Answer: subtract 12-4
Step-by-step explanation:
For the range you subtract the smallest number from the biggest number so 12-4.
<span>-4p-7=5p+11
-4p - 5p = 11 + 7
-9p = 18
p = -2</span>
Nothing "weighs" 56.7 grams. "Gram" is a unit of mass, not force or weight.
On Earth, 28.35 grams of mass weigh about 1 ounce .
1 dozen of anything = 12 of them
If each tennis ball has 56.7 grams of mass, then a dozen of them
have
(12) x (56.7) = 680.4 grams of mass .
Their weight is (680.4 grams) x (1 ounce / 28.35 grams) =
(680.4 / 28.35) = 24 ounces.
That's 1.5 pounds.
4(8 + 3x)
4(8) + 4(3x)
32 + 12x
643=4x160+n =that is the problem
n=3
