Answer: the system of linear equations to represent this scenario are
b + g = 30
2b = g + 12
Step-by-step explanation:
Let b represent the number of boys in the class.
Let g represent the number of girls in the class.
There are 30 students in the math class. This can be expressed as
b + g = 30
There are 6 more boys than 1/2 the number of girls in the class. This can be expressed as
b = g/2 + 6
Cross multiplying by 2, the expression becomes
2b = g + 12
X=61 is your answer, hope this helps
Answer:
Step-by-step explanation:
6n−20=−2n+4(1−3n)
Simplify both sides of the equation.
−6n−20=−2n+4(1−3n)
−6n+−20=−2n+(4)(1)+(4)(−3n)(Distribute)
−6n+−20=−2n+4+−12n
−6n−20=(−2n+−12n)+(4)(Combine Like Terms)
−6n−20=−14n+4
−6n−20=−14n+4
Add 14n to both sides.
−6n−20+14n=−14n+4+14n
8n−20=4
Add 20 to both sides.
8n−20+20=4+20
8n=24
Divide both sides by 8.
8n/8 = 24/8
n=3
