p - 1.04(xd – 22)
p - (1.04xd + 22)
(1.04xd +22) - p

Answers

Answer:

p - (1.04xd + 22)

Step-by-step explanation:

Tyanna bought x number of shares for d dollars ⇒ xd

paid a 4% commission ⇒ 0.04 xd

Tyanna paid = xd + 0.04xd = 1.04 xd

She sold the stock for p dollars ⇒ p

paid a flat fee of $22

The sell price = p - 22

Net = p - 22 - 1.04xd = p - (22 + 1.04 xd)

The answer is option ⇒ p - (1.04xd + 22)

teams of four are competing in a quarter mile relay. each runner must run the same exact distance. what is the distance each teammate runs?

Answers

Each teammate runs 1/16 miles.

Further Explanation

Given:

There are four people in a team
The running distance is 1/4 mile
Each runner must run the exact distance

Question:

what is the distance each teammate runs?

Each person will run = the total distance

number of person in a team

$\boxed {= (1)/(4) : 4 }$

we can write that equation in multiplication form as follow:

$\boxed {= (1)/(4) *(1)/(4) = (1)/(16) }$

So, each person in the team will run $\boxed {(1)/(16) }$ miles

A quarter is 1/4, and each runner runs 1/4 of that distance, so multiply the two numbers together to find the distance run by each runner: 1/16 of a mile, or 0.0625 miles.

HELP!!!! Please?! Solve the equation below, and check the solution. -6x+7=79 the solution set is? BRAINLIEST ANSWER

Answers

Alright so, in order to solve an equation, you must have the unknown by itself.

So, we first subtract 7 from both sides and get a new equation.

-6x = 72

Now we divide by -6 so that x is by itself.

x = -12.

Now, -12 is a *possible* solution to the equation. The way to find out is to check. Checking the answer means "plugging in" the number into the equation, and seeing if it solves. so.

-6 * -12 + 7 = 79

72 + 7 = 79

79 = 79

So, since the answer checked out, -12 is a solution to the equation.

Hope this helps.

Three friends fill bags with trash at a neighborhood cleanup. Randall's bag weighs 3x-7 pounds, Seth's bag weighs 2x - 10 pounds, and joanna's bag weighs 2x+2 pounds. Together, Randall's and Joanna's bags weigh 3 times as much as Seth's bag. How many pounds of trash does each friend pick up?

Answers

Final answer:

To solve this problem, set up an equation using the given weights and solve for 'x' to find the weights of each friend's bag.

Explanation:

To solve this problem, we need to set up an equation based on the given information.

First, let's express the weights of Randall's, Seth's, and Joanna's bags in terms of 'x':

Randall's bag: 3x - 7 pounds
Seth's bag: 2x - 10 pounds
Joanna's bag: 2x + 2 pounds

According to the problem, Randall's and Joanna's bags together weigh 3 times as much as Seth's bag. Mathematically, this can be written as:

(3x - 7) + (2x + 2) = 3(2x - 10)

Solving this equation will give us the value of 'x', which we can then use to find the weights of each friend's bag.

Answer:

Randall=68 pounds, Seth's=40, Joanna's=52

Step-by-step explanation:

Randall's = 3x-7

Seth's = 2x-10

Joanna's = 2x+2

Randall's + Joanna's = 3 (Seth's)

Find X:

Form into an equation (add parentheses)
(3x-7) + (2x+2) = 3 (2x-10)
REmove parentheses on left side
3x-7+2x+2 = 3 (2x-10)
Distribute right side
= 6x-30
3x-7+2x+2 = 6x-30
Combine like terms
5x-5=6x-30
subtract 5x from BOTH sides (always subtract, add, multiply, and divide both sides at the same time)
-5=x-30
Add 30 to BOTH sides
25=x

Find how many pounds of trash each friend picked up:

Randall's:

3x-7
plug in x
3(25)-7
Distribute
75-7
= 68

Seth's:

2x-10
2(25)-10
50-10
= 40

Joanna's:

2x+2
2(25)+2
50+2
=52

Double check your answers:

Randall's+Joanna's= Seth's(3)

68+52=40(3)

120=120

Find the unit rate with the second given unit in the denominator. $67.50 for 9 pizzas

A.$15/pizza

B.7.50pizza/$

C.15pizza/$

WORTH 8 POINTS!!!!

D.$7.50/pizza

Answers

To find unit rate:
divide the top number by the bottom number

the fraction in this problem is 67.50/9
so you divide 67.50 ÷ 9 = 7.5
since the unit rate we are looking for happens to be money, you have to have 2 digits after the decimal, so add a zero to make 7.5 into $7.50

It is $7.50 per pizza, so the correct answer is D.
:))))))))))))

It is 7.50. 6750/9 = 750 just right the decimal $7.50
