Try this option:
1. note, that the number 84 is divided by numbers: 1;2;3;4;6;7;12;14;21;28;42 and 84. It means, that measurements of the length may be: 1;2;3;4;6;7;12;14;21;28;42;84 and for the width: 84;42;28;21;14;12;7;6;4;3;2;1.
2. according the numbers calculated in item 1, the possible number measurements for the length and width of the sandbox are (length; width):
1;84
2;42
3;28
4;21

A department store sold 67 shirts one day. All short sleeved shirts cost $15.00 each and all long sleeved shirts cost $26.00 eac
earnstyle [38]

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

s+l = 67\ \ \ Eqn\ 1\\15s+26l = 1335\ \ \ Eqn\ 2

From eqn 1:

s = 67-l

Putting in equation 2:

15(67-l)+26l = 1335\\1005-15l+26l = 1335\\1005+11l = 1335\\11l = 1335-1005\\11l = 330

Dividing both sides by 11

\frac{11l}{11} = \frac{330}{11}\\l = 30

Putting l=30 in equation 1

s+30 = 67\\s = 67-30\\s =37

Hence,

37 short-sleeved shirts were sold and 30 long-sleeved shirts were sold

Mila plants 820 hectares of potatoes and corn. To maximise his profit he plants 140 hectares more of potatoes than of corn. How
nadya68 [22]

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.

I want to know the answer to his question
Goshia [24]

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.

{b}^{2} +  {b}^{1}  +  {b}^{2}  +   {b}^{1}

see all the numbers above the B's? add them all

2 + 1 + 2 + 1

And you get 6

now take one of your Bs and slap the six on like so

{b}^{6}

and there's your answer
