-6+k÷5=-9 how do we work this out

1 answer:

3 0

First you have to multiply both sides by -5 which means you will multiply -5 by 6, -5 by k/5, and -5 by 9... So it should look like: -5×6+-5×k/5=-5+9.. after that.. it should look like -40+k=-45.. because the 5's in k/5 cancel out.. so then it should now look like k=-45+30... you subtract.. and k=-15

Answer:

0,24 m

Step-by-step explanation:

La table est un rectanble donc l'angle en haut à droite est de 90°.

Tu connais donc un angle et le côté opposé à l'angle et tu cherche le côté adjacent.

On sait que tan(â) = $\frac{Cote oppose}{Cote adjacent}$ donc :

tan(40)= $\frac{1,27}{x}$

$\frac{1,27}{tan(40)} = x$

donc x ≈ 1,51 m

Le trou du mileu est à $\frac{2,54}{2}$ soit 1,27m du bord.

Donc elle doit taper à 1,51 - 1,27 = 0,24m du trou du milieu.

j'espère avoir été clair.
