Answer:
x = 12
Step-by-step explanation:
7x=8x-12
take away the 7x from both sides
0=x-12
add 12 to each side
12=x
check it
7(12)=8(12)-12
84=96-12
84=84
increase the speed is definitely the answer
Answer:
3 minutes; 27 minutes; 30 minutes
Step-by-step explanation:
Let the common multiplier of the given ratios be x. So, the ratios 1: 9 : 10 will become x, 9x and 10x respectively.
Therefore,
![x + 9x + 10x = 1 \: hour \\ \\ 20x = 60 \: minutes \\ \\ x = \frac{60 \: minutes}{3} \\ \\ x = 3 \: minutes \\ \\ 9x = 9 \times 3 = 27 \: minutes \\ \\ 10x = 10 \times 3 = 30 \: minutes](https://tex.z-dn.net/?f=x%20%2B%209x%20%2B%2010x%20%3D%201%20%5C%3A%20hour%20%5C%5C%20%20%5C%5C%2020x%20%3D%2060%20%5C%3A%20minutes%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B60%20%5C%3A%20minutes%7D%7B3%7D%20%20%20%5C%5C%20%20%5C%5C%20x%20%3D%203%20%5C%3A%20minutes%20%5C%5C%20%20%5C%5C%209x%20%3D%209%20%5Ctimes%203%20%3D%2027%20%5C%3A%20minutes%20%5C%5C%20%20%5C%5C%2010x%20%3D%20%2010%20%5Ctimes%203%20%3D%2030%20%5C%3A%20minutes)
Thus, 1 hour in the ratio 1 : 9 : 10 can be divided as:
3 minutes; 27 minutes; 30 minutes
8 can go into 12 only once.
