Darryl wants to add enough water to 8 gallons of a 10% bleach solution to make a 5% bleach solution. Which equation can he use to find x, the number of gallons of water he should add? Original (Gallons) Added (Gallons) New (Gallons) Amount of Bleach 0. 8 0 0. 8 Amount of Solution 8 x 8 x StartFraction 0. 8 Over 8 x EndFraction times StartFraction 5 Over 100 EndFraction = 1 StartFraction 0. 8 Over 8 x EndFraction times = StartFraction 5 Over 100 EndFraction StartFraction 0. 8 Over 8 x EndFraction = StartFraction 100 Over 5 EndFraction StartFraction 0. 8 Over 8 x EndFraction divided by StartFraction 5 Over 100 EndFraction = 1.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
