First you need to distribute the negative to 5,3x and -4 now you have this:
-3.5x+7-5.3x +4 rearrange and combine like terms (matching x's with x's etc.)
-3,5x -5.3x +7+4
-8.8x +11 your final answer there are no more like terms that you can combine.
Let the fruit mixture of $5.7 per pound be for x pounds.
The nut of $14.55 per pound would then be: (10 -x).
Since the total blend of both = 10 pounds, selling for $9.24 per pound.
cost of 1st type + cost of second type = Total cost of blend mixture
5.7*x + 14.55*(10 - x) = 9.24*10
5.7x + 145.5 - 14.55x = 92.4
5.7x - 14.55x = 92.4 - 145.5
-8.85x = -53.1
x = -53.1/-8.85
x = 6
The other will be (10 -x) = 10 - 6 = 4.
She should use 6 lb of fruit mixture and 4 lb of nuts.
To prevent any outside forces from intervening.
Answer:
the scale factor is 25, 3000/125 scaled down,
Step-by-step explanation:
you can also explain this with a 25:1 ratio, 25 inches from the original scaled to 1 inch for the photo copy.
