To find x:
Subtract 10 on both sides.
10 + 2x = 90
-10 -10
Divide 2 on both sides.
2x = 80
--- ---
2 2
This would get x alone.
x = 40
Check:
10 + 2(40) = 90
10 + 80 = 90
90 = 90
The value of x is 40. The angle degree of it is 80 when you multiply 2 by 40.
Answer:
5 1/4
Step-by-step explanation:
-2 1/4 • (-2 1/3) (convert both into improper fractions)
= (-9/4) • (-7/3)
= (9/4) • (7/3)
= (9x7) / (4x3)
= (63) / (12)
= 5 1/4
