Answer:
the answer is 20m/s
Step-by-step explanation:
speed = distance/time which equals to speed = 800/40, so the answer is 20m/s
5x(x+6)=-50
X(x+6)=-10
X square +6x=-10
(X+3) square=-10-9
(X+3) square=-19
So this equation has no solution
Answer:
If there is "p" pounds of peanuts and "m" pounds of '20% peanuts and 80% almonds' mixture, then, we can get the following equations,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
whose solution is 5 lb peanuts and 5 lb mixture.
Step-by-step explanation:
In the mixture which Delaney wants to make there would be
lb
= 6 lb of peanuts
So, there will be (10 - 6) lb
= 4 lb of almonds
If Delaney has "p" pounds of peanuts and "m" pounds of the '20% peanuts and 80% almonds' mixture, then according to the question,
p + m = 10 -----------(1) and
4m/5 = 4 ------------(2)
So, from (2),
m = 5 --------------(3)
So, from (1) and (3) ,
p = (10 - 5) = 5
Let's say each side is 5 and 5 so all you have to do is times 5 bye 5 and divide the two numbers by 20 and when you get that then you add the numbers by 180 then your answer is 239cm
Well you'd see if it's closer to 10000 or 20000.
In this case it would round to 20000.
