88 + 90 + 92 = ?

270 = 270

270/3 = 90

Answer 2

Answer: 90

Step-by-step explanation:

You just add up all the numbers then divide by how many numbers there are.

( 88 + 90 + 92 = 270 ) There are 3 numbers so take 270 / 3 = 90.

Answers

Answer: x = 9

Explanation:

Add the three angles up, and equal them to 180, as a triangle has 180*.

(13x + 2) + (3x - 4) + (5x - 7) = 180
Add together the like terms.
13x + 3x + 5x = 21x
2 + (-4) + (-7) = 9

21x + 9 = 180
21x = 189 (subtract 9 from both sides)
x = 9 (divide 21 from each side)

Given ΔPQR and ΔSTU, what is m∠Q?

Answers

Given that ΔPQR and ΔSTU are similar triangles, m∠Q = 64°.

Similar TrianglesThe ratios of the corresponding sides of similar triangles are always equal to each other, that is, the corresponding sides are proportional.Also, corresponding angles of two similar triangles are congruent.

Thus:

ΔPQR and ΔSTU are similar because:

PQ/ST = PR/SU = QR/TU = 3.5

Therefore,

m∠Q = 180 - 70 - 46

m∠Q = 64°

Thus, given that ΔPQR and ΔSTU are similar triangles, m∠Q = 64°.

2 1/5 - 5/6 =

Answers

Answer:

2 1/5 - 5/6 = 41/30

Step-by-step explanation:

Turn the denominator to be the same because if the denominator is not the same so you can't subtract neither can you add.

Next find the least common multiple of both denominator (5, and 6) and ask yourself what time the denominator would give you the least common multiply you got.

1/5 x 6/6 = 6/30 and 5/6 x 5/5 = 25/30

Your expression now would be 2 6/30 - 25/30

You can't subtract 6 from 25 so you have to turn the proper fraction into a improper fraction

2 6/30 = 2 x 30 + 6 = 66/30. 25/30 = 0 x 0 + 25 = 25/30.

Your new expression would be:

66/30 -  25/30

Now you can subtract 66 - 25 and you get 41

Therefore the correct answer is 41/30 you can not simplify the answer because the numerator is a odd number and the denominator is a even number.

The perimeter of a rectangle is 24 inches. The length is 2 inches. Use the numbers below to complete an equation to solve for the width, w. Numbers may be used once, more than once, or not at all.

Answers

24-2-2= 20. 20/2 = 10 width is ten

We want to find the width of a rectangle, we will find that the width is 10 inches.

Finding the width:

So we know that the perimeter of a rectangle is just given by:

P = 2*(L + W)

Where L is the length and W is the width.

Here we know that:

P = 24 inches

L = 2 inches

Replacing that we get:

24 in = 2*(2 in + W)

(24in)/2 = (2 in + W)

12 in = 2 in + W

12 in  - 2 in = 10 in = W

So the width is 10 inches.

y = 2x - 17

Step-by-step explanation:

y = mx + b

m = 2

y = 2x + b

Plug in (5, -7) for x & y.

-7 = 2(5) + b

-7 = 10 + b

Subtract 10 from both sides.

-17 = b

y = 2x - 17

Check work.

-7 = 2(5) - 17

-7 = 10 - 17

To simplify this expression and get an expression that is eual to 5x + 3y - 2x - 2y - 3 I used like terms :

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

(5x - 2x = 3x) + (3y - 2y = 1y or y)
