y = x+4
y = 2x-5
y = x-1
<h3>Answer: x = 50</h3>
========================================
Explanation:
The angles shown are vertical angles. Any pair of vertical angles are always congruent (i.e. equal)
Set the two expressions equal to each other and solve for x.
2(x+10) = 3x-30
2x+20 = 3x-30 ... distribute
2x+20-2x = 3x-30-2x ... subtract 2x from both sides
20 = x-30
20+30 = x-30+30 ... add 30 to both sides
50 = x
x = 50
---------
Check:
Plug x = 50 into the equation. Both sides should result in the same value
2(x+10) = 3x-30
2(50+10) = 3*50-30
2(60) = 3*50-30
120 = 150-30
120 = 120
The answer is confirmed.
(4 1/5) / (3 1/8) =
(21/5) / (25/8) =
21/5 * 8/25 =
168/125 =
1 43/125 <==
If the original price is $49.99 and it is 30% off. You would want to find what 70% of 49.99 is in order to find the 30% of sale price. So once you do that you will find out that the answer is $34.99
