Answer:
x=8
Step-by-step explanation:
4.6x-9.3=27.5
+9.3 +9.3
-------------------------
4.6x=35.8
4.6x/4.6 35.8/4.6
x=8
Answer:
154 students
Step-by-step explanation:
First get the total number of students .
This can be gotten by
12% of A = 21
Where A represents the total number of students.
12% represents the % of A that chose to study French and 21 is the number of students that studied French .
Therefore,
12% /100% x A = 21
0.12 x A = 21
Divide both sides by 0.12
0.12/0.12 x A = 21/0.12
A = 175
The total number of students is 175.
If 21 chose to study French their freshman year ,number of students that chose not to will be total number of students minus number of those who chose to study French.
That’s
175 - 21
= 154
154 students chose not to study French their freshman year
Answer:
Josie: 100 + 5x
Allanah: 10 + 20x
x is to represent the unknown variable of how many times they will repeat this process.
Explanation:
1. Identify the different constellations of variables. Here there are three:
2. Combine coefficients of each of the different variable constellations:
(8.1 -2.8)b +(6.7 +0.9)a +(2.5 +7)
5.3b +7.8a +9.5
3. Perform any other operations that might be required depending on the sort of equivalent wanted. For example, one could write ...
5.3(b +(78/53)a) +9.5 . . . . . . . shows the weight of a relative to b
