— 3х – 6+(-1)
do anybody know this answer

Answers

Answer 1

Step-by-step explanation:

its -3x-6+(-1)? if yes please let me know. thanks

Answer 2

Answer:

x = -10

Step-by-step explanation:

First combine like terms; -6 + -1 = -7, since + a negative is just minus.  

(So -6 - 1.)  Rewrite the equation as -3x - 7.  Divide x from both sides, so

-3 - 7 = x.  Simplify into x = -10.  

I'm so sorry if I'm wrong, I hope this helps though!

Why does paying off the highest interest rate credit card first make the most mathematical sense?

Answers

Because you’re paying interest first so the faster you pay off the interest the faster you get to the principal and pay the actual debt off

Answer:

Paying off the highest interest rate credit card first makes the most mathematical sense because it will save you more money and allow you to redirect funds to other financial goals faster. Paying off the highest interest rate first is better because this way you get to avoid financial problems and avoid having to pay too much money of interest since the card with the highest interest rate is usually the one that will cause you the most financial pain.

When graphed, will the line x - 2y = 6 be
parallel, perpendicular or neither to a line that
passes through the points (5,2) and (3,6)?

Answers

Answer:

Step-by-step explanation:

Slope of x-2y=6 is ½.

Slope of line through (5,2) and (3,6) = (6-2)/(3-5) = -2

The two slopes are negative reciprocals of each other (i.e., their product is -1), so the two lines are perpendicular.

1 bracelet costs $7

5 bracelets is 7*5=35

As we can see with the numbers they gave us every bracelet costs 7 dollars, 1 =7, 2=14 and so on. With this information we can just take the number 5 and multiply it by 7 which would equal 35. Or you could add 7 to 21 and then 7 to 28. Whichever one works for you.

Pentagon ABCDE is similar to pentagon RSTUV . The perimeter of pentagon ABCDE is 36.8 centimeters.


What is the length of ST ?

19.8 cm
18 cm
25.8 cm
15 cm

Answers

Answer:

ST = 15 cm

Step-by-step explanation:

find BC first by adding four other sides and subtracting from 36.8

sum of 4 sides is 30.8, so BC = 6

Now find ST by creating a proportion from corresponding sides:

BC / ST = DE / UV

6 / ST = 13.2 / 33

Cross-multiply:

13.2ST = 198

ST = 198/13.2

ST = 15
