If someone could help me with it would be greatly appreciated. A scientist has two solutions, which she has labeled Solution A a

Talja [164]

Answer:

16 for Sol A and 24 for Sol B

Step-by-step explanation:

Let x = the number of ounces of Solution A

Let y = the number of ounces of Solution B

x + y = 40 y = 40 - x

.60x + .85y = .75(40)

.60x + .85y = 30 Multiply both sides of the equation by 100 to remove the decimal points.

60x + 85y = 3000

60x + 85(40 - x) = 3000

60x + 3400 - 85x = 3000

-25x = -400

x = 16 ounces

y = 40 - 16

y = 24 ounces

Papessa [141]

Age of Sita is 14.25 years and her father is 42.75 years

Step-by-step explanation:

Step 1: From given details, let present age of Sita be x and that of her father be 3x.
Step 2: Form equations based on their ages in 6 years. (Given sum is 69)

⇒ (x + 6) + (3x + 6) = 69

⇒ 4x + 12 = 69

⇒ 4x = 57

⇒ x = 14.25
