Answer:

Below

Step-by-step explanation:

Given Data:

  • The sum of two numbers is less than 2
  • If we subtract the second number from the first , the difference is greater than 1

Q) What are the two numbers?

Lets suppose the first number to be x and the second number to be y

The first point states sum of two number which is x + y is less than 2 so our first expression becomes,

x+y

The second point states that the if we subtract the second number from the first number which states x - y the difference is greater than 1 so our second expression becomes,

x-y

1) The riddle can be represented by a system of inequalities. Write an inequality for each statement.

The inequality for the first statement is

x+y

The inequality for the second statement is

x-y>1\\

I assume the second part to the question would be solve for x and y xD

so here goes

2)

If we just simply add both the equations we get the following result:

x+x+y-y=2+1

Just suppose there is an equal to sign instead of less than or greater than

x+x+y-y=2+1\\2x+0=3\\x=3/2\\x=1.5\\

now put the value of x in any one of the two equations I choose equation 1

x+y=2\\1.5+y=2\\y=2-1.5\\y=0.5

I attached an image so you can understand it better :)

Robby has 9 coins that total $2.15. if he only has nickels and dimes, write the system of equations.
Illusion [34]

Let's assume

number of nickels =n

number of dimes =d

we are given

total number of coins =9

so, we get

n+d=9

we know that

1 nickel =$ 0.05

and

1 dimes =$0.10

so, total amount is

=0.05\times n +0.10\times d

we are given

total amount =$2.15

so, we get

0.05n +0.10d=2.15

so, we get system of equations as

n+d=9

0.05n +0.10d=2.15................Answer

-8z+12=-12<br><br><br> plz help asap<br> what is the answer<br> and what does z stand for??!?
Fofino [41]

Answer:

The answer is that z = 3

Step-by-step explanation:

Once you solve you get z = 3

-8z + 12 = -12         you subtract -12 from both sides to get rid of the positive 12

     -12 = -12

__________

-8z = -24

__     __              divide -8 both sides

-8      -8             two negatives equal a positive

z = 3
