Serena is building a bookcase. She cuts two pieces of wood from one board. One piece is 1 7/8 feet long and another is 3 1/2 feet long. What is the total change in the length of the original board?

Answer:

78 - 83 - 88

Step-by-step explanation:

If you minus all the numbers together, you get

73 - 68 = 5

68 - 63 = 5

63 - 58 = 5

1) So, 73 + 5 = 78

2) Next is 78 + 5 = 83

3) Last, 83 + 5 = 88

Hope this helps!!!

The domain of the given function is [0,55] and the average rate of change is -1.45 so option (C) is correct.

A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.

The domain is for the independent variable while the range is for the dependent variable.

The domain of a function is the set of input values that the function defines.

The function goes from x = 0 to x = 55 thus  0 ≤ x ≤ 55 will be the domain.

The average slope for (0,80) and (55,0)

⇒ (0 - 80)/(55 - 0) = -1.45

Hence "The domain of the given function is [0,55] and the average rate of change is -1.45".

The answer is 3 because you can't multiply 20,7,14 well

Answer:

x = 50°

Step-by-step explanation:

Sum of Angles in a Triangle: 180°

All angles in a triangle must add up to 180°.

Step 1: Set up equation

x + 70° + 60° = 180°

Step 2: Solve for x

Answer:

50°

Step-by-step explanation:

Step 1:

x + 70° + 60° = 180°       Sum of a Δ

Step 2:

x + 130° = 180°         Combine Like Terms

Step 3:

x = 180° - 130°       Subtract 130° on both sides

Answer:

x = 50°

T = 2

Step-by-step explanation:

1. Distribute

2. Add the numbers

3. Order summands

4. Subtract 10 from both sides of the equation

5. Simplify

Answer:

t=2

Step-by-step explanation:

Simplify both sides of the equation.

16=4+3(t+2)

16=4+(3)(t)+(3)(2) (Distribute)

16=4+3t+6

16=(3t)+(4+6)(Combine Like Terms)

16=3t+10

16=3t+10

Step 2: Flip the equation.

3t+10=16

Step 3: Subtract 10 from both sides.

3t+10−10=16−10

3t=6

Step 4: Divide both sides by 3.

3/2= 6/3= t=2

Answer:

20.00-(13.55)= 6.45 in his bank account

Step-by-step explanation:

An addition equation is 20.00 + (-13.55) = 6.45 that represents the amount of money in his account.

Arithmetic operations can also be specified by the addition,  subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculations

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

Given that

There was a negative balance of −$13.55 in the account.

And Hayden made a deposit of $20 in order to pay the overdraft.

Determine an addition equation that represents the amount of money in his account.

According to the question, an addition equation that represents as

⇒ 20.00 + (-13.55) = 6.45

Hence, an addition equation is 20.00 + (-13.55) = 6.45 that represents the amount of money in his account.
