Number 2 is the problem i need help with
Reptile [31]

Answer:

2a) $180

2b) $1440

Step-by-step explanation:

2a) Basically Samuel works for 6 hours a day and earns 7.50 per hour, so you have to do 7.50 x 6 to see how much he earns per day (which in this case is $45). You then have to multiply $45 to 4 since he earns $45 per day and works 4 days per week (which is $180).

2b) After finding out how much he earns per week ($180 from the previous question), you then have to multiply $180 by 8 as $180 is the amount he earns per week and since he works for 8 weeks you have to multiply $180 by 8 (the answer is then $1440).

sorry if I'm not making sense, i tried :) good luck!

jasenka [17]

Answer: v=-18/5

Step-by-step explanation:

Assuming you want to solve for v, we need to use our algebraic properties.

\frac{v}{3}+2=\frac{4}{5}                 [subtract both sides by 2]

\frac{v}{3}=-\frac{6}{5}                    [multiply both sides by 3]

v=-\frac{18}{5}

Now, we know that v=-18/5.
