Answer:

a=2

Step-by-step explanation:

8a +9=3a +19

Subtract 9 from both sides

-9= -9

8a=3a +10

Subtract -3a from both sides

5a=10

5a divided by both sides

5/5

10/5=2

a=2

soldier1979 [14.2K]

Answer:

2 1/2 = 5/2

Step-by-step explanation:

There is a trick you can do when converting mixed numbers into improper fractions

Multiply the whole number and denominator, in this case you'll do 2 * 2 which equals 4

Finally, add the numberator to your product. For this you'll do 4 + 1 which equals 5

When done, keep the denominator and keep your sum as the numerator. 5/2!

Reptile [31]

Answer:

$\dfrac{17}{45}$

Step-by-step explanation:

Fraction on which Rosemary was planted $=\dfrac{2}{9}$

Fraction on which dill was planted $=\dfrac{2}{5}$

Let the fraction on which chives was planted=x

Then:

$\dfrac{2}{9}+\dfrac{2}{5}+x=1\\$Since the LCM of 9 and 5 is 45\\We multiply all through by 45\\45\left(\dfrac{2}{9}\left)+45\left(\dfrac{2}{5}\right)+45x=45(1)$\\10+18+45x=45\\45x=45-28\\45x=17\\Divide both sides by 45\\x=\dfrac{17}{45}$

The fraction of the garden on which Chives was planted is $\dfrac{17}{45}$
