Answer:
1) 4x + 4y = -8
x=-2-y
y=-2-x
2) 22 – 2y = 4
y=9
Step-by-step explanation:
To find the base area of a pyramid, you can use the equation:
volume = base area × height
volume = 10 × 9
volume = 90 cubed inches
Answer:
We conclude that the number of milligrams of the vitamin in the drink will be: 48 mg
Step-by-step explanation:
The amount of certain Vitamin = 40 mg
Given that a new health drink has 120% of the recommended daily allowance (RDA) for a certain vitamin is 40 MG.
Thus,
The number of milligrams of the vitamin in the drink:
120% of 40
= [120/100] × [40]
= 1.2 × 40
= 48
Therefore, we conclude that the number of milligrams of the vitamin in the drink will be: 48 mg
