$518.5 = $375 + $41x
Now that we have our equation, let's solve for the # of hours
Subtract $375 from both sides
$143.5 = $41x
Divide both sides by $41
3.5 = x
The number of labor hours was 3.5
Answer:
19
Step-by-step explanation:
If Catriona has 16 more stickers than Peter than the only thing you have to do is subtract and find the difference
Solution :
First term, a₀ = -10 .
Common difference of A.P. , d = -8 - (-10) = 2 .
Last term, aₙ = 24 .
We know, last term is given by :
aₙ = a₀ + (n-1)d
24 = -10 + (n-1)×2
2n - 2 = 34
n = 18
Now, sum of series is given by :
Hence, this is the required solution.
Answer: 3x^4+7x^3+7x^2+11x+4
Step-by-step explanation:
(x^2+3x+4)(3x^2-2x+1)
3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4
Collect like terms
3x^4-2x^3+9x^3+x^2-6x^2+12x^2+3x+8x+4
3x^4+7x^3+7x^2+11x+4
