Answer:

may i ask if this is geometry or algibra. i'll be able to help if i know what type of math it is.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Answer:

1: When adding integers that have the same sign make sure to keep the sign the same and only add the absolute of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

2: When subtracting integers keep the first number the change from subtraction to addition after that get the opposite sign of the second number (known as the subtrahend) Finally get the regular addition of integers.

3: When multiplying integers you have to first get the absolute of each number then multiply the absolutes then determine the sign for the final answer.

4: When dividing integers find the absolutes then divide the numbers and then simply find the sign (Usually positive)

Step-by-step explanation:

Hope I helped I'm learning integers also!

Part 1:

A - (4,9)

B - (6,3)

C - (1,3)

D - (8,7)

E - (8,9)

 To know where to put the dots on the graph, use the coordinates you've just been given:

Example: (4,8)

Move to the 4 on the x-axis (the line on the bottom going horizontal)

Then, move up 8 units (up to the 8 on the y-axis)

Place the point at that spot.

Part 2:

A - (1,2)

B - (2,4)

C - (3,6)

D - (4,8)

 Derek decorates 10 cookies in 5 minutes. We know he took 5 minutes to decorate 10 cookies because in the table, the x-axis is told to us that it represents the time it takes. Since the x coordinate is 5 in the point (5,10) and the y coordinate is 10, we can safely say that it took Derek 5 minutes to decorate 10 cookies.

Answer:

He can take 11 friends.

Step-by-step explanation:

110 - 20 = 90

Then you do simple math, how many times can 8 go into 90? Well, 8 times 10 is 80, so add 8 more and you have 88 (Which is 8 times 11).

90 - 88 = 2, so you can put in anymore.

Answer:

10)

No. Since the garage is a square, the length and width are the same. And since the formula to find the area of a square is (length times width) l x w , that means that the square root of 121 would be the length and width of the garage. The square root of 121 is 11, concluding that the car that measures 13 feet long is too large.

Kaylie needs 3 pounds of the 20% nickel metal to combine with 6 pounds of the 80% nickel metal to form an alloy containing 60% nickel.

To solve the problem, we can use the concept of weighted averages. The first step is to determine the amount of nickel in each metal before they are combined.

For the 20% nickel metal, 20% of the metal is nickel. Therefore, the amount of nickel in x pounds of this metal is 0.2x.

For the 80% nickel metal, 80% of the metal is nickel. Therefore, the amount of nickel in 6 pounds of this metal is 0.8(6) = 4.8 pounds.

Next, we can use the weighted average formula to determine the amount of nickel in the alloy:

0.2x + 4.8 = 0.6(x + 6)

Simplifying the equation:

0.2x + 4.8 = 0.6x + 3.6

0.4x = 1.2

x = 3

Therefore, Kaylie needs 3 pounds of the 20% nickel metal to combine with 6 pounds of the 80% nickel metal to form an alloy containing 60% nickel.

In summary, to determine the amount of metal-containing 20% nickel needed to combine with 6 pounds of metal containing 80% nickel to form an alloy containing 60% nickel, we used the concept of weighted averages and found that Kaylie needs 3 pounds of the 20% nickel metal.

The expectation to play the game is $2.5 and the fair price to play is $7.5.

The expectation is defined as the weighted average value of the random variable which is the product of the value of the random variable and its possibility.

Expectation= ∑P(win)*amount of win or loss of random variable

=∑x*P(x)

Here given that there are only two possible outcomes $5 and $10. And the possibility of every outcome is the same which is 0.5 as they occupy the same area.

As we know

Expectation= ∑P(win)*amount of win or loss of random variable

= 0.5(5-5) +0.5(10-5)

=0.5*0 + 0.5*5

=0+2.5

=$2.5

As fair price= expectation + cost of play

⇒fair price= $2.5 + $5

⇒fair price= $7.5

Therefore the expectation to play the game is $2.5 and the fair price to play is $7.5.

Answer:

B. x = -1

Step-by-step explanation:

-3(x - 2) = 9

Divide both sides by the coefficient of (x - 2) which is -3

[tex]\frac{-3(x - 2)}{-3} =\frac{9}{-3}[/tex]

x - 2 = -3

Add 2 to both sides of the equation

x - 2 + 2 = -3 + 2

x = -1
