B
-2 1/4 = -9/4
(-9/4)/(-2/3)
150 % of 200
150 / 100 = 1.5
1.5 * 200 = 300
hope this helps!.
The answer is (4x+3y=4 2x-7=7: 5/2 and y=-2) hope it helps and have a good day!
2, –6 is the correct answer
You have to go at this in a round-about fashion...by finding the length of the leg across from the 67 degree angle. This is found by using the tangent ratio...Tan(67)=x/137; x=137tan(67) = 322.8. Now you can use this in one of two ways: use Pythagorean's Theorem to find the length of the hypotenuse OR you could use the sin67=322.8/x. Up to you. Either way, make sure you have your calculator in degree mode!
