Write each expanded form as a decimal. (5×10)+2+9×1/10+6×(1/100)+3×(1/1000

52.963

Step-by-step explanation:

Simply evaluate the expression. If you can't do it in your head, you can ask a calculator to do it.

(5×10)+2+9×1/10+6×(1/100)+3×(1/1000) = 50 + 2 + 9/10 + 6/100 + 3/1000

... = 50 + 2 + 0.9 + 0.06 + 0.003

.. = 52.963

20

step-by-step explanation:

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.

sorry if it was confusing!
