Use the Distributive Property to solve the equation. 2/3 (6a+9)=16.8

HELP ME

2.7

Step-by-step explanation:

multiply 2/3 by the 6a and the 9 and you get:

4a + 6 = 16.8

move the 6 over by subtraction

4a = 10.8

divide by 4

a = 2.7

Step-by-step explanation:

change 2/3 to a decimal round to the nearest tenth

.7 (6a + 9) = 16.8

.7 x 6a = 4.2a

.7 x 9 = 6.3

4.2a + 6.3 = 16.8

4.2a = 16.8 - 6.3

4.2a = 10.5

a = 10.5 / 4.2

a = 2.5

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
