6 0

Answer:

Step-by-step explanation:

-4x + 2y = -30

-2x + 2y = -10

-4x + 2y = -30

 2x - 2y = 10

-2x = -20

x = 10

-2(10) + 2y = -10

-20 + 2y = -10

2y = 10

y = 5

(10, 5)

Add. -6 + (-73) + 56 + (-33)<br> a.-168<br> b.-56<br> c. 10<br> d. -44
Nadusha1986 [10]

Answer: -56 or b.

Step-by-step explanation: -6+(-73)=-79 because the negative number means minus.

-79+(positive)56=-23 because a negative number plus a positive number is adding the positive number meaning you subtract but keep the negative sign

-23+(-33)=-56 because the negative number means minus

I don't know how to explain that is just kind of how it works.

But here's something for the future.

Positive+(Negative) is minus

Positive+Positive is plus (duh)

Negative plus negative is minus (or add but theres a negative sign)

Negative-negative=plus (idk why but its meth)

A copy machine can print 480 copies every 4 minutes. How many copies can it print in 10 minutes? :)
wariber [46]

Answer: 1200

Step-by-step explanation:

since every 4 minutes it can make 480 copies

Peisonally I would divide to see hou uch it could make in ONE minute

so 480/4 = 120

so it makes 120 copies per minute

now simply multiply by 10

120 x 10 = 1200 copies.

hope this helps! :)
