Given the following expression.

2 1/4 - (-3 2/5)
A. Rewrite the expression using addition.

B. Evaluate the expression.

Answers

Answer 1
In order to rewrite the expression using addition, you would change all the subtraction signs and make the second terms negative. This means that your new expression is 2 + -2 1/4 + 3 2/5. If the number is already negative, the second negative sign would make it positive. Once you've got Part A done, do 2 + -2 1/4 which would give you -1/4. Then you add -1/4 and 3 2/5 by finding common denominators, 20. -5/20 + 3 8/20 would give you 3 3/20 as your final evaluated answer.
Answer 2
Answer:1/4-(-3 2/5)1/4--3 2/51/4+3 2/50.25+3 0.43.25,0.4.

Sari applied the distributive property using the greatest common factor to determine the expression that is equivalent to 84 +40. Her work is shown below.

Factors of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40

84 + 40 = 2 (42 + 20)

What statement best describes Sari’s error?

a.14.6. b.when u multiply both part of ratio by the same number you make ur ratio....so we we're dealing with a ratio,if we r multiplying or(dividing)both part of it's by the same number we are creating equal ratio

Answer:

EXAMPLE: 2,3 = 4,6 = 6,9

Step-by-step explanation:

THESE ARE ALL EQUIVALENT BECAUSE... you are just multiplying each number by the same factor. 2x2=4 and 3x2=6 this gives me the next ratio of 4,6. But only multiply the first given ratio to find the next.

Which expression would be easier to simplify if you used associative property to change the grouping.

(I'll give brainliest for the correct and most accurate answer.)

Answers

Answer:

D. (2 + 3/7) + 4/7

Step-by-step explanation:

In B and C, the numbers involved in expressions are integers.

Hence, they can be easily added or subtracted.

In D, the numbers involved in expression are fractions which are not grouped together.

They can be added but by using associative property, it becomes much more easier.

That is, grouping fractions.

The company president has said he needs up-to-date financial statements to share with the bank on January 21 at a dinner meeting that has been called to discuss Picton's obtaining loan financing for a special building project. Tamira knows that she will not be able to gather all the needed information in the next 24 hours to prepare the entire set of adjusting entries. Those entries must be posted before the financial statements accurately portray the company's performance and financial position for the fiscal period ended December 31, 2016. Tamira ultimately decides to estimate several expense accruals at the last minute.
