Answer:

|-10| + |-20| = 30

Step-by-step explanation:

Absolute Value

The absolute value of x, written |x| is a positive number that represents the distance from the origin and the number.

In practice, the absolute value is found writing the number without the negative sign, if present.

For example:

|-9| = 9

|76| = 76

|0| = 0

The given expression is

|-10| + |-20|

Calculate each absolute value separately:

|-10|=10

|-20|=20

Thus:

|-10| + |-20| = 10+20 = 30

|-10| + |-20| = 30

Answer:

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a

Given

| - 10 | + | - 20 |

= 10 + 20

= 30

2. Think of the top and middle shelves as two lines cut by a transversal. What type of angles are

nadya68 [22]

Answer:

Angles 1 and 5 are corresponding angles.

Step-by-step explanation:

These are the different types of angles formed by a transversal:

1. Corresponding angles are angles that lie on the same side of the transversal line. Angles 1, 3, 5, 6, 9, and 11 are corresponding angles because they are all on the left side of the transversal (the line that cuts through the other lines). Angles 2, 4, 6, 8, 10, and 12 are corresponding angles because they are all on the right side of the transversal.

2. Alternate interior angles are angles that are nonadjacent angles that lie on opposite sides of the transversal and in between the horizontal lines. Here the alternate interior angles are 3 and 6, 4 and 5, 7 and 10, and 8 and 9.

3. Alternate exterior angles are those that are nonadjacent and lie on the outside of the horizontal lines. In this diagram, angles 1 and 12 and angles 2 and 11 are alternate exterior.

4. Same-side interior angles are angles that lie on the same side of the transversal and in between the horizontal lines. The same-side interior angles in this diagram are angles 3 and 5, 7 and 9, 4 and 6, and 8 and 10.

A drop of water from a special dropper is 3 ml. How many liters is this? 30, 0.3, 0.03, 0.003.

Anni [7]

The answer is 0.003, because the two "00" in front of the three represent, tenths and hundredths, and the 3 is in the thousandths place

Which value of y forms the solution of the system defined by y = 11x + 1 and 11x + 12y = 12? (Select A - D from the screenshot)

alexandr1967 [171]

Answer:

y=1

Step-by-step explanation:

y = 11x + 1

11x + 12y = 12

Take the right side of the first equation, which is 11x + 1,

since y equals it, put it in parentheses like this (11x + 1)

and put it in place of y in the second equation.

The second equation is

11x + 12y = 12

Take out the y and put in (11x + 1) in place of the y:

11x + 12(11x + 1) = 12

Remove the parentheses by using the distributive principle:

11x + 132x + 12 = 12

Combine like terms on the left

143x + 12 = 12

Subtract 12 from both sides

143x = 0

Divide both sides by 143

x = 0

Now go back and get the very first equation:

y = 11x + 1

And substitute (0) for x:

y = 11(0) + 1

y = 0 + 1

y = 1

What is the solution to the equation show your work 3/5(x-5/8) =1/12-x+7/8

Nonamiya [84]

1. distribute

step 1: 3 3

----- × X = ------X

5 5

3 5 3 Ima convert this into a decimal

------- × - ----- = - ------ ----> negative .375

5 8 8

2. write the problem now

3 1 7

----- X - 0.375 = ---- - X + ----

5 12 8

3. I would convert them into decimals and solve

0.6x - 0.375 = 0.08 - x + 0.875

+x +x

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

1.6x - 0.375 = 0.08 + 0.876

1.6x - 0.375 = 0.956

+0.375 +0.375

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

1.6x = 1.331

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

1.6 1.6

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

x = 0.831875

rounded up : 0.83
