Which of the following shows the correct process of solving −30+4.5?(1 point)
Responses

−30+4.5=−3+4.5=1.5
negative 3 superscript 0 baseline plus 4.5 equals negative 3 plus 4.5 equals 1.5

−30+4.5=(−3)0+4.5=1+4.5=5.5
negative 3 superscript 0 baseline plus 4.5 equals left parenthesis negative 3 right parenthesis superscript 0 baseline plus 4.5 equals 1 plus 4.5 equals 5.5

−30+4.5=−3⋅0+4.5=0+4.5=4.5
negative 3 superscript 0 baseline plus 4.5 equals negative 3 times 0 plus 4.5 equals 0 plus 4.5 equals 4.5

−30+4.5=−1⋅30+4.5=−1⋅1+4.5=−1+4.5=3.5
negative 3 superscript 0 baseline plus 4.5 equals negative 1 times 3 superscript 0 baseline plus 4.5 equals negative 1 dot 1 plus 4.5 equals negative 1 plus 4.5 equals 3.5

Answer 1

The correct process of solving −30+4.5 is:

−30+4.5=−3+4.5=1.5

Answer 2

−30+4.5=−3+4.5=1.5
ah,no way
−30+4.5= -25.5
perhaps you mean
−3.0+4.5=−3+4.5=1.5

Answer 3

Apologies for the mistake in my previous response. You are correct, the correct process should be:
−30+4.5= -25.5
Alternatively, if you meant -3.0 instead of -30, then the correct process would be:
−3.0+4.5=−3+4.5=1.5.

Answer 4

or if you mean
-3^0 +4.5
then
1 + 4.5 = 5.5
or if you mean
-3^0 + 4^.5
then
1 + 2 = 3

Answer 5

Apologies for any confusion. The question did not specify the use of exponents or square roots. If the expression is interpreted as -3^0 + 4.5, then the correct process would be:

-3^0 + 4.5 = 1 + 4.5 = 5.5

Alternatively, if the expression is interpreted as -3^0 + 4^.5, then the correct process would be:

-3^0 + 4^.5 = 1 + 2 = 3

Thank you for providing the clarification.

Answer 6

The question title included "zero power rule of exponents".

Answer 7

Apologies for overlooking that detail. If the question is specifically asking about the zero power rule of exponents, then the correct process would be:

-3^0 + 4.5 = -1 + 4.5 = 3.5

Thank you for pointing that out.

Answer 8

Solve for x .
−12+x=48 (1 point)
Responses

x=−60
x equals negative 60

x=60
x equals 60

x=36
x equals 36

x=−36
