Answer:
The number of small and large boxes purchased are:
- 2 small boxes.
- 6 large boxes.
Step-by-step explanation:
To solve the unknowns, two equations must be established with the information provided:
- 150X + 400Y = 2700 (the price of the boxes and the final number of nails, where X is the small boxes and Y the large boxes)
- Y = 3X (Large boxes are triple the small ones)
Then equation 2 is replaced in equation one and variable X is cleared:
- 150X + 400 (3X) = 2700
- 150X + 1200X = 2700
- 1350X = 2700
- X = 2700/1350
- <u>X = 2
</u>
Finally, the value of X is replaced in equation 2 to find the number of large boxes:
- Y = 3X
- Y = 3 (2)
- <u>Y = 6</u>
Answer:
the answer would be 39 nickels and 17 quarters
Step-by-step explanation:
i did guess and check so i will just give the answer and the work for it
4.25/.25=17 quarters
56-17=39
39*.05=1.95
1.95+4.25=6.20
Answer:
5,-3
Step-by-step explanation:
Answer:
D.
Step-by-step explanation:
The subtraction property involves subtracting the same number that is subtracted from one side of the equal sign and also subtracting same from the other side of the equal sign
For example: y + 3 = 2
To apply the subtraction property, subtract 3 from each side. Thus:
y + 3 = 2 - 3
From the given equation solved, the subtraction property was not applied in any of the steps shown.
For this problem, we'll use two proportions:
THE FIRST PROPORTION:
x/86 = 52/100
100x = 4472
x = 44.72
THE SECOND PROPORTION:
x/52 = 35/100
100x = 1820
x = 18.2
FINAL ADDITION:
18.2 + 44.72 = 62.92
The answer is 62.92
Hope this helps!! :)
