  where a and b are the legs and c is the hypotenuse

20^2 + 21^2 = c^2

400 +441 =c^2

841 = c^2

Take the square root of each side

sqrt(841) = sqrt(c^2)

29 = c

Answer:

c = 29 km

Step-by-step explanation:

21² + 20² = c²

Answers

Answer:

27 cubic feet

Step-by-step explanation:

A pyramid is always 1/3 of a cube when it has the same base as a pyramid.

ALSO, thats why the volume of a square pyramid has 1/3 in it.

So, if the volume of this pyramid is 9 cubic feet then:

9 x 3 = 27 cubic feet
