$Solving \ an \ equation \ means \ finding \ a \ value \ of \ a \ variable$ $that \ make \ the \ equation \ true.$

$Each \ sides \ of \ the \ equation \ should \ be \ equal \ at \ all \ times.

$ $Whatever \ we \ do \ to \ one \ side, has \ to \ be \ done \ on \ the \ opposite \ side.$

sheldon bought 4 1/2 kg of plant food. he uses 1 2/3 kg on his strawberry plant and used 1/4 kg for his tomato plant. how many k

fenix001 [56]

Answer:

Sheldon have left $2\frac{7}{12}\ kg$ of food.

Step-by-step explanation:

Quantity of food = $4\frac{1}{2}=\frac{9}{2}$ kg

Quantity used on strawberry plant = $1\frac{2}{3} = \frac{5}{3}\ kg$

Quantity used on tomato plant = $\frac{1}{4}\ kg$

Food left = Total - used on strawberry - used on tomato

Food left = $\frac{9}{2}-\frac{5}{3}-\frac{1}{4}$

Food left = $\frac{54-20-3}{12} = \frac{31}{12}$

Food left = $2\frac{7}{12}\ kg$

Therefore,

Sheldon have left $2\frac{7}{12}\ kg$ of food.

natka813 [3]

Answer:

Step-by-step explanation:

When evaluating absolute values, a great way to remember what they do is simple. No matter the number, whether it is negative or positive, the number(s) IN THE absolute values are ALWAYS positive.

So, |x + y| is then substituted with the numbers given for the variables.

|x + y|

|8 - 15|

|-7|

8+11 X = 9X +4+ 2X Solve x

Irina18 [472]

We want to get x by itself so we combine like terms first.
First subtract 4 from both sides
4+11x=9x+2x
Now add 9x and 2x together
4+11x=11x
Subtract 11 from both sides
4=0
The equation is false.
