Adeline is x years old Write down an expression for:
1. Adeline’s age in 10 years time
2. Adeline’s age 6 years ago

a.) x + 10

b.) x - 6

( i think )

Step-by-step explanation:

adeline is x years old so they can be any age really . 10 , 12 , 27 . etc .

in ten years she will be her age now ,, PLUS another ten years so it is x + 10

same for part b . except it is six years ago therefore take away . x - 6

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

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!
