Answer:

x = 11

Step-by-step explanation:

(3x + 28) + (5x + 52) + ( 2x - 10) = 180

(3x + 5x + 2x) + (28 + 52 - 10) = 180

10x + 70 = 180

10x = 180 - 70

10x = 110

x = 11

Answer:

x= 11

Step-by-step explanation:

(3x + 5x) + (5x+52) + (2x-10)= 180 (sum of anglea in a triangle)

10x+80-10= 180

10x+70=180

10x=180-70

10x=110

x=110÷10

x=11

fgiga [73]

Answer:

Wayne west would have $5,015 in six months

Step-by-step explanation:

The formula for exponential regression model is y = αβˣ

Where y is amount of money in 1000 dollars

x is time in months

We are given that α = 4.2 and β = 1.03 and x = 6 months

Therefore, based on this model, y = αβˣ, the amount he would have in 6 months, y = $4.2*(1.03) ^{6}$

y = 5.015 × 1000 = $ 5,015
