HCF(320, x) = 20, LCM(320, x) = 2240, then x =

HACTEHA [7]4 years ago

Answer:

  140

Step-by-step explanation:

When working HCF and LCM problems, I like to think in terms of this little diagram:

  (a [ b ) c]

It shows me one of the numbers is ab, the other is bc, the HCF is b and the LCM is abc. "a" and "c" must be relatively prime for "b" to be the HCF.

__

Here, we're given ...

  b = 20

  ab = 320

  abc = 2240

Then ...

  c = abc/(ab) = 2240/320 = 7

  x = bc = 20(7) . . . . . . equivalently, x = (abc·b)/(ab) = (2240·20)/320

  x = 140

If p is a true statement and q is false, then pv g is true.<br> True<br> False
forsale [732]

If you meant to say p \vee q, then that statement is true.

This is a disjunction which is an "or" statement. If either p or q is true, then overall p \vee q is true. So the only time it's false is when both p and q are false together.

<h3>Answer: True</h3>

Y=3.2x+5 how do you put that in a table
Setler [38]

Answer:

Step-by-step explanation:

y = 3.2x+5

This equation represents a straight line where 3.2 is the slope of the line and 5 is the intercept of the line on the y-axis (basically where the line touches the y-axis)

So,because this is a line you only need two points to draw it.

One point you already know it's y =5.

To find another point that lies on the line just substitute a convenient number for x.For example say if x= 1/3.2

y = 3.2*( 1/3.2) +5

Therefore:

y = 1+5 =6

So,the other point on the line is (1/3.2 , 6)

Now find the points y = 5 and (1/3.2 , 6) on the xy plane and draw the line passing through them.
