Answer:
a = -⅓
b = 3
Step-by-step explanation:
-3a + b = 4
3a + b = 2
b = 4 + 3a = 2 - 3a
6a = -2
a = -2/6
a = - ⅓
-> b = 4 + 3(-⅓)
b = 4 - 1
b = 3
$70 = 270 min
x = 1260 min
Where x is the charge of phone service per 1260 min.
Cross multiply:
1260 * 70 = 270 * x
88200 = 270x
88200/270 = x
x = 326.67
The total charge of cellular phone service for 1260 min is $326.67
Your question has been heard loud and clear.
2^0= 1
5^1= 5
4^3=64
2^0+5^1+4^3/7= 1+5+64/7 = 6+64/7= 15.14
So , 2^0+5^1+4^3/7 = 15.14

Given:
Monthly fees for the local pool are $8 per month and $2 per visit.
Hector pays $34 in pool fees total for the month.
To find:
The number of times he visit the pool.
Solution:
We have,
Monthly fee of pool = $8
Additional fee = $2 per visit
Let Hector visit x times.
Additional fee for x times = $2x
Total fee = Monthly fee + Additional fee



Divide both sides by 2.


Therefore, Hector visit the pool 13 times.
Answer:
The table is attached!
Step-by-step explanation:
- 6 students play both musical instrument and a sport
- 3 students play neither a musical instrument nor a sport
- 14 students in total play a sport
Given: There are 24 students in the class
The number of students that does not play a sport is 24 - 14 = 10
The number of students that does not play a musical instrument but play a sport = 14 - 6 = 8
The frequency table thus is attached below:
