Answer:

Step-by-step explanation:

Since we have given that

Number of styrofoam balls bought by Bradley in May = 48

Number of toy figurines sold in May = 19

Number of styrofoam balls bought by Lupe in June = 44

Number  of toy figurines sold in June = 21

So, we need to make a matrix that represents all of their May purchases and their June sales :

So, it is given by

                       May                    June

                    Purchases             Sales     

 Bradley       48                            19

 Lupe            49                           21

Thus, we can define a 2x2 matrix in which row 1 represents Bradley and row 2 represents Lupe. The columns then represent May and June. To distinguish between purchase and sale, we will show sale by a positive number and sale with negative; therefore the final matrix will be

\left[\begin{array}{ccc}48-19\\44-21\end{array}\right]

Number of styrofoam balls bought in May = 48

Number of toy figurines sold in May = 19

Number of styrofoam balls bought in June = 44

Number  of toy figurines sold in June = 21

                     Purchases             Sales     

 Bradley      48                            19

 Lupe           49                           21

Hence, the proper matrix will be

\begin{bmatrix}48 &19 \\ 49&22 \end{bmatrix}

In Aunt Melly's attics there are also spiders and ants, the total of 136 legs and 20 heads. If a spider has 8 legs and an ant ha
anzhelika [568]

Answer:

Spiders=8

Ants=12

Step-by-step explanation:

Spider(s)=8 legs

Ants(a)=6 legs

Total legs=136

Total heads=20

8s+6a=136 (1)

s+a=20 (2)

From (2)

s=20-a

Substitute 20-a into (1)

8s+6a=136

8(20-a)+6a=136

160-8a+6a=136

160-2a=136

-2a=136-160

-2a=-24

a= -24/-2

a=12

Substitute a=12 into (2)

s+a=20

s+12=20

s=20-12

s=8

Justin is asked to solve the following system of linear equations using the elimination method.
romanna [79]

Alright, lets get started.

Justin is asked to solve the linear equations using elimination method.

By using elimination method means we have to multiply some numbers in our given equations in such a way that the co-efficient of x or y become same in both equations so that we could add or subtract them to cancel one of the term either x or y.

So, given equations are :

5x - 12 = 3

-20x + 14 y = 13

See we have 5x in first equation and -20x in second equation.

So, we try to change 5x into 20 x by multiplying it with 4, both of the equations will have 20 x in common

Lets multiply 4 in first equation

4 * (5x-12y) = 4 * 3

20x - 48y = 12

Now both equations could be added and 20 x will be cancelled out and we could easily find the value of y then solve for x.

So, Justin should try to change 5 so that it will be cancels, so option B  :  Answer

Hope it will help :)
