Answer:

R\left(\frac {4x_1+3x_2}{7} , \frac {4y_1+3y_2}{7}\right)

Step-by-step explanation:

Let the coordinate of the points W, V and R are (x_1,y_1), (x_2,y_2), and (x_s,y_s)respectively.

The coordinate of the section point, (x_s,y_s), which divides the line joining the two points (x_1,y_1) and (x_2,y_2) in the ration m:n is

x_s=\frac {nx_1+mx_2}{m+n} and

y_s=\frac {ny_1+my_2}{m+n}.

The given ration is, m:n=3:4

R(x_s,y_s)=R\left(\frac {nx_1+mx_2}{m+n} , \frac {ny_1+my_2}{m+n}\right)

=R\left(\frac {4x_1+3x_2}{7} , \frac {4y_1+3y_2}{7}\right).

The exact point can be determined by putting the value of the exact coordinate in the above-obtained formula.

Answer: C=5L+25
12 lunches cost $85

Explanation:
“Fancy lunch for $5 each” the key word: each, tells us that one lunch cost $5
Since he is buying 12 lunches you would need to multiple 5 by 12 to get 60 dollars.

The $25 is the amount of money to join the lunch club, so that mean you would need to add that to get the total money he spend.

Equation would be C=5(12)+25
12= lunches he bought

Find r when (5)* r/3 = 125.
Dima020 [189]

Answer:

5 to the power of 3 is 125, so since the denominator is 3 you need a  numerator that will simplify to 3.

9 divided by 3 equals 3, so your numerator will be 9.

Hope it helps!
