3a+20=-25

Subtract 20 from both sides
3a=-45

Divide both sides by 3
a=-15

Final answer: a=-15

What is the equation 8x-3y=6-4x in Stanford form?

IgorLugansk [536]

Answer:

$12x - 3y = 6$

Step-by-step explanation:

Standard form is written this way: $Ax+By=C$

However, in this case, we just have to simplify 8x-3y=6-4x, as it is already mostly in standard form.

So, to do this, we have to combine like terms.

The only like terms that can be combined are -4x and 8x.

So, we add 4x to both sides, and we get: $12x - 3y = 6$ .

The sum of a number times 7 and 21 is at least 29. Write as an inequality

PtichkaEL [24]

The inequality is 7x + 21 $\leq 29$

Step-by-step explanation:

DATA:

Let the number be x

Number times 7 = 7*x

Sum of a number times 7 and 21 = 7x + 21

Is at least 29

INEQUALITY:

7x + 21 $\leq 29$

SOLVE:

7x $\leq 29-21$

7x $\leq 8$

x $\leq \frac{8}{7}$

Therefore, the inequality is 7x + 21 $\leq 29$
