Answer:
x = 30 degrees
Step-by-step explanation:
Since the lines are parallel, these angles can be seen as vertical angles, which are always the same as their opposite. Therefore,
75 = 2x + 15
To solve this, you would subtract 15 from both sides, getting you closer to finding x.
75 = 2x + 15
-15 - 15
60 = 2x
Lastly, you would divide both sides to get your value for x.
60 = 2x
/2 /2
30 = x
If y varies inversely with x:
y = k / x
0.2 = k / 2
k = 2 * 0.2
k = 0.4
Answer:
The equation for the inverse variation is:
y = 0.4 / x
Answer:
3 1/2 = 7/2
3 1/8 = 25/8
7/2 x 4 = 28/8
7/2 (3 1/2) < 25/8 (3 1/8)
Therefore, 3 1/8 is greater than 3 1/2
Step-by-step explanation:
If he gets 25% of his sales, and he makes $175, that means $175 is it 25% of his sales.
So walked 4/5 mile in a 4/9 h so just use the rule of 3 simple
60 minutes ------ 1 hour
x min. ----------- 4/9 h
--------------------------------
x = 4/9 *60/1 = 240/9 = 26,6 min.
4/5 mile -------in 26,6 min.
1 mile -------- x min.
-----------------------------
x = 1*26,6/(4/5) = 26,6 /(0,8) = 33,25 min.
1 mile ..... 33,25 min.
x miles ----- 60 min.
---------------------------
x = 60/33,25 = 1,8 miles
so their unit rate in miles per hour will be 1,8 miles / hour
hope this will help you.
