Amy is thinking of a number that is 2 times the value of jake's number.Amys number is also 2 more than 3 times the value of jake's number.What is amys number? Write and solve a system of equations to answer the question. A.4
B.2
C-2
D.-4

Answers

By solving a system of equations, we will see that Amy's number is -4.

How to find the system of equations?

First, we define the variables:

  • A = Amy's number.
  • J = Jake's number.

From the text, we know that:

A = 2*J

A = 2 + 3*J

This is the system of equations we need to solve.

To do it, we can write:

2*J = 2 + 3*J

Now we solve this for J

-2 = 3*J - 2*J = J

Then Jake's number is -2

And Amy's number is:

A = 2*J = 2*(-2) = -4

A group of students went out for lunch after their examination. They were to
share the expenses equally. The total bill
was R200. Ten of the students did not
have any money, so each of the others
had to pay an extra R1. Determine the
number of students in the group.

Answers

number sof student of the group is 50

Step-by-step explanation:

let the number students be x

total bill is Rs 200

each student will pay =200/x

now 10 students do not have the money

so x - 10 students will pay the bill of Rs 200

according to the problem

= + 1

or, - = 1

or, 200 ( - ) = 1

or, 200() = 1

or, 200 X 10 = x(x-10)

or, - 10x - 2000 = 0

or, - 50x +40x - 2000 =0( using middle term factor)

or, (x - 50) (x+40) = 0

x = 50 ( x = -40 for number of students it is not possible)

What is Mean?

A mean is an arithmetic average of a set of observations. it is given by the formula,

As it is given that Meg has 2 berries, Paul has 2 berries, Mia has 5, Yen

has 7, and April has 9. Therefore, the total number of berries with them will be,

As the total number of berries is 25, while the total number of people is 5, therefore, the number of berries with each person after distribution will be,

°.

Answers

the required answer is 23°

Step-by-step explanation:

you can apply basic property of rectangle to solve this question.

each angle of a rectangle is 90°

now, ∠ABD + ∠CBD = 90°

or, ∠CBD = 90° - 67° ( given ∠ABD = 67°)

= 23°

Answer:
The length of AC is 8 and the length of CBD is 23
Step-by-step explanation:
AC is equal to BD and ABD has an angle of 67, and since it is a rectangle all angles are 90 degrees so 90-67=23 which gives you the angle for CBD

Step-by-step explanation:

Amir and Edward are twins, They want to invite their friends to celebrate birthday party at a bowling alley. They have a budget of $200 to plan their party. The party room at the bowling alley costs $55.99 to rent and includes a free birthday cake. The bowling alley charges each person $5.50 to bowl and pair of bowling shoes. Amir writes an equation that represents the cost of their birthday party, Edward writes an inequality. Both use p to represent the number of people that can attend. A. Write an equation Amir used and an inequality Edward used to represent the cost of their birthday party. Each brother believes that their statement best represents the situation. Amir thinks that his equation is the best representation for the situation. Edward argues that his inequality is the best representation for the situation. B. Which brother's statement best represents the situation? Explain.

Answers

Answer:

A.

Amir's equation : 5.50 p + 55.99 =200

Edward's equation : 5.50 p+ 55.99 ≤ 200

B. Amir's equation presents the situation best because it gives the cost of the part as per the budget. Edward's equation gives room for lesser amounts to be used in case p< 26.

Step-by-step explanation:

The budget is $200

The party room charges $55.99

The charge per person is $5.50

Letting p =number of people that can attend the party, then

A.

Equation for cost that Amir use is;

$5.50*p + $55.99 = $200

5.50 p + 55.99 =200

5.50 p = 200-55.99

5.50 p =144.01

p= 144.01/5.50 = 26 -------Amir's equation will also give the number of people that can attend the party with the budget of $200

For Edward's case

$5.50 p +$55.99 ≤ $200

5.50 p+ 55.99 ≤ 200

5.50 p ≤ 200-55.99

5.50 p ≤ 144.01

p ≤ 144.01/5.50

p ≤ 26

Edward's inequality suggests that for the budget of $200 , 26 or less people can attend the party.

B. Amir's equation presents the situation best because it gives the cost of the part as per the budget. Edward's equation gives room for lesser amounts to be used in case p< 26.
