When you divide fractions, you multiply by the reciprocal.

The new equation would be:

[tex] \frac{5}{\frac{3}{8} \times \frac{8}{7} } [/tex]

[tex] \frac{5}{1} \times \frac{7}{3} = \frac{35}{3} [/tex]

Answer:

200/21

Step-by-step explanation:

5/(3/5) divided by 7/8

First divide 5 by 3/5. To do this you must write 5 as 5/1, and multiply 5/1 by the reciprocal of 3/5 (5/3).

5/1 (5/3)

numerator: 5*5=25

denominator: 1*3=3

25/3

Then divide 25/3 by 7/8 by multiplying 25/3 by the reciprocal of 7/8 (8/7).

25/3 (8/7)

numerator: 25*8= 200

denominator: 3*7= 21

200/21 or 9 11/21

The value of the expression 5w - (w/x) when w=6 and x=2 is 27.

The original expression given with the variables w and x is: 5w - (w/x). The question asks us to evaluate this expression when w=6 and x=2. So, we simply substitute w with 6 and x with 2 into the expression:

5*6 - (6/2) = 30 - 3 = 27

Therefore, the value of the expression 5w - (w/x) when w=6 and x=2 is 27.

Answer:

Step-by-step explanation:

Let

The relationship between x and y can be represented through a linear equation.

y = a . x + b

where,

a is the slope

b is the y-intercept

The slope refers to the price per print, that is, a = $0.15/p.

Then,

y = $0.15/p . x + b

Even if x = 0, there is a fixed cost of $3.00 (y = $3.00). We can replace these values in the expression above.

$3.00 = $0.15/p . 0 + b

b = $3.00

The final equation is:

y = $0.15/p . x + $3.00

If MaryAnn has $35,

$35 = $0.15/p . x + $3.00

$32 = $0.15/p . x

x = 213 p

She can order 213 prints.

The total cost y of a corporate team-building event can be expressed by the equation y = 1 + 1x, where x represents the number of attendees. This equation includes both the fixed and variable costs.

To determine the cost y of a corporate team-building event based on the number of attendees x, we need to include both the initial fixed cost and the variable cost per attendee.

The fixed cost of the event is $1, and the variable cost per attendee is also $1. The total cost can be expressed using the following equation:

y = 1 + 1x

Here:

For example, if there are 5 attendees, the total cost would be calculated as:

y = 1 + 1(5) = 1 + 5 = 6 dollars

To find the probability that the product of two standard dice is prime or ends in a 5, we need to count the favorable outcomes and divide it by the total number of possible outcomes. The probability is 1/4 or 0.25.

Explanation:

To find the probability that the product of two standard dice is prime or ends in a 5, we need to count the favorable outcomes and divide it by the total number of possible outcomes.

To have a prime product, the possible combinations are: (2,2), (2,3), (2,5), (3,2), (3,3), (3,5), (5,2), (5,3), (5,5)

To have a product that ends in 5, the possible combinations are: (1,5), (2,5), (3,5), (4,5), (5,5), (6,5).

The total number of favorable outcomes is 9.

When two dice are rolled, there are 36 total possible outcomes (6 possible outcomes for the first die multiplied by 6 possible outcomes for the second die).

Therefore, the probability that the product is prime or ends in a 5 is 9/36, which simplifies to 1/4 or 0.25.

Answer

y=-\frac{11}{13}x+\frac{8}{13}

Step-by-step explanation:

Answer:

y = -(11/13)x + (8/13)  

Step-by-step explanation:

recall slope intercept form of a linear equation takes the general form:

y = mx + b

In this case, simply rearrange the given equation such that it looks like the general equation above.

11x+13y=8  (subtract 11x from both sides)

13y = -11x + 8  (divide both sides by 13)

y = -(11/13)x + (8/13)    (answer)

The expression to determine the total amount Joe spent on gasoline and oil is 2.85 * g + 3.15 * c. If Joe bought 8.4 gallons of gasoline and 6 cans of oil, he will have spent 42.84 dollars in total.

Part A: To determine the total amount Joe spent on gasoline and oil, we need to calculate the cost of gasoline and the cost of oil separately, and then add them together.

The expression to calculate the cost of gasoline is: 2.85 * g, where 'g' represents the number of gallons of gasoline Joe bought.

