Answer:
Picture 1: 40 degrees
Picture 2: 90 degrees
Picture 3: 65 degrees
Picture 4: 85 degrees
Step-by-step explanation:
(2x-5) + (x+25) + (x) = 180
4x=160, x=40
180-90 = 90
2(65)+12+38 = 180
2x=40, x=20
6(20)-25 = 95
180-95 = 85

Answer: 2.5 mL
Step-by-step explanation:
Given : A patient is given a solution containing 0.625 g of calcium carbonate.
i.e. Patient required calcium carbonate = 625 mg [∵ 1 g = 1000 mg]
Let x be the amount of solution ( in millimeters) given to the patients.
Ratio of amount of calcium carbonate (mg) to amount of solution (ml) =
If the calcium carbonate solution contains 1250 mg per 5 mL,
Then, Ratio of amount of calcium carbonate to amount of solution =
By using proportion we have :-
Hence, 2.5 mL solution were given to the patient.
