A

Step-by-step explanation:

f - g = (3x - 2) - (2x + 1) = x - 3

A

Answer:

  22

Step-by-step explanation:

Let x represent the number of houses on each street. Normally, Jake delivers 7x papers, and Ryan delivers 3x papers. On the day when Ryan delivered 45 of Jake's papers, we have ...

  (3x +45) > (7x -45)

  90 > 4x . . . . . . . . . . . add 45 -3x to both sides

  22.5 > x . . . . . . . . . . divide by 4

The number of houses on each street will be an integer, so the maximum number of houses on each street is 22.

_____

Additional comment

If Jake normally delivers more than 45 papers, then we must also have ...

  7x > 45

  x > 6 3/7

There must be at least 7 houses on each street.

Answer:

1/27

Step-by-step explanation:

If (-3, y) lies on the graph of y = 3^x, then we can find y by filling in the given x and calculating y

They gave us that x is -3 (the first number in an ordered pair is the x).

y = 3^x

y = 3^(-3)

y = 1/(3^3)

**You "fix" a negative exponent by pushing across a fraction bar; that changes the sign of an exponent**

y = 1/27

Because3^3 is 3×3×3 is 27

Answer:

See below.

Step-by-step explanation:

(5a^2 + 4ab – 3b^2) – (–5ab + 4b^2 + 3a^2)

5a^2+4ab-3b^2+5ab-4b^2-3a^2

(5a^2-3a^2)+(4ab+5ab)+(-4b^2-3b^2)

2a^2+9ab-7b^2

Answer:

You can answer this with modern calculators very easily.

Answer:

11y+22

Step-by-step explanation:

Answer and Step-by-step explanation:

For this equation, you need to use the distributive property. Before we can solve this, we need to know what the distributive property is. (Important:) The distribute property is where a number is directly outside the parenthesis and is multiplied to each number inside the parenthesis.

With that being said, let's rewrite this expression. Because 11 is outside the parenthesis, multiply it to each of the numbers inside the parenthesis. The numbers 11 x 2 = 22, so:

(y + 2)11 = 11y + 22.

We can remove the parenthesis now that the equation has changed. The reason why the 11 is in front of the y is because it is a coefficient. Coefficients always are written before a variable, which is the y in this case.

So, the answer is 11y + 22.

I hope that this helps.

Step-by-step explanation:

Game 1:

20 total numbers

Probability = Multiples of 3 and 7/Total Numbers

P = 8/20

P = 2/5 or 40%

Game 2:

20 total even or odd numbers

Probability = Number of even and odd/Total Numbers

P = 20/20

P = 1 or 100%

Game 3:

8 prime numbers and 1 = 9 total

Probability = Number of prime numbers or 1/Total Numbers

P = 9/20 or 45%

a) The probability of a multiple of 3 or a multiple of 7 is 40%.

b) The probability of even and odd is 100%.

c) The probability of the number being prime is 45%.

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Game 1:

20 total numbers

Probability = Multiples of 3 and 7/Total Numbers

P = 8/20

P = 2/5 or 40%

Game 2:

20 total even or odd numbers

Probability = Number of even and odd/Total Numbers

P = 20/20

P = 1 or 100%

Game 3:

8 prime numbers and 1 = 9 total

Probability = Number of prime numbers or 1/Total Numbers

P = 9/20 or 45%

Number lines are used to represent numbers and ratios using regular intervals

Nuka can weave 8.75 cm of strip in 5 minutes

Represent the ratio with:

Ratio = Length : Time

From the number line, they can weave 7cm of the strip in 4 minutes.

So, we have:

Ratio = 7cm : 4 minutes

Represent the length of strip made in 5 minutes with x.

So, we have:

x : 5 minutes = 7cm : 4 minutes

Remove the common units

x : 5 = 7cm : 4

Express as fraction

[tex]\frac x5 = \frac 74[/tex]

Divide 7 by 4

[tex]\frac x5 = 1.75[/tex]

Multiply through by 5

[tex]x= 8.75[/tex]

Hence, Nuka can weave 8.75 cm of strip in 5 minutes

Answer:

x+(2+x)+(4+x)+(6+x)= x+12

2x + 6+x = 3x +6

2+ x + 4+x= 2x + 6

Box has six sides as represented in the image. Since it is a square, you can multiply the 2 sides to find area of the square. 3.5x3.5=12.25 and since there are 6 sides, 12.25x6=73.5.

Answer:

Rule: A=50n

Step-by-step explanation:

Because each purse is 50 pesos, and n is the number of purses, and 50n would be the total cost, otherwise known as A.

Our rule is: A=50n

Then we insert 3 values for n, and solve to get the ordered pairs.

n=3 purses, A=3*50=150 dollars

n=4 purses, A=200 dollars

n=5 purses, A=250 dollars

Answer:

the answer would be -202

Step-by-step explanation:

since the number your starting with is 23 you would take 23 and × by 3 which gives you 69 then take -32 and subtract that by 69 then what ever you got for that you would multiply it by 2 and then get -202

Answer:

301, 35

Step-by-step explanation:

1st number = x, 2nd = y

x + y = 336

x = 126 + 5y

Then

(126 + 5y) + y = 336

6y = 336 - 126 = 210

y = 210/6 = 35

x = 126 + 5y = 126 + 5*35 = 301

Or x = 336 - 35 = 301

The two numbers are 301 and 35

Dilation involves changing the size of a square

The vertices of the image are (0,0), (5,10), (15,5) and (10,-5)

The vertices of the square are given as:

D(0,0), E(2, 4), F(6,2), and G(4,-2)

The scale factor (k) is given as:

k = 5/2

So, the image of the square is:

[tex]D' = 5/2 * (0,0) = (0,0)[/tex]

[tex]E' = 5/2 * (2, 4) = (5,10)[/tex]

[tex]F' = 5/2 * (6, 2) = (15,5)[/tex]

[tex]G' = 5/2 * (4,-2) = (10,-5)[/tex]
