Answer:
1:17
Step-by-step explanation:
Find out how long it it between 5.30pm and 9am. This is 8 hours 30 minutes or 510 minutes.
Now, arrange them in the ratio of Lunch Break to Total office time
30:510. This can be simplified to 1:17
Please check if the question is worded correctly, just in case. Because ratio questions are usually based on a part and the remaining parts of the same thing, and not part to whole.
Anyway. The answer given if for the question you have typed.
Hope this helps.
Answer:
Step-by-step explanation:
1st side X-17
2nd side X
3rd side X-6
(X-17)+(X)+(X-6) = 49
-17-6 = -23
X+X+X-23 = 49
3X-23 = 49
3X-23+23 = 49 + 23
3X = 72
3x/3 = 72/3
x = 24
Now plug it in
(24-17)+24+(24-6) = 49
7+24+18 = 49
Answer:
-1/7=n
Step-by-step explanation:
We can use cross products to solve
5 7
-------- = ------
n+3 4
5*4 = 7*(n+3)
20 = 7*(n+3)
Distribute
20 = 7n+21
subtract 21 from each side
20-21 = 7n+21-21
-1 = 7n
Divide each side by 7
-1/7 = 7n/7
-1/7=n
Answer:
-8
Step-by-step explanation:
-1 - y = x
0 - -4 = 4
x / 4 = -2
x = 4 * -2
x = -8
Answer:
(5,354 + x)
or
536.4*x
Step-by-step explanation:
We know that x = 10.
Now we want to write an expression (in terms of x) for the number 5,364.
This could be really trivial, remember that x = 10.
Then: (x - 10) = 0
And if we add zero to a number, the result is the same number, then if we add this to 5,364 the number does not change.
5,364 = 5,364 + (x - 10) = 5,364 + x - 10
5,364 = 5,354 + x
So (5,354 + x) is a expression for the number 5,364 in terms of x.
Of course, this is a really simple example, we could do a more complex case if we know that:
x/10 = 1
And the product between any real number and 1 is the same number.
Then:
(5,364)*(x/10) = 5,364
(5,364/10)*x = 5,364
536.4*x = 5,364
So we just found another expression for the number 5,364 in terms of x.
