Answer:

(-3, 1).

Step-by-step explanation:

2x + 7y = 1 -------------(A)

x + 5y = 2 Multiply this by -2:

-2x - 10y = -4 Add this equation to equation (A):

0 - 3y = -3

3y = 3

y = 1.

Substitute this in equation (A):

2x + 7(1) = 1

2x = -6

x = -3.

Check if these 2 values are correct in the second equation:

-3 + 5(1) = 2

2 = 2.

Answer:

148 minutes

Step-by-step explanation:

It is 3{:}32\text{ p.M.}3:32 p.M.3, colon, 32, start text, space, p, point, m, point, end text and Emma has gymnastics lessons at 6{:}00\text{ p.M.}6:00 p.M.6, colon, 00, start text, space, p, point, m, point, end text How many minutes are there until Emma's gymnastics lessons?\

The time is 3:32 pm

Emma's gymnastics lesson is at 6:00 pm

6:00 pm - 3:32 pm = 2 hours 28 minutes

That is, we have 28 minutes before 4:00 pm

And 2 hours from 4:00 pm to 6:00 pm making a total of 2 hours 28 minutes

How many minutes are there until Emma's gymnastics lessons?

Convert 2 hours 28 minutes to minutes

1 hour = 60 minutes

2 hours = 60 minutes × 2 = 120 minutes

120 minutes + 28 minutes = 148 minutes

2 hours 28 minutes to minutes = 148 minutes
