Answer:
Step-by-step explanation:
27 is the "center" of a range of measurements of the height of the guard rail. The height could be as much as 30 inches or as little as 24 inches. The absolute value operator encloses "x - 27," where 27 is the "center." The acceptable excess or acceptable deficiency is 3 inches.
So now we can eliminate possible answers B and C, in both cases because 27 is inappropriately greater than 3.
Narrowing down our choices, we have h + 27 and h - 27 inside the absolute value operator. 27 is a positive quantity (height of the guard rail), so the inequality showing +27 as the "center" is correct; that is
D: |h - 27| ≤ 3 (measurements in inches).
Answer:
one solution
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
Answer:
its C. (3,7)
Step-by-step explanation:
Move the 6 to the other side which makes it to subtract meaning 2h=8-6
Then the ans will be 2h=2
Next move the 2 frm H to the other side which makes it to divide since near teh H it was in multiplication:
H=2/2
H=1 (answer)
Answer:
The two equivalent expression are 
and 
.
The Total cost at state fair will be $66.
Step-by-step explanation:
Given:
Number of friends = 6
Cost for admission for each at the fair = $9.50
Cost of each person ride on Ferris wheel = $1.50
We need to find the two equivalent expressions and then find the total cost.
Solution:
Let the Total Cost be denote by 'T'.
So we can say that;
Total Cost will be equal to Number of friends multiplied by sum of Cost for admission for each at the fair and Cost of each person ride on Ferris wheel.
framing in equation form we get;
Now Applying Distributive property we get;
Hence The two equivalent expression are and .
On Solving the above equation we get;
Hence The Total cost to state fair will be $66.
