Tell me everything I need to know and please work out the problems

okay so the first one ull need to kno pemdas so start with the perenthesis (5^2-10) and then the exponent 2^3 and multyply thats by 5 and what ever answer u got in the perenthisis u divide by what u got with the second side of the problem

Step-by-step explanation:

if u need more help ill tutor u on it :)

Step-by-step explanation:

1. (5² - 10) ÷ 5 x 2³

= (25 - 10) ÷ 5 x 8

= 15 ÷ 5 x 8

= 3 x 8

= 24

2. a) 8.75 x 20 ( hrs )

= 175 a day

b) 175 x 5 ( 5 working days )

= 875 (in a week)

c) 875 x 8 ( 8 wks )

= 7,000

sorry, i can't understand your question. will later if you describe more clearly!
