Answer:

Then the solution is (4, 6).

Step-by-step explanation:

Let's use the substitution method:

First multiply the second equation by 4, obtaining 4y = -2x + 32.

Now substitute (-2x + 32) for 4y in the first equation:

3x + (-2x + 32) = 36, or

3x - 2x + 32 = 36. or

x = 4.

If x = 4, then the second equation yields y = (-1/2)(4) + 8, or

y = -2 + 8, or y = 6

Then the solution is (4, 6).

Check, using the first equation:

Does 3(4) + 4(6) = 36?  Does 12 + 24 = 36?  YES

On a scale drawing inch = 1 foot. What are the dimensions on the scale for a room that is 27 feet by 20 feet?
Rufina [12.5K]
If 1 inch = 1 foot then 1 foot = 1 inch.
With this, you can make a ratio of 1 foot:1 inch, or 1:1.
Starting with the first dimension, 27 feet, just change the 1 to 27 in the ratio.
27:?
To find how many inches this is in the scale drawing, find how much 1 had to be multiplied by to get to 27. This is 27, since anything times 1 is itself.
Just multiply the other side by 27 as well to get the answer for the first dimension.
1 • 27 = 27
So 27 feet = 27 inches in the scale drawing.
Now do the same for the second dimension.
1:1
20:?
1 • 20 = 20
20:20
The answer is that the scale drawing has dimensions of 27 inches by 20 inches if 1 inch = 1 foot is the scale

X-3y=-24<br> 5x+8y=-5<br><br> this equation is substitution, need help :))
Leto [7]

Answer:

x=-9, y=5. (-9, 5).

Step-by-step explanation:

x-3y=-24

5x+8y=-5

--------------

x=-24+3y

5(-24+3y)+8y=-5

-120+15y+8y=-5

-120+23y=-5

23y=-5-(-120)

23y=-5+120

23y=115

y=115/23

y=5

x-3(5)=-24

x-15=-24

x=-24+15

x=-9

If you roll a six-sided die, what is the probability that you will obtain a number greater than2?
Citrus2011 [14]

Answer:

c  2/3

Step-by-step explanation:

there are six sides to a die.  Therefore when you roll you have a 1 in 6 of getting a specific number 1/6 .  Since you only want numbers greater than 2 your odds are now 4/6.   Remove 1 and 2 from the equation and there are now only 4 out of 6 correct numbers.  4/6

4/6 can be reduce to 2/3rds.  That is your answer
