Solve for x. 3(15 - x) = 2x

Mathematics
1 answer:
Morgarella [4.7K]3 years ago
8 0

Answer:

well

Step-by-step explanation:

3 times 15 is 45

then 3 times negative x is -3x

so 45 - 3x = 2x

3 x moved to the other side turns positive

so you have

5x = 45

45÷5

x = 9

How to write in inqvality
Kitty [74]

Answer:

If you mean "How do I write an inequality?", the answer is COEFFICIENTxVARIABLE {any symbol} COEFFICIENTxVARIABLE >/< INTEGER

In other words, you should have something like this: -3x + 4v < 63

Or this: 51x - 16v > 11

Or anything along those lines.

Malika bought 7 new pairs of shoes. Each pair of shoes cost the same amount and was discounted by $21.75.
ikadub [295]

Multiply the amount of the discount by pairs of shoes:

21.75 x 7 = 152.25

Add that to the total she spent:

152.25 + 654.50 = 806.75

Divide the total by pairs of shoes:

806.75/7 = $115.25

The answer is C. $115.25

Show all work <br> Find exact value of x
Illusion [34]

Answer:

129 is x

Step-by-step explanation:

Your equation would be like this x= 45 + 6=180 (180 because the sum of the angle measures in a triangle is 180 always)

so once you add 45+6 =51 the equation is now x=51=180 so you subtract 51 from both sides so it equals as this x=51=180

                                                                                         x =-51= -51

                                                                                         x=         129

Write an equation in point slope form of the line that passes through the point (6,-5) and has the slope 1/2
babymother [125]

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

where

m is the slope

( x1 , y1) is the point

From the question we have the final answer as

\huge y + 5 =  \frac{1}{2} (x - 6) \\

Hope this helps you
