Answer:
3 days
Step-by-step explanation:
do this when its a percent move the decimal twice to the left so now its .10 multiply it by 30 days
Answer:
1 is 20
Step-by-step explanation:
<span> by putting values from periodic tabl H2(2 x 1.007947 g H/mol ) + S(32.0655 g S/mol) + 04(4 x 15.99943 g O/mol) =
98.0791 g H2SO4/mol is the answer hope it helps</span>
you move first the number without the variable to the other side with the opposite sign
-0.75p=0.25+2
-0.75p=2.25
then as -0.75 is multiplying you pass it to the other side dividing
p=2.25/-0.75
p=-3
4a^2+7ab-b^2
Step-by-step explanation:
Add the first two equations together:
3a^2-ab-2b^2
+ 2a^2+5ab-3b^2
---------------------------
5a^2+4ab-5b^2
Subtract that answer from the remaining trinomial:
5a^2+4ab-5b^2
- a^2-3ab-4b^2
--------------------------
4a^2+7ab-b^2
