No not all diagonal lines are lines of symmetry! Because if you take a piece of notebook paper and fold it in half the side do not match up! hope this helps :)
4x+7 would be your answer
In parentheses 6 times 3 plus three times 2 minus 2 back parentheses plus new parentheses x times 3 minus 5 times 2 minus 3 equals 12.
there hope this helps!!
The answer is 60.60dollars
5/8 as a decimal would be 5/8 times 100/x because if you found the equivilent fraction you would be able to multiply it by the upside-down-fraction and get 1 for example 2/4 =1/2 if you multiply 4/2 with 1/2 you would get 4/4 or 1
so 5/8 times 100/x =500/8x=1
then use long division to solve 62.5/100=62.5%
