Question

0,8(3a-14)-0,6(6a-8)​

Answer 1

0,8(3a-14)-0,6(6a-8)

1) 0,8(3а-14)=2,4а-11,2

2) 0,6(6а-8)=3,6а-4,8

3) 2,4а-11,2-(3,6а-4,8)=2,4а-11,2-3,6а+4,8=-1,2а-6,4

Ответ: после упрощения получится -1,2а-6,4

Answer 2

Ответ:

2.4а-11.2-36а-4.8

2.4*(-3)-11,2-3,6+ 4.8=-1.2а-6,4

Answer 3

It looks like you're providing an algebraic expression, and it appears to be a mixture of numbers and variables. To simplify this expression, let's perform the calculations step by step:

Given expression: 0.8(3a - 14) - 0.6(6a - 8)

Step 1: Distribute the constants and variables within each set of parentheses:

0.8 * 3a - 0.8 * 14 - 0.6 * 6a + 0.6 * 8

Step 2: Perform the multiplications:

2.4a - 11.2 - 3.6a + 4.8

Step 3: Combine like terms (terms with the same variable raised to the same power):

(2.4a - 3.6a) + (-11.2 + 4.8)

-1.2a - 6.4

So, the simplified expression is -1.2a - 6.4.
