Use the distributive property to evaluate each expression <br> 4(8-7), 4(x-6y), 6(5-q), (d+2)(-7)
Whitepunk [10]

Answer:

Rewrite the expression 10(15 – 6) using the distributive property of subtraction.

A) 10(6) – 10(15)

B) 10(9)

C) 10(6 –15)

D) 10(15) – 10(6)

Show/Hide Answer

A) 10(6) – 10(15)

Incorrect. Here a greater number would be subtracted from a lesser number, and the answer would not be a whole number. The correct answer is 10(15) – 10(6).

B) 10(9)

Incorrect. The numbers in parentheses were subtracted before the number 10 could be distributed. The correct answer is 10(15) – 10(6).

C) 10(6 –15)

Incorrect. You probably used the commutative law instead of the distributive property. The correct answer is 10(15) – 10(6).

D) 10(15) – 10(6)

Correct. The 10 is correctly distributed so that it is used to multiply the 15 and the 6 separately.

Suppose<br> cos(π/2−x) =3/5, cos x =4/5<br> find sin, tan, csc, sec, cot
Pani-rosa [81]
Cos (π/2 - x) = sin x = 3/5
tan x = sin x / cos x = 3/5 / 4/5 = 3/4
csc x = 1/sin x = 1 / 3/5 = 5/3
sec x = 1/cos x = 1 / 4/5 = 5/4
cot x = 1/tan x = 1 / 3/4 = 4/3.

Last month, the daily balance in Joana's credit card account was $1,000 for 9 days, $750 for 10 days, $850 for 4 days, and $900
FrozenT [24]

Answer:

<em />Average = \$873<em />

<em />

Step-by-step explanation:

Given

$1000 for 9 days

$750 for 10 days

$850 for 4 days

$900 for other days

Required

Compute the daily average

First, we need to compute the number of days her balance is $900

Assuming the billing cycle is 30 days;

Number\ of\ days = 30 - (9 + 10 + 4)

Number\ of\ days = 30 - 23

Number\ of\ days = 7

The Average is then calculates using:

Average = \frac{\sum fx}{x}

Average = \frac{1000 * 9 + 750 * 10 + 850 * 4 + 900 * 7}{9 + 10 + 4+ 7}

Average = \frac{26200}{30}

Average = 873.333333333

<em />Average = \$873<em> --- Approximated</em>
