Answer:
1
Step-by-step explanation:
4x dived by 2. X equals 2 -1(2) =1
First you would solve 4x=28. Divide both sides by 4 and you'll get x= 7. Then you plug in the 7 in replacement for the x in the equation, 29-5x and you'll get as an answer -6!!
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
4x-9=2x+5
4x-2x=9+5
2x=14
divide both sides by 2
x=7
