Answer: D. 6 and 4
Explanation:
2643 - 180 = 2463 the 6 changes to a 4, and the 4 changes to a 6.
Answer:
<h2>d = 31</h2>
Step-by-step explanation:
a = bc - d
Substitute a = -16, b = 3 and c = 5:
-16 = (3)(5) - d
-16 = 15 - d <em>subtract 15 from both sides</em>
-16 - 15 = 15 - 15 - d
-31 = -d <em>change the signs</em>
31 = d
Answer:
x is y less than z
Step-by-step explanation:
The given equation is x + y = z
This equation relates the whole numbers x, y, and z.
This equation can be rearranged to make x the subject of the formula or to make y the subject of the formula. When this is done, the relationship between the terms or numbers would be clearly expressed.
Making y the subject of the formula, it becomes
y = z-x (this shows that z is greater than y by x)
Making x the subject of the formula, it becomes
x = z-y (this shows that z is greater than x by y)
Looking at the options given, the correct comparisons between z and x is
x is y less than z
<u>Answer:</u>
(x, y) = (-2, 2)
<u>Step-by-step explanation:</u>
We are given the following two equations which we are to solve using the substitution method:
--- (1)
--- (2)
From equation (1):
Substituting this value of x in (2) to get:
![x = [tex]x - 2y = -6\\\\(y-4)-2y=-6\\\\-y=-6+4\\\\-y=-2](https://tex.z-dn.net/?f=x%20%3D%20%5Btex%5Dx%20-%202y%20%3D%20-6%5C%5C%5C%5C%28y-4%29-2y%3D-6%5C%5C%5C%5C-y%3D-6%2B4%5C%5C%5C%5C-y%3D-2)
[/tex]
y = 2
Substituting the value of y in (1) to get x:
x = -2
Therefore, (x, y) = (-2, 2).
