Answer:
120
Step-by-step explanation:
As x goes from 1 to 2, y increases by 4 from 4 to 8
As x goes from 2 to 3, y increases by 4 from 8 to 12
We increase by 4 each time
The formula for an arithmetic sequence is
an = a1+d(n-1)
where a1 is the first term which is 4
d is the common difference or the number we add each time which is 4
n is the term we are looking for which is 30
a30 = 4 +4 (30-1)
a30 = 4+4(29)
= 4+116
= 120
Answer:
y = 23
x = 28
Step-by-step explanation:
Find y first.
3y + 5y - 4 = 180 The two angles are supplementary if the all the lines are parallel. Combine the left side.
8y - 4 = 180 Add 4 to both sides
8y - 4 + 4 = 180 + 4
8y = 184 Divide both sides by 8
y = 23
====================================
Now if the lines are parallel, then 3y = 2x + 13
But we already know y
3*23 = 2x + 13 Do the multiplication
69 = 2x + 13 Subtract 13
56 = 2x Divide by 2
x = 56/2
x = 28

<em>Heyy there, it's Avery. And I'm here to help! :)
</em>----------------------------------------------------------------------------------------------------------[<The Explanation>]:
Let x= number of watches sold
<em>Ethan= x(14) + (20)(1.50)</em>
<em>Roy = x(13.50) + (20)(1.80)</em>
Since they collected the same amount of money:
<em>14x + (20)(1.50) = 13.50x + (20)(1.80)</em>
Combine like terms:
<em>14x - 13.50x = (20)(1.80) - (20)(1.50)</em>
<em>0.50x = 36 - 30</em>
<em>0.50x = 6</em>
<em>x = 6/0.50</em>
<em>x= 12</em>
Ethan sold 12 watches. And also Roy.
Andddd...We're done! :D
