3(1/2) in fraction form NO DECIMALL FORM
Sever21 [200]
First just make the whole number a fraction.
3 in fraction form is 3/1.
Now make it have a common denominator with the fraction 1/2.
Just multiply both the numerator and denominator by 2.
This gives you 6/2
Now add!
6/2 + 1/2 = 7/2
So 3(1/2) = 7/2.

Please explain I just started learning this
Digiron [165]

Answer:

x=5

y=7

Step-by-step explanation:

y = x+2 so plug that in the next equation as y

so it be --> 5x+(-4)(x+2)= -3 now use distributive property

(-4 times x)+(-4 times 2)= -4x+-8 replug that back in

5x-4x+-8 = -3 subtract your x

1x = x so ---> x+-8 = -3 now to get rid of -8 we have to add 8 to it

x= -3 but whatever you do to one side u do to the other so u have to add 8 to -3---> so it be x=5

now take that x=5 and plug it in to your first eqaiuton to get y

y=5+2 ---> y =7

Can somebody help me with this :) ??
rjkz [21]

Answer:

A. (5,9)

Step-by-step explanation:

First, you need to reflect across the line of reflection. Since the point is 7 units from the line y=2 from one side, it will be 7 units away when it is reflected. 2+7=9, so the reflected coordinates of the point are (-2,9). For the glide translation, you slide the point 7 units to the right, placing it at the final location of (5,9). Hope this helps!

a 29 gram sample of a substance that's used to preserve fruits and vegetables has a k-value of 0.1359. Find the substance's half
kaheart [24]
Okay well
a(t)= amount of substance remaining after t days
assuming exponential decay, a(t)=29e^-0.1359t

now, find the half, set a(t)= half the original and solve for t

14.5=29e^-0.1359t
0.5=e^-0.1359t
In(0.5)=In(e^-0.1359t)
In(0.5)=-o.1359t

t=in(0.5)/(-0.1359)= (aprox) 5.1 days
