Answer:

4x + 1

Step-by-step explanation:

Multiply f + g by x because f + g is in parenthesis:

f(x) + g(x)

Then implement equation #1 for f(x) into our equation:

3x - 1 + g(x)

Then implement the other equation for g(x) into our equation:

3x - 1 + x + 2

Then switch the positions of -1 and +x:

3x + x - 1 + 2

Simmplify:

4x + 1

Step-by-step explanation:

This question is incomplete because part of the information is missing; here is the complete question:

Jeremiah's dad ordered 5 large pepperoni pizzas and 8 large cheese pizzas for the birthday party. He spent a total of $144 on pizza. If a pepperoni pizza costs $12, write and solve a linear equation to find the cost of a cheese pizza.

The answer to this question is $10.50

Explanation:

The first step to solve this problem is to write a linear equation. In this, the unknown should be represented by an x, and other variables should be included using correct mathematical symbols. Here is the process:

1. In an equation there is always an equality symbol = and mathematical expressions on both sides.

2. In this situation, the value after the = symbol should be 144 or the total spend on pizzas.

3. The values missing should be expressed as 5 (12) + 8x because there are 5 pepperoni pizzas and each of these costs $12; also, this should be added to the 8 cheese pizza and x represents the missing value (the price of a cheese pizza.)

4. Solve the equation

5 (12) + 8x = 144 -Simplify using multiplication

60 + 8x = 144 - Solve by moving the number to the right side and changing the symbol

8x = 144 - 60

8x = 84

x = 84 ÷ 8

x = 10.5

Answer:

A

Step-by-step explanation:

Let's see what to do buddy....

[tex]T = b + \frac{d}{2f} \\ [/tex]

Subtract sides b

[tex]T - b = b - b + \frac{d}{2f} \\ [/tex]

Simplification

[tex]T - b = \frac{d}{2f} \\ [/tex]

Multiply sides by 2f

[tex](T - b)(2f) = d[/tex]

So ;

[tex]d =( T - b) \times (2f)[/tex]

We're done but i wanna go one step more...

[tex]d = T \times 2f - b \times 2f[/tex]

[tex]d = 2Tf - 2bf[/tex]

P(A|B) = 1/3

"A Venn diagram in mathematics is a diagram that uses overlapping circles or other shapes to represent the logical relationships between two or more sets of items. "

"For any experiment, a probability denotes the possibility of outcome for any event."

For event A, the probability of event A is,

P(A) = number of favorable outcomes/ total umber of outcomes

"Conditional probability is the probability of an event occurring given that another event has already occurred."

P(A|B) = P(A∩B)÷P(B)

For given diagram:

Let A represents a set of students playing Basketball and B represents a set of students playing Soccer

So, A = {Fran, Ian, Juan, Ella}

⇒ n(A) = 4

B = {Mickey, Marcus, Ella}

⇒ n(B) = 3

(A ∩ B) = {Ella}

⇒ n(A ∩ B) = 1

sample space: S = {Fran, Ian, Juan, Ella, Mickey, Marcus, Mai, Karl, Jada, Gabby}

⇒ n(S) = 10

Now, we calculate probability of B and A∩B.

P(B) = n(B)/n(S)

⇒ P(B) = 3/10

Also, P(A∩B) = n(A∩B) / n(S)

⇒ P(A∩B) = 1/10

So, the required probability would be,

⇒ P(A|B) = P(A∩B) ÷ P(B)

⇒ P(A|B) = (1/10) ÷ (3/10)

⇒ P(A|B) = 1/3

Therefore, P(A|B) = 1/3

So first find the greatest common factor of the denominators

GCF of 2 , 4 and 8 is 8

Then :

[tex]\frac{-4 + 6 - 3}{8}[/tex]

So you do this to get the above answer:

8 divided by the denominator times the numerator.

Answer:

I believe 600

Step-by-step explanation:

20% = 0.2

so multiply the 500 by 0.2

500×0.2= 100

then add 100 to the 500 because its an increase

500+100=600

and then you have your answer

Answer:

19040 grams

Step-by-step explanation:

Dan used the amount of flour each day = 0.68 kg

He used the flour for 4 weeks.

So the number of days taken by Dan = 4 × 7 = 28 days

Now amount of flour used in 28 days = Flour used in a day × Number of days

= 0.68 × 28

= 19.04 kg

Since 1 kg = 1000 grams

Therefore, 19.04 kg = 1000 × 19.04 = 19040 grams

Dan used 19040 grams of flour in 4 weeks.

The number of grams of flour that was used is 19040 grams.

Since Dan used 0.68 kilogram of flour each day for 4 weeks, this means that the flours used will be:

= 0.68 × 4

= 2.72kg

Therefore, 2.72kg will be converted to grams and this will be:

= 2.72 × 1000 = 2720 grams

Now, we'll multiply the value by 7 since there are 7 days in a week. This will be:

= 2720 × 7 = 19040

Answer:

the answer is 200

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

The total cost for producing x number of shirts = 100 + 7x

The price of each shirt is $15, therefore:

Revenue = price per shirt × number of shirts = 15 × x = 15x

Revenue = 15x

The cost of making 25 shirts is given as:

Cost = 100 + 7x = 100 + 7(25) = $275

The money earned from producing 25 shirts is given as:

Revenue = 15x = 15(25) = $375

Since the revenue is greater than cost, the students would make more money than they spent if they make and sell exactly 25 shirts

Maxwell is faster and faster by 0.5 miles/hour.

Given that, Hayley jogs 3/4 miles in 1/6 of an hour and Maxwell jogs 2/3 miles in 2/15.

We need to find who is faster and how much faster.

An average speed is the total distance travelled divided by the total time travelled. The formula to find the average speed is Average speed = Total distance / Total time.

Now speed of Hayley= 3/4 ÷ 1/6

=3/4 × 6=9/2

=4.5 miles/hour

Speed of Maxwell= 2/3 ÷ 2/15

= 2/3 × 15/2 = 5 miles/hour

The difference in the speed =5-4.5=0.5 miles/hour

Therefore, Maxwell is faster and faster by 0.5 miles/hour.
