3(x-6)
it says too expand and simplify it plz help

Answers

Answer 1

Answer:

3x-18

Step-by-step explanation:

To expand this you must use the distributive property to distribute the 3. Using this property you can multiply the x and -6 by 3. So the expanded equation would first look like x*3 + -6*3. Then simplify to get 3x-18.

Answer 2

Answer:

3x-18 expanded

Step-by-step explanation:

x-6 simplified

use the distributive property to expand the expression

3*x= 3x

3*-6=-18

to simplify,

find the GCF and solve

gcf= 3

3x/3=1x or just x

-18/3=-6

hope this helps

Solve the system of equations using elimination.
3x-2y=5
x+2y=3

Answers

Answer:

x = 2

y = 1/2

Step-by-step explanation:

3x - 2y = 5

x + 2y = 3

We don't have to mutiply anything because we have values that we can eliminate.-2y and 2y can be crossed off becuase they have the same value and plus and minus cancel out. We can add instead of changing the signs.

4x = 8

x = 2

Now we know that x = 2. To find y we have to plug in x into one of the equations. I am going to use x + 2y = 3.

2 + 2y = 3

2y = 1

y = 1/2

Now we figured out y. I hope I helped!

Answer:

x = 5 22/24 OR x =  5 11/12

Step-by-step explanation:

x - 3/4 = 5 1/6

To solve this we mush use inverse operations

x - 3/4 + 3/4 = 5 1/6 + 3/4

x = 5 22/24

x = 5 11/12

To add the fractions there has to be a common denominator.

1/6 x 4/4 = 4/24

3/4 x 6/6 = 18/24

Keep denominators the same and add the numerators.

If your teacher wants the answer not simplified the answer is

x = 5 22/24

If your teacher wants it simplified the answer is

x = 5 11/12

I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Bianca set the thermostat in her house to 87°F, which was 13° warmer than the temperature outside. What temperature was it outside?

Confused.

Answers

Answer: 74 degrees Fahrenheit  

Step-by-step explanation: the temperature outside was 13 degrees lower than 87 degrees, so  87 - 13 = 74

Answer:

74 degrees F

Step-by-step explanation:

Subtract the 87 - 13

This is because there are +13 degrees more than outside. So if you add 74 + 13 that were added by the thermostat, you get 87 degrees. Does it make sense?

Just subtract :)

Solve the system of linear equations by substitution.

sub 2x+16 for y into the 1st line so
1/2x+2x+16=-4 now find x
which is x=8 not plug in -8 for x, does not matter which one
you will get y=0
answer•
x=-8
y=0
(-8,0)

Answer:

y = 0

x = -8

Step-by-step explanation:

1/2x + y = - 4

y = 2x + 16

1/2x + (2x + 16) = - 4

1/2x + 2x = - 4 - 16

5/2x = -20

2/5 x 5/2x = -20 x 2/5

x = -40/5

x = -8

y = 2x + 16

y = 2(-8) + 16

y = -16 + 16

y = 0

Check:

1/2x + y = - 4

y = 2x + 16

1/2(-8) + (0) = -4

-4 + 0 = -4

-4 = -4

y = 2x + 16

(0) = 2(-8) + 16

0 = -16 + 16

0 = 0
