Using Angle Relationships to Solve Equations

Answer:

1. 18

2. 181

3. 101

Step-by-step explanation:

They want you to take each equation, and replace the letter with the number they give you after the equation.

3m + 2n + 4; m = 2, n = 4

This becomes

3(2) + 2(4) + 4

We multiply before we add, according to the order of operations. So next, the equation becomes:

6 + 8 + 4

= 18

———-

D^2 + 9k ; D = 10, k = 9

Numbers squared are numbers multiplied by themselves.

(10)(10) + 9(9)

= 100 + 81 = 181

——————-

3m + 4y x 2 ; m = 7, y = 10

3(7) + 4(10) x 2

21 + 40 x 2

Remember, multiplication always comes before addition.

21 + 80 = 101

Answer:

$31.50

Step-by-step explanation:

So first thing, it's necessary to figure out what 30% of 45 is.

You can set this up as an algebraic expression or your can multiple 45 by 3/10 to find out what that 30% is.

The algebraic expression would be 30% of 45 is x.

Using one of these two options; we would discover that 30% of 45 is 13.5.

However, this is not the answer, yet.

The question is looking for the price of the dress after the 13.5 is taken away.

Therefore, you would subtract.

45 - 13.5 = 31.5

Sooooo... your answer is "The sale price of the dress is $31.50."

Answer:

B and C

Step-by-step explanation:

Mean is the average,

The total ages with 5 people would be 5 x 33 = 165

the total ages with the 6th person is 6 x 37 = 222

The age of the 6th person is 222 - 165 = 57 years old.

Answer:

The y-intercept is when the X is 0 And the y is whatever number it is. So in order to do that we need to find the pattern first and to do that we need to find the slope.

The slope here is 2/ 2 or 1.

So you add 1 to each side to find the next ordered pairs.

-5, -7

-4, -6

-3, -5

-2, -4

-1, -3

0, -2

So the y-intercept is -2.

Answer:

6°F

58°F

Step-by-step explanation:

From the data Given :

Temperature rise in Buffalo by noon time = 14°F

The initial temperature at Buffalo = - 8°F

Rise in temperature = 14°F

Therefore, temperature at noon = (-8 + 14)°F = 6°F

B.)

Temperature at 6am in St. Louis = 32°F

Temperature at 6am in Juneau = - 26°F

Temperature difference :

(32 - (-26))°F

32 + 26

= 58°F

Temperature in St. Louis is 58°F higher

Answer:

0.481

Step-by-step explanation:

P(A U B) = P(A) + P(B) - P(A∩B)

              = 0.3 + 0.43 - 0.249

              = 0.73 - 0.249

              = 0.481

Answer:

Simplifying

Answer:

volume of orange juice = 4 cans

Step-by-step explanation:

Recipe for orange juice

Orange juice concentrate = 1 can

Water = 3 cans

What is the volume of orange juice that you make?

volume of orange juice = Orange juice concentrate + water

= 1 can + 3 cans

= 4 cans

volume of orange juice = 4 cans

Answer: He bought 1 magazine and 3 comic books.

Step-by-step explanation: If comic books cost $1 and magazines cost $3, the equation for the problem should look like this: 2(m) + 1(c) = 5, since you know that the brother spent $5 in total. "m" represents the number of magazines purchased while "c" represents the number of comic books purchased. If you plug in 1 for "m" and 3 for "c", the equation would be true and would equal a total of $5. Also, 1 magazine and 3 comic books would mean that the little brother did, in fact, purchase 4 items.

Answer:

D

Step-by-step explanation:

They're not similar because the angle lengths are different.

Answer:

(a) Their rates of change differ by 2

Step-by-step explanation:

Given

See attachment for functions M and P

Required

Determine what is true about the rates of M and P

First, we calculate the slope (i.e. rate) of both functions.

Slope is calculated as:

[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]

From the table of M, we have:

[tex](x_1,y_1) = (-2,-9)[/tex]

[tex](x_2,y_2) = (2,11)[/tex]

So, the slope is:

[tex]m_M = \frac{11 --9}{2--2}[/tex]

[tex]m_M = \frac{20}{4}[/tex]

[tex]m_M = 5[/tex]

For function P, we have:

[tex]y = 7x + 9[/tex]

A function is represented as:

[tex]y = mx + b[/tex]

Where:

[tex]m = slope[/tex]

So, by comparison:

[tex]m_P = 7[/tex]

At this point, we have:

[tex]m_M = 5[/tex] --- Slope of M

[tex]m_P = 7[/tex] --- Slope of P

Only option (a) is true because both slopes differ by 2. i.e. 7 - 5 = 2

Other options are not true

Answer:

There are 16 nickels, 7 dimes, and 9 quarters.

Step-by-step explanation:

Aight, so lets set dimes as "x". Since there are 2 more quarters than dimes, quarters is "x+2". And since nickels is equal to dimes plus quarters, nickels takes the role of "(x+2)+x". We can simplify this by adding x and x together, so nickels is "2x+2" In this example, I'm converting these variables to cents, since it's easier than converting to dollars. Since a dime is 10 cents, 10 times x is"10x". Quarters are worth 25, so first we do x times 25 (25x) and then 2 times 25 (50). Then nickels. 2x+2 times 5 is 10x + 10. Alright, so now we have our cent values. $3.75 is 375 cents, so now we can make an equation:

10x + 25x + 50 + 10x + 10 = 375 cents.

I'm guessing you already know how to solve an equation, first combine like terms, then figure out how many times the variable goes into the numerical value. You should end up with 7, which is dimes. If we go back to our problem, we see that there are 2 more quarters, so 7+2= 9 quarters. As for nickels (9+7) there are 16 nickels.

There's probably a more efficient way to do this, but since I'm so... uh... inefficient, this is the best explanation I can do :p

Answer:

16 nickels 7 dimes 9 quarters
