Answer:
Step-by-step explanation:
-2(x-4) =10x+2
-2x--8= 10x+2
-2x+8= 10x+2
-2x+10x= 8+2
8x= 10
x= 0.8
Answer:
Step-by-step explanation:
To solve for x you first isolate the variable you want on one side. We will do this by using PEMDAS and expanding our terms fully first before we move our terms around.
[tex]-2(x-4)=10x+2\\-2x-8=10x+2[/tex]
We then isolate our term, remember to add numbers and variables to both sides so you aren't changing the value of the equation, and solve for x.[tex]-2x-8=10x+2\\-2x-8-2+2x=10x+2-2+2x\\-10=12x\\\frac{-10}{12}=x\\\frac{-6}{5}=x\\-1.2=x\\[/tex]

I NEED SOMEONE WHO IS GOOD AT MATH AND WHO CAN GIVE ME THE RIGHT ANSWERS FOR THESE ASAP NO LINKS !!!
Step-by-step explanation:
2x + 9 = 35
→ 2x = 35 - 9 = 26
→ x = 26/2 = 13
→ x = 13
therefore, option A is correct
4 + | 7 - m | = 5
→ | -m + 7 | = 5 - 4
→ - m + 7 = 1 ( however or (only) m < 7 )
→ ( -m + 7 ) ( however or only m ≥ 7 )
→ m = 6 and m = 8
therefore, Option B is correct.
3t + 3/5 = 6
→ 3t + 3 = 6 × 5 = 30
→ 3t = 30 - 3 = 27
→ t = 27/3 = 9
→ t = 9
6(d + 1) - 2d = 54
→ 6d + 6 - 2d = 54
→ 4d + 6 = 54
→ 4d = 54 - 6 = 48
→ d = 48/4 = 12
→ d = 12
-110 = 13 + 3(4h - 6)
→ -110 = 13 + 12h - 18
→ -12h = 13 - 18 + 110
→ -12h = 105
→ h = 105/12
→ h = 8.75

What is the rate of return when 35 shares of Stock A, purchased for $20/share, are sold for $815? The commission on the sale is $6. Rate of Return = [?] % Give your answer as a percent rounded to the nearest tenth
Cost price:-
[tex]\\ \sf\longmapsto 35\times 20[/tex]
[tex]\\ \sf\longmapsto 700[/tex]
Commision=$6Total sold price=815+6=823$Now
Return=823-700=123
Rate of return
[tex]\\ \sf\longmapsto \dfrac{123}{700}\times 100[/tex]
[tex]\\ \sf\longmapsto \dfrac{123}{7}[/tex]
[tex]\\ \sf\longmapsto 17.5\%[/tex]
The rate of return on the stock will be equal to 17.3%.
What is the Percentage?The Latin phrase "per centum," which means "by the hundred," is where the English word "percentage" comes from. Percentage segments are those with a numerator of 100. In other words, it is a connection where the whole is always deemed to be valued 100.
As per the given information in the question,
Total number of stocks = 35
Purchase price of each stock = $20
Then, the price of 35 stocks will be,
35 × $20 = $700
The selling price of all stocks = $815
Also, the commission for selling is $6.
So, the extra money earned will be,
815 - 700 + 6 = 115 + 6
= $121
So, the rate of return from the original price will be,
= 121/700 × 100
= 12100/700
= 17.3%

Answer:
Step-by-step explanation:
During a cold winter, the temperature stayed below zero for ten days (ranging from -20 to -5). The variance of the temperatures of the ten day period A. is negative since all the numbers are negative B. must be at least zero C. can not be computed since all the numbers are negative D. can be either negative or positive
Using the variance concept, it is found that the correct option is:
B. must be at least zero
The mean of a data-set is the sum of all observations divided by the number of observations.The variance of a data-set is the sum of the differences squared between each term and the mean, divided by the number of values.Since the variance is squared, it's minimum value is 0, and thus, the correct option is:
B. must be at least zero
