x+y=18897
x=y+673
2y+673 = 18897
2y = 18224
y= 9112
x = 9112+673 = 9785
9112 + 9785 = 18897
so one country is 9112 and the second country is 9785
Answer:
Lemme explain it down below
Step-by-step explanation:
150/3 would be 50 per hour.
15/3 would be 5 per hour.
120/2 would be 60 per hour
<span>Given
situations:
Let my number be X
=> Triple my number = 3x
=> add six = + 6
=> subtract twice my number = -2x
=> my number plus 3 = x + 3
now, that we simplify each given word phrase, we will now create our equation.
=> 3x + 6 – 2x = x + 3
=> 3x – 2x = x + 3 – 6
=> x = x – 3
=> x – x = -3
Where x will be cancelled out, thus, this statement is not valid.</span><span>

31.5 times 1.8.
=31.5×.8+31.5×1
=25.2+31.5
=56.7
There are 180 degree's in a triangle. to find one side add the two sides you do know and subtract it from 180 degree's.
