Step-by-step explanation:
-2/3 * 5 1/6 .....step 1.....correct
(-2/3 * 5) + (-2/3 * 1/6).....his error is here...it should be like I have written it, but Calvin is getting his addition and multiplication mixed up
-10/3 + (-1/9) =
-30/9 - 1/9 =
-31/9 =
- 3 4/9
Answer:
(5a - 8) + (2a² + 2a − 1) = 2a² + 7a - 9 - <u>correct.</u>
Step-by-step explanation:
(5a - 8) + (2a² + 2a − 1) = 2a² + 7a - 9 - <u>correct;</u>
(6² +6b-4) (3b +6²) = 26² +36-4 - incorrect (correct is: 18b²+...36²);
(9c-4c²) - (2c² + c) = -6c² + 10c - incorrect (correct is: -6c² + 8c).
Answer:
= -1/2
Step-by-step explanation:
Pick two points
(1,0) and (3,-1)
Then use the slope formula
m = (y2-y1)/(x2-x1)
= (-1 -0)/(3-1)
= -1 /2
Answer:
4n - 10
Step-by-step explanation:
Jay: n tickets
Pillar: 3n tickets
Jay + Pillar = n + 3n = 4n tickets
Now, Jay and Pillar together sold 10 more tickets than Amie, which means, in reverse, Amie sold 10 less tickets than Jay and Pillar together, so the expression for the number of tickets sold by amie would be:
4n-10 (4n is the number of tickets Jay and Pillar sold together, 10 is the difference between them and Amie).
