I made 10 and three fifths gallons of soup of which 6 and one quarter gallons was chicken noodle. How much was not chicken noodl
nata0808 [166]

Answer: 4 7/20 gallons

Step-by-step explanation:

Gallons of soup made = 10 3/5

Gallons that was chicken noodle = 6 1/4

The gallons that wasn't chicken noodle will be:

= 10 3/5 - 6 1/4

= 10 12/20 - 6 5/20

= 4 7/20

Therefore, 4 7/20 gallons wasn't chicken noodle.

What non-zero rational number must be placed in the square so that the simplified product of these two binomials is a binomial:
aleksandrvk [35]

The product would expand to

(7t-10)(5t+x)=35t^2+7tx-50t-10x=35t^2+(7x-50)t-10x

This is a trinomial, and the only way to make it a binomial is to cancel out a coefficient using our variable x.

So, we can cancel either the linear term or the constant term.

In the first case, we require

7x-50=0 \iff 7x=50 \iff x=\dfrac{50}{7}=\dfrac{49}{7}+\dfrac{1}{7}=7\dfrac{1}{7}

In the second case, we require

-10x=0\iff 10x=0 \iff x=0

But x must be a non-zero rational number, so this solution is not feasible.

Could someone please help me with these systems. I have to use substitution.
FromTheMoon [43]
Isolate one term (x or y) in one of the equations

6x+6y=0
6x=-6y
X= -1y

Substitute x=-y into the other equation

-7(-y) + 2y =18

7y + 2y =18

9y=18

Y=2

Substitute y=2 into 6x+6y=0

6x + 6(2) = 0

6x + 12=0

6x= -12

X = -2
