1. 2(4) - 4y = 20
8 -4y = 20
8-8 -4y = 20 - 8
-4/-4y = 12/-4
y = -3

Answer:
102 mg
Step-by-step explanation:
Let's convert 28 pounds to kgs.
Since 1 kg = 2.2 pounds, we can find:
So 28 pounds is 12.73 Kg
Since 8mg is given per kg, for 12.73 kg, the amount given should be:
12.73 * 8 = 101.84
Rounded to nearest whole number, that is, 102 mg
Answer:
Total number of outcomes = 23
number of biology and art students = 2
number of biology students = 2
Since it is given that all the students study art,
number of possible outcomes = 2
probability = number of favorable outcomes/number of total outcomes.
= 2/23
Therefore probability that the selected student studies both art and biology is 2/23.
Answer:
5.7 meters
Step-by-step explanation:
Image a rectangle being cut diagonally in half, that would lead to two triangles. We can use the pythagorean theorem to find the missing side.
7 is the hypotenuse and 4 is the side length
4^2+x^2=7^2
16+x^2=49
sqrx=sqr(49-16)
x=sqr33
x=5.74
Rounded to the nearest tenth is 5.7
