37 short-sleeved shirts were sold and 30 long-sleeved shirts were sold
Step-by-step explanation:
Let s be the number of short-sleeved shirts
and
l be the number of long sleeved-shirts
Then according to given statements
From eqn 1:
Putting in equation 2:
Dividing both sides by 11
Putting l=30 in equation 1
Hence,
37 short-sleeved shirts were sold and 30 long-sleeved shirts were sold

Answer:
480 Hectares potatoes, 340 Hectares corn
Step-by-step explanation:
Let x be the land used to plant potatoes in hectares.
Let y be the land used to plant corn in hectares.
Given the information from the question, we know that:
x + y = 820 - Equation 1
and
x - y = 140 - Equation 2
as you can see here we have 2 equations, means we can solve them simulteanously to solve for both. We will use elimination method.
We will use Equation 1 - Equation 2.
x-x+y-(-y)=820-140
2y = 680
y = 680 ÷ 2 = 340 hectares
We substiture y into equation 1 to find x
x + 340 = 820
x = 820 - 340
= 480 hectares
Therefore, 480 hectares of potatoes and 340 hectares of corn were planted.
the answer was d(3d-10)
let's show your the factor
3d^2-10d
d(3d-10)

So if the package costs $4, and there are 8 pens, how much does each pen cost?
ok, maybe you really don't know how to do this, but this is just being plain lazy. any way,
see the B's that have a little 2 on them? image that the other B's also have the same thing, but it's a one.
see all the numbers above the B's? add them all
And you get 6
now take one of your Bs and slap the six on like so
and there's your answer
