Evaluate the expression below using the properties of operations. Show your steps to receive full credit. −36 ÷ 14 ⋅ (−18) ⋅ (−3) ÷ 6

Answers

Answer:

(-162)/7 or -23 1/7 as a mixed fraction

Step-by-step explanation:

Simplify the following:

(-36)/14 (-18) (-3)/6

Hint: | Express (-36)/14 (-18) (-3)/6 as a single fraction.

(-36)/14 (-18) (-3)/6 = (-36 (-18) (-3))/(14×6):

(-36 (-18) (-3))/(14×6)

Hint: | In (-36 (-18) (-3))/(14×6), divide -18 in the numerator by 6 in the denominator.

(-18)/6 = (6 (-3))/6 = -3:

(-36-3 (-3))/14

Hint: | In (-36 (-3) (-3))/14, the numbers -36 in the numerator and 14 in the denominator have gcd greater than one.

The gcd of -36 and 14 is 2, so (-36 (-3) (-3))/14 = ((2 (-18)) (-3) (-3))/(2×7) = 2/2×(-18 (-3) (-3))/7 = (-18 (-3) (-3))/7:

(-18 (-3) (-3))/7

Hint: | Multiply -18 and -3 together.

-18 (-3) = 54:

(54 (-3))/7

Hint: | Multiply 54 and -3 together.

54 (-3) = -162:

Answer: (-162)/7

An online music store is offering a promotion. When you spend $45 or more, you receive 3 songs for free. You buy an album for $15. Identify the inequality that represents how much more money m you must spend to receive the three free songs.

Answers

Answer: x ≥ $30.

Where x is the amount of money that you need to spend if you want to have the 3 free songs.

Step-by-step explanation:

When you spend $45 or more, you get 3 free songs.

You already bought an album that costs $15, then the minimum amount that you need to spend is (when you spend exactly $45):

$45 - $15 = x = $30.

Then the inequality is:

x ≥ $30.

Because if you spend more than $45 you also get the songs.

$6.56

Step-by-step explanation:

First, take 8 and divide it by 100. Then you have 0.08. multiply that by 9. You get 0.72, that is how much the price increases every year. multiply that by 2, and you get 1.44. subtract 1.44 from 8, and you are left with $6.56, the price it was two years ago.

Raju’s father’s age is 5 years more than three times Raju’s age. Find Raju’s age,

if his father is 44 years old. ( 13 years)
please help

Answers

Answer:

Step-by-step explanation:

In order to find the answer, let's work backwards to find the original. We have to do the opposite to get to the Raju's age. We will start with his fathers age. (44) Then we will subtract five from it so that it will be divisible by three.

44 - 5 = 39

Then we just have to divide by 3.

44/3 = 13

His age is 13 years old.

.Rahul and his wife work in Mohan's farm. The Government has declared that the farm workers should be paid Rs. 71 for a day's work. But the land lord, Mohan pays Rs. 60 for Rahul and Rs.55 to his wife. If Rahul works for 55 days and his wife for 40 days, what amount of money will they earn together?

Answers

Answer:

Rs. 5500

Step-by-step explanation:

The government has declared that farm workers should be paid Rs. 71 for a day's work

The landlord Mohan pays Rahul Rs. 60 and pays Rs. 55 to his wife

Rahul works for 55 days

= 60 × 55

= Rs. 3,300

His wife works for 40 days

= 55 ×40

= Rs. 2,200

Therefore the total amount of money earned together can be calculated as follows

= 3300 + 2200

= Rs. 5500

Hence they will earn Rs. 5500 together

Brianna ran 6 laps around a circular track with the diameter of 120 feet how far did she run

Answers

Answer:

2261.94671

Step-by-step explanation:

You must first find the circumference of the track. Using 2(pi)r.

Where pi=3.14... and r=radius

you can find the radius by dividing the diameter by 2, 120/2=60

Afterwards you input 60 into the equation. 60*(pi)*2= 376.99111843077515

Using that number you multiply it by 6 because she ran the circumference 6 times. 6*376.99111843077515 = 2261.94671

NOTE: The question may require you to simplify at certain times so answers may vary slightly. EX: pi = 3.14, Circumference = 377

Answers

Answer:

x. a.

y. b

z. c.

Step-by-step explanation:

So from the middle column, we know that each row or colum must be -12 because 1 - 8 - 5. x + 1 - 12 should be = - 12, so x -11 = 12, so x = -1

For z, - 12 + 3 + z = -12, so z = -3

For y, y - 5 + z = -12, but we know z so we can plug in -3:

y - 5 - 3 = - 12

y - 8 = -12

so y must be -4

Answer. A
Explanation. slope intercept form is y= mx + b. m represents the slope and b represents the y intercept (the point where the line meets the y-axis). We know that the slope is 1/3 but since the y-point is 0, there is no VISIBLE “b” in the equation. The correct solution is A :)
