The x intercepts were supposed to be x = 3, 7
Answer:
42cm³
Step-by-step explanation:
7*2*3=42
7*2=14
14*3=42
42
Multiply the second equation by 3
-4x+9y=9
3x-9y=-18
add the equations together
-x=-9 Simplify
x=9
now plug in your x value
(9)-3y=-6 Simplify
-3y=-6-9
-3y=-15
y=5
Given:
13 pounds and 7 ounces
convert to kilograms:
1 kilogram = 2.20462 pounds
1 kilogram = 35.274 ounces
13 pounds * 1 kg/2.20462 pounds = 13 kg/2.20462 = 5.8967 kg
7 ounces * 1kg/35.274 ounces = 7 kg/35.274 = 0.1984
5.8967 kg + 0.1984 = 6.0951 kg. rounded up to 6.10 kgs.
