Answer:
I have solved the question in the picture in two different ways : simplification and factorisation I hope you find it useful bye:)
Hello!
no, that is not the correct way to isolate x. you were somewhat on the right track however.
here's the correct way:
add 7 to both sides to get -3x = -6
then divide both sides by -3 to get x = 2
I hope this helps, and have a nice day!
Answer: Width = 18m
Length = 32m
Step-by-step explanation:
Let the width of a rectangle be x
Let the length of the rectangle be: x+14
Width = 18m
Length = 32m
Check the attachment for the explanation and further details.
So that is what we call a ratio
and it would look like
Answer:
36, 45
Step-by-step explanation:
Using equations you get
because one number is 9 more than the other and the sum is 81. Simplifying you get,
. Divide both sides by 2 to get
. Remember this is only x so to get the other number you have to add 9 to 36 to get 45 as the other number.
