Answer:
Step-by-step explanation:
9+33-6)/6-3
42-6)/6-3
36/6-3
6-3
3 to the second power is 9
because three times three is 9
Reason 1
Given
Statement 2
4x=8(x-2)
4x = 8x - 16
4x - 8x = - 16
-4x = - 16
Reason 3
Combine like terms.
Reason 4
Divide both sides by the coefficient of x.
X is equal to 4
Because RS + ST=RT
So basically x+3x=5x-4
4x=5x-4
-4x -4x
-1x=-4
x=4
He worked an 8 hour day 3 days.
Let x be the number of 8 hour days he works. Then 10-x is the number of 6 hour days he works.
8x + 6(10-x) = 66
Using the distributive property,
8x + 6*10 - 6*x = 66
8x + 60 - 6x = 66
Combining like terms,
2x + 60 = 66
Subtract 60 from both sides:
2x + 60 - 60 = 66 - 60
2x = 6
Divide both sides by 2:
2x/2 = 6/2
x = 3
There were 3 days he worked 8 hours.
<u>Answer:</u> 5
<u>Reasoning:</u> You were born 7 years ago making you 7, now subtracting 2 from that age will result in 5.
7-2=5!
