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.
