6z -4 - z + 10 = -9
Combine like terms
5z + 6 = -9
Subtract both sides by 6
5z = -15
Divide both sides by 5
z = -3
Have an awesome day! :)
Given parameters:
Total length of curtains bought = 20m
She used 8m for the living room
She used 7m for the dining room
unknown:
Quantity used for the kitchen = ?
Solution:
Quantity used for the kitchen = Total length - (living room + dining room)
Input the parameters given solve;
Quantity used for the kitchen = 20 - (8 + 7) = 5m
The length of curtain used for the kitchen is 5m
Well the answer would be 12.5. I hoped that this helped. :)
Answer:
SSS means Side-Side-Side.
The reason JKM and LKM are congruent is because if you follow them each side will be equal to the other triangles angles if they're congruent
Step-by-step explanation:
When you translate the problem into mathemathical equation it will give
x is the number of 1$
y is the number of 5$
z is the number of 10$
2y=z+z
x+5y+10z=893
then you solve the equation and get the answers.
