Answer:
Step-by-step explanation:
absolute(5x + 6) = x
There are 2 solutions to this
Solution 1
5x + 6 = x Subtract 5x from both sides.
5x - 5x + 6 = x - 5x
6 = - 4x Divide by - 4
6/ - 4 = -4x / -4
x = - 1.5
Solution 2
5x + 6 = - x
6 = -x - 5x
6 = - 6x
x = 6/-6
x = - 1
Here is a graph which shows the solutions.
Answer:
Less than 100. Z=83
Step-by-step explanation:
The mean is the average found by adding the sum of the data points and dividing by the number of them. Here there are 3 cars whose speeds are 101, 116, and Z or unknown. The mean of them is 100. Solve for Z.
100 =(101+116+Z)/3
300=217+Z
83=Z
What are the answer options?
Answer:
You should expect 4 of the next 20 children to enroll to be toddlers.
Step-by-step explanation:
This question is solved by proportions.
So far:
We have that of 2 + 8 = 10 children, 2 are toddlers, so the proportion of toddlers is 2/10 = 0.2.
How many of the next 20 children to enroll should you expect to be toddlers?
0.2 out of 20, so: 0.2*20 = 4
You should expect 4 of the next 20 children to enroll to be toddlers.
Out of 4 circles, 2 of them are shaded in
2 out of 4 are shaded
How many are shaded?
2/4 or 1/2
So half of the drawn circles are shaded.
Hope this helps!
