-1-2x=7-4x whats the value that makes it true ?

x = 4

Step-by-step explanation:

To find what value makes the expression -1 - 2x = 7 - 4x true, we can solve for x in the expression.

-1 - 2x = 7 - 4x

Add 1 to both sides.

-2x = 8 - 4x

Add 4x to both sides.

2x = 8

Divide both sides by 2.

x = 4

So after solving for x in the expression, we have found the x = 4. So the value of 4 for x would make the expression true.

I hope this helps. Happy studying.

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
