Answer:
1/5x+51=2x+42
Step-by-step explanation:
1/5 of x, the number, plus 51 is equal to 2 times the number plus 42.
well, if we take 40 to be the 100%, what is 14 off of it in percentage?
12
Step-by-step explanation:
Quotient rule,
Do this,
a^(n-3)=a^9
Since the exponents have to be the same, this turned into a simple one step equation:
n-3=9
+3 +3
**n = 12, so the final answer is 12.
7z - 1/2 = 3z - 2
Subtract 3z to both sides:
4z - 1/2 = -2
Add 1/2 to both sides:
4z = -1 1/2
Divide 4 to both sides:
z = -0.375 or -3/8
Answer:
Zero
Step-by-step explanation:
Average rate of change can also be called as gradient or change in the respective variable , in this case we need the average rate of change of y which has the function y = -7
Since this is a linear function and if we draw the graph of y = -7 the graph would be parallel to the x-axis, and any line parallel to the x-axis has slope of zero , hence the average rate of change of the function y = -7 is zero
