The answer would be x less than or equal to 3
(same equality symbol you used)
Answer:
C≈157.08in
Step-by-step explanation:
C=2πr=2·π·25≈157.07963in
You would add 10.3 and 5.9 which would equal 16.2, and subtract that from 20 and change that decimal into a fraction, which would be 19/50
1. Answer x=-5
You would subtract 25 from each side of the equal sign, taking 25 away from 40 and 25 away from 25, isolating the x. So you would then have -3x=15. You would then divide each side by -3, and getting x=-5
Answer:
50
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
A + B + C = 180
2x-10 + 70+ x+30 = 180
Combine like terms
3x +90 = 180
Subtract 90 from each side
3x+90-90=180-90
3x= 90
Divide by 3
3x/3= 90/3
x=30
We want to find angle A
A = 2x-10
=2*30 -10
=60-10
50
