How many solutions does this system have?

Mathematics
1 answer:
poizon [28]4 years ago
7 0

Answer:

Step-by-step explanation:

5x - y = 3.......(1)

2y = 10x+2.....(2)

Rearranging (2)

-10x + 2y = 2......(3)

Multiply equation (1) by 2

10x - 2y = 6..........(4)

Adding (3) and (4)

-10x + 10x + 2y - 2y = 2 + 6

No solution since both x and y are eliminated.

Emma is building a wall around her garden. It has take 45 minutes,and she is 75% done what is the told time it will take Emma to
kicyunya [14]
Ok so first we need to write a fraction. 

75 percent/45 mins

then we convert that into a unit rate

1.67 percent/1 min

so, now that we have the unit rate, we know exactly how fast she is moving.

Now, we divide 25 by 1.67 because 25%  is the distance between the completion of the gate and current state of the gate. 

So we get 14.97, which we can safely round up to 15.

It will take her 15 mins more to finish the gate, and it has already taken 45, so 45+15=60

60 MINS TOTAL/ 1 HOUR
