Answer:

Step-by-step explanation:

Cost of a t-shirt = 150 grams

Cost of 20 t-shirts = 150*20

= 3000 gram { 1000 g = 1 Kg}

= 3000/1000 = 3 kilogram

3 1/3 - 2 2/5 what is the answer?

AURORKA [14]

One way to solve this is by changing the mixed numbers to improper functions.
3 1/3 = 10/3
2 2/5 = 12/5

The next step I would take is to find a common denominator.
10/3 = 50/15
12/5 = 36/15

Now we can solve the original equation:
50/15 - 36/15 = 14/15

Since 14/15 is already simplified this is your final answer.

What two numbers multiply to -320 and add to 32

iragen [17]

Let a and b be the numbers,then a+b=32,b=32-a
ab=-320
a(32-a)=-320
32a-a^2=-320
a^2-32a-320=0
a^2-40a+8a-320=0
a(a-40)+8(a-40)=0
(a-40)(a+8)=0
a=40 or-8
when a=40,b=32-40=-8
when a=-8,b=32-(-8)=32+8=40
so numbers are 40 and -8

Pls help me asap....thanks in advanve

You would at the distances together, since 120 is above sea level and 39 is below. To find the whole vertical distance (the distance they are apart), just add the values (numbers) together.

$120+39=159$

$159=the-distance$

I hope this helps!
