Answer: C
Explanation: tan = opposite/adjacent. 8 is the opposite length from angle B and 15 is the adjacent length from angle B. so tan(B) = 8/15
<span>y=3x
2. x=-y
2x+y=-2
3. 2x+2y=4
x=10-3y
4. y=7-x
2x+3y=-1</span>
Answer:
Step-by-step explanation:
2x-3= 12
+3 +3
2x = 15
/2 /2
x= 7.5
-7t-3t would be -4t
4 is less than or equal to -4t
Divide 4from -4
-1 is less than or equal to t
Answer:
Y x 3 - 3 = Y + 57
30 would be your answer
add 3 to both sides so it becomes Y x 3 = Y + 60 and 60/2=30
30 x 3 = 90-3=87
30 + 57 = 87
Hope this helps (I am twelve and I know how to do this)
