A scientist is working with two different concentrations of hydrochloric acid (HCl). One bottle is 80%, and the other is 30% HCl. For their experiment they need 1 liter of 60% HCl. How many liters of the 80% solution do they need? How many liters of the 30% solution?

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

x = -5

step-by-step explanation:

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
