X=number of boys
y=number of girls.
We can suggest the following system of equations:
x+y=33
x/y=3/8
We solve this system of equations by substitution method.
x/y=3/8 ⇒x=3y/8
(3y/8)+y=33
least common multiple=8
3y+8y=33*8
11y=33*8
y=(33*8)/11
y=3*8
y=24
x+y=33
x+24=33
x=33-24
x=9
number of boys /total number of students=9/33=3/11
There are 9 boys and 24 girls in the class.
Answer: C: 9. since 3/11 of the students are boys.
Answer:
Greater than
Step-by-step explanation:
A positive number, fraction, etc. is always bigger than a number or a fraction with a negative sign, so therefore 8/11 is greater than -1/3.
You want an answer that says the following...
She spent eleven (11) hours while working at the library which can be represented by p and she earned an amount of cash of at least one hundred forty (140) dollars.
The correct answer is choice D.
You could use m= the lesser number and n as the greater number. Since one is 5 times the other you will start with m+5m=198. Then you will combine like terms so it will become 6m=198. Then you will solve it as a regular equation. m=33 and n=165.
