Step-by-step explanation:
1.
4(3x + 2) = 4(2x + 3) + 4x do the multiplying
2.
12x + 8 = 8x + 12 + 4x export like terms to the same side of the equation and add/subtract like terms
3.
12x - 12x = 4
4.
0 = 4 this is not an equation so there's no solution to this one equation
1.
10(x + 4) - 3 = 14x + 1 do the multiplying
2.
10x + 40 - 3 = 14x + 1 export like terms to the same side of the equation and add/subtract like terms
3.
36 = 4x
9 = x there's one solution to this equation
1.
1/2 (10x + 15) - 3/2 = 2x + 6 + 3x do the multiplying
2.
(10x + 15)/2 - 3/2 = 5x + 6 export like terms to the same side of the equation and add/subtract like terms
3.
(10x + 12)/2 = 5x + 6 multiply both sides with 2 so we can get rid of fraction
10x + 12 = 10x + 12
0 = 0 there's infinetly many solutions to this equation meaning whatever number written instead of x there will a solution.
Answer:
Step-by-step explanation:
so to solve this you have to be smart.
6yd and 5y^2
s.a=2lw+2wb
yb=86/7 = 42/855
9/6=2 and 2^2=4
therefore leaving us with 87in^2
ez stuff just think
Answer:1. find the intersection, 2.) 0 and 1, 3,) 2 and 3, 4.) 0.4, 2.8
Step-by-step explanation:
Answer: Medication in Lexi's system on day t becomes,
Step-by-step explanation:
Since we have given that
Initial amount Sofia takes of a medicine = 10 mg
Concentration in blood decreases by a factor of one half every day.
So, it becomes,
According to question, four days later, it becomes,
We have given that Lexi takes 10 mg of the same medicine.
So, it becomes,
Hence, Medication in Lexi's system on day t becomes,
