Question

Please help!

Today, the temperature in Boston
is -1 degrees and it is expected to rise
3 degrees each day.
It's 6 degrees in San Francisco and is
expected to fall 1 degree every two
days.
After how many days will the
two temperatures be the same?

Equation 1:
Equation 2:
Answer:

Answer 1

The temperature will be the same in two days

Explanation:

We can set up two equations to represent the temperatures in Boston (B) and San Francisco (SF) after a certain number of days (d):

B = -1 + 3d

SF = 6 - (d/2)

To find the number of days when the two temperatures will be the same, we can set the equations equal to each other and solve for d:

-1 + 3d = 6 - (d/2)

Multiplying both sides by 2 to eliminate the fraction:

-2 + 6d = 12 - d

Combining like terms:

7d = 14

Dividing both sides by 7:

d = 2

Therefore, the two temperatures will be the same after 2 days.
