Answer:
6 x + 23 y < $ 680 represents the combinations of x balls and y nets that can be purchased.
Step-by-step explanation:
The number of balls than can be purchased = x
The number of nets than can be purchased = y
Total savings = $ 680
Now, the cost of 1 ball =$6
So, the cost of x balls = x ( cost of 1 ball) = x ( $6) = 6 x
Also, the cost of 1 net =$23
So, the cost of y nets = y ( cost of 1 net = y ( $23) = 23 y
So, the total amount spent on x balls and y nets
= Amount spent on x balls + Amount on y nets
= 6 x + 23 y
Also, the saved amount is $680
⇒<u> 6 x + 23 y < $ 680</u>
Hence, 6 x + 23 y < $ 680 represents the combinations of x balls and y nets that can be purchased.
To find the same value as 3 x 1/10 you first have to solve 3 x 1/10
so how to do this is you have to make 3 into a fraction
so to make 3 into a fraction you can put 3 as the numerator and 1 as the denominator
so you multiply
so 3/10 has the same value as 3x1/10

Step-by-step explanation:
Answer:
I believe the answer is 9
Step-by-step explanation:
The most balloons she has is 180 and she can make 20 animals with that so 180/20=9
1. 8c^2-26c+15= (4c-3) (2c-5). Break the expression into groups: =(8c^2-6c)+(-20c+15). Factor out 8c^2-6c: 2c(4c-3). Factor out -5 from -20c+ 15: -5(4c-3). Lastly factor out common term (4c-3) and thats how you'll get your answer (4c-3) (2c-5).
2. common factors for 270 and 360 is 90.To find this write the factors of each and find the largest one.270: 1, 270, 2, 135, 3, 90, 5, 54, 6, 45, 9, 30, 10, 27, 15, 18360: 1, 360, 2, 180, 3, 120, 4, 90, 5, 72, 6, 60, 8, 45, 9, 40, 10, 36, 12, 30, 15, 24, 18, 20
3. The factors for 8 a3b2 and 12 ab4 is 4. because 8: 1, 2, 4, 812: 1, 2, 3, 4, 6, 12.
4. 81a^2+36a+4= (9a+2)^2. Break down the expression into groups: (81a^2+18a)+(18a+4). Factor out 9a from 81a^2 +18a: 9a(9a+2). Factor out 2 from 18a+4: 2(9a+2). so the groups you got are now 9a(9a+2)+2(9a+2). Lastley factor out common term (9a+2) to get (9a+2) (9a+2). Finally you get the answer (9a+2)^2.
5. mn-15+3m-5n= (n+3)(m-5). factor out m from nm+3m: m(n+3). Factor out -5 from -5n-15: -5(n+3). And thats how you get the number (n+3)(m-5)
Hope this helped :) Have a great day
