Apply the distributive property to create an equivalent expression.
4 ( x-2+y)

4x - 8 + 4y

Step-by-step explanation:

The Distributive Property states the following:

a ( b + c + d ) = a(b) + a(c) + a(d)

Now we can insert the given equation into the formula above:

4 ( x - 2 + y ) = 4(x) + 4(-2) + 4(y)

Then simplify the equation:

4x - 8 + 4y

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
