A school group is helping plant a new city garden. Today they used 12 1/2 pounds of potting soil and planted 2/5 of the garden.

Len [333]

Answer:

$18\frac{3}{4}$ pounds.

Step-by-step explanation:

Let x be the total amount of potting soil needed to complete the planting in new garden.

We are told that a school group is helping plant a new city garden. Today they used 12 1/2 pounds of potting soil and planted 2/5 of the garden. This means 2/5 of x equals to 12 1/2.

$\frac{2}{5} x=12\frac{1}{2}$

$\frac{2}{5} x=\frac{25}{2}$

$x=\frac{25}{2}\times\frac{5}{2}$

$x=\frac{125}{4}$

To find the amount of soil needed for the next of planting we will subtract the amount of potting soil used on the first day $(\frac{25}{2})$ from amount of total potting soil $(\frac{125}{4})$ .

$\text{Amount of potting soil needed for second day}=\frac{125}{4}-\frac{25}{2}$

$\text{Amount of potting soil needed for second day}=\frac{125}{4}-\frac{25\times 2}{2\times2}$

$\text{Amount of potting soil needed for second day}=\frac{125}{4}-\frac{50}{4}$

$\text{Amount of potting soil needed for second day}=\frac{75}{4}$

$\text{Amount of potting soil needed for second day}=\frac{75}{4}=18\frac{3}{4}$

Therefore, the group will need $18\frac{3}{4}$ pounds of potting soil to finish their work.

Solve this system of equation using the substitution method<br><br> 2x + y = 5<br><br> y = x - 4

Amanda [17]

Answer:

$\boxed {\boxed {\sf (3, -1)}}$

Step-by-step explanation:

We are asked to solve this system of equations using substitution:

$2x+y=5\\y=x-4$

Since y is equal to x-4, we can substitute x-4 in the top equation.

$2x+(x-4)=5$

$2x+x-4=5$

Combine the like terms on the left side of the equation. 2x and x both have the variable x and can be added.

$3x-4=5$

Now, solve for x by isolating the variable. 4 is being subtracted and the inverse of subtraction is addition. Add 4 to both sides.

$3x-4+4=5+4\\3x=5+4\\3x=9$

x is being multiplied by 3 and the inverse of multiplication is division. Divide both sides by 3.

$3x/3=9/3 \\x=9/3 \\x=3$

x is equal to 3. Substitute 3 back into the bottom equation to find y.

$y=x-4\\y=3-4\\y=-1$

Points are written as (x,y). The solution to this system of equations is (3, -1).
