Answer:
The scale that Leon used to create the scale drawing is 1:72.
Step-by-step explanation:
Given that Leon created a scale drawing of the school library in his art class, and in the scale drawing, the length of the library is 13 inches while the length of the actual library is 78 feet, to determine which scale did Leon use to create the scale drawing of the school library, the following calculation must be performed:
1 foot = 12 inches
78 feet = 12 x 78 = 936 inches
936/13 = 72
So, the scale that Leon used to create the scale drawing is 1:72.
Answer:
Use y + x = 3 and solve for either x or y.
Step-by-step explanation:
Substitution is a method to solve a system of equations by substituting an expression from one equation into the other.
To begin, first solve one equation by isolating for one variable. Choose the equation which will have the least number of steps to do so.
y + x = 3 can be solve for x or y by subtracting the other variable. Since this only requires one step use this equation. Either variable can be used.
