Step-by-step explanation:
First term(a) = 1
Common difference(d)=2-1=1
No.of term(n)=50
Sn=n÷2(n+1)=50÷2(50+1)=1275
Answer: He'd have to work 15 days.
Step-by-step explanation
With the money in his bank account he'd have to get $173 to be able to pay for the rest of the board. If you were to divide 173 by 12 you'd get 14.4166666667. But you can't have a decimal so you'd round up to get a total of 180. Which is how you get the answer of him needing to work for 15 days.
Answer:
-7
Step-by-step explanation:
First, we need to substitute x in as 14 since that is what x is equal to.
1. x / y => 14 / y
Next, we need to substitute y in as -2 since that is what y is equal to.
2. 14 / y => 14 / -2
Now to solve it;
3. 14 / -2 => -7
So now we now that x / y equals -7 when x = 14 and y = -2.

Step-by-step explanation:
Note the number 5 is repeated 4 times, hence we can say that the expression 5⋅5⋅5⋅5 is equivalent to 5 raised to the power of 4 or

Answer:
y = 1/2x
Step-by-step explanation:
y-intercept is (0, 0)
pick any point, let's say (-4, -1). Let's apply rise over run, rise up 2 points then run 4 points over to arrive at (4, 1). So, your slope is 2/4 which simplify to 1/2.
Equation of line:
y = mx + b
m is your slope
b is y-intercept
y = 1/2x + 0 same as y = 1/2x
