Answer:
7x+39>=53 and 16x+ 15>31 x>=2 (no solutions exist)
Step-by-step explanation:
Step-by-step explanation:
The above sequence is a geometric sequence
For an nth term in a geometric sequence

where
n is the number of terms
a is the first term
r is the common ratio
From the question
a = 5
r = 10/5 = 2
Therefore the explicit formula for this sequence is

Hope this helps you
Example 20 x 30 is similar to 3x2 which is 6. Just add the zeroes on the end:
600
25 to 2 means for every 25 students there are 2 teachers.
Divide the total number of teachers by their ratio:
190 / 2 = 95
Now multiply that by the student ratio:
95 * 25 = 2,375 total students.
Do your best remember volume is H+L+W and area is L*W
