Yes it is correct.........
Find two numbers with a sum of 20 and a difference of 14
Make two equations
X+Y=20
X-Y=14
Now add x since y cancels out and add 20+14 To end up with
2x=34
Now divide 2 both sides to get x alone
2x/2=34/2
X=17
Now substitute x answer to first equation and solve for y
17+y=20
Subtract 17 both sides
Y= 3
Your two numbers are
3 and 17
Answer:
- 40
Step-by-step explanation:
The absolute value always returns a positive value , that is
- | - 40 | = - | 40 | = - 40
So there are two potential ways you could do this. First just multiple the g=7 into the equation and then add. Or another possibility is to first add the 14g and 3g to get the 17g and then multiply it by the g value and subtract 98. So if we combine the g's and then multiply it by 7, the 17g becomes
. So now subtract 98 from 119,
. So the overall answer to the expression is 21 when g equals 7.
Answer:
z= 1.70 Since the test statistic is less than the critical value, we can conclude that the average length of an online video is not more than 8 minutes
