Since y varies inversely as x , the equation is y=k/x....... Then you plug in 2 for y and 25 for x to find K....... After that you get K= 50...... Then plug in 50 for K and 40 for y then solve for x....... After that you get X= 1.25

11/12 - 7/8 in fraction pls help
hjlf

Answer:

1/24

Step-by-step explanation:

We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.

So we multiply 11 by 8, and get 88.Then we multiply 7 by 12, and get 84.

Next we give both terms new denominators -- 12 × 8 = 96.

So now our fractions look like this:

88 /96 -84 /96

Step 2

Since our denominators match, we can subtract the numerators.

88 − 84 = 4

So the answer is:

4 /96

Step 3

Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

To find out, we try dividing it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:            

4 /96 ÷ 2 =2 /48

Let's try dividing by 2 again...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

2 /48 ÷ 2 =1 /24

Let's try dividing by 2 again...

No good. 2 is larger than 1. So we're done reducing.                                    There you have it! The final answer is:

11 /12 -7 /8=1 /24

Given the following diagram, find the missing measure.
Murljashka [212]

Answer:

Measure of ∠P = 60°

Step-by-step explanation:

Consider triangle PMO.

Since PM is perpendicular to MO , hence m∠PMO = 90°

Also given that m∠MOP = m∠2 = 30°

And since sum of three angles of a triangle is 180°

⇒ m∠PMO + m∠MOP + m∠MPO = 180°

⇒m∠MPO = 180° - (m∠PMO + m∠MOP) = 180° - ( 90 + 30 ) = 60°

Hence m∠MPO that is m∠P is 60°
