solve for z: 3z – 10 = 2 + 4z
(1 point)
z= 1
z= 5
z= -7
z= -12

how many years would it take to make 1 billion dollars if someone makes $63,930 a year?
(1 point)
about 10 thousand
about 13 thousand

Explanation:

Step1: Isolate z terms

Subtract $3z$ from both sides:
$3z - 10 - 3z = 2 + 4z - 3z$
$-10 = 2 + z$

Step2: Solve for z

Subtract 2 from both sides:
$-10 - 2 = 2 + z - 2$
$z = -12$

Step3: Calculate years for $1B$

Divide total by annual income:
$\text{Years} = \frac{1,000,000,000}{63,930}$
$\text{Years} \approx 15642$ (closest to "About 16 thousand", but based on visible options, the logical calculated value shows the visible options are incomplete, but for the first question:

Answer:

z = -12

For the second question: The full set of options is not provided, but the calculated value is approximately 15,642 years, which is closest to "About 16 thousand" (not shown). Based on the visible partial options, none match the precise calculation, but the mathematical result is $\approx 15642$ years.
