M to the 3 power + 9n when m = 4 and n =5

109

Step-by-step explanation:

m to the power of 3 can be mathematically  written as

m³

we have

= m³ + 9n

note that we were provided with the values of m and n to be m=4 and n = 5 respectively.

so from

=m³ + 9n

=4³ + 9 × 5

=64 + 45  ( we arrived at 64 by multiplying 4 in three different places i.e 4 × 4×4)

=109

therefore M to the 3 power + 9n when m = 4 and n =5 is caculated to be equals to 109

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!

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
