Astaining solution bottle in a medical laboratory contains 30 ounces .a blood staining test requires 3/4 of solution a tissue staining test requires 1/2 oz of solution if for blood tests and five tissue tests are performed how many ounces of solution are left in the bottle

5 ounces of solution are left in the bottle.

Step-by-step explanation:

Volume of the staining solution, s = 30 oz

Volume required for the blood staining test = of solution

Volume required for blood tests =

Number of blood staining tests run = 1

Volume of solution required in 1  blood staining test ,x= 22.5 oz × 1 = 22.5 oz

Number of blood test run = 5

Volume of solution required in 5 blood test ,y= 0.5 oz × 5 = 2.5 oz

Volume of staining solution left : s - x- y

= 30 oz - 22.5 oz - 2.5 oz = 5 oz

5 ounces of solution are left in the bottle.

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
