X+y=1 is really -1+0=1 so x = -1 y = 0

2x-y=-2 is really 2*0+2=-2 so x = 0 y = 2

Jenna is driving 400 miles to visit her grandmother. She managesto travel the first 100 miles of her trip in two hours. Is she c

dalvyx [7]

Answer:

Jenna will complete remaining distance in 6 hours.

Step-by-step explanation:

Since we know that $\text{Speed}=\frac{\text{Distance}}{\text{Time}}$ . Let us find the rate at which Jenna traveled 100 miles.

$\text{Speed}=\frac{100\text{ miles}}{2\text{ hours}}$

$\text{Speed}=50\frac{\text{ miles}}{\text{ hours}}$

Remaining distance is 400-100=300.

Now let us find the time Jenna will take to travel 300 miles.

$\text{Time}=\frac{300}{50}$

$\text{Time}=6$

Therefore, Jenna took 6 hours to complete remaining distance.

mihalych1998 [28]

Answer:

Step-by-step explanation:

The probability of picking a maths student = 21% = 21/100

The probability of picking a science student = 15% = 15/100 = 3/20

The probability of picking in both = 6/100 = 3/50

The probability that the student is in maths or science = 21/100 - 15/100 = 6/100 = 6%.
