Write y = 3/5x + 4 in standard form using integers.
a) –3x + 5y = 20
b) 5x – 3y = 20
c) –3x – 5y = 20
d) –3x + 5y = 4

 Correct option is A) –3x + 5y = 20

Step-by-step explanation:

Standard form of general linear equation is

Given equation is

Now multiply both side of equation by 5

=>

Thus correct option is A) –3x + 5y = 20

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

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
