Which fraction is equivalent to 3/-5
-3(-5x+2)+x-3=39 solve for x
Answer:
the value of x = 3
Step-by-step explanation:
-3 (-5x+2)+x-3=39
open the bracket by multiply each by -3
15x-6+x-3=39
collect the like terms
16x-9=39
16x=39+9
16x=48

Question 3. The smallest digit by
which *' should be replaced in
710*95, so that the number formed is
divisible by 3 is:
Answer:
2
Step-by-step explanation:
Given:
710*95
Find the smallest digit by
which * should be replaced, so that the number formed is
divisible by 3
The first step is to add the numbers
7 + 1 + 0 + * + 9 + 5 = 22 + *
Next step is to find the multiples of 3
3 = 6, 9, 12, 15, 18, 21, 24, 27, 30
Step 3:
Since the addition of the digits = 22 + *
Then find a number to add to 22 which gives the next multiples of 3 after 22(that is 24)
24 = 22 + *
* = 24 - 22
= 2
* = 2
Substituting * = 2 into 710*95
We have,
710295
Therefore, the smallest digit by
which * should be replaced, so that the number formed is
divisible by 3 is 2
Check:
710,295 / 3
= 236,765

Why does the solution for an absolute value equation or inequality typically result in a pair of equations or inequalities?
Why the solution for an absolute value equation or inequality typically result in a pair of equations or inequalities?
Because the absolute value equations behave differently in the different ranges.
For a given absolute value equation (or inequality)
| x - a| = b
We get two equations or inequalities:
x - a = b
x - a = - b
And this is why the solution leads to two equations, this originates in the fact that the parent absolute value function:
f(x) = |x|
Behaves differently if x is positive or negative.
f(x) = x if x > 0f(x) = -x if x < 0If you want to learn more, you can read:

[tex]-7^2 + 5^4[/tex]
Step-by-step explanation:
Essentially, you are seeing how much of each of the same term there is. Add the amount together, and it will be the exponent.
[tex](-7) * (-7) = -7^(1 + 1) = -7^2\\5 * 5 * 5 * 5 = 5^(1 + 1 + 1 + 1) = 5^4[/tex]
Combine the two terms together into an expression. Note that you cannot combine them.
[tex]-7^2 + 5^4[/tex] is your answer.