The expression to calculate the cost of oil is: 3.15 * c, where 'c' represents the number of cans of oil Joe bought.

Therefore, the expression to determine the total amount Joe spent is: 2.85 * g + 3.15 * c.

Part B: If Joe bought 8.4 gallons of gasoline and 6 cans of oil, we can substitute these values into the expression we derived in Part A.

The total amount Joe spent can be calculated as follows:

Total amount spent = 2.85 * 8.4 + 3.15 * 6

Simplifying the expression:

Total amount spent = 23.94 + 18.90

Total amount spent = 42.84 dollars

Answer:

k = 5 and (6,2).

Step-by-step explanation:

Since (1,-1) is a solution of the equation 3x - ky = 8, so the point (1,-1) will satisfy the equation above.

Hence, putting x = 1 and y = -1 in the equation will give left-hand side = right-hand side.

So, 3(1) - k(-1) = 8

⇒ 3 + k = 8

⇒ k = 5 (Answer)

Therefore, the equation of the straight line is 3x - 5y = 8 ....... (1)

Now, putting x = 6 , then from equation (1) we get y = 2

Therefore, (6,2) is also a point on the graph of equation (1). (Answer)

Answer:

Biker will catch the cyclist after 2 hr and 40 min.

Step-by-step explanation:

Given:

Speed of Bicyclist = 20 km/h

Travelling time = 4 hrs

∴ Distance = Speed × Time = [tex]20\times4=80 \ km[/tex]

Also he rest for 1 hr.

So we can say that, after 5 hrs Bicyclist is 80 km ahead when the biker Started.

Now Biker rate is given 50 km/h

And Bicyclist rate is 20 km/h

So, for each hour, biker advances 50 - 20 = 30 kilometers

now bicyclist distance is 80 km

and biker advances 30 per hour.

Therefore to catch up bicyclist at 80 km i.e time taken to reach 80 km with 30 km rate per hour.

Time = [tex]\frac{80}{30}=2 \frac{2}{3} h[/tex]

Hence, Biker will catch the cyclist after 2 hr and 40 min.

A car is worth $300

Step-by-step explanation:

A board game allows players to trade and sell game pieces of equal value

We need to find how much the car is worth

Assume that the car is worth $x and the house is worth $y

∵ Player 1 traded three cars plus $100 for a house

∴ 3 x + 100 = y

- Subtract 100 from both sides

∴ 3 x = y - 100

- Subtract y from both sides

∴ 3 x - y = - 100 ⇒ (1)

∵ Player 2 sold two houses and a car for $2300

∴ x + 2 y = 2300 ⇒ (2)

Now we have system of equation to solve it

Multiply equation (1) by 2 to eliminate y

∵ 6 x - 2 y = - 200 ⇒ (3)

- Add equations (2) and (3)

∴ 7 x = 2100

- Divide both sides by 7

∴ x = 300

A car is worth $300

Option C: y = 80x is the right answer

Step-by-step explanation:

Varying directly means that the increase/decrease in one quantity will cause increase/decrease in other quantity.

If y varies directly with x it is given by::

y ∝ x

When the proportionality symbol is removed, a proportionality constant is introduced

y = kx

If x = 1/2 and y = 40

MOP = DAB

Step-by-step explanation:

the sides have to be matched up as well. the side with only one dash (MO) has to correspond with the side with one dash from the other triangle (DA). Thus, the letters in the sequence (MOP) have to match up in the same order (DAB)

The correct congruency statement with regards to the congruence of the triangles is the fourth statement

The details of the steps by which the congruence statement can be found can be presented as follows;

The marks on the segment indicates;

PO is congruent to BA

MO is congruent to DA

PM is congruent to BD

Therefore, the triangle MOP is congruent to the triangle DAB

The order in which the markings on the triangles are located can also be used to find the correct congruence statement

The name of the triangle MOP indicates that the vertice of the triangle between the segment with three marklings, III, and the segment with one marking, I, is considered first, which is the vertice M and D on each triangle

The next mentioned vertice is the vertice between the segment with one marking and the segment with two markings, which is the vertice O and A on each triangle

The third considered vertice is the third vertice on both triangles, which corresponds to the vertice P and B on each triangle

The congruency statement is therefore ΔMOP ≅ ΔDAB
