63

Step-by-step explanation:

First do every thing like pemdas do the exponents so 15-2^3-24/3+4^3 then it would be 15-8-24/3+64

15-8-24/3=-1

-1+64= 63

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

why are you giving so many marks make your marks less and make a question list so that i can understand your question very nicely
