Answer:
Step-by-step explanation
Answer:
4x^2-5x+1=0
=4x^2-x-4x+1=0
The second 4x is because of 5x=-x-4x
=xmultiply(4x-1)-4x-1)=0
=(4x-1)x(x-1)=0
=4x-1=0
Another value for x is
x-1=0
Final
=x=1/4
=x=1
Finally the answers are
Value of first X is
X=1/4
Value of second X is
X=1
Answer:
<h2>11.25min</h2>
Step-by-step explanation:
In this problem, we first need to find the rate at which syn burns calories per minute
so in 15mins, he burns 200 calories
in 1 mins he will burn x
x= 200/15
x=13.33 calories per min this is the rate
So in one minute he will burn 13.33 calories
Now using the idea of rate=quantity/time
the rate=13.33
quantity=15 calories
time=?
time=quantity/rate
time=150/13.33
time=11.25min
Alternatively
(very fast approach)
if syn spend 15min to burn 200 cal
then he will spend x min to burn 150 cal
cross multiply
x=(150*15)/200
x=2250/200
x=11.25mins
Answer:
10 units
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
you just Multiply by 2
First, you would need to create an equation for this problem. Let x represent the unknown tax.
=
Next, you would cross multiply.
100x = 52.5
Now, all you would have to do is isolate the x. To do this, you would divide both sides by 100.
x = $0.525I hope this helps!
