Subtract: a. 14 – 7 – 5 b. (35 – 20) – 3 c. 45 – (23 – 14) d. 56 – 32 – 5

a. 2

b. 12

c. 36

d. 19

Step-by-step explanation:

a. 14 – 7 – 5 = 14 - 12 = 2

b. (35 – 20) – 3 = (15) -3 = 15 - 3 = 12

c. 45 – (23 – 14) = 45 - (9) = 45 - 9 = 36

d. 56 – 32 – 5 = 56 - 37 = 19

Hope it helps.

Thank you..!!

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!
