Answer:
Messina has prepared 36 stickers and 8 students are in her class.
Step-by-step explanation:
Difference in remainder = 12 + 4
= 16
Difference per student = 5 - 3
= 2
No. of students = 16 ÷ 2
= 8
No. of stickers = 8 × 3 + 12 or 8 × 5 - 1
= 36
For this case we have the following expression:
1 / 2g ^ 2 + 7/2 + 3g ^ 2- 4 / 5g + 1/4
The first thing we must do is to group terms with the same degree:
g ^ 2 (1/2 + 3) - 4 / 5g + (7/2 + 1/4)
Then, rewriting we have:
(7/2) g ^ 2 - (4/5) g + (15/4)
Answer:
(7/2) g ^ 2 - (4/5) g + (15/4)
Answer:
y = 3.8 - 0.2x.
Step-by-step explanation:
y = k - 0.2x where k is the thickness of the ice before the melting starts and x = the number of weeks.
When x = 7, y = 2.4 therefore:
2.4 = k - 0.2*7
k = 2.4 + 1.4 = 3.8.
So our equation is y = 3.8 - 0.2x.
Given parameters:
First term of the sequence = x
Second term = x + 2
Third term = x + 4
Sum of the first three terms = 72
Unknown:
First term of the sequence = ?
Solution:
The sum of the first three terms is unknown;
(x) + (x + 2) + (x + 4) = 72
Solve for x;
x + x + 2 + x + 4 = 72
3x + 6 = 72
3x = 72 - 6
3x = 66
x = = 22
The first term of the sequence is 22
Answer:
9.5
Step-by-step explanation:
If c to a is 19 then you divide the distance by 2 and you get 9.5 for the two distances.
