Find the value of x, please help

x=33

Step-by-step explanation:

x+(3x+48)=180

combine like terms

4x+48=180

subtract 48 from 180

4x=132

then you divide both sides by 4

x=33.

check your work (plug it in)

33+((33x3)+48)=180

33x3=99

99+48=147

then you add 33 from the other x

147+33=180

answer: a clock

step-by-step explanation:

(a) {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …}

(b) $59 398

step-by-step explanation:

(a) the annual sequence of profits

aₙ = a₁rⁿ⁻¹

the model for the sequence of profits is {a₁, a₁r, a₁r², … a₁rⁿ⁻¹, …} .

(b) profit after 15 yr

  a₁ = $ 30 000

  r = 1.05

a₁₅ = 30 000 × 1.05¹⁴

a₁₅ = 30 000 × 1.979 93

a₁₅ = $59 398

the profit in year 15 will be $59 398.
