The answer is A) x = 9
We know this because every four sided figure has angles that measure up to 360. So we can subtract all of the angles and then use the remaining angle to solve the problem.
360 - 90 - 90 - 99 = 81.
So with the remaining angle being 81, we can solve for x.
x^2 = 81
x = +/-9
Since +9 is the only answer that makes sense in this case, x = 9.

On the way there, 1.5x12 = 18
On the way back, 1.5x10 = 15
Answer:
-1
Step-by-step explanation:
"Gradient" is yet another term for "slope" or "rate of change." It is the ratio of "rise" to "run."
Here, the graph goes through grid intersections such that 1 to the right is 1 down. The "rise" is -1 for a "run" of 1, and the slop (gradient) is ...
m = rise/run = -1/1 = -1
The gradient of the graphed line is -1.
1x=-1
that means whererever you see x, you replace it with -1
x is a placeholder for an unknown number
so repolace it
-1+5=4
5-1=4

These are all correct. To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one. Or just use a calculator lol.
