Vous divisez la longueur totale (120) par la longueur de chaque morceau (8). 120 ÷ 8 = 15 morceaux.La vitesse moyenne est la distance totale ÷ le temps total. 150 ÷ 3 = 50 mph.Périmètre = 2 × (longueur + largeur). 64 = 2 × (20 + largeur) → 32 = 20 + largeur → largeur = 12 cm.Additionnez les coûts : 12,75 + 18,25 = 31. Soustrayez de 50 $ : 50 – 31 = 19 $.Soit la largeur = x, la longueur = 3x. Périmètre = 2 × (x + 3x) = 8x. 8x = 48 → x = 6 → longueur = 18, largeur = 6.Si crayons = 3 × stylos, alors stylos = crayons ÷ 3. 24 ÷ 3 = 8 stylos.Les angles totalisent 180°. x + 2x + (x + 30) = 180 → 4x + 30 = 180 → 4x = 150 → x = 37,5.2n – 7 = 17 → 2n = 24 → n = 12.1/4 × 320 = 80 pages.4 × 3 $ = 12 $. Soustrayez de 20 $ → 20 – 12 = 8 $.C'est une division simple : 144 ÷ 12 = 12.25 % de 24 est 6, et 24 $ - 6 $ = 18 $.Multipliez 200 × 3/5 = 120.9 × 9 = 81.Divisez les deux côtés par 8 → x = 8.3 × 2,50 $ = 7,50 $.Aire = côté × côté → 6 × 6 = 36.60 × 0,15 = 9.300 ÷ 4 = 75.45 ÷ 5 = 9.250 % = 2,5 × 20 = 50.20 – 12,80 = 7,20.3/4 = 0,75, 5/8 = 0,625.2 × (7 + 5) = 24.2 × 2 × 2 = 8.100 – 40 = 60.Les angles d'un triangle totalisent toujours 180°.5 × 2 = 10, puis placer la décimale → 0,1.8 – 3 = 5 parts restantes → 5/8.(6 + 8 + 10) ÷ 3 = 8.Ajouter 5 → y = 17.2 heures = 120 min, plus 30 min = 150.15 × 14 = 210.25 + 9 = 34.10 ÷ 5 = 2.0,25 = 1/4.12 – (–3) = 15.14, 15, 16 ne sont pas premiers ; 17 l'est.20 ÷ 4 = 5.√49 = 7.You scored 0 out of 40You scored 1 out of 40You scored 2 out of 40You scored 3 out of 40You scored 4 out of 40You scored 5 out of 40You scored 6 out of 40You scored 7 out of 40You scored 8 out of 40You scored 9 out of 40You scored 10 out of 40You scored 11 out of 40You scored 12 out of 40You scored 13 out of 40You scored 14 out of 40You scored 15 out of 40You scored 16 out of 40You scored 17 out of 40You scored 18 out of 40You scored 19 out of 40You scored 20 out of 40You scored 21 out of 40You scored 22 out of 40You scored 23 out of 40You scored 24 out of 40You scored 25 out of 40You scored 26 out of 40You scored 27 out of 40You scored 28 out of 40You scored 29 out of 40You scored 30 out of 40You scored 31 out of 40You scored 32 out of 40You scored 33 out of 40You scored 34 out of 40You scored 35 out of 40You scored 36 out of 40You scored 37 out of 40You scored 38 out of 40You scored 39 out of 40You scored 40 out of 40
