It all depends on the math question but usually you solve for x, then check it. Plug x back in and see if it works. But it all depends on the math problem
We can write this in math as x+y+z=104, x=y-6, and z=3y
Because we already know what x and z are in terms of y, we can substitute our values for x and z into the first equation. This now looks like (y-6) + y + (3y) = 104. Now we can simplify our equation to find our value for y.
y-6 + y + 3y = 104 simplifies to 5y - 6 = 104, then 5y=110, and finally y=22.
Now that we know our value for y we can find our values for x and z by substituting our value for y into the other two equations.
The second equation x = y-6 can be simplified as x = 22 - 6 and further simplified as x = 16.
The third equation z = 3y can be written as z = 3(22) or z = 66.
Our three numbers are 16, 22, and 66. Hope this helps you!
It’s 100°! I cause 75+75 = 150 and if the circle is 350 then 150-350 = 200 and 200÷2 is 100
So we want to see which number line shows the sum 1.5 + 2.5. We will see that the correct option is <u>"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"</u>
So the number line usually starts at 0 and goes to the first number, 1.5 in this case.
Then, it moves accordingly to the second number, 2.5 (so it will move 2.5 units to the right)
So the number line should start at 0 and move to the right until it meets 1.5 + 2.5 = 4.
From the options, the only that is correct is:
<u><em>"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"</em></u>
