We are given some tables showing the number of stories completed in the construction of four different high-rise buildings and the number of days spent working on the building.

We are to determine whether which table represents a linear relationship.

Table B represents a linear relationship since its ratio of number of days to number of stories completed is constant.

Number of Days    120  240  360  480  600

Answer:

m∠MBT = 28°

Step-by-step explanation:

Since m∠NBM = m∠MBT, the 2 equations are equal to each other.

Step 1: Set up equation

17x - 6 = 5x + 18

Step 2: Solve for <em>x</em>

12x - 6 = 18

12x = 24

x = 2

Step 3: Find m∠MBT

m∠MBT = 5x + 18

m∠MBT = 5(2) + 18

m∠MBT = 10 + 18

m∠MBT = 28°
