Use the distributive property to write an equivalent expression.
8(3v+3w-2)
Answer:
8(3v+3w-2)=(8×3v+8×3w-8×2)
Step-by-step explanation:
8×3v=24v.
8×3w=24w. [24v+24w-16]=(8×3v+8×3w-2×8)
8×(-2)=-16.

y =
Answer:
[tex]y = - 5[/tex]
Step-by-step explanation:
[tex] - 5(y - 3) - 10 = - 6y[/tex]

Answer:
[tex]{ \underline{ \sf{it \: is \: {10}^{9} }}}[/tex]
Step-by-step explanation:
[tex](10 {}^{4} ). \frac{ {10}^{12} }{ {10}^{7} } = ( {10}^{4} ). {10}^{(12 - 7)} \\ \\ = ( {10}^{4} ). {10}^{5} \\ = {10}^{(4 + 5)} \\ = {10}^{9} [/tex]
Answer:
[tex]10^{9}[/tex]
Step-by-step explanation:
I. [tex]10^{4} * 10^{12-7}[/tex]
= [tex]10^{4} * 10^{5}[/tex]
= [tex]10^{4 + 5}[/tex]

A trader sold 250 articles for $525,000.00 at a profit of 25%.
a.Calculate the cost of each article.
b.If the trader had wanted 45% profit on the cost price then how much would he sell the articles?
Answer:
a. $2100 b. $945000
Step-by-step explanation:
You have to divide 525000 and 250 to solve for "a". To solve for "b" you need to find %100 of the profit and do %100 of the profit times 0.45 to see how much is %45 of profit.
What is 10% of a number whose square
is 81
Answer: 0.9
Step-by-step explanation:
Let x be the number
Determine the value of the number
x² = 81
√x² = √81
x = 9
Find the 10% of the number
Final number = rate of percentage × original number
Final number = 10% × 9
Final number = [tex]\boxed{0.9}[/tex]

use the following list to find the average or mean, the median, the mode, and the range 10, 15, 5, 8, 6, 6, 2
Answer:
Mean - 7.43
Median - 6
Mode - 8
Range - 13
Step-by-step explanation:
To find the mean/average, add up all the numbers and divide the sum by the # of data points. (ex. you have 7 numbers, so you divide the sum of the numbers by 7.)
The median of a set of data is the middle number of ascending numbers in the data. If there was an even number of data points you would have to add the 2 middle numbers and divide by 2.
The mode is the number that appears most frequently in the data set.
To find the range, just subtract the lowest number in the data set from the greatest number.
Answer:
mean= 7.4, median = 6, mode =6, range = 13
Step-by-step explanation:
mean = 10 + 15 + 5 + 8 + 6 + 6 + 2 ÷ 7
= 52 ÷ 7
= 7.4
median= 2, 5, 6, 6, 8, 10 , 15
6
median is the middle number from ascending order
mode = 6
mode is the number that occurs the most
range = 15 - 2
13
range is the different between the largest and smallest number
