Answer:
So first, there is an acronym for the strategy, KFC.
°π°
Keep the first fraction. Ex, 4/5 ÷ 1/5
Flip the second fraction. Ex, 4/5 ÷ 5/1
Change symbol. Ex, 4/5 ÷ 5/1 turns into 4/5<em>x</em>5/1
Hmm, one way is this
there's 500 times 0.10 or 50 grams of salt in the water
if we want to make 50 grams=4% of everything, how much water do we need to add
50=4% of all
50=0.04 of all
divide both sides by 0.04
1250=all
so
500+what=1250
minus 500 both sides
what=750
750 grams of water
Answer:
Step-by-step explanation:
Solving for x. Want to solve for f instead?
Step 1 move all terms to one side
fx - 4x² + 100 =0
Step 2 Use the Quadratic Formula
x = -f + √f² + 1600 ÷ -8, -f-√f²+1600 ÷ -8
Done.
Answer:
b) (1,-7)
Step-by-step explanation:
the x changes by 4 so subtract the midpoint x by 4 to get x=1
then the y stays the same y= -7
