3 0

Answer:

489 or -113

Step-by-step explanation:

Whats 30 times 30 plus 45 minus 456

rewrite in terms of numbers:

30 * 30 + 45 - 456

remember the order of operations and solve:

30 * 30 + 45 - 456

=900 + 45 -456

= 945 - 456

= 489

the answer could change depending on the placement of parenthesis, such as if the equation was:

30 * (30 + 45 -456)

solve with the order of operations:

30 * ( 30 + 45 - 456)

= 30 * (75 - 456)

= 30 *(-381)

= -11430

Midpoint formula: (x₁ + x₂/2 , y₁ + y₂/2)

Substitute the values into the formula.

(-5 + 3/2 , 3 - 1/2)

(-2/2 , 2/2)

(-1,1)

Therefore, the midpoint is (-1, 1).

noname [10]
<h2>Key Ideas</h2>
  • Systems of equations

<h2>Solving the Question</h2>

When both sides of the equal sign are equal, there are infinite solutions.

When you are able to isolate the variable, there is only one solution.

When the equation states an untrue expression, there is no solution.

1=3 is an untrue fact. Therefore, there would be no solutions to the system.

<h2>Answer</h2>

There is no solution
