Let's make a ratio!
okay this isn't the elmo show but still, let's start with reducing fractions
14/21 = 2/3 with a factor of 7
Only 2/3 of your "party peeps" can attend, so...
You only need 2/3 of your recipe!
2/3 of 6 = 4 cups of sugar
2/3 of 3 = 2 eggs
2/3 of 9 = 6 cups of flower
2/3 of 2 = (4/3) cups of oil
substitute the values from the quadratic formula.
a= 3
b= -5
c= -3
simplify the numerator
5±√61/2 times 3
Multiply 2 by 3

ANSWER:5±√61/6</em></h2>
Answer:
x=2/9,y=26/9
Step-by-step explanation:
This is a simultaneous equation
16x+5y=-2..(1)
4x-y=-2...(2)
From (2) make y the subject of formula
y=4x+2..(3)
Substitute (3) into (1)
16x+5(4x+2)=-2
16x+20x+10=-2
36x-10=-2
Add 10 to both sides
36x=8
Divide both sides by 36
x=8/36
Divide both denominator and numerator by 4
x=2/9
Substitute the value x into (3)
y=4(2/9)+2
y=8/9+2
Let the LCM be 9
y=8+18/9
y=26/9
Therefore x=2/9,y=26/9
81 is the correct answer
hope it helps you have a good day
Answer:
Step-by-step explanation:
You need the Law of Cosines for this, namely:
where x is the missing side.
and
so
x = 18.0 or just 18
