Juan needs to mix a 10% acid solution with a 50% acid solution to create 100 millileters of a 34% solution. how many millileters of each solution must juan use?
juan must mix
millileters of 10% solution and
millileters of 50% solution.

juan needs to mix a 10% acid solution with a 50% acid solution to create 100 millileters of a 34% solution.

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
