In this problem, we are given the equations of the two sides of a rhombus.

Equation 1 is 4 x – 10

Equation 2 is 2 x + 20

Since the given shape is a rhombus, therefore the two sides have equal sides. Hence, we can simply equate equation 1 and equation 2:

4 x – 10 = 2 x + 20

2 x = 30

x = 15

Therefore the answer is:

A. 15

Gina wants to take dance classes. She compares two dance studios to determine which has the best deal for her. Dance World charg

fomenos

Answer:

10 classes

Step-by-step explanation:

Given equations in the question

Dance World: y = 15x

Toe Tappers: y = 25 + 12.5x

Where,

x = number of classes

Equate the total cost at both dance studios

15x = 25 + 12.5x

Collect like terms

15x - 12.5x = 25

2.5x = 25

Divide both sides by 2.5

2.5x / 2.5 = 25 / 2.5

x = 10 classes

x = number of classes = 10

A fair die is rolled 5 times. What is the probability that a 3 is obtained on at least one of the rolls? Round your answer to th

Lerok [7]

Answer:

0.200

Step-by-step explanation:

The probability of obtaining a 3, in one roll of a fair die is 1/6.

Now, we have 5 rolls.

We now want to know the probability of a 3 showing up in at least one of the rolls.

This simply mean, we add the probabilities of three showing one time plus probability of three showing in 2 of the rolls e.t.c

This means we can have 3 showing up to 5 times.

We add the probabilities as follows:

(1/6) + (1/6)^2 + (1/6)^3 + (1/6)^4 + (1/6)^5 = 0.199974 = 0.200

I have a math problem that is stumping me and other people. Do you always multiple before dividing or do you work left to right?

swat32

It is customary to work left to right, however that is not a rule. In order of operations, the actual rule is that multiplication/division occurs after parentheses, exponents, and before addition/subtraction...

PEMDAS order of operations

Parentheses, exponents, mutiplication/division, addition/subtraction.
