Answer:
For 7x-9<12, the answer is x<3
For 14x+8>11, the answer is x>3/14
Step-by-step explanation: Isolate the variables by dividing each side by factors that do not contain the variable.
I hope this helps you out! :)
There are 100 centimeters in 1 meter. So to start with you must multiply 10000 by 100 to determine the number of centimeters in each race. This answer will be 1000000. Then to determine the number of centimeters in fifty races, you must multiply 1000000 by 50. This answer is 50000000. Then you must put it in scientific notation.
To do this you must move the decimal place over to the left until there is only one, nonzero number in front of it. Because you will move it to the left, your exponent will be positive. Therefore, your answer will be B.
Answer:
y= -5x + 2
Step-by-step explanation:
the slope is heading downwards, and down five units for each one across (hence m=5) and the y-intercept is 2 (hence the 2)
Answer:

Step-by-step explanation:
The formula for the area of a circle is : 
To work this out you would first have to work out the area of the circle. You can do this by multiplying pi by 8 squared, this gives you 201.06. This is because in order to calculate the volume you must calculate the area of one face of the shape.
The next step is to multiply 201.06 by 10, this gives you 2010.62.
1) Multiply pi by 8 squared.

2) Multiply 201.06 by 10.
