A veterinarian examined 4 times as many dogs as cats today. In all, he examined 15 dogs and cats. Let d represent the number of dogs and c represent the number of cats that the veterinarian examined.

Use the labels to complete the bar diagram that models the situation.

Use the bar diagram to set up and solve a system of equations. How many dogs and cats did the veterinarian examine today?

In one volleyball game, Naomi had 3 times as many spikes as Vicki. Together, they had 20 spikes. How many spikes did each player have? Write and solve a system of equations.

\(\text{p} - 12 = 20\)

\(31 = \text{r} - 36\)

\(\text{m} + 1\cfrac{3}{8} = 5\)

\(56.9 = 34 + \text{p}\)

\(0.97 + \text{a} = 2.6\)

\(\text{x} - 24 = 73\)

\(\text{t} + 5 = 30\)

\(\text{r} - 15 = 63\)
