Answer: -5
Step-by-step explanation:
-3x+9y=-57 x=4
-3(4)+9y=-57
-12+9y=-57
+12
9y=-45
9y
y=-5
Answer: We are missing some data here, but it appears to be a right triangle question. Assuming that triangle ABC is a right triangle, the measure of angle B would be about 63.26 degrees.
If you draw a right triangle ABC with the given information, you will see that we have an adjacent side and hypotenuse with regard to angle B.
Therefore, we can write and solve the following cosine ratio.
cos(B) = 9/20
B = 63.26 degrees
Answer:
x = 1.33 I think.
Step-by-step explanation:
First you would write out your problem
Next you would take away 6 from both sides to get 4 = 3x
Now you would divide both sides by three to get x = 1.33
Oof I was going to answer this but it got me confusion.
