4. Evaluate the expression P+5-mn/2, for m=2, n=4 and p=1
a. 8
b. 4
c. 2
d. 6

And one more question

Answer 1

1 is B... the answer is simple, multiply 8 by the number of hours you work, so 8h then substitute 36 for the h, so multiply 36(8) = 288

Answer 2

a. 7p;4
b.28 (over) p;7
c. 4p; 28
d. p (over) 4; 7

Answer 3

The rest are really easy so you should b able to figure them out... for 2 for example just solve 84 + 3(2) since h is 2 you just substitute it in

Answer 4

I have math and reading dyslexia, and this is my first year of pre al, so this isn't easy for me.

Answer 5

Ok well this isn't a quiz or test or anything right?

Answer 6

no, it's just the ones I couldn't figure out from my book.

Answer 7

ok well do you understand what I said for #1 and #2?

Answer 8

yes.

Answer 9

ok so for #2 the one you thought was the right answer is not.... 3(2) is 6 so just add 6 to 84... 84 +6...so what do you get?

Answer 10

90.

Answer 11

yup! so there is your answer for 2... for #3 is that supposed to be a divided by 4?

Answer 12

yes

Answer 13

ok lets come back to 3...we will do #4 right now...

Answer 14

ok

Answer 15

A/4 for A=32
32/4 = 8

Answer 16

P+5-mn/2, for m=2, n=4 and p=1

1 + 5 - 2(4)
1 + 5 - 8
6 - 8
-2

Answer 17

P+5-mn/2, for m=2, n=4 and p=1
1+5-(2*4)/2
6-4
=2

Answer 18

oh wait 2 i meant 2

Answer 19

so the answer is 2?

Answer 20

yup

Answer 21

yes you should solve it like this
P+5-mn/2, for m=2, n=4 and p=1

1 + 5 - 2(4)/2
1 + 5 - 8/2
1 + 5 - 4
6 - 4
2

Answer 22

. p (over) 4; 7

Answer 23

so you solve going right to left?

Answer 24

Solve the multiplication/division part first....then do addition and subtraction

Answer 25

Ok

Answer 26

total no of people.=p
people in each group=4
total groups = p/4

Answer 27

have u learned PEMDAS?

Answer 28

In like, 3rd grade. I don't remember tho

Answer 29

if p=28
then total groups= 28/4 = 7

Answer 30

Parentheses, exponents, multiplication/division, and addition/subtraction

this is the order that you should solve equations

Answer 31

ok, thanks!

Answer 32
