Answer:

Step-by-step explanation:

Hi!

So first we do the parenthesis

( $5\frac{3}{4}$ - $1 \frac{5}{6}$ ) =

Since 4 and 6 ≠ (does not equal to)

We change 4 and 6 to a number they have in common so, that number is 12 which is the lcm (least common factor). We are going to multiply 3 for each number (3 and 4) and 2 for 5 and 6, so

3/4 x 3 = 9/12 = 5 9/12

5/6 x 2 = 10/12 = 1 10/12

Now we substract,

5 9/12

- 1 10/12

_________

4 1/12

now that we have this answer we will substract 4 1/12 from 10 which would be

5 11/12

hope this helped!! Good luck! Brainliest? :) <3

The solution system to 3y-2x=-9 and y=-2x+5

Alecsey [184]

Answer:

$\boxed{(3,-1)}$

Step-by-step explanation:

Hey there!

Well to find the solution the the given system,

3y - 2x = -9

y = -2x + 5

So to find x lets plug in -2x + 5 for y in 3y - 2x = -9.

3(-2x + 5) - 2x = -9

Distribute

-6x + 15 - 2x = -9

-8x + 15 = -9

-15 to both sides

-8x = -24

Divide -8 to both sides

x = 3

Now that we have x which is 3, we can plug in 3 for x in y = -2x + 5.

y = -2(3) + 5

y = -6 + 5

y = -1

So the solution is (3,-1).

Hope this helps :)

property of real numbers that states that the order in which numbers are added or multiplied dose not change the value

timurjin [86]

Answer:

"Commutative property of addition and of multiplication"

Step-by-step explanation:

This is the "commutative property" of addition and of multiplication. That as its name indicates tells us for additions, that if we add A + B, or B + A, we should get the same result. Similarly, the "commutative property" of multiplication tells us that if we perform the product A * B we should get the same answer as if we perform the product: B * A.

Ali finished his history assignment in 1/4

Lina20 [59]

Hello there!

For this you simply need to give both fractions a common denominator!

The easiest way to do this specific problem would be to make the denominator 12. Why 12? Because 4 x 3 = 12.

So:

1/4 --> ?/12 --> 1 (3) / 12 --> 3/12

2/3 --> ?/12 --> 2 (4) / 12 --> 8/12

Total amount of time means the sum (adding them together).

When adding fractions, you MUST have a common denominator! (Which is what we just did).

So 3/12 + 8/12 = (8+3) / 12 = 11/12 hours

Notice how the denominator stayed the same? When adding/subtracting fractions, the denominator stays the same! :)

Hope this helped!
