Question

Tegan needs to make 686868 more snow blocks to finish building an igloo. Write an equation for the number of blocks Tegan still needs to make, mmm, when she has completed ccc blocks. Tegan completes 333333 blocks. How many blocks does Tegan still need to make to finish the igloo?

Answer 1

Answer:

m = 68 - c ; 35

Step-by-step explanation:

Given the following :

Number of blocks Tegan needs to make = 68

Number of blocks completed = c

Number of blocks left to make = m

Therefore, the number of blocks 'm' left to make is given by the equation :

(Total number of blocks needed - number of blocks completed) = number of blocks left to make

(68 - c) = m

Equation : m = 68 - c

If completed blocks 'c' = 33 ; number of blocks needed to complete the igloo :

From m = 68 - c

m = 68 - 33

m = 35
