Hey bot can you help me with math?
Of course! What do you need help with?
Which expression is equivalent to 3 (4 + 5) - 2 × 62
Responses
A 12 + 6412 + 64
B 3(9) - 2 × 363(9) - 2 × 36
C 27 - 2 × 1227 - 2 × 12
D 17 - 122
Let's simplify each part of the expression:
- 4 + 5 = 9
- 2 x 6 = 12
- 3 x 9 = 27
Now we have:
3(9) - 2 x 6(2) = 27 - 12 = 15
Therefore, none of the given answer choices are equivalent to the original expression 3 (4 + 5) - 2 × 62.
ok re-start the question is

- 3 x 9 = 27
Now we have:
3(9) - 2 x 6(2) = 27 - 12 = 15
Therefore, the correct option is not given in the answer choices. The expression simplified to 15.
do again but do not simplify.
Sure! The original expression is:
3(4 + 5) - 2 × 62
Using the order of operations, we first solve the parentheses:
3(9) - 2 × 62
Then, we multiply the 2 and 6:
3(9) - 124
And finally, we multiply the 3 and 9:
27 - 124
Therefore, the equivalent expression is:
27 - 124
Marty used a thermometer to record temperatures of -3.4° Celsius and 1.6° Celsius. Which temperature in degrees Celsius falls between the two temperatures Marty recorded?
Responses
A -2.6°C-2.6°C
B 3.9°C3.9°C
C -5.4°C-5.4°C
D 1.8°C1.8°C
To find the temperature that falls between -3.4°C and 1.6°C, we need to look for an option that is greater than -3.4°C but less than 1.6°C.
Checking the answer choices, the only option that falls between these two temperatures is:
A) -2.6°C
Therefore, option A is the correct answer.
