Answer:
n = -2
Step-by-step explanation:
Step 1: Write equation
3 = -1.5n
Step 2: Divide both sides by -1.5
n = -2
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
3 = -1.5(-2)
3 = 3
Answer:
x=22
Step-by-step explanation:
angle RTS = 5x-40 (isosceles triangle)
angle RTS + angle STU = 180 (straight line)
so 5x-40+5x = 180
10x = 220
x=22
