1. The answer is C. 7 with an exponent of 3 means that you multiply 7 by itself three times, or 7 x 7 x 7.
2. The answer is A. 19 with an exponent of 3 is the same as 19 x 19 x 19.
Speed of the train : distance traveled / time of the travel = 10.1/(0.5)=<span>20.2 mph. Hope this helped!</span>
3/4 is not P. Because 3 out of the 4 quadrants is not purple.
Answer:
20%
Step-by-step explanation: The percent of error formula is |(theoretical value-actual value)/actual value|=percent of error. Substitute the values in. |(2.8-3.5)/3.5|=|(-0.7)/3.5|=0.2. The percent equal to 0.2 is 20%.
Answer:
C. Multiply the first equation by -4
Step-by-step explanation:
Hi there!
In order to eliminate the y values, we would have to find a number in which the sum of the top y value and the bottom y value would equal 0. In this case, the bottom y value is equal to +4 (the +4y), so we would have to find the number that would add to make that 0, which is -4. Since the y value for the top equation is 1, all we have to do is multiply the equation by -4 so that our y value is equal to -4y and the y can be eliminated.
I hope this helps!!
