3. Twenty is two times the size of ten.
That's basically what the division problem says, is it not?
Let the x ml of water be mixed with 237 ml of ammonia whose strength is 100%, in order to create a mixture of 75% strength.
The equation required to solve this will be:
237/(237+x)=75/100
solving for x we get:
237/(237+x)=3/4
237×4=3(237+x)
948=711+3x
3x+711=948
3x=948-711
3x=237
x=237/3
x=79 ml
therefore the amount of water to be added will be 79 ml
Answer:
546
Step-by-step explanation:
4x3^7=2187
so now its
2187=4x+3
subtract 3 from both sides
now its
2184=4x
divide both sides by 4
546=x
