Could someone meee so bad at this .

the numerical expression 8+ 12 ÷4 was evaluated in two different ways resulting in different values

solution a
8+12÷4
20 ÷4
5

solution b
8+12÷4
8+3
11
which is correct ? explain how you know .

A

Step-by-step explanation:

you only use opposite of order of opperations with algebra

so you would do the 12/4 first then add 8. if this was an algebaic equation add 8 first. but this is a normal equation

Step-by-step explanation:

it would be helpful to know bedmas

B brackets        <= you figure out brackets first

E exponents                          then exponents

D division                                    then division

M multiplication                               then multiplication

A addition                                              then addition

S subratraction                                            then subtraction

so the numerical expression 8+12÷4 =

8+3=11

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5

you.
