Linear equations 3(x+1)=3x+3
vaieri [72.5K]
4x + 2 - 3x + 5 - 2(x + 5) = (2x - 5) + (3x + 4) 
4x + 2 - 3x + 5  - 2x - 10 =   2x - 5 +   3x + 4 
4x - 3x - 2x + 5 + 2 - 10  =  2x + 3x - 5 + 4

    -3   = 6x - 1 
<span>    +1   =    + 1 </span>

A bag with 2 1/2 quarts of peanuts can make 2 1/6 jars of peanut butter. How many
diamong [38]

Answer:

You will need 3 6/13 quarts of peanuts to make 3 jars of peanuts butter

Step-by-step explanation:

To make this answering seamless, we make the mixed fractions into improper fractions

Hence 2 1/2 becomes 5/2

while 2 1/6 becomes 13/6

Here we are told that a bag with 5/2 quarts of peanuts can make 13/6 jars of peanuts butter

Hence, x quarts of peanuts will make 3 jars of peanuts butter

To get the value of x, what we simply need to do is to cross multiply.

Thus, we have

5/2 - 13/6

x - 3

3 * 5/2 = 13/6 * x

15/2 = 13x/6

26x = 90

x = 90/26

x = 45/13

x = 3 6/13

Find two numbers if their sum is 6.1 and their difference is 1.6
Radda [10]
For this case, the first thing we must do is define variables:
 x: unknown number (1)
 y: unknown number (2)
 We now write the equations that model the problem:
 their sum is 6.1:
 x + y = 6.1&#10;
 their difference is 1.6:
 x - y = 1.6&#10;
 Solving the system we have:
 We add both equations:
 x + x = 6.1 + 1.6&#10;&#10;2x = 7.7&#10;&#10;x = 7.7 / 2&#10;&#10;x = 3.85
 Then, we look for the value of y using any of the equations:
 x - y = 1.6&#10;&#10;y = x - 1.6&#10;&#10;y = 3.85 - 1.6&#10;&#10;y = 2.25
 Answer:
 
The numbers are:
 
x = 3.85&#10;&#10;y = 2.25
