4/5-2/3= 12/15-10/15 (common denominator is 15)=2/15 pounds of seeds left
Answer:
The correct way to complete the sentences is as follows:
As Jimmy sells more hot dogs, his profit will increase.
Jimmy sells the hot dogs for $1 each.
Jimmy needs to sell 8 hot dogs to recover the money he invested.
If Jimmy sells 15 hot dogs, he will make $7 in profit.
To make $12 in profit, Jimmy would have to sell 20 hot dogs.
Answer: The first equation should be multiplied by 9 and the second equation by −4, to eliminate the y-terms and solve for x in the fewest steps.
Step-by-step explanation:
Given : Equation (1) 5x − 4y = 28
Equation (2) 3x - 9y = 30
to eliminate the y-terms and solve for x in the fewest steps, we should multiply equation (1) by 9 and equation (2) by -4 such that
9(5x − 4y) =9 (28)⇒45x-36y=252
-4(3x - 9y) = -4(30)⇒ -12x+36y= -120
Now adding both equations, y-term eliminated and we get, 45x-12x=132
⇒33x=132⇒x=4.
Answer:
For this case, the first thing we must do is define variables:
x: number of hammers
y: number of wrenches
We write the system of inequations:
10x + 6y <= 120
x + y> = 14
