Answer:
0.75(3/4) part of the room
Step-by-step explanation:
if he takes 2/3 hours to paint 0.5 room
then he will take 1 hour to paint x
cross multiply we have
x= 0.5/2/3
x=0.5*3/2
x= 1.5/2
x=0.75 part of the room
75/100= 15/20=3/4 part

The tree diagram shows the sample space of two-digit numbers that can be created using the digits 9,2 1, and 8. What is the probability of choosing a number from the sample space that contains both 2 and 8?
Answers
Answer:
Given : the sample space of two-digit numbers that can be created using the digits 9,7,1, and 8.
To Find : probability of choosing a number from the sample space that contains both 7 and 8.
Solution:
TREE DIAGRAM
9 7 1 8
↓ ↓ ↓ ↓
------------------- ---------------- ----------------- ---------------
↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓
9 7 1 8 9 7 1 8 9 7 1 8 9 7 1 8
Total Sample space = 16
Contains both 7 and 8
is ( 7 , 8) or ( 8 , 7)
Hence probability of choosing a number from the sample space that contains both 7 and 8. = 2/16
= 1/8
= 12.5 %

Which of these systems of equations would be best solved using the subtraction method?
I. 2x−7y+3y = 4 −6x−4y = −52
II. 2y = −5x+6x−5 y = 2x−6
III. −7x+3x+2y = 4 4x−6y = −52
Answers
Answer:
Step-by-step explanation:
1. x+2y=6 or x=6-2y
3x-2y=2
3(6-2y)-2y=2
18-6y-2y=2
18-8y=2
-8y=-18+2
-8y=-16
y=-16/-8
y=2 ans.
x+2*2=6
x+4=6
x=6-4=2 ans.
Proof:
3*2-2*2=2
6-4=2
2=2
I leave the rest for you to practice with.
3. 4x+y=7
2x+5y=-1
5. 3x+2y=-2
6x-y=6

7. -3x+3y=3

---------------------------------
4y=12
y=12/4
y=3 ans.
3x+3=9
3x=9-3
3x=6
x=6/3
x=2 ans.
Proof:
-3*2+3*3=3
-6+9=3
3=3
I'll leave the rest for practice.
9. -5x+12y=20

Answers
27 + 6*3 + 5
27+ 18 + 5
The answer is 50
Answer:
50
Step-by-step explanation:
If x=3 then x^3 would be 3 with the exponent of 3. It would look like 3x3x3=27
6x would be 6 times 3 which is 18.
Then you have just an extra 5.
Then add them all together. 27+18+5=50.
Therefore, your answer is 50.

x. Explain who is correct.
Answers
Answer:
If we let x be the number of ticket sold and y be the amount in dollars donated then, the equation would be,
x = 2y
We can check our answer by substituting the given,
10 = 2(5)
10 = 10
The equation can also be written as,
y = (1/2)x
Student B is correct.
Answer:
Sample Response/Explanation: The point that represents what the local business will donate is (10, 5). After testing the point in both equations, you can see that student B wrote the correct equation; 5 = 12(10).

B. In the boys' long jump, Kevin jumped a distance of (6x1) + (9x 1/10) + (8x1/100)+(3x1/1000) meters. Leon jumped a distance of 6.093 meters. Kevin said he jumped farther than Leon. Is Kevin correct? Explain why or why not.
Answers
Next...
1/10 = 10% which equals 0.1
0.1 * 9 = 0.9
Now...
1/100 =1% which equals 0.01
So that means that 0.01 * 8 = 0.08
Lastly... 0.0010 * 3 = 0.003
You add
6 + 0.10 + 0.08 + 0.003 and you get 6.183.... (Kevin’s distance) which is obviously a farther distance than 6.093.
Kevin is correct :)
