Answer: 0.24
Step-by-step explanation:
You have to multiply the percent by its decimal form and then you multiply the decimal by the cost of the meal
8²+9(12÷3×2)-7
well we are going to start in the parentheses and do order of operations
so 12÷3=4
then 4×2=8
so you have 8² +9(8)-7
well we still need to get rid of the parentheses 9×8=72
so then we are left with 8²=72-7
so now we have to get rid of the exponents so8²=64
64+72-7
136-7=129
so 129 is your answer to the first one.
the second one is easy. its a single step equation.
you are trying to get x by itself. so you have 7x=42. you want to get rid of the seven so you have to do the opposite of what it is doing to x. the 7 is multiplying by the x. So whats the opposite of multiplication... division. so you have to divide both sides by 7. so you have 7÷7x=42÷7
now simplify and you have x=6
