tamaranim1 [39]

Answer:

Step-by-step explanation:

Parts + 3($40 labor)=183.30

parts + 120=183.30

parts=63.30 but it includes tax. To find costs of parts before tax you

63.30/1.055=60 so parts are $60

or to solve with one equation:

parts(1.055) + 3($40 labor) = 183.30

parts(1.055) + 120=183.30

parts(1.055)=63.30

Parts = 63.30/1.055

parts = 60

PLEASE HELPPPP MEEEE NOWWWW!

Ket [755]

Answer:

2, 6, and 7

Step-by-step explanation:

3n is by itself because theres no other numbers that have the letter n.

6m and -11m are like terms bcs they both have the letter m (variable)

-3 and -18 are both like terms bcs they are both just numbers (or constants whatever)

so you would choose options 2, 6, and 7! hope this helps! :)

Can someone help me please

Alex73 [517]

Answer:

$15t > 180$

Step-by-step explanation:

the girl is selling tickets for dollars 15 and she wants to raise more than dollars 180. that means we need a symbol that will make it so that $180 is always less than. like such.

$180 < y \\ y > 180$

it shouldn't be less than or equal to symbol because she wanted to save more than $180. that means we can't use this expression.

$15 + t \geqslant 180 \\ 15t \geqslant 180$

and we can't use this expression either

$15 + t > 180$

let's say if we had somebody by one ticket then that would mean we would add 1 to 15 which will equal 16 and so forth.

$15 + 1 = 16 \\ 15 + 2 = 17 \\ 15 + 3 = 18$

etc....

if each one of her tickets cost $15 and t is equal to the amount of tickets sold then we should multiply the operation so that we have groups of 15. like such.

$15 \times 1 = 15 \\ 15 \times 2 = 30 \\ 15 \times 3 = 45 \\ 15 \times 4 = 60$

etc....

this means the expression she wants to use is

$15t > 180$

if you want more help you can ask me and I will try to answer your questions.
