Let Sister's age now = s
So Larry is now s + 8
In THREE Years Sister = s + 3
Larry = {s + 8} + 3
But We are told that he will be TWICE as old as Sister is NOW!!!
So s + 11 = {2s}
Solve s = 11
So Sister is ELEVEN Years old and Larry is NINETEEN Years old.
Answer:
x=
15
7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8x−
6
2
=x+12
8x+−3=x+12
8x−3=x+12
Step 2: Subtract x from both sides.
8x−3−x=x+12−x
7x−3=12
Step 3: Add 3 to both sides.
7x−3+3=12+3
7x=15
Step 4: Divide both sides by 7.
7x

Answer:
x + 8 <= 6, so x <= -2.
Step-by-step explanation
Greatest possible value of 7x is 7(-2) = -14.
Answer:
c . Two angles whose sum is 180°
Step-by-step explanation:
Hope it helps you in your learning process
First, combine like terms.
3y+3x>-6x+12
Next, because there can not be the same variable on both sides, add 6x to both sides.
3y+9x>12
