Point A=-1.3
Point B= 1.3
These 2 points are reciprocals, which means that their sum is Zero. So basically they are exact opposites.
I have no idea but i really need help on this too33458584837
Solve for q:
2 p - 1/q = r/q + 4
Bring 2 p - 1/q together using the common denominator q. Bring r/q + 4 together using the common denominator q:
(2 p q - 1)/q = (4 q + r)/q
Multiply both sides by q:
2 p q - 1 = 4 q + r
Subtract 4 q - 1 from both sides:
q (2 p - 4) = r + 1
Divide both sides by 2 p - 4:
Answer: q = (r + 1)/(2 p - 4)
If the number was x, then you could write the expression x-5 since you show five less or subtracted from the number. Hope this helps.
<span>Quantity Equation: t + s = 20 gallons
Lemon content Eq: 20t+70s = 40*20 gallons
</span><span>Modify for elimination:
2t + 2s = 2*20
2t + 7s = 4*20
</span><span>Subtract and solve for "s":
5s = 2*20
s = 8 gallons (amt. of 70% mix needed)
t = 20-8 = 12 gallons (amt of 20% mix needed)</span>
