Sam needs 7 1/2 cups of orange juice to make punch for a group of her friends. She only has 5 1/3 cups. Write and solve an equat
Solnce55 [7]

Answer:

Equation is x+\frac{16}{3}=\frac{15}{2} where x denotes number of cups of orange juice needed by Sam.

x=\frac{13}{6}

Step-by-step explanation:

Let x denotes number of cups of orange juice needed by Sam.

Number of cups needed to make punch =7\frac{1}{2} =\frac{15}{2}

Number of cups with Sam =5\frac{1}{3}=\frac{16}{3}

Therefore,

x+\frac{16}{3}=\frac{15}{2}\\\\x=  \frac{15}{2}-\frac{16}{3}\\\\x=\frac{45-32}{6}\\\\x=\frac{13}{6}

klemol [59]

Answer:

Step-by-step explanation:

Hello, "the constant term has been written on the right side", it means that we add 18 to both sides to get.

x^2+3x-18=0\\\\x^2+3x=18\\\\\text{We can see the beginning of } (x+\dfrac{3}{2})^2 \\\\x^2+3x=(x+\dfrac{3}{2})^2-\dfrac{3^3}{2^2}=18\\\\(x+\dfrac{3}{2})^2=18+\dfrac{9}{4}=\dfrac{18*4+9}{4}=\dfrac{81}{4}

Hope this helps.

Thank you.
