5a - 9 + a = 9

Ne4ueva [31]

Answer:

a = 3

Step-by-step explanation:

1) Simplify 5a - 9 + a to 6a - 9.

$6a - 9 = 9$

2) Add 9 to both sides.

$6a = 9 + 9$

3) Simplify 9 + 9 to 18.

$6a = 18$

4) Divide both sides by 6.

$a = \frac{18}{6}$

5) Simplify 18/6 to 3.

$a = 3$

Therefor, the answer is, a = 3.

Factor each completely. <br><br>10a² - 9a + 2 <br><br>

Sophie [7]

Answer:

a= $\frac{2}{5}$ or $\frac{1}{2}$

Step-by-step explanation:

Equate the equation to zero

$10a^{2}$ -9a+2=0

$10a^{2}$ -5a-4a+2=0

5a(2a-1)-2(2a-1)=0

Write out the factors

(5a-2)(2a-1)=0

Then equate each factor to zero

5a-2=0 OR 2a-1=0

5a=2 OR 2a=1

a= $\frac{2}{5}$ OR a= $\frac{1}{2}$

a= $\frac{2}{5}$ or $\frac{1}{2}$
