Question

having trouble with math problems... ?

i've trying to do my homework but i really can't understand it.

i really do want to have high academic grades.

can anyone please help me to solve them?

evaluate each expression.

(4 t 6)7 50 -(15+ 9) 29 - 3(9 -4 )

[7(2) -4] + [9+8(4) ] (4x3)exponent 2 x 5

_________________

9 + 3

(16-3)x4 15+3x2 22+3x7 4(11+7) - 9 x8

12(9+5) -6x3 12 divided by 3x5-4 exponent 2

15 divided by 3.5 - 4 exponent 2

288 divided by [3(9+3)]

390 divided by [5(7+6)]

2x8 exponent 2 - 2 exponent 2 x 8

_______________________________

2x8

4x6 exponent 2 - 4 exponent 2 x 6

____________________________

4 x6

Answer 1

You say you want high academic grades, but then you ask us to basically do all of your math homework for you.

Doesn't work that way, sorry.

Maybe you could use a tutor.

Answer 2

(4 t 6)7 50 -(15+ 9) 29 - 3(9 -4 )

[7(2) -4] + [9+8(4) ] (4x3)exponent 2 x 5

9 + 3

is this order of operations?,then i can help you.

remember the key fact.

do this in order when u have to evulate an expression

P: arathesis: eg. (x-x)

E: xponent  :eg x^2

M: ultiply     :eg. x * x

D: ivide        : 4/2

A: dd           : eg. x+x

S: ubtract     :eg: x-x

but remember

paranthesis always go first!!!

exponents come second,if there are.

if there arent either of them,just skip to the next one.

(EG: (2+2) - 2 /3

no exponents,so just move on to divide.

so its 1 1/3

subtract or add could be done in any order.just them two.

multiply or divide could be done in any order.just them two also.

ummm the expressions are like messed up.so i do one of them that makes sense.

390 divided by [5(7+6)]

first: do the PARANTHESIS!!!! which is [5(7+6)]

so its now 390 divided by 45

no divide that and you get the answer

8.66666666666666666666666666 so on

Answer 3

You can obtain free on line help by teachers./

Two good sites are:

pathwhelp.com

Jiskha.com

Answer 4

I don't know what the t means in the first expression

Either way, you shouldn't be asking other people to solve your problems for you; it's not a very efficient way of living your life (not to be rude).

My advice is to consider a tutor.
