As you bring all the non-variable numbers over to the right side, it becomes 384 which you then will divide the 32 in x which gives us 12. so x=12
Two equations that have the solution 5:
3y = 2y + 5
2y - y = -3 + 8
To solve an equation is to isolate a variable and find its specific value.
You can verify this by plugging the numbers into the Pythagorean theorem,
, where c is the hypotenuse (the longest side, in this case 53).
So it would be:
The equation is true.
2809 = 2809
Answer:
I think d
Step-by-step explanation:
.....................
There are two triangles: a small one to the left and a big one, which includes the small one. They both have a common angle (the leftmost angle) and since (we can assume) the two columns meet the floor at right angles, they both have two equal angles. This means they are similar (AAA).
Let the distance of the base of the stairs to the tallest column be d.
Because matching sides of similar triangles are in the same ratio,
4 / 6 = d / (6 + 12)
4 / 6 = d / 18
(4 * 18) / 6 = d
d = 12
The answer is C
