= 3/4 * 6/7. 2 into 4 is 2 and 2 into 6 is 3.
= 3/2 * 3/7 No other number can divide, so we multiply out.
=9/14

That's the answer.

I need to change the subject to x

tiny-mole [99]

(x - 4y) / w = 9

Multiply both sides by w

x - 4y = 9w

Add 4y to both sides

Help Fast Please!!!!!!!!! How can you tell if three positive numbers form a Pythagorean triple?

Fiesta28 [93]

Answer/Step-by-step explanation:

Square all three numbers. If the largest number squared is equal to the sum of the squares of the other two, then the numbers form a Pythagorean triple.

or

Since a Pythagorean triple is three positive integers a, b, and c such that (a^2)+(b^2)=(c^2), first take the sum of the squares of the two legs and make an estimate. For example, 3, 4, and 5 is a Pythagorean triple since 9+16=25

either one works

32 people volunteers to donate blood. n dident have he health requirment so they couldent donate the rest of the volunteers dona

Vesna [10]

Answer:

the equation representing total amount of blood donated is $470(32-n)=15040-470n \ ml$ .

Step-by-step explanation:

Total number of volunteers = 32

number of volunteers couldn't donate blood = $n$ .

So Number of volunteers who donated blood can be calculated by subtracting number of volunteers couldn't donate blood from Total number of volunteers.

Framing in equation form we get;

So, the number of remaining volunteers who donated blood = $32-n$ .

Each of these volunteers donated blood = 470 ml

Now Total Amount of Blood donated is equal to Amount each of these volunteers donated blood times the number of volunteers who donated blood.

Framing in the equation form we get;

total amount of blood donated milliliters = $470(32-n)=15040-470n \ ml$

Hence the equation representing total amount of blood donated is $470(32-n)=15040-470n \ ml$ .
