Answer:
4
Step-by-step explanation:
Solving for x gets us...
-4+8x=5-(5x-2)-2
-4+8x=5-5x+2-2
-4+8x=5-5x
8x+5x=5+4
13x=9
x = 9/13
The answer as a fraction is x = 9/13
In decimal form, the approximate answer is x = 0.6923076923077
Answer:
Easy, |-0.825| is less than |-0.875|
Step-by-step explanation:
| means absolute value, which means that it's asking you how far away from it is 0. When you see these |, the number is ALWAYS positive, so if it is a negative, change it to a positive. .825 is less than .875
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!
