Answer:

My answer is (-3, 17).

Step-by-step explanation:

You will use minus sign for the equation in other to eliminate one of the letters and use the other one to find the one eliminated later...Which means that 4x+y=5 (-) 3x+y=8..... the minus sign will eliminate +y and +y in each equation because the "+y" in the second equation will be turned to -y because + times(×) - will give us minus sign so the "y" will be eliminated to give space for the 'x" .After the x has been found which is x=-3 then you will substitute x=-3 into the any equation and then you will also find the "y" which is y=17.....Thank you

A store is hoping an advertising campaign will increase their number of customers by 30%. They currently have about 80 customers

leonid [27]

Answer:

There will be 104 customers a day, after advertising campaign

Step-by-step explanation:

Current number of customers in a day in shop = 80

After advertising campaign, the customers will increase = 30%

So, new customers will be:

We can find new customers by adding new 30% customers to the current 80 customers.

First find 30% of 80

$30\% \ of \ 30\\=\frac{30}{100}*80\\=24$

Now, add 24 to current 80 customers.

Number of customers = 80+24 = 104

So, there will be 104 customers a day, after advertising campaign

Which expression represents the prime factorization of 96?

SCORPION-xisa [38]

It is not A. because 8 is not a prime number.

It is not B. because 12 is not a prime number.

C. 2 x 2 x 2 x 2 x 2 x 3 = 4*4*6= 96

D. 2 x 2 x 2 x 2 x 2 x 3 x 3= 4*4*6*3=16*18= 288

Answer is C. -2 x 2 x 2 x 2 x 2 x 3 : 96 ( not D. = 298 , 298 is greater than 96)
