What is the solution to the following equation?
(5x-2)^2=10

Answers

Answer 1

Answer: take the square root of both sides to get rid of parenthasees, remember to get the positive and negative root
5x-2=+/-√10
add 2 to both sides
5x=2+/-√10
divide by 5
x= $(2+/- √(10) )/(y)$

x= $(2+ √(10) )/(y)$ or $(2- √(10) )/(y)$

aprox
x=1.03246 or -0.232456

What is the probability of rolling
a cube and having it land as a
six?

Answers

Answer: 1/6 cause there is 6 sides to a cube and ur only wanting one number

Final answer:

The probability of rolling a cube (in this context, a die) and it landing on a six is 1 out of 6, or approximately 0.167.

Explanation:

The probability of an event happening is calculated by dividing the number of successful outcomes by the total number of possible outcomes. When rolling a cube (which I'm assuming you mean a cube shaped dice called a die), there are six possible outcomes - landing on a 1, 2, 3, 4, 5, or 6. In this case, we are looking for the event of the die landing as a six. Since there's only one side with a six among the six total sides, the probability is one out of six, often expressed as 1/6 or approximately 0.167 when rounded to three decimal places.

What is the sum of 2/5 and 2/4?

Answers

a/b+c/b=(a+c)/b
make bottom number same

multiply by 1 or x/x where x=x
easy way is
if you had
a/b+c/d
multiply a/b by d/d and multiply c/d by b/b

2/5 times 4/4=8/20
2/4 times 5/5=10/20

add

8/20+10/20=(8+10)/20)=18/20=9/10

I should have simplified 2/4 to 1/2 first

18/20 because you can't add 5 and 4 so you make the denominator the same so you just multiply 5×4 and 4×5this will give you 8/20+10/20=18/20

Karl rides his bicycle 120 feet in 10 seconds. How many feet does he ride in 1 minute?

Answers

take 120 and *times it by 6 because there are 60 seconds in a minute. So you answer is . does that help?

120/10 to find his feet per second which is 12 feet per second

12*60

since there are 60 seconds in a minute

= 720

A single fair is tossed. find the probability of rolling a number grater than 4

Answers

Probability of the outcome you're looking for =

(number of ways your outcome can happen)
divided by
(total number of possible outcomes) .

Total number of possible outcomes when a single fair is tossed = 6 .

The outcomes you're looking for: 5 or 6 . (two of them) .

Probability = 2 / 6 = 1/3 = 33-1/3 %

Solve equation: –6 + 3x = –9
