Answer:
V (volume) = 30
Step-by-step explanation:
V=whl=2·3·5=30
Multiple
7•7+14=3•3
Calculate
49+14=9
Equality
63=9
The correct answer is x= -1 or -3
Please note that in the original problem you have horizontal division symbols:
4 1 3
--- x - ---- = -----
5 10 10
On the other hand, you have typed <span>4/5x-1/10=3/10. To avoid ambiguity you must enclose the fractions inside parentheses:
</span><span>(4/5)x- (1/10) = (3/10). Otherwise, your reader will not know for sure whether you meant 4 / (5x) or (4/5)x.
</span><span>After you've typed in these parentheses, your next task is to mult. all the terms of this equation by 10, to remove the fractions. Result:
8x - 1 = 3, or 8x = 4, or x = 1/2 (answer)</span>
