-3x + 18 = 7x solve

Mathematics

Answer: x = 1.8

-3x + 18 = 7x
First, isolate the variable. There’s a couple ways to do this. One is to subtract 7x from each side and subtract 18 from each side. The other is to add 3x to both sides. Either way, you end up with all the variables on one side and the rest on its own.

This would give us either…
-10x = -18
OR
18 = 10x

From there, divide by 10 to get a single x

-x = (-18/10)
-x = -1.8
Multiply each by -1 to find what positive x equals
x = 1.8
OR
(18/10) = x
1.8 = x

Solve the equation... 10x - 12 = 48 - 2x
hjlf
If you would like to solve the equation 10 * x - 12 = 48 - 2 * x, you can calculate this using the following steps:

10 * x - 12 = 48 - 2 * x
10 * x + 2 * x = 48 + 12
12 * x = 60   /12
x = 60 / 12
x = 5

The correct result is 5.

How do you find the area of a rectangle​
natka813 [3]

Answer:

You multiply length by width.

Step-by-step explanation:

To find the area of a rectangle you multiply length and width together.

For example if a rectangle has length 2 and width 3 the area of the rectangle would be 6, since 2 * 3 is 6.

A punch recipe that serves 24 people calls for 4 liters of lemon-lime soda, 2 pints of sherbet, and 6 cups of ice. How much of e
nasty-shy [4]

Answer:

For 12 people, the identical recipe that would serve this amount would be 2 liters of lemon-lime soda, 1 pints of sherbet, and 3 cups of ice.

To figure out the corresponding proportion from 24 servings to 12 servings, first we divide 24 by 12, which is 2. The number 2 represents how many times bigger the original recipe is to the smaller 12 servings version, which mean the 24 people version would be twice as big compared to the 12 people serving. So all we have to do to the recipe is divide it in half. And so 4 liters divided by 2 is 2 liters of lemon-lime soda, 2 pints of sherbet becomes 1 pint, and 6 ice cups turns into 3 cups of ice.
