82-10=72
72/6=12
answer is 12
Answer:
they aren't the same ratio
Step-by-step explanation:
ratio of 5:10 then 9:15
5/10 and 9/15
and that is simplified
2.5/5 and 3/5 so they aren't the same ratio
Answer: 306in^3
method: I would split the cross-section (the trapezium at the front) into two shapes. You first have your rectangle with dimensions of 4 and 7, and your triangle with dimensions of height 4 and base 3 (10 - 7 = 3). 4 × 7 = 28in^2, 4 × 3 = 12, 12 ÷ 2 = 6in^2. The total surface area of the cross-section is therefore 6 + 28 = 34in^2. Now, to find the volume, you just multiply that by 9 which is 306in^3, which is your answer. I hope this helps!
Let the two numbers be x and y, with y being larger than x.
Then y=3x+1.
Also, 8x-2y= 10.
The first equation has already been solved for y. Substitute 3x+1 for y in the second equation:
8x-2(3x+1)=10, or 8x - 6x - 2 = 10, or 2x = 12 and x = 6.
If x = 6, then by the first equation y must be 3(6)+1, or 19.
The numbers are 6 and 19.
