p/ 1 6/7=−4.4 help please!!!!!!!

Answers

Answer:

Sorry, I can't type well.

The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The equation is given below.

p / [1 ⁶/₇] = - 4.4

Convert the mixed fraction number into a decimal number. Then we have

1 ⁶/₇ = 1 + ⁶/₇

1 ⁶/₇ = 1 + 0.857

1 ⁶/₇ = 1.857

Then the equation is rewritten as,

p / 1.857 = - 4.4

Simplify the equation, then we have

p = - 4.4 x 1.857

p = - 8.17

The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.

PLEASE HELP The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.

Answers

Answer:

You can use the method of substitution and elimination.

Team A : Team B

        3x : 2x

       -12   +12

        5y : 4y

3x-12=5y ---> (1)

2x+12=4y ---> (2)

12x-48=20y

10x+60=20y

12x-48=10x+60

12x-10x=48+60

           = 108

2x=108

x=54

Original number of athletes on Team A = 3(54)

                                                                  = 162

Original number of athletes on Team B = 2(54)

                                                                    = 108

3,6,9,12= 4
2,4,6,8,10,12= 6

Answers

Answer:

See complete answer

Step-by-step explanation:

Backpack 2 is 2x, 2y, so double each number:

(0,2) = (0, 4)

(8,2) = (16, 4)

(6,5) = (12, 10)

(2,5) = (4, 10)

(0,2) = (0,4)

Backpack 3 is x + 8, y - 2 so add 8 to x and subtract 2 from y:

(0,2) = (8, 0)

(8,2) = (16, 0)

(6,5) = (14, 3)

(2,5) = (10, 3)

(0,2) = (8, 0)

Backpack 4 is x, 2y, so keep the same x and multiply y * 2

(0,2) = (0, 4)

(8,2) = (8, 4)

(6,5) = (6, 10)

(2,5) = (2, 10)

(0,2) = (0,4)

Find the total cost with tip.

Markup (tip $) = percent markup (tip %) x original cost ($)

Total cost = original cost + tip


Mr. Smith goes out to eat for his birthday. The total bill is $122.50. If Mr. Smith leaves a 20% tip, what is the tip amount? What is the total cost of the meal with tip included?

The tip is: $_________

The total cost of the meal is: $_________

Answers

Answer:

$147

Step-by-step explanation:

so to find 20% I usually divide the original cost by 100 to get 1% then multiply that number by 20.

in this case 122.50/100= 1.225, 1.225x20 = 24.5

a store sells laptops for 720 each. this price is 20 percent more than what it cost the store to buy each of them. before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost cost. how much would it cost an employee to purchase one of these laptops at the sale?

Answers

Answer:

462

Step-by-step explanation:

720 is 120% of the store price so to find the store price, we can muliply by the reciprical or 5/6.

720*5/6= 600

The employee can purchase the laptop at 23% off this price or at 77%. Multiply the price by 0.77 to get the employee price.

600*0.77 = 462

The total cost of the laptop at which an employee purchase is 482 and this can be determined by using the unitary method.

Given :

A store sells laptops for 720 each. This price is 20 percent more than what it cost the store to buy each of them. Before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost.

The following steps can be used in order to determine the total cost of the laptop at which an employee purchase:

Step 1 - The unitary method can be used in order to determine the total cost of the laptop at which an employee purchases.

Step 2 - According to the given data, 720 is the 120% cost at which the store sells. So, the value of the 100% cost is:

[tex]=\dfrac{720}{120}\times 100[/tex]

= 600

Step 3 - Now, the employee can purchase the laptop at a 23% discount that is 77% of the original cost.

Step 4 - So, the total cost of the laptop at which an employee purchase is:

[tex]=\dfrac{77}{100}\times 600[/tex]

= 462

Carl bought 19 apples of 2 different varieties to make a pie. The total cost of the apples was $5.10. Granny Smith apples cost $0.25 each and Gala apples cost $0.30 each. How many of each type of apple did Carl buy?

Answers

Answer:

Step-by-step explanation:

Split 19 into 2, since Carl bought two types of apples.

19/2 = 9.5

0.25 x 9 = 2.25

0.3 x 9 = 2.7

2.25 + 2.7 = 4.95

5.10 - 4.95 = 0.15

0.3 x 8 = 2.4

2.25 + 2.4 = 4.65

5.1 - 4.65 = 0.45

Answers

23.385+12.873=36.258

Answer=67.942

The mass of the container is 67.942 grams.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that amount of sugar is 23.385 grams, the amount of soda is 12.873 and the total mass is 104.2 grams.

The weight of the container will be calculated as below:-

Total weight of sugar and sods = 23.385+12.873=36.258

Weight of container = 104.2-36.258=67.942

Weight of container = 67.942 grams

Therefore, the mass of the container is 67.942 grams.
