Answer:
7. 9 kg
a) 4 cm
Step-by-step explanation:
7. ¾ of 12
¾×12
3×3 = 9
a) ⅔ of 6
⅔×6
2×2
4 cm
7. Multiply the mass of the porcupine by the raccoons portion:
12 x 3/4 = (12 x 3)/4 = 36/4 = 9kg.
8. Multiply both numbers:
6 x 2/3 = (6x2)/3 = 12/3 = 4cm
I believe the answer is C
6+7= 13
you replace a with 7
60+3y =15
3y =15-60
3y =-45
y=-15
