Order the following from greatest to least: -12,12,-19,1 and 1/2,5.....
den301095 [7]
-19, -12, 1/2, 1, 5, 12 ----> least to greatest
12, 5, 1, 1/2, -12, -19 ----> greatest to least

Do the same as the last one, starting with the largest negative number, and ending with the largest positive number.  The only difference in this case is that it is greatest to least.  I tend to go from least to greatest first and then flip it around to get greatest to least (:

4x - y = 5 --> 4x = y + 5

substitute

4x + 4y = -4

(y + 5) + 4y = -4

5y + 5 = -4

5y = -9

y = -1.8

solve x

4x = y + 5 = -1.8 + 5 = 3.2

x = 3.2/4 = 0.8

Bonjour je ne comprend pas cette exercice; si quelqu'un peut m'aider je suis preneuse.
gayaneshka [121]

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.
