Answer:
Okay you have isolate a variable. As long as you perform the some operation on both sides the equations holds true. So I'll multiply the bottom one by three. 3x - 3y = 27. Now if I add the equations together I get 5x is 35 or x is 7. Then plug it back into either equation. 7 minus what is 9? -2. Y is -2
To evaluate for tan 5x/4 we proceed as follows
5x/4
=5/4*150
=225
which is in quadrant III.
This implies that the value of tan will be positive, hence:
tan 225=tan (270-225)
tan 225=tan 45
using right angle with length of the legs being unit, then
tan 45=1
hence
tan 5x/4=1
Answer:
15.49
Step-by-step explanation:
circumference= 2πr
:. 97.34= 2πr
r=97.34 ÷2π
r = 15.49
If we do 3 + 7 the first one it would 10 and the other one is also 10 so if we add 10+10 is would equal to 20 and if we do 20 x 5 it would 100. Your answer would be 100
