Answer:

  • 8 small paintings
  • 4 large paintings

Step-by-step explanation:

If all 12 had been small paintings, DeGuizman's revenue would have been $720. At $1200, it is $480 more than that. Each large painting generates $120 more revenue than a small painting, so there must have been $480/$120 = 4 of them sold.

8 small paintings and 4 large paintings were sold.

Refer to the number line. Find the coordinate of point D that is 7/16 M to J. of the distance from M to J.​
Usimov [2.4K]

The coordinate of point D that divides segment MJ in the ratio 7/16 is (13, 8)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Let us assume that point M is at (20, 1) and point J is at (4, 17), hence:

If point D(x, y) is 7/16 M to J, then:

x = (7/16)(4 - 20) + 20 = 13

y = (7/16)(17 - 1) + 1 = 8

The coordinate of point D that divides segment MJ in the ratio 7/16 is (13, 8)
