Question

For some reason i can't post these individually. Pease help ASAP.

Answer 1

I can give you a tip :D

when solving these problems , use PEMDAS

PEMDAS stands for.... parenthesis; exponents; multiplication; division; adding; and subtraction

you use PEMDAS for the order of operations

for example~ number one says, 4 + 7 x 3 - 1

since there are no parenthesis or exponents you just do multiplication
7x3=21
so your new expression will be 4 + 21 - 1
4 + 21 = 25
25 - 1 = 24
your answer is 24
for multiplication, division, subtraction or addition, it all depends on the order it’s in. if the expression would say 2 - 1 x 7 + 1 instead of adding first, you would subtract
same thing goes for multiplication and division. if the expression says 2/1 x 1 , you would divide 2/1 first, then multiply

hope this helps :)))
stay safe!! <3
