AOB = 2 . x
2x = 60°
x = 30°
If you are solving for X then we have to do a few process
What you would want most is to remove the parentheses, so to do that i would use distributive property
3*2x is 6x and 3*3 is 9 so our new equation will look like
6x+9=15 if you don't understand please tell me
now we must bring the 9 over
If you bring the 9 over than it would become negative
6x=15-9
so 6x=6
and now you can solve the answer is x=1
-7x+-4y (I think- it depends on the topic)
teacher has 0.4 L of sea water , it means 0.4*1000 ml = 400 ml of sea water , she has.
Now every student has 5 ml spoon with them and there are a total of 20 students.
The teacher has asked every student to put 2 spoons of seawater into their container .
Now 1 spoon = 5ml
2 spoon = 10 ml
22 students are there it means
there are 44 spoons.
44 spoons = 44* 5 ml = 220 ml
It means Student put 220 ml seawater in total
And Teacher had 400 ml.
Now , Teacher is left with = 400 - 220 = 180 ml
