Hello from MrBillDoesMath!

Answer:

11/ 1009 (.0109 approximately)

Discussion:

99/9081 = => as 9081 = 9 * 1009 = 3 * 3 * 1009

99/ ( 3 * 3 * 1009) =

(99/(3*3)) * (1/1009) =

(99/9) * (1/1009) =

11/ 1009 =

.0109 approximately

Thank you,

MrB

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?

netineya [11]

Answer:

Myra's Error: Addition instead of multiplication

Correct answer: -22.25

Step-by-step explanation:

Myra is evaluating the expression.

Expression: -31.7 + 4.5x for x=2.1

Step 1: Put x=2.1 into expression

Myra's Steps Correct Step

-31.7 + 4.5(2.1) -31.7 + 4.5(2.1)

Thus, first step correct.

Step 2: Simplify 4.5(2.1) by multiply

Myra's Steps Correct Step

-27.2(2.1) -31.7 + 9.45

Thus, second step incorrect.

Therefore, Myra's error in second step. She did addition(-31.7+4.5) instead of multiplication(4.5×2.1)

Step 3: Combine like terms

-31.7 + 9.45 = -22.25

Hence, The correct answer of the given expression is -22.25

32.323232 as a fraction in simplest form

Step2247 [10]

Let x = 32.323232…

Then 100x = 3232.323232…

It follows that

100x - x = 3232.323232… - 32.323232…

99x = 3200

x = 3200/99
