Which options could be the next step in simplifying this expression?27 + (3 + 41)

Choose exactly two answers that are correct.

A.

27 + 44 (use order of operations)

B.

30 + 68 (use the distributive property)

C.

30 + 41 (use the associative property)

D.

68 + 30 (use the commutative property

Answers

Answer 1

Answer: The correct answer is A and C. In PEMDAS, parenthesis are the first things that need to be simplified. And the associative property states a (b + c) = (a + b) + c. And you can also add up the numbers in the answer choice to make sure :)

Answer 2

Answer: $Associative\ property:a+(b+c)=(a+b)+c\n\n27+(3+41)=(27+3)+41=30+41=71\leftarrow\boxed{C}$

The earnings, E of a DJ who charges fee of $250 and an additional $40 per hour,h. NEED HELP ASAP

Answers

Given that you say the question doesn't state the duration of work, I suspect it is asking for an equation to describe E in any situation.

Therefore, let's take x to be the number of hours he is working for.

We know he earns a base $250, so E is going to be 250+something.

That something we know is a multiple of the number of hours he is working for. If it is $40 per hour, it is going to be 40x as if x is 1 that gives 40, if it is 2 it gives 80 and so on.

If we substitute this all in we get:

E = 250 + 40x
Where x is the number of hours he works for.

What percent of 145 is 29

Answers

$(x)/(100)* 145 = 29\n\nx = 29* (100)/(145)\n\n\boxed{x = 20}$

The percentage value of 29 from 145 is 20%

Given the parameters which could be used in our calculation:

Numerator = 29
Denominator= 145

Write the expression thus :

(29/145) * 100%

0.2 * 100%

= 20%

Hence, the percentage Value of 29 from 145 is 20%

The average rate of the first part of Yi’s walk on a park loop was 4 miles per hour. She then met up with a friend and the two walked the rest of the way at an average rate of 5 miles per hour. The entire 3-mile walk took Yi 42 minutes (0.7 hour). Which equation can be used to solve for x, the time in hours that Yi spent walking before meeting her friend?

Answers

so she walked during this time with 4 miles per hour (x*4)

during the rest of the way (which is 0.7-x, as the whole way took her 42 minutes, so the rest is 0.7-x) she walked with 5 miles per hour - the distance was (0..7-x)*5 m/h

the total distance was 3 miles, so if we sum the two distances, we will get 3 miles:

x*4+ (0.7-x)*5=3

let's remove the bracket:

4x+0.7*5-5x=3

4x+3.5-5x=3

subtract 3.5 from both sides:
4x-5x=3-3.5
-x=-0.5

multiply both sides by (-1)
x=0.5:

so she walked for half an hour alone, that is for 30 minutes!

Answer:

D, 4x + 5(0.7 – x) = 3.
