Answer:
k-5. The question seems incomplete though.
5m + 4m = 72
Combine like terms.
9m = 72
Divide both sides by 9.
m = 8

Answer:
Anton has $1.25 left.
Step-by-step explanation:
A dollar bill is worth $1.
A dime is worth $0.1.
A penny is worth $0.01.
How much Anton has?
4 pennies, 1 dime, and 2 dollar.
So he has 4*0.01 + 1*0.1 + 2*1 = 2.14.
Anton has $2.14.
He spends $0.89.
How much money does he have left?
2.14 - 0.89 = 1.25
Anton has $1.25 left.
Answer: m = - 3 and b = - 3.
Justification:
A system of linear equations will not have solutions if the two lines are parallel.
Two equations are parallel if their slopes (m) are equal and the y-intercep (b) are different.
Since the given equation is y = - 3x + 5, the value of m of the other equation, y = mx + b, in order to make a system with no solution, needs to be - 3, and the value of b need to be different to 5.
The only pair from the choices that meets that is the first option m = - 3 and b = -3.
