You can first convert everything to ounces and then subtract, when you get your answer convert it back to lbs.
*16 oz = 1 lb
12 lbs 5 oz = 197 oz
7lbs 10 oz = 94 oz
197 - 94 = 103
103/16
= 4 lbs and 7 oz
hope this helps :)
Answer:
1500 J is the correct answer.
Step-by-step explanation:
“ negation “ would be used
You multiply 19 × 2.54 to convert it to cm
X-intercepts are points where the graph intersects the x-axis, i.e. when y=0.
Substitute y=0 and solve for x:
y=x^2-3x+2
0=x^2-3x+2
0=(x-2)(x-1)
By the zero product property, we deduce x-2=0 or x-1=0, i.e. x=1 or x=2.
