Use the Pythagorean theorem (a^2+b^2+x^2)
4:5
explanation-
Express the given ratios as fraction
4 : 5 = 4/5 and 2 : 3 =2/3
Now find the L.C.M (least common multiple) of 5 and 3
The L.C.M (least common multiple) of 5 and 3 is 15.
Making the denominator of each fraction equal to 15, we have
4/5 = (4 ×3)/(5 ×3) = 12/15 and 2/3 = (2 ×5)/(3 ×5) = 10/15
Clearly, 12 > 10
Now, 12/15 > 10/15
Therefore, 4 : 5 > 2 : 3.
Now it would be
-2.3+(-5.9)
now just add those two together
and u get -8.2
So the answer is A
Answer:
<em>Mark used 6.43 megabytes of data.</em>
Step-by-step explanation:
The given equation is:
, where
is amount of data used in megabyte.
For finding the amount of data Mark used, <u>we need to solve the above equation for
</u>.
First subtracting 5.25 from both sides, we will get.....
Now, dividing both sides by 0.3 ...........

<em>(Rounded to the nearest hundredth)</em>
Thus, Mark used 6.43 megabytes of data.
Answer:
4
Step-by-step explanation:
Lets make
be the ? in the equation.
That becomes (
x 3) - 3 = 15.
First you have to add 3 on both sides. After doing that it gets to (
x 3) = 15 - 3.
Then you simplify it to 3
= 12.
Now you divide 3 on both sides. That gets to
= 4 after doing it.
