Myra is evaluating the expression –31.7 + 4.5x, when x = 2.1.     –31.7 + 4.5(2.1)     –27.2(2.1)     –57.12 what was myra’s error? myra should have multiplied -31.7 and 2.1 first. myra should have multiplied 4.5 and 2.1 first. myra should have subtracted -27.2 and 2.1 first. myra should have added -31.7 and 2.1 first.

–31.7 + 4.5x, when x = 2.1.

-31.7 + 4.5(2.1)

-31.7 + 9.45

Myra should have multiplied 4.5 and 2.1 first.

B.Myra should have multiplied 4.5 and 2.1 first.

Step-by-step explanation:

We are given that Myra is evaluating the expression

-31.7+4.5 x when x=21.

We have to find the error in Myra's calculation

When x=2.1

-31.7+4.5(2.1)

-31.7+9.45

=-22.25

By using DMAS rule

D=Divide

M=Multiply

A=Addition

S=Subtraction

But Myra first add  -3.7 to 4.5 then multiply

Hence, Myra should have multiplied 4.5 and 2.1 first instead of add.

B.Myra should have multiplied 4.5 and 2.1 first.

the option best identifies the textual evidence that supports this conclusion is c.) when an argument is over, how many weighty reasons does a man recollect which his heat and violence made him utterly forget? in order to recognize textual evidence is to identify the topic sentence where the author states the main idea. textual evidence is what supports the topic sentence or main idea of a passage.
