Please help! I am so confused

Mathematics

Answer:

The second option, y + 2x = 10, is the correct answer for this problem.

Step-by-step explanation:

There are many different ways to solve this problem.  I am going to pick a point represented in the table and plug its values into the given equations to find the correct response.

From the table, we can conclude that the point (0,10) must satisfy the equation.  This means that if we plug in 0 for x and 10 for y into the equations below, we should get a true statement.

y - 2x = 14

10 - 2(0) = 14

10 = 14

Since 10 is not equal to 14, we know that the first option is incorrect.

y + 2x = 10

10 + 2(0) = 10

10 = 10

Therefore, the second option may be our answer, but we should make sure the other options are incorrect.

2y + x = 23

2(10) + 0 = 23

20 = 23

Since 20 is not equal to 23, we know that the third option is incorrect.

y + x = 11

10 + 0 = 11

Since 10 is not equal to 11, we know that the fourth option is also incorrect.

Since the second option is the only answer that yielded a true statement when a point from the table was plugged in, we can conclude that the second option (y + 2x = 10) is the answer.  If you wanted to make sure, you could plug in each of the points represented in the table and confirm that they too make the equation true.

Hope this helps!

Gwar [14]
H + m = 480
h = 2m

2m + m = 480
3m = 480
m = 480/3
m = 160 <=== there were 160 math books

h = 2m
h = 2(160)
h = 320 <=== there were 320 history books

Timothy is 13 5/6 years old. Camden is 1 1/3 years younger than Timothy and Jane is 1 1/4 years younger than Camden. How old is
galina1969 [7]

Answer:

Jane is 11 1/4 years old.

Step-by-step explanation:

Subtract all of the numbers given.

13\frac{5}{6} -1\frac{1}{3} -1\frac{1}{4}.

To subtract this, we need to find a common denominator.

A common denominator in this situation is 12. To do this multiply the 5 and the 6 of 5/6 by 2. Multiply the 1 and the 3 of 1/3 by 4. And multiply the 1 and the 4 1/4 by 3.

The new expression will look like this:

13\frac{10}{12} -1\frac{4}{12} -1\frac{3}{12}.

Now we can subtract.

13\frac{10}{12} -1\frac{4}{12} -1\frac{3}{12}=11\frac{3}{12}

Reduce the answer.

11\frac{3}{12}=11\frac{1}{4}

In decimal form 11.25

Hope this helps!

If not, I am sorry.

Solve: 2x + 3 = -1<br> Please help me on this question :)
Nina [5.8K]

Answer:

<u>x=-2</u>

Step-by-step explanation:

the while goal of this is to isolate the x on one sideso x= the answer, so

first you would want to take the 3 and subtract it from both sides giving you 2x=-4 and then you would divide the 2 to further isolate the x giving you <u>x=-2.</u>
