4z +  2 = 10z - 1

Add sides 1

4z  + 2  + 1 = 10z - 1 + 1

4z + 3 = 10z

Subtract sides 4z

- 4z + 4z + 3 =  - 4z + 10z

3 = 6z

6z = 3

Divide sides by 6

\frac{6z}{6}  =  \frac{3}{6}  \\

z =  \frac{1}{2}  \\

3y = y + 3

Subtract sides y

- y + 3y =  - y + y + 3

2y = 3

Divide sides by 2

\frac{2y}{2}  =  \frac{3}{2}  \\

y =  \frac{3}{2}  \\

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Thus the correct answer is :

a) \: y =  \frac{3}{2}  \: , \: z =  \frac{1}{2}  \\

One of the main contaminants of a nuclear accident, such as that at Chernobyl, is strontium-90, which decays exponentially at a
igor_vitrenko [27]

Answer: P=0.975^t


Step-by-step explanation:

We know that the general form of the exponential decay formula is


y=A(1-r)^t, where y is final amount remaining after t time, A is the original amount and r is the rate of decay


Now, the ratio of strontium-90 remaining, p , as a function of years, t , since the nuclear accident. P=\frac{A(1-0.02)^t}{A}=\frac{(0.975)^t}{1}

Hence, the ratio of remaining since the nuclear accident is P=0.975^t
