Answer:
- 57
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a + (n - 1)d
where a is the first term and d the common difference
Here a = 13 and d = - 2.5, thus
= 13 + (28 × - 2.5) = 13 - 70 = - 57
The answer will be:
2x+x=45
4x=45+x
3(1/3x)=15
ETC. Hope it help!
Answer:
It represents the one-time campaign fee 500.
Step-by-step explanation:
A company is paying a local television station to run its commercials. The cost of running commercials is a one-time campaign fee and also a per-second fee for the air time of each commercial. The cost can be modeled by the equation y = 500 + 50x, where x is seconds.
The equation is in the slope-intercept form and the y-intercept is 500.
Now, it represents the one-time campaign fee 500. (Answer)
In this problem, you have already shown the solution.
24 = 3y - 6 => 30 = 3y, y =10
12 = 5x + 2 => 10 = 5x , x = 2
And yes, basically parallel sides must have the same length
These are the answers:
for 17.) x = 2
y = 10
for 18.) mid segment = (side 1 + side 2) / 2 -->
19 = (24 + side2) / 2 -->
38 = 24 + side2,
thus, side 2 = 14 units
