The sum of two numbers is 13 and there difference is 5 what are the 2 numbers?

Answers

Answer 1
Answer: x + y = 13
x - y = 5

x = (13 - y)

(13-y) - y = 5

13 - 2y = 5
-2y = -8
y = 4

x - 4 = 5
x = 9

x=9, y = 4
Answer 2
Answer: x+y=13
x-y=5
we can addd these 2 equations to eliminate y

2x+0y=18
2x=18
divide both sides by 2
x=9

sub back
x+y=13
9+y=13
minus 9 both sides
y=4

the 2 numbers are 9 and 4

During unusually cold weather, the temperature in Miami beach was 10'C. This was 12 degrees more than in Tallahassee. What is the temperature Tallahassee

Answers

Answer:

-2°

Step-by-step explanation:

We have that the temperature in Miami beach was 10° C.

Also, this temperature is 12° more than the temperature in Tallahassee.

So, we get that,

Temperature in Miami = 12°  + Temperature in Tallahassee

i.e. Temperature in Tallahassee = Temperature in Miami - 12°

i.e. Temperature in Tallahassee = 10° - 12°

i.e. Temperature in Tallahassee = -2°

Hence, the temperature in Tallahassee is -2°.

The answer is -2'C !! ^_^
