Answer:
use math- way for those and your other homework i promise it'll work!
Step-by-step explanation:
Domik weights 30 pounds more than his sister
Together they weigh 330 pounds
Let "x" represent the weight of Dominik's sister, then his weight can be expressed as "x+30"
And their total weight can be calculated as:
From this expression you can calculate the value of x:
x=150 pounds
x+30=150+30=180 pounds
Dominik weights 180pounds and his sister 150 pounds
Answer:
see the procedure
Step-by-step explanation:
we know that
so
The value of digit 8 in 1.8 is 0.8
The value of digit 8 in 486 is 80
Divide the numbers
80/0.8=100
therefore
The value of the digit 8 in 486 is 100 times greater than the value of digit 8 in 1.8
or
The value of the digit 8 in 1.8 is 100 times less than the value of digit 8 in 486
Total ribbons would be the sum of two numbers.
So, x = 29 + 17 = 46
In short, Your Answer would be: 46 ribbons
Hope this helps!
