Answer:
Step-by-step explanation:
let my present age=x
then 2(x-5)=x+2
2x-10=x+2
2x-x=2+10
x=12
my age=12 years
age of brother =12-3=9 years
age of sister= 9-2=7 years.

The slope will be 200 since it increases by two hundred per week
The equation for this would be
y = 200x
8.
J would be the best table
Triangle area = base*height)2
Here, area = 23*28/2=322
Answer:
26.3 grams
Step-by-step explanation:
57% of fiber is 15 grams. To find 1% you would divide 15 by 57 which is 0.2631578947. Now multiply 1% by 100 to get 100% fiber. The amount of fiber needed per day is 26.31578947 (the rounded answer is 26.3)
