First step: you have to plug in 6y+3 into the equation and solve
Example: 6y+3+2y = 5
Sold 2/5 in the morning.....leaving 3/5
he sold 3/4 of 3/5 in the afternoon......3/4 * 3/5 = 9/20
2/5 = 8/20
9/20 - 8/20 = 1/20...so he sold 1/20 more in the afternoon.
so if 1/20 = 24, then 20/20 = 24*20 = 480
so he started with 480 cartons
Answer:
it will turn out to be a repeating decimal so put a little line over the first 3 to the right of the decimal (517.8333333333)
Step-by-step explanation:
Answer:
Two solutions
Step-by-step explanation:
x^2-x=1
plug into the discrimiant fomurla
The asnwer ends up being 5
which is positive, meaning that the discriminant has two solutions
Postitive number = Two solutions
The answer is 0 = One solution
Negative number = No solutions
:)
1/5(10x−15)=1/4(12x−8)
1/5(10x−15)=1/4(12x−8)
Simplify:
(1/5)(10x)+(15)(−15)=(1/4)(12x)+(1/4)(−8)(Distribute)
2x+−3=3x+−2
2x−3=3x−2
Subtract 3x from both sides.
2x−3−3x=3x−2−3x
−x−3=−2
Add 3 to both sides.
−x−3+3=−2+3
−x=1
Divide both sides by -1.
−x/−1 = 1/−1
x=−1
