Answer:Make the denominators the same

Step-by-step explanation:

find the least common denominator

As in find there least common multiple

Then multiply both numerators and denominators to find the common multipl

Example:

2/8 multiples: 8,16,24

5/6 multiples:6,12,18,24

Least common multiple is 24

So 8*3=24

2*3=6

So 2/8=6/24

6*4= 24

5*4=20

So 5/6=20/24

Then you subtract 20/24 by 6/24

Then your done:)

Hoped this helped:)

olasank [31]

Answer:

C. $cA-cB=c(A-B)$

Step-by-step explanation:

Given that A and B are matrices and $c$ is a scalar, then the distributive property of scalar multiplication over addition is given by;

$c(A+B)=cA+cB$

The distributive property of scalar multiplication over subtraction is

$c(A-B)=cA-cB$

The correct answer is C.

R+6≥11 ; {4,5,6,7}<br><br> Answer choices: 4, 5, 6,7

Alex_Xolod [135]

For this case we have the following inequality:

$r + 6 \geq11$

To solve we have:

Subtracting 6 from both sides of the equation:

$r \geq11-6\\r \geq5$

Thus, the solution is given by all values of r greater than or equal to 5.

Answer:

The solution is given by all values of r greater than or equal to 5.

The local high school is hosting the last soccer game. They charged adults, x, $5 to enter, and $3 for students, y. It costs the

Neporo4naja [7]

Answer:

(40,35)

Step-by-step explanation:

Well we can immediacy eliminate 2 options for ow becuase if you add them up they don’t equal 75 and in the equation it asked for x+y=75.

Now we just test out each x and y possibility

We know 5x+3 > 300

So lets try the first one

30 is x

45 is Y

5*30=150

45*3=135

Now if you add them

285

285 is not greater than 300 so thats wrong

SO B is correct

But lets check just in case

5*40=200

3*35= 105

305 IS greater than 300

305 > 300

SO B is correct

The point (40,35)
