What's 7/8x4/5? Cmon peeps it's hard

Answers

Answer 1

Answer:

The fraction 7/8 x 4/5 is equivalent to 7/10 when simplified.

Given that are two fractions 7/8 and 4/5 we need to find their product.

To calculate the expression 7/8 x 4/5, you need to multiply the two fractions together.

Here's the step-by-step explanation:

Step 1: Multiply the numerators (top numbers) together:

7 x 4 = 28

Step 2: Multiply the denominators (bottom numbers) together:

8 x 5 = 40

Step 3: Write the result as a new fraction:

28/40

Step 4: Simplify the fraction (if possible) by finding the greatest common divisor (GCD) of the numerator and denominator and dividing both by the GCD:

GCD(28, 40) = 4

Divide both numerator and denominator by 4:

28 ÷ 4 = 7

40 ÷ 4 = 10

So, the final answer is 7/10.

Answer 2

Answer: To multiply fractions, all you have to do is multiply the numerator and then the denominator, and then reduce and make into mixed numbers!
7x4=28
8x5=40.
28/4=7
40/4=10

Your answer to this is 7/10!!!!! I hope this helps you!!

True or false An invalid statistical test measure may have questions that are misinterpreted.

Answers

Answer: True.

Step-by-step explanation: The motive of all statistical tests is to check whether all the variables or unknown quantities we are using in the test are independent of each other or are related among themselves.

Also, when we write an article, we should always check whether the statistical test we are using is suitable for the type of data concerned or not.

Furthermore, if a statistical test come out to be invalid, then it may be possible that there are some questions that are misinterpreted.

Thus, the answer is true.

True. An invalid statistical test measure may have questions that are misinterpreted.

Two rectangles have an area of 81 square inches. Name one possible perimeter for each rectangle. I need to show the problem please.

Answers

you would have to find to factors of 81 which could be 9 and 9.And since a rectangle is a square, the rest of the sides would be the same.Therefore, a possible perimeter is 9 times 4,which is 36.

A number x is no more than 9 units away from 8. Write and solve an absolute-value inequality to show the range of possible values of x.|x − 8| ≤ 9
−1 ≤ x ≤ 17

|x + 8| ≤ 9
−17 ≤ x ≤ 1

|x − 9| ≤ 8
1 ≤ x ≤ 17

|x + 9| ≤ 8
−17 ≤ x ≤ −1

Answers

Answer:

Option A is right

Step-by-step explanation:

Given that a number x is no more than 9 units away from 8

This implies that number can be either larger than 8 by less than 9 units or smaller than 8 by less than 9 units.

Difference between x and 8 is at most 9.

We represent in absolute value as

$|x-8|\leq 9\n-9\leq x-8\leq 9\n-1\leq x\leq 17$

Hence option A is right

The answer is a (|x - 8| ≤ 9 and -1 ≤ x ≤ 17) Because the difference between x and 8 can't be greater than 9, but it can be less than or equal to it, and because the range that x could be would be -1 to 17, since 8 + 9 = 17 and 8 - 9 = -1.

If a = 2, b = 3, and c = 1, what is the value of a + b + c? 6 2 0 4 6

Answers

If you would like to know what is the value of a + b + c, you can calculate this using the following steps:

a = 2, b = 3, c = 1
a + b + c = 2 + 3 + 1 = 6

The correct result would be 6.

The answer is 6, because you have to substitute.

What is the solution to this system of equations x-3y=-2 x+3y=16

Answers

The solution to the system of equations x - 3y = -2 and x + 3y = 16 is x = 7 and y = 3.

Here, we have,

To solve the system of equations:

Equation 1: x - 3y = -2

Equation 2: x + 3y = 16

There are multiple methods to solve this system, such as substitution or elimination.

Here, we'll use the elimination method to eliminate the variable "x":

Add the two equations together:

(x - 3y) + (x + 3y) = -2 + 16

Simplifying, we get:

2x = 14

Divide both sides of the equation by 2:

2x/2 = 14/2

Simplifying further, we have:

x = 7

Now, substitute the value of x into either of the original equations (let's use Equation 1):

x - 3y = -2

Substituting x = 7, we get:

7 - 3y = -2

Solve for y:

Subtract 7 from both sides:

-3y = -2 - 7

-3y = -9

Divide both sides by -3:

y = -9 / -3

y = 3

Therefore, the solution to the system of equations x - 3y = -2 and x + 3y = 16 is x = 7 and y = 3.

x- 3y = -2
x + 3y = 16
----------------add
2x = 14
x = 14/2
x = 7

x + 3y = 16
7 + 3y = 16
3y = 16 - 7
3y = 9
y = 9/3
y = 3

solution is : (7,3)
