(x - 3) = 9

Answers

Answer 1
Answer: Peter started with 21 cards
( also your bottom formula is wrong it should be 1/2(x-3)=9)

An inscribed angle is an angle formed by two radii that share an endpoint A) True
B)False

Answers

check the picture below.

notice, as from the left, we grab those two angles and slap them together on the right, they form a wide angle A, and a smaller inscribed angle B.

now, the blue and red segments that came together, are both making up the inscribed angle B, and also sharing the side or endpoint, in the middle of angle A.

You have a piggy bank containing a total of 106 coins in dimes and quarters. If the piggy bank contains $17.05, how many dimes are there in the piggy bank? There are how many dimes in the piggy bank.

Answers

Answer:

63 dimes

Step-by-step explanation:

Set up a system of equations where d is the number of dimes and q is the number of quarters:

d + q = 106

0.1d + 0.25q = 17.05

Solve by elimination by multiplying the top equation by -0.25 to eliminate q:

-0.25d - 0.25q = -26.5

0.1d + 0.25q = 17.05

Add together and solve for d:

-0.15d = -9.45

d = 63

So, there were 63 dimes in the piggy bank

Final answer:

The slope of line PQ calculated using the the formula (y₂-y₁)/(x₂-x₁) comes out to be -3 as given in the question. However, the complete information for line S is not provided, so its slope cannot be calculated.

Explanation:

The question is related to the types of lines formed by the given points in a Cartesian plane. Here, m(PQ) and m(S) represent the slopes of the lines formed by points P and Q, and line S respectively.

We calculate the gradient or slope of a line using the formula m = (y₂-y₁)/(x₂-x₁) where (x₁, y₁) and (x₂, y₂) are the coordinates of two distinct points on the line.

So, for line PQ the slope m(PQ) = (-1-14)/(2-(-3)) = -15/5 = -3. This matches the value given for m(PQ) in the question, thus establishing that PQ is a line with slope -3 in the Cartesian plane.

However, you haven't provided the complete information about the line S (only one coordinate is given). So, we cannot compute its slope. Please check the information given.

Step-by-step explanation:

Craig Browning bakes cookies for the elementary school cookie sale. His chocolate chip cookies sell for $1.00 a dozen, and his oatmeal brownie cookies sell for $1.50 a dozen. He will bake up to 20 dozen chocolate chip cookies, and up to 40 dozen oatmeal brownie cookies, but no more than 50 dozen cookies, total. Also, the number of oatmeal brownie cookies will be no more than three times the number of chocolate chip cookies. How many of each kind should Craig make in order for the elementary school to make the most money

Answers

Answer and Step-by-step explanation:

Let

Number of chocolate chip cookies = x

Number of oatmeal brownie cookies = y

Bake chocolate chip cookies up to 20 dozen = x≤ 20

Bake oatmeal brownies up to 40 dozen= y≤40

Total cookies = x + y ≤ 50

Number of oatmeal brownie will be no more than three times the number of chocolate chip= y≤3x

From the inequality:

                        X + y=50                          

                         y = 3x

By putting the value of y, we get

    x + 3x = 50

     4x = 50

    X = 12.5

By putting the value of x=12.5 in equation y = 3x, we get

Y = 3(12.5)

    = 37.5

Craig should make 12.5 dozen chocolate chip and 37.5 dozen oatmeal brownies in order to make more money.
