Answer:

X= -10

Step-by-step explanation:

15=3x-15

Minus the numbers on the other side of the variable

15=3x-15

-15 -15

=0 -30

In algebra the - before a number gets counted as a negative so -15 minus 15 = -30

Then since we still have 3x we divide it by -30 because its being tiems by a number we cant see

so -30/3 = -10

Thats how we found X.

Answer:

Solve for x

Step-by-step explanation:

we already know that 30 minus 15 is 15 so something times 3 equals 30. 10x3=30. so x = 10.

15 =3(10)-15

15= 3(10) -15 =30 -15

15 = 30 - 15

15=15

So, again, the answer is 10.

Find the value of the variable y, where the sum of the fractions 6/(y+1) and y/(y-2) is equal to their product.

Blizzard [7]

Answer:

The answer is

$y = 3$

$y = - 4$

Step-by-step explanation:

We must find a solution where

$\frac{6}{y + 1} + \frac{y}{y - 2} = \frac{6}{y + 1} \times \frac{y}{y - 2}$

Consider the Left Side:

First, to add fraction multiply each fraction on the left by it corresponding denomiator and we should get

$\frac{6}{y + 1} \times \frac{y - 2}{y - 2} + \frac{y}{y - 2} \times \frac{y + 1}{y + 1}$

Which equals

$\frac{6y - 12}{(y -2) (y + 1)} + \frac{ {y}^{2} + y }{(y - 2)(y + 1)}$

Add the fractions

$\frac{y {}^{2} + 7y - 12 }{(y - 2)(y + 1)} = \frac{6}{y + 1} \times \frac{y}{y - 2}$

Simplify the right side by multiplying the fraction

$\frac{6y}{(y + 1)(y + 2)}$

Set both fractions equal to each other

$\frac{6y}{(y + 1)(y - 2)} = \frac{ {y}^{2} + 7y - 12}{(y + 1)(y - 2)}$

Since the denomiator are equal, we must set the numerator equal to each other

$6y = {y}^{2} + 7y - 12$

$= {y}^{2} + y - 12$

$(y + 4)(y - 3)$

$y = - 4$

$y = 3$

Who wants to help me on question 41. I don't understand what it means when it says "label a net".

Novosadov [1.4K]

A net is basically a flattened out 3D solid. If you fold all the sides up, you would end up with the 3D model.
