Ok let me explain it to you like this:
Let the price for one egg be x and the price for one toast be y Then: <span><span>3 = </span><span><span>2x+1y,
</span><span>1.8 = 1x+1y.</span></span></span><span>When we substract, we get x = 1.2 and y = 0.6, so the price for an egg is $1.20 and the price for a toast is $0.60.
</span>Hope this is helpful

Answer:
The answer is 4
Step-by-step explanation:
Set them equal so it would be X-3= -X+5 then add the negative X to get
2x-3=5 then add the -3 to 5 and get
2x=8 then divide 2 from both sides to get
x=4
Answer:
7.3025850929
Step-by-step explanation:
v(t)=(2t)/(1+t^2)
To find the position we need to integrate the function
p(t) = ∫ v(t)
p(t) =∫(2t)/(1+t^2) dt
Using u substitution
u = 1+t^2
du =2t dt
p(t) =∫(du)/(u)
We know that the integral of 1/u du is ln |u|
p(t) = ln|u| +C
Substituting back for u
p(t) = ln|1 +t^2| +C
To find the value of C, we let t=0
p(0) = ln|1 +0| +C = 5
= ln(1) +C =5
0 +C =5 Therefore C=5
p(t) = ln|1 +t^2| +5
We want to find the position at t=3
p(3) = ln|1 +3^2| +5
= ln(10) +5
