7+25 / 18
32/18
or
1 14/18
or
1 7/9
Answer: 32/18 or 1 14/18 or 1 7/9
Step-by-step explanation:
-5x < 25
Divide both sides by the coefficient of -5
-5x/-5 < 25/-5
x > -5
when you divide both sides by a negative number in inequality, the sign changes to the opposite. for example < changes to >
Answer:
0.561
Step-by-step explanation:
To solve this problem we must resort to external information that I will leave attached with the answer, it is a table that for each value of n, gives us the critical values.
Returns the critical values for both the significant levels of 0.01 and 0.05.
If we go to the table we know that when n = 20 and the significant level is 0.01, the corresponding critical value is: 0.561
Step-by-step explanation:
y = x - 2
x + y = 12
Substitute the first expression for y into the second equation.
x + (x - 2) = 12
2x - 2 = 12
2x = 14
x = 7
Now plug into either equation to find y.
y = 7 - 2
y = 5
So the solution is (7, 5).
