Answer:
-5 + 3(7.2 - 3.2) equals 7.
Step-by-step explanation:
The order of operations states the order in which different mathematical operations should be done first, you can use the mnemonic PEMDAS to remember the order to complete each operation. PEMDAS states that the order must be followed as Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction. In the expression -5 + 3(7.2 - 3.2), the three mathematical operations being used are subtraction, multiplication, and parenthesis, so based on PEMDAS, the order to complete them is parenthesis, multiplication, and subtraction. -5 + 3(7.2 - 3.2) = -5 + 3(4) = -5 + 12 = 7, so that is your final answer.
2) Inserting zeros at the right end of a decimal does not change its value
0.3 = 0.3000
4) To estimate the difference between 0.31 and 0.108, subtract 0.3.
22) 75.285 + 2 + 3.871 + 0.5 = 81.656
42) 0.01 - 0.0001 = 0.0099
50) 9 - 4.63 = 4.37
Answer:
Reference Point
Step-by-step explanation:
The answer is reference point. This is because reference point is used to determine if an object is in motion or if it has changed is direction.
Thus, reference point has to be a value of zero for us to use it to determine if an object has moved.
So she has used two kinds of sugar, brown and powdered.
She used
cups of brown sugar and
cups of powdered sugar: we need to add the two numbers:
+
= 2+1+
=3
so the correct answer is 4.5
