2x + 9.75 - 7x= 5.15

Answers

Answer 1

Answer:

the answer would be X=0.82

Answer 2
the answer would be x=0.92




simplify 2x+9.75-7x=5.15
-5+9.75=5.15

subtract 9.75 from both sides
-5x=5.15-9.76

simplify 5.15-9.75 to -4.6
-5 = -4.6

divide both side by -5
x=-4.6/-5

simplify -4.6/-5 to 0.92
x=0.92

Janie is three years younger than her brother chad the sum of their ages is 27 how old is Janie

Answers

Answer:

Janie is 12

Chad is 15

Step-by-step explanation:

27 - 3 = 24

24 : 2 = 12

12 + 3 = 15 (Chad)

27 - 15 = 12 (Janie)

Janie is three years younger than her brother Chad and she is 12 years old

Janie is 3 years younger than her brother Chad.

let

Chad age = x

Janie age = x - 3

The sum of there ages is 27. Therefore,

x + x - 3 = 27

2x - 3 = 27

2x = 30

divide both sides by 2

x = 30 / 2

x = 15

Chad age = 15 years

Janie's age = 15 - 3 = 12 years

1) Mrs.Galicia sells online math and reading games. His revenue for each game (in dollars) is modeled by the given equations, where x is the number of days since the games went on sale.
Math Game: M(d)=x^2-9x-10
Reading Game: R(d)=2x+10
Solve the system algebraically. After how many days is the revenue for each game the same? Show your work and explain your answer.

Answers

Step-by-step explanation:

Given the following expression;

Math Game: M(d)=x^2-9x-10

Reading Game: R(d)=2x+10

x is the number of days since the games went on sale

In order to determine after how many days the revenue for each game wil be the same, we will equate M(d) to R(d)

M(d) = R(d)

x^2-9x-10  = 2x+10

x^2-9x-10 -2x-10 = 0

x^2-11x-20 = 0

factorize

x = 11±√121-4(-20)/2

x = 11±√121+80/2

x = 11±√201/2

x = 11±37.16/2

x = 11+37.16/2

x = 48.16/2

x = 24.06

Hence the revenue for each game will be the same after 24 days

It takes about 13 days for the revenue for each game the same.

Revenue is the amount of money made from selling a particular amount of products.

Given that the revenue is given by:

Math Game: M(d)=x²-9x-10

Reading Game: R(d)=2x+10

For both games to have the same revenue, hence:

M(d) = R(d)

x² - 9x - 10 = 2x + 10

x² - 11x - 20 = 0

x = -1.6 or x = 12.6

Since the number of days cannot be negative, hence it takes about 13 days for the revenue for each game the same.

if you have a pizza that has 24 slices and your friend eats 1/8 of it and you eat 1/3 how much is left

Answers

Answer:

13 slices

Step-by-step explanation:

The pizza has 24 slices. To figure out what 1/8 of 24 is, divide 24 by 8. To figure out what 1/3 of 24 is, divide 24 by 3. 1/8 of 24 is 3, and 1/3 of 24 is 8.

3 + 8 = 11 (number of slices eaten)

24 - 11 = 13 (number of slices left)

what is the area and perimeter of this triangle

Answers

Answer:

A = 2044 sqcm; P = 221 cm (PLEASE DOUBLE CHECK CALCULATIONS!!)

Step-by-step explanation:

the area of a triangle is half of its base times height.

the base and the height must be perpendicular to each other; so they would be 56 and 73.

56(73)/2=2044

the perimeter is the sum of all the sides

73+56+92=221

The area of the right-angled triangle is 2044 cm² and the perimeter of the right-angled triangle is 221 cm.

To find the area and perimeter of a right-angled triangle with dimensions 73 cm, 92 cm, and 56 cm.

Area of a right-angled triangle:

The area of a triangle can be found using the formula:

A = (1/2) x base x height

Plugging these values into the formula, we get:

A = (1/2) x 73 cm x 56 cm

A = 2044 cm²

Therefore, the area of the right-angled triangle is 2044 cm².

Perimeter of a right-angled triangle:

The perimeter of a triangle is the sum of all its sides.

In this case, the sides of the triangle are 73 cm, 92 cm, and 56 cm.

Perimeter = 73 cm + 92 cm + 56 cm

Perimeter = 221 cm

Therefore, the perimeter of the right-angled triangle is 221 cm.
