Question

Evaluate the expression btw it 3 questions and if you don’t mind can I have an explanation because I don’t know how to evaluate the expression it would really help numbers bellow
1) 5x3 + 5x12

2) 4+ 8 divided by 2

3) 45 divided by 5×3+2

Answer 1

1. 5x3 will be 15 (5+5+5) and 5x12 will be 60 (5+5+5+5+5+5+5+5+5+5+5 +5) so 15+60=75


2. 4+8 divided by 2. First you do 8 divided by two because it pemdas, parenthesis, exponents, multiplication, division, addition, and subtraction. Now you’ll have 4+4=8


3. 45 divided by 5x3+2


First you divide 45 and 5 since it’s comes first in the equation, even though multiplication is before division, you divide, since it’s first, so now your left with 9x3+2

9x3= 27

27+2= 29
