The measures of two supplementary angles are (2x + 10)° and (6x + 8)°.
bearhunter [10]

Answer:

smaller angle is 50.5 degrees

Step-by-step explanation:

supplementary angles when added together = 180 degrees

(2x + 10) + 6x + 8 = 180

combine like terms

8x + 18 = 180

move the 18 over by subtraction

8x = 162

divide by 8 to get x by itself

x = 20.25

so plug in to find smaller angle

2(20.25) + 10 = 50.5

6(20.25) + 8 = 129.5

The answer is:  " 10,047.5 " .
_______________________________
Explanation:
________________________________
Given:  " x⁴ + 44 + 3.5 " ;  and given:  "x = 50" ;

we can plug in "50" for "x" ; and solve:
________________________________________
       10⁴ + 44 + 3.5 ;

       =  10,000 + 44 + 3.5 ;

       =   10,047.5

Average national teachers salaries can be modeled using the equation y=9.25(1.06)^n , where y is the salary in thousands of doll
kiruha [24]
y=9.25(1.06)^{n}
Plug in n to find y.
n would be 50 because 2020-1970=50.

Use order of operations to solve.
y=9.25(1.06)^{50} \\ y=9.25(18.42) \\ y=170.39

Since y is the salary in thousands, multiply 170.39 by 1000.
170.39*1000=17039

A teacher can expect to have about $17,039 as a salary in the year 2020.
