U will use the pemdas method which is if u check parentheses, exponents, multiplication, division, addition, subtraction. for ex. say the expression is 5 + 30+ (5x10) u will check if u have any p, e, m, d, a, or s and do those steps in order. sometimes u will read left to right if it’s a divison first and then a multiplication
Well i atleast know its not 10 lol
If you search it up on google the answer pops up!!1
Answer:
520
Step-by-step explanation:
If you make it into a proportion where the percent of boys is 85% then you get 85/100=442/w. When you cross multiply you get 85w=44200. Then you simplify and get w=520 so there are 520 students in total
Answer:
First number --> x
Second number --> y
x + y = 14 --> x = 14 - y
x - y = 4
so
14 - y - y = 4
14 - 2y = 4
2y = 10
y = 5
so
x = 14 -5
x = 9
