Shana and Marie will update parts of their computer system. They will update the motherboard for $259.99,
2 USB ports for $39.95 each, and the DVD drive for $79.49.
Shana will save $12.50 per week and Marie will save
$15.50 per week. Which inequality can be used to find w,
the number of weeks it will take Shana and Marie to save
enough money for the parts?

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

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!

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
