Hello :
93-84 =84-75 = 75-66 = 66-57 = 9 ...( common diference of arithmetic <span>sequence )
Un = U1 + (n-1)d d= 9 and U1 = 57 n = 250
U250 = 57 +249(9) = 2298</span>
A rock climber's elevation above sea level changed −82 1/2 feet in 2 1/4 minutes as she descended.
so the the climber's average change in elevation per minute was:
x = -82 1/2 / 2 1/4x = (-165/2) / (9/4)x = (-165/2) x (4/9)x = -18 feet per minute is his change in elevation
The answer to the question
Answer:
47
Step-by-step explanation:
In the first step, inside the brackets I took the LCM and then in second step I subtracted 3 from 11 which gave result of8÷8=1 then 1 is multiplied to 2 which becomes 49-2 and 47 is the result
