Answer:
1
Step-by-step explanation:
Assuming, we want to find the value of 
Recall that: any non-zero number exponent zero is 1.
Using this property, we simplify our expression to
since 
Now using the property of exponents: 
This implies that:
The correct answer is 1
Answer:
435=107+82+246
Step-by-step explanation:
I think this is correct. Someone correct me if I am wrong, but I took 435 and subtracted 107, then I took that number and divided it by 4 and took one of those 4 and put it in the equation then multiplied the last three.

See explanation
Step-by-step explanation:
The constant of variation is found using the slope formula:

The given relation is
X : -2 , -3, -4, -5
Y : -5, -7.5,-10,-12.5
We can use any two ordered pair to find the constant of variation.
Using (-2,-5) and (-3,-7.5), we have

The constant of variation is 2.5
We need to repeat this for all the options to identify the one with -2.5 as slope.
unfortunately, you did not provide the remaining options.
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown".
Step-by-step explanation:
In x + 2 = 7, x is a variable, but we can work out its value if we try:)
Multiply everything by -3 so it will be n-15>4 then add 15 to both sides so it will be n>19 and thats the answer.
