|3x| = 9 Variable please.

Mathematics
1 answer:
Lorico [155]2 years ago
7 0

Answer:

x = 3 or x = -3

Step-by-step explanation:

The absolute value of 3x = 9

Divide nine by 3 to get 3

Absolute value represents the number of spaces an integer is from 0, so the answer could also be -3, as the absolute value of 3 x -3   (-9) is 9.

Answer:

10.5 cm^2

Step-by-step explanation:

Area of a triangle = 1/2(L x H)

height = 3 cm

therefore

Area of the triangle = 1/2( 7×3)

Area = 10.5 cm^2

Write a function rule that represents each sentence.1. y is 5 less than the product of 4 and x. 2. 2.5 more than the quotient of
Mrac [35]
1. It is important to go through each of the words given in the question to get through to the actual answer. The function will be:
y= (4 * x) - 5
  = 4x - 5

2. The function of this statement will be
(h/3) + 2.5 = w

1. Let us assume the price of a pizza = p
    From the first part we can write 
    p = $6.95
    On adding the price of each topping "t" we get
    p = $6.95 + ($0.95) * t
       = <span>$6.95 + $0.95t</span>
    I hope it helps you.

(255)/(6)*(672)/(9)+(37)/(9) <br> How do you work this out step by step??
koban [17]
Step 1. Type it into a Google search box or calculator. (You need to use a calculator anyway.) The result is 3177 4/9.

If you're doing this according to the Order of Operations, you do the multiplication and division left to right. This means the first calculation you do is
  255/6 = 42.5
Next, you multiply by 672
  42.5*672 = 28560
Then divide by 9
  28560/9 = 3173 3/9

You continue by doing the division
  37/9 = 4 1/9

And finish by adding the two results
  3173 3/9 + 4 1/9 = 3174 4/9

_____
If you're doing this by hand, you can recognize the first term as the product of two fractions, so is the product of numerators divided by the product of denominators.
  (255*672)/(6*9)
Using your knowledge of divisibility rules, you can do the division 672/6 to simplify this to
  (255*112)/9
Now, the first term and the second term have the same denominator, so you can add the numerators before you do the division.
  (255*112 + 37)/9 = (28560 + 37)/9 = 28597/9
You end up having to do only two simple divisions, rather than 3 of them.
  28597/9 = 3177 4/9
