<span>4x+2(3x-9)=42
first we want to distribute the 2 using the distributive property
4x+6x-18=42
Then we simplify
</span><span>10x-18=42
we add 18 to both sides
10x=60
divide both side by 10
x=6</span>

Answer:
$105.5 for 16 hours at $6.59 per hour
Step-by-step explanation:
form the equation given, G=h(t) + p(c)
where G=Gross pay,
h= hourly wage
t=time worked
p=percent tip
c=cost of customer meals
we determine the gross pay by first determining the independent variables
h=$4.25, t=16 hours,

if we substitute values, we arrive at

to determine the per hour gross pay we have
105.5/16
hourly gross pay,G=$6.59
Answer:
19.63%
Step-by-step explanation:
The probability of scoring 8 points is the probability of getting a dart into the green circle.
That probability is equivalent to the area of the circle divided by the total area of the square board.
The area of the circle according to
, is
cm squared
The area of the whole square board is one side squared: 20 squared = 400 cm squared
The probability is therefore equal to
%
