Answer:
21 + x = 35
Step-by-step explanation:
if you do inverse operations you will find that x = 35-21
which is 14
<h3>Answer: 10</h3>
=======================================================
Explanation:
We'll start off converting each mixed number into an improper fraction.
The formula to use is 
So,
And,
So the task of computing 
is exactly the same as computing 
Notice how we have an 8 up top and an 8 down below. Those 8's cancel out and we're left with 
. That fraction does not reduce any further.
The last step is to convert that improper fraction result to a mixed number.
Or you could note that 17/3 leads to 5 remainder 2. The 5 is the whole part and the 2 forms the numerator of the fractional part 2/3.
The value is in 
form where
Therefore, A+b+c = 5+2+3 = 10
Average rate of change refers to the slope of a function/equation.
To solve this, plug in for both x values and calculate the average, or mean.
x = 1
f(1) = 5(2)^1
= 5(2)
= 10
x = 5
f(5) = 5(2)^5
= 5(32)
= 160
Now, you calculate the average:
10 + 160 = 170
Divide by 2 and you get 85.
Answer:
No
Step-by-step explanation:
We can plug in the ordered pair (6,-1) into the equation. Remember that 6 is the x coordinate therefore we plug it in for x and that -1 is the y coordinate so we should plug it in for y.
6x+3y=6(6)+3(-1)=36-3=33
Since 33 is not equivalent to 15, (6, -1) is not a solution to the equation.
