{x:x>6}
Step-by-step explanation:
Find out the expressions for the number of sweets sue and tony have now .
To proof
As given
Sue has 18 sweets. tony has 18 sweets.sue gives tony x sweets
thus
sue sweets = 18 - x
Tony sweets = 18 + x
As given
Sue then eats 5 sweets. Tony then eats half of his sweets
sue sweets becomes = 18 -5 -x
= 13 - x
Tony sweets become= 18 + x /2
= 9+ x/2
hence proved.
Hence proved
3.695 was rounded to the nearest thousandths and 4 is rounded to the nearest ones place. Hope that helped :)
1) Equal the two together (not including the ‘y’)
-x -2 = 4x + 3
2) put x together and the whole number together
* when switching sides, signs ( + & -) changes, watch out for that *
-x - 4x = 3 + 2
-5x = 5 divide by the # with x so you have x
—— ——-
-5. -5
x = -1
therefore, x = -1
For y just plug x into either equation
I’ll use y = 4x + 3
y = 4(-1) + 3
y = -4 + 3
y = -1
therefore, y = -1
