Please answer!!! 3x+4=9x+3

Mathematics
1 answer:
kow [346]4 years ago
5 0

Answer:

x = 1/6

Step-by-step explanation:

"solve for x" would be better and clearer than "please answer."

We start the solution by subtracing 3x from both sides, obtaining

4 = 6x + 3

and then isolate the 3x term by subtracting 3 rom both sides:

6x = 1

Finally we divide both sides of this result by 6, obtaining

x = 1/6     This is the "answer" to the problem "solve 3x + 4 = 9x + 3 for x."

without actually performing the long division state whether 17 / 3125 will have a terminating decimal expansion or a non-termina
baherus [9]

Answer:

It is terminating decimal expansion.

Step-by-step explanation:

17/3125 is a terminating decimal expansion.

REASON:

If the factors of the denominator are in the form of 2^n 5^m then the rational number is a terminating decimal expansion otherwise it is recurring. Here n and m are non negative integers.

Proof:

Lets have a look on the solution of the given term.

17/1325

We will break the denominator in the factors:

If we multiply 5 five times than it will give us 1325.

17/1325 = 17/5^5 * 2^0 = 17/2^0 * 5^5

We know that any number with exponent zero = 1

∴ 2^0 = 1

So it satisfies our explanation that the factors of the denominator are in the form of 2^n * 5^m and n and m are non negative integers.

Thus this term has a terminating decimal expansion....

Help me pleseeeeeee asappppp
pentagon [3]

Answer:

(-2.5, -10)

Step-by-step explanation:

Midpoint Formula: (\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )

Step 1: Plug in

x = (-2 + -3)/2

y = (-8 + -12)/2

Step 2: Evaluate

x = -5/2

y = -20/2 = -10

Step 3: Format into coordinates

(-5/2, -10)

Step 4: Convert to decimal

(-2.5, -10)
