Answer:
x = 17
, y = 34
Step-by-step explanation:
Since the triangle is right use trig ratios to find x and y
note exact values sin30° = 
, tan30° = 
sin30° = 
= 
multiply both sides by y
y sin30° = 17 ( divide both sides by sin30° )
y = 
= 34
tan30° = 
= 
multiply both sides by x
x tan30° = 17 ( divide both sides by tan30° )
x = 
= 17
Answer:
n = -2
Step-by-step explanation:
Eliminating parentheses, you have ...
2n +6 -6n = 14
Combining terms and subtracting 6, you get ...
-4n = 8
Dividing by the coefficient of n gives ...
n = -2
_____
<em><u>Check</u></em>
2(-2) +3(2 -2(-2)) = 14
-4 +3(2+4) = 14
-4 +3(6) = 14
-4 +18 = 14 . . . . answer checks OK
-4x+154 should be the answer
Answer:
idk if this is right but if it is right can i have brainliest and if it is wrong then rate me a 1 and you can umm... report me if u want
Step-by-step explanation:
Let's solve for x.
6x+7y=13x
Step 1: Add -13x to both sides.
6x+7y+−13x=13x+−13x
−7x+7y=0
Step 2: Add -7y to both sides.
−7x+7y+−7y=0+−7y
−7x=−7y
Step 3: Divide both sides by -7.
−7x
−7
=
−7y
−7
x=y
