31-12t = 211

A. combine 31-12
B. add 12 to both sides
C. add 31 to both sides sides
D. subtract 31 from both sides

Answers

Answer:

D. subtract 31 from both sides

you cant combine cuz theyre not like terms and you have to undo the constant number before you undo the second term in the equation so you will end up needing to do letter choice D first.

Step-by-step explanation:

hope this helped a little bit :)

Answer: D. subtract 31 from both sides

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

Explanation:

The expression 31-12t is the same as 31+(-12t). Adding a negative is the same as subtracting a positive.

Then we can flip the two terms getting -12t+31. This is because we can add two numbers in any order.

So we're effectively solving -12t+31 = 211

The first step is to subtract 31 from both sides to undo the +31. We follow PEMDAS in reverse to isolate the variable.

Answer:

Step-by-step explanation:

To solve this equation, we can combine like terms together:

Sarah Drew was the top scorer in a​ women's professional basketball league for the 2006 regular​ season, with a total of 856 points. The number of​ two-point field goals that Sarah made was 67 less than double the number of​ three-point field goals she made. The number of free throws​ (each worth one​ point) she made was 32 less than the number of​ two-point field goals she made. Find how many free​ throws, two-point field​ goals, and​ three-point field goals Sarah Drew made during the 2006 regular season.

Answers

Answer:

Free throws= 309 goals

Two-point field​ goals=341 goals

Three-point field goals=204goals

Step-by-step explanation:

This is a word problem, let us bring out all varibles

Let the number of three-point field goals =x

Two-point field goals=  2x-67

Free throws =(2x-67 )-32

     Free throws =2x-67-32

     Free throws =2x-99

Hence the mathematical expression for the total goals is

x+2x-67 +2x-99= 856

collecting like terms

x+2x+2x-67-99=856

5x-166=856

5x=856+166      

5x=1022

divide both sides by 5 we have

x=1022/5

x=204.4

hence

1. Three-point field goals=204goals

2. Two-point field goals=  2x-67

    =2(204)-67  

    =408-67

    =341 goals

3.  Free throws =2x-99

    =2(204)-99

    =408-99

    =309 goals

     

A carpenter is building a rectangular bookcase with diagonal braces across the back, as shown. The carpenter knows that mangle ADC is a right angle and that mangle BDC is 31° greater than mangle ADB. Solve an equation to find mangle BDC and mangle ADB.

Answers

Answer:

Step-by-step explanation:

Let <ADB be x. From the rectangle, <ADB+<BDC = <ADC

<ADB+<BDC = 90° ..... 1

If angle BDC is 31° greater than mangle ADB, then <BDC = x+31

Substituting the given values into the equation 1:

x+x+31 = 90

2x + 31 = 90

2x = 90-31

2x = 59

x = 59/2

x = 29.5°

To get <BDC, we will substitute x = 29.5° into the expression <BDC = x+31

<BDC = 29.5+31

<BDC = 60.5°

Hence <ADB = 29.5° and <BDC = 60.5°

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (-6, -3). What is the vertex of the function defined as
g(x) = -f(x) + 3?

Answers

Answer:

(6, 6).

Step-by-step explanation:

The negative before f(x) reflects f(x) in the x-axis so this makes the new vertex equal to (-6, 3), then the + 3 translates it up 3 units so the required vertex is

(-6, 6).

Answer:

Step-by-step explanation: quick maths

Answer:21/10Step-by-step explanation:Here we will simplify 84/40 to its simplest form and convert it to a mixed number if necessary.In the fraction 84/40, 84 is the numerator and 40 is the denominator.When you ask "What is 84/40 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.We do this by first finding the greatest common factor of 84 and 40, which is 4.Then, we divide both 84 and 40 by the greatest common factor to get the following simplified fraction:21/10 Therefore, this equation is true:84/40 = 21/10If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.21/10 = 2 1/10

2 hours 32 minutes

12 hours 14 minutes

3 hours 28 minutes

3 hours 32 minutes

Answers

Answer:

2 hrs and 32 mins

Step-by-step explanation:

Step 1. Because Inez worked more we are going to start by subtracting the the minutes. 23-51= -28.

Step 2. Now we move on to the hours. 7-4= 3. Know we know that the hour time is going to be three. But wait!

Step 3. Because we can't have negative numbers, we need to subtract some more. 60-28= 32. Now I know that my minutes will be 32.

Step 4. But because we used a negative number we have to subtract another hour from our time.

Answer: 2 hrs and 32 mins

Which is the length of the third side of the right triangle?
13 cm
30 cm

Answers

Answer: √731 ≈ 27.03701167

Use Pythagorean theorem to find this answer
a² + b² = c²
Let's say 13 is a and 30 is c
13² + b² = 30²
This gives you 169 + b² = 900
Subtract 169 from both sides and get b² = 731
Root both sides
√731 is already in the simplest form so that would be your final answer.
