Simplify each expression

1) 3x + 6x + 5

2) 7(2x)

3) 4(8x + 3y)

1.) 9x+5

2.)14x

3.)32x+12y

Step-by-step explanation:

for the first problem, you combine the x terms because they are like terms. the the second and third problems you apply the distributive property.

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

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
