Answer: x=19
Step-by-step explanation: 2x+8x-10=180
Step 1: Simplify
2x+8x-10=180
2x+8x+-10=180
(2x+8x)+(-10)=180(combine like terms)
10x+-10=180
10x-10=180
Step 2: Add 10 to both sides
10x-10+10=180+10
10x=190
Step 3: Divide both sides by 10
10x/10=190/10
x=19
okay... THE ANS IS 5/35 IS THE RIGHT ONE

0.0075 ÷ (1.5 x 10^-6) = (7.5 x 10^-3) ÷ (1.5 x 10^-6) = (7.5 ÷ 1.5) x (10^(-3 - (-6))) = 5 x 10^(-3 + 6) = 5 x 10^3
Answer:
4.5
Step-by-step explanation:
There is a formula for the Intersection of chords
10*x = 9*5
here.
so.... x = 45/10 = 4.5
