What will the value of angle #2 be? Show your work.

Answers

Angle 2 would be 127 degrees because the angle that is 53 degrees and angle 2 create a supplementary angle, which equals 180 degrees. This results in the equation of 53 + angle 2 = 180, leaving angle 2 to be 127 degrees.

You have $65.00 in birthday money and want to buy some CDs and a DVD.
Suppose a DVD cost $15.00 and a CD cost $12.00. Write an inequality to find

Answers

Answer:

Step-by-step explanation:

L = 3*w + 1 Given

P = 2*(L + w) Formula for Perimeter. Substitute for L

P = 2*(3w + 1 + w) Combine

P = 2*(4w + 1)

P = 58 Given

58 = 8w + 2 Remove the brackets

58 - 2 = 8w Subtract 2

56 = 8*w Divide by 8

56/8 = w

7 = w

================

Find L

L = 3*w + 1

L = 3*7 + 1

L = 22

================

Check

2L + 2W = 58

2*22 + 2*7 =? 58

44 + 14 = ? 58

58 = 58

The answer checks.

The sum of five consecutive even integers is 220. Find the middle value of the five consecutive integers.

Answers

Answer:

Step-by-step explanation:

If we have odd number of consecutive numbers increasing by the same value (2) then the middle value of them is their mean:

220:5 = 44

Of course you can find them to be sure:

Consecutive even integers increase by 2.

So if 2x is the smallest of them (x is an integer), then the numbers are:

2x, 2x+2, 2x+4, 2x+6, 2x+8

So their sum: 10x+20

10x + 20 = 220 ⇒ 10x = 200 ⇒ 2x = 40

So the numbers are: 40, 42, 44, 46, 48

Simplify the expression. 1.7 – 2.7 – 1.34 + 4.9 – 1.48
please explain I'm lost

Answers

Answer:

Step-by-step explanation:

1.7 - 2.7 - 1.34 + 4.9 - 1.48

First we can group the positive and negative numbers

1.7 + 4.9 - 2.7 - 1.34 - 1.48

add the positive numbers then add the negative numbers

1.7 + 4.9 becomes 6.6

-2.7 - 1.34 - 1.48 becomes - 5.52

Now add both the answers

6.6 + (- 5.52) = 1.08

Winston owns a coffee cart. He charges $3.50 for a cup of coffee, and it costs him $1.50 to make each cup of coffee plus $100 a day for other expenses. Which equation can be used to determine how many cups of coffee, c, that Winston needs to sell each day in order to break even?

Answers

Answer:

50 cups of coffee

Step-by-step explanation:

So what you do is take 3.50 then subtract 1.50 to get the profit of one cup of coffee. ($2) Then you do the $100 and divide it by the $2 and find out how many cups of coffee he has to sell to get to the $100. (50)

for a new neighborhood, 100 acres of land will be split into 10 lots. how many acres of land will each lot have?

Answers

Your answer is 10 cause 100 divided by 10 is 10 :)

Each lot will have 10 acres of land.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find out how many acres of land each lot will have, you can divide the total amount of land (100 acres) by the number of lots (10).

So,

= 100 acres ÷ 10 lots

= 10 acres per lot

Therefore,

Each lot will have 10 acres of land.

For the first equation 6v+38≤ -4

The answer would be v≤-7

and for the second equation 2(v+3)≥-2

the answer would be v≥-4

Step-by-step explanation:

6v+38≤ -4

Subtract 38 from both sides

6v+38-38≤-4-38

Simplify

6v≤-42

Divide both sides by 6

6v/6≤-42/6

Simplify

v≤-7

SAME THING FOR THE OTHER

2(v+3)≥-2

Divide both sides by 2

2(v+3)/2≥-2/2

Simplify

v+3≥-1

Subtract 3 from both sides

v+3-3≥-1-3

And finally, simplify

v≥-4
