Lamy can paint 84 portraits in 6 weeks. at this rate , how many portraits can he paint in 2 weeks
lilavasa [31]

Answer:

28 portraits

Step-by-step explanation:

Let's first figure out how many portraits Lamy can paint in 1 week, which is his <u>unit rate</u>. To calculate this, we just have to divide the number of portraits he paints by the amount of time it takes him to paint them.

In this case, the former quantity is 84 portraits, and the latter quantity is 6 weeks, so his unit rate is \frac{84 \text \: portraits}{6 \text \: weeks} = 14 paintings per week.

Now, we know that in 1 week, Lamy can paint 14 portraits. Therefore, since this is a <u>directly proportional relationship</u>, all we have to do to find how many portraits he can paint is 2 weeks is double the unit rate. This is because in a directly proportional relationship, if you multiply one variable by a number, you have to multiply the other by the same number to maintain equality, and here we are multiplying weeks by 2 so we need to multiply paintings by 2 as well.

Thus, Lamy can paint 14 · 2 = 28 paintings in 2 weeks.

Hope this helps!

Ashley has $9.05 in dimes and nickels. If she has a total of 108 coins, how many of each type does she have?
klemol [59]

Answer:

73\:\mathrm{dimes},\\35\:\mathrm{nickels}

Step-by-step explanation:

We can write the following system of equations:

\begin{cases}10d+5n=905,\\d+n=108,\\\end{cases}, where d is the number of dimes she has and n is the number of nickels she has.

Multiply the second equation by -5 and add both equations to solve for d:

\begin{cases}10d+5n=905,\\-5d-5n=-540,\\\end{cases}\\5d=365,\\d=\fbox{$73$}.

Plug d=73 into any equation to solve for n:

73+n=108, \\n=\fbox{$35$}
