Answer:
6
Step-by-step explanation:
So we have a number (let's call it x) and it was multiplied by 8 and added by 2. Therefore:
And we are told that the sum is equal to the product of 2 and 25 (or 50). Thus:
To find the number, we just need to find x. Thus, subtract 2 from both sides:
Divide both sides by 8:
And we're done!
So, our original number was 6.
If your school is 30 feet tall and 1 feet is 1.26 cm, you would multiply 30 and 1.26 to get the height of the scale model which is 37.8 cm. Then, if each toothpick is 6.3 cm, you would take 37.8 and divide it by 6.3 to get the number of toothpicks you need to build the school, which is 6.
The model will be 6 toothpicks tall.
