First thing First. You must find have a common denominator. If you want to find it then you do this
3: 3 6 9 12 15 18 21
7: 7 14 21 28
Once you found a number they have in common (21) You do this next
3/7 * 3/3 = 9/21
2/3 * 7/7 = 14/21
Now the next thing you do is subtract your numerators but not the denominators
14-9=5
5/12
you cant simplified so your done! Hope this helps!!!! <span />
Answer:
not a function
Step-by-step explanation:
This is not a function. For the value x =2 there are two different y values
To be a function each value of x has only one value for y
This would also fail the vertical line test
Starter info: They bought 5 T-shirts total and $20 worth of sandals. They spent $120 total.
First you subtract the sandal cost from the total price (120-20=100), then you divide the amount of t-shirts (5) by that amount (100). So 100/5=20 so that is the price of the individual T-shirts.
Final answer: $20 per t-shirt

Step-by-step explanation:
Consider triangles BXY and AZY. In these triangles:
- given;
- given;
as right angles by reflective property.
Hence,
by ASA postulate (or by LA postulate).
Congruent triangles have congruent corresponding sides, so

Answer:
8931
Step-by-step explanation:
