Step-by-step explanation:
That probability is 1/6 (one in six). Certainly this outcome could happen, but the probability that it won't happen is 1 - 1/6, or 5/6. Answer C is correct.
Answer:
42
Step-by-step explanation:
87.5% of 48
= (87.5/100) x 48
=0.875 x 48
= 42
Answer:
To decide whether to add or subtract, determine if the values of the coefficients are the same or opposites:
. If the values are the same, subtract the equations.
• If the values are opposites or additive inverses, add the equations.
Step-by-step explanation:
Given
Required
How to solve
Options (1) and (2) are incorrect because none of the options eliminate x or y.
For option (3),
- Check for the coefficients of x and y
- If they are the same (sign and value), then subtract; otherwise add
For instance:
Rewrite the second equation
The coefficient of y are the same, so we subtract;
<em>See that y has been eliminated</em>
Answer:
16 and the square root of 1369 is 37
Step-by-step explanation:
Given that <span>∆ABC rotates around point D to create ∆A′B′C′.
</span>
<span>Line BC is a horizontal line such that the length of BC is 2 units. Also line AB is a vertical line such that the length of AB is 3 units.
Based on the position of B'C', shown in the figure, the coordinates of A′ are will be vertical to the cordinate of B' going downwards with a length of 3 units. This means that the x-value of the coordinate of A' is the same as that of B' but the y-value of the coordinate of A' is 3 units less than that of B'.
The coordinate of B' is (4, 4).
Therefore, the coordinate of A' is (4, 4 - 3) = (4, 1).</span>
