Answer:
1.7(12) + 3(-6) = 84 - 18 = 66
Answer:
3,444
Step-by-step explanation:
The art teacher had 1321 pipe cleaners for a project
She used 477 with the fourth age
A parent donated 2,600 pipe cleaners
Therefore the number of pipe cleaners she have left can be calculated as follows
= 1321-477+2600
= 844 + 2600
= 3,444

Step-by-step explanation:
Thank your for revising and improving the image.
Assuming DF is a straight line,
Given E is the mid-point of DF
mCE = mGF
CE || GF
Then
mDE = mEF (E midpoint of DF)
Angle DEC = Angle EFG (corresponding angle, DF transversal of parallel lines CE and GF)
mCE = mGF (given)
Then triangles DCE and EGF are congruent by reason SAS (side-angle-side)
8/11 is the answer
I use this trick: When tryig to find repeating numbers divide by 11 or 9
When dividing by 9 the numerator will be the first number in the decimal
When dividing by 11 the numerator will be one more than the first number in the decimal
