Answer:
$1.25
Step-by-step explanation:
The graph shows that 3 pens cost $3.75 which means each pen costs more than $1 so we know that the greater number will be the numerator in our division equation. Divide 3.75 by 3 to get the unit rate.
3.75/3=1.25
Each pen costs 1.25
You can check your work by plugging it into the other points.
6*1.25=7.5 -So that second point is correct
9*1.25=11.25- The third point is also correct meaning we got the right answer
To solve the first problem, you have to multiply both sides by 3, or 3/1.
3/1(n/3)=2(3)
3n/3=6
1n=6, or n=6.
To solve problem 2, simply divide both sides by 5.
5t/5=20/5
t=4
Hope this helps :-)
The answer would be option C) p= 6.25h. If you plug in h (hours worked) and multiply it by 6.25 it will equal p (pay).
Ex. p= 6.25(2) would result in the answer p= $12.50.
Answer:
A
Step-by-step explanation:
The sequence of positive odd numbers is
1, 3, 5, 7, ......
This is an arithmetic sequence with common difference d
d = 3 - 1 = 5 - 3 = 7 - 5 = 2
The sum to n terms of an arithmetic sequence is
= 
[2a + (n - 1)d ]
where a is the first term
here a = 1, d = 2, n = 12, hence
= 
[1 + (11 × 2) ]
= 6 [ 2 + (11 × 2) ]
= 6 × 24 = 144 → A
