Evaluate the expression.
4(11 + 7) – 9.8

62.2

Step-by-step explanation:

The order you must follow is Brackets, Division, multiplication,  subtraction.

First, you solve the expression in the brackets.

4(18)-9.8

Then you multiply since there is no division involved here.

72-9.8

And lastly, you subtract

62.2

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.
