Dawn ate 6 grams of chocolate.
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Dawn bought 12 grams of chocolate.
Here, She ate half of the chocolate.
Hence, The amount of eat chocolate = 12 / 2 grams
= 6 grams

Answer:
Hence, beginning time is:
9:38 a.m.
Step-by-step explanation:
We know that:
" Elapsed time is the time or difference between a beginning time and an ending time "
Here we are given that the ending time is:
10:08 a.m.
and elapsed time is:
0:30 minutes.
This means the beginning time will be :
ending time - elapsed time.
Hence on counting back 30 minutes from 10:08 am we get the beginning time as:
9:38 a.m.
We have to subtract 30 minutes from 10:08 am, then the elapsed time will be 9 hours 38 minutes.
It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.
Ending time: 10:08 am elapsed time: 30 minutes. Then the time will be
We know that elapsed means before 10:08 am. So we have to subtract 30 minutes from 10:08 am. Then we have
Then the time will be 09:38 am.

Answer:
x= -2
Step-by-step explanation:
sorry dont read this
Answer:
x= -2
Step-by-step explanation:
-2x-7=3(4x+7)
multiply numbers in parenthesis by 3
-2x-7=12x+21
move terms
-2x-12x=21+7
subtract -2x to -12x but since there negative the equation is addition. Also, add 21 to 7
-14x=28
divide both sides by -14
x= -2
Halle uses 67 cm of the green ribbon to wrap a present.
How much green ribbon is left?
The green ribbon is 96 cm long and if 67 cm of the green ribbon is used to wrap a present, the amount left is 29 cm
An equation is an expression that shows the relationship between numbers or variables.
Let x represent the length of the green ribbon.
The green ribbon is 38 cm longer than the blue ribbon, hence:
x = 58 cm + 38 cm
x = 96 cm
The green ribbon is 96 cm long.
If 67 cm of the green ribbon to wrap a present, the amount left is:
Amount left = 96 cm - 67 cm = 29 cm

Answer:
Option 1
Step-by-step explanation:
We will find the solution for the expression in option 1
Hence, x=1 and x=-4 willl be the solution
Hence, will be in denominator.
Hence, Option 1 is correct
Option 2,3 and 4 are discarded.
