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.
Answer:
2, 6, 10, 14
Step-by-step explanation:
For the first term, T1
n = 1
4n - 2 = 4 * 1 - 2
= 4 - 2
= 2
Second term, T2
n = 2
4*2 - 2
= 8 - 2
= 6
Third term T3
n = 3
4*3 - 2
12 - 2
= 10
Forth term T4
n = 4
4*4 - 2
= 16 - 2
= 14
Hence, the first four terms are 2, 6, 10, 14
Answer:
x= 1.125
Step-by-step explanation:
first we want to get the variable by itself so divide
just divide 45 by 40
Add all the numbers in the list then divide it by how many numbers are in that list. Ex. 5,8,1,4 Would be: 5+8+1+4= 18 divided by 4 which is 4.5
