Answer:
17
Step-by-step explanation:
If a sports care traveled 312 miles in 6 hours it was going 52 mph, going at 52mph for 8 hours will result in 416 miles traveled
(-2) +(-20) =-22
2+20=22 make result negative
Answer:
Step-by-step explanation:
Kira has 3/8 of the total of Jelly Beans available. Morgan has the other 5/8
So if there are 56 Jelly beans in total 3/8 * 56 = 21 which would be Kira's share.
Morgan would have 5/8 * 58 = 35 Jelly beans (Not that this is really relevant).
Now Kira and Mann have a ratio of 6:1 which means that she has 6/7 of the total between those two. He therefore must have 1/7 of the total.
Her total is 21.
1/7 of 21 = 3
Therefore Mann would have 3 jelly beans.
3/8 * 1/7 is the total the number of Jelly Beans that he would have if the total was N
N(3/8 * 1/7) = N (3/56)
System A:
6x + y = 2
-x - y = -3
System B:
2x - 3y = -10
-x-y = -3
Solve:
System A:
6x + y = 2
y = 2 - 6x
-x - (2-6x) = -3
-x - 2 + 6x = -3
5x = -3 + 2
5x = -1
x = -1/5
y = 2 - 6(-1/5)
y = 2 + 6/5
y = 2 + 1.2
y = 3.2 System A: x = -1/5 or -0.2 ; y = 3 1/5 or 3.2
System B:
2x - 3y = -10
2x = -10 + 3y
x = -5 + 1.5y
-x - y = -3
-(-5 + 1.5y) -y = -3
5 - 1.5y - y = -3
-2.5y = -3 - 5
-2.5y = -8
y = 3.2
x = -5 + 1.5(3.2)
x = -5 + 4.8
x = -0.2 System B: x = -0.2 ; y = 3.2
<span>B) They will have the same solution because the first equations of both the systems have the same graph.</span>
