Answer:

Option B. 1.8(2x + 7) – 15 = 3.6x – 2.4

Step-by-step explanation:

1.8(2x + 7) – 15

To know which option is correct, let us simplify the above expression. This can be obtained as follow:

1.8(2x + 7) – 15

Clear bracket

1.8(2x + 7) – 15 = 3.6x + 12.6 – 15

1.8(2x + 7) – 15 = 3.6x – 2.4

Thus,

1.8(2x + 7) – 15 is equivalent to

3.6x – 2.4

Find the value of f(-1) for the function below
mrs_skeptik [129]

Put the value of x = -1 to the equation of a function f(x):

f(x)=\dfrac{2}{3}\times3^{3x+12}\\\\f(-1)=\dfrac{2}{3}\times3^{3(-1)+12}=\dfrac{2}{3}\times3^{-3+12}=\dfrac{2}{3}\times3^9=\dfrac{2}{1}\times3^8=13,122\to\boxed{B.}

In one week, Alex worked 35 hours at $ 12.50 per hour plus 5 hours overtime at 'time and half'. How much would Alex have earned
zvonat [6]
Find out how much Alex earned in 35 hours first.

1 hour = $12.50

35 hours = $12.50 x 35 = $437.50

Since ‘time and a half’ pays 1.5 times more than their usual pay, find out how much Alex earned per hour at ‘time and a half’

1 hour = 12.50 x 1.5 = $18.75

5 hours = 18.75 x 5 = $93.75

$437.50 + $93.75 = $531.25

Alex would have earned $531.25 for the week.
