Semester 1:
let the number of students in the art class be 2a, and the number of the students in the gym class be 7a. (check: the ratio is 2a:7a = 2:7)
so the total number of students is 9a.
semester 2:
the 9a students are go to the art class and gym class at a a ratio of 5: 4,
so 5a students go to the art class, and 4a students go to the gym class.
<span>75 students are in art class in second semester means that 5a=75,
so a=75/5=15.
In the 1st semester the number of students was:
art class: 2a=2*15=30
gym class: 7a=7*15=105</span>
Answer:
Equation: x + 11 = 122
Answer: x = 111
Step-by-step explanation:
- Write it out: x + 11 = 122
- Subtract 11 from each side, so it now looks like this: x = 111
I hope this helps!
<span>(7x-8) (6x+11)=0
7x-8 = 0 then x = 8/7
6x+11 = 0 then x = -11/6
answer
</span>x = -11/6 and x = 8/7
$550.
30.75 x 12 = 369
550 - 369 = $181
After 1 year, michael will be left with $181
