Question

1) - 8(3x + 5) - 15x + 35 ; 2) 2, 1t - 0, 5(4t + 0, 3) - t ;​

Answer 1

Ответ:

Пошаговое объяснение:

1)=-24х-40-15х+35=-39х-5

2)=2,1t-2t+0,15-t=-0,9t+0,15

Answer 2

Пошаговое объяснение:

1)-8*3х+(-8*5)-15х+35=

-24х-40-15х+35=

-39х=-35+40

-39х=5

39х=5

х=5:39

х=

$\frac{5}{39}$

Answer 3

Sure, let's simplify the given expressions:

1. $-8(3x + 5) - 15x + 35$

To simplify this expression, distribute the $-8$ to $3x$ and $5$:

$-8 \times 3x - 8 \times 5 - 15x + 35$

$-24x - 40 - 15x + 35$

Combine like terms:

$-24x - 15x - 40 + 35$

$-39x - 5$

So, the simplified form of the first expression is $-39x - 5$.

2. $2, 1t - 0, 5(4t + 0, 3) - t$

To simplify this expression, first distribute $-0.5$ to $4t$ and $0.3$:

$2.1t - 0.5 \times 4t - 0.5 \times 0.3 - t$

$2.1t - 2t - 0.15 - t$

Combine like terms:

$2.1t - 3t - 0.15$

$-0.9t - 0.15$

So, the simplified form of the second expression is $-0.9t - 0.15$.
