Answer:
x = 12
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
3x+19 + 5x = 115
Combine like terms
8x + 19 = 115
Subtract 19 from each side
8x+19 -19 = 115 -19
8x = 96
Divide each side by 8
8x/8 = 96/8
x =12
Answer:
a. 84 < n + (n + 2) + (n + 4) < 96
b. 26 < n < 30
Step-by-step explanation:
Let n = 1st number
n+2 2nd even number
n+4 = 3rd even number
The sum of these 3 numbers is
n+n+2+n+4
It must be between 84 and 96 (it does not include this 84 and 96)
84< n+n+2+n+4 < 96
Now we need to solve this
Combine like terms
84 < 3n +6< 96
Subtract 6 from all sides
84 -6 < 3n+6-6 < 96 -6
78 < 3n < 90
Divide all sides by 3
78/3 < 3n/3 < 90/3
26 < n< 30
Answer:
If my calculations are correct.
Step-by-step explanation:
Answer:
1 / y^7
Step-by-step explanation:
Y^-9•y^-8•y^10
= y^10 / y^9•y^8
= y^10 / y^17
= 1 / y^7
0.17
yuh this is correct lol
