Ok, I'll make it simple for you: Keep Change Change. For all subtraction problems (and only subtraction, no addition), all you have to do is keep the first number, then change the sign from a minus to a plus, and then change the last number to the opposite. For example:
7 - (-3)
7 + 3=10

-4 - 10
-4 + -10= -14

For addition, if both numbers are negative, you just add them together. For example:
-21 + (-13)= -34

In this case you switch the sign and the number's sign also:
7 + (-18)
7 - 18 = -11

I hope I was help!!!

Mary knits scarves and sweaters to sell. Scarves take 2 hours to knit and sweaters take 10 hours. Mary would like to spend no mo

sveticcg [70]

Answer:

The system of inequalities is

$2x+10y\leq 40$

$x+y\geq 5$

The solution in the attached figure

Step-by-step explanation:

<u><em>The question is</em></u>

Write a system of linear inequalities.

Le

x ---> number of scarves knitted per week

y ---> number of knitted sweaters per week

we know that

Mary would like to spend no more than 40 hours per week knitting

The word "No more" means "less than or equal to"

so

$2x+10y\leq 40$ ----> inequality A

Mary would like to knit at least 5 items per week

The word "at least" means "greater than or equal to"

$x+y\geq 5$ ----> inequality B

Solve the system by graphing

The solution is the triangular shaded area

1 Draw the Venn diagram below. Write the numbers 8, 9, 10, 11, 12 and 13 in the correct places on your Venn diagram. multiples o

iragen [17]

Venn diagram is the representation of set in a graphical form

<em>See attachment for the set of multiples of 2, 13, 3 and 6 </em>

Given

$Numbers = \{8,9,10,11,12,13\}$

Let

<em /> $A \to$ <em> Multiples of 2</em>

<em /> $B \to$ <em> Multiples of 8</em>

<em /> $C \to$ <em> Multiples of 6</em>

<em /> $D \to$ <em> Multiples of 13</em>

<em />

First, we split the numbers in set of the given multiples

$A: \{8, 10, 12\}$

$B = \{8\}$

$C =\{12\}$

$D = \{13\}$

Digit 9 does not belong to any of these set

<em />

<em>Set B and set C are proper subsets of set A.</em>

This means that sets B and C will be inside set A in the Venn diagram

So, we have:

$A = \{B,10,C\}$

Since 9 does not belong to any of the sets, it will not be inside any of sets A, B, C or D

See attachment for the required Venn diagram
