Answer:x=12
Step-by-step explanation:
5x+9-3x=18+15
First of all, in the case of a equation that has one vatiable having one power ,you need to bring all the variable together in one side.
5x-3x=18+15-9
0r,2x=18+6
Or,2x=24
Or,x=24/2
Or,x=12
So it's the solution..
2 hole pizzas equal 16 because 1 pizza has 8 slices so make 1/4 a decimal which is 4 4/16 equals 4 so for 4 friends 1/4 is left and do the same to the 21/3 which equals 7 so 7 +4 = half the amount to fead the friends

Answer:
12 ft
Step-by-step explanation:
Hi there!
<u>1) Find the length of the other leg in the right triangle</u>
There are two ways we can go about this. The first way is to use trigonomic ratios:
We're given one of the legs and we're trying to solve for the other, so we can use the tangent ratio:

Let x be equal to the length of the other leg. Plug in the known values:

The other way to find this is to observe the angles. Because we're given that two of the angles are 45 and 90 degrees, we know that the third angle is 45 degrees. This makes this an isosceles triangle, meaning the other leg is 7 ft long.
<u>2) Determine the height of the hoop</u>
Add 7 ft and 5 ft (the person's height):
7+5=12 ft
I hope this helps!
