First step, expand the left side (multiply together) (apply FOIL/distribution property)
2nd step, solve so that one side is zero, by adding/subtracting like terms
3rd step, solve for x
Answer:
- v = 8
- x = -12
Step-by-step explanation:
1. I like to work with positive numbers, so the first thing I'd do is multiply the equation by -1.
2v + 7 = 23
2v = 16 . . . . . subtract 7
v = 8 . . . . . . . divide by 2
<em>Check</em>
-2(8) -7 = -23 . . . . true
___
2. (x/4) -5 = -8
x/4 = -3 . . . . . . . add 5
x = -12 . . . . . . . . multiply by 4
<em>Check</em>
(-12/4) -5 = -8 . . . . true
The number would be -10.8
19 + (-10.8) = 8.2
I hope that helps!
You're question asks why the given mixed numbers are equal.
In fact, they're equal.
Lets make it easier for you to understand:
8 4/3 has a improper fraction "4/3", that fraction is over 1 whole.
You could look at 8 4/3 as:
8 + 3/3 + 1/3
The 3/3 turns into 1:
8 + 1 + 1/3
9 + 1/3
9 1/3
You would see that it turns into 9 1/3, therefore they are equal.
Answer:
15625
Step-by-step explanation:
Lets use the information to present the question into mathematical form:
so this means -5 is multiplying itself 6 times so this means
value of negative 5 superscript 6 means
= -5 x -5 x -5 x -5 x -5 x -5
so the answer is 15625
