Ted needs an average of at least 70 on his three history test he has scored already 85 and 60 on two test what is the minimum gr
PilotLPTM [1.2K]
So average=(total of scores)/(number of tests)
needs at least average of 70
at least is represented as greater than or equal to or the sign (<u>></u>)
70<u>></u>(total)/(number oftests)

since we have 3 tests, we have to have 3 scores so
70<u>></u>(x+y+z)/3
he scored 85 and 60
70<u>></u>(x+85+60)/3 (doesn't matter which to subsitute)
70<u>></u>(x+145)/3
multiply obht sides by 3
210<u>></u>x+145
subtract 145 from both sides
65<u>></u>x

Find the other endpoint given endpoint (-10,7) midpoint (6,2)
Makovka662 [10]

Answer:

(22;-3)

Step-by-step explanation:

if to calculate the coordinates of the given midpoint it needed to use:

x_{midpoint}=\frac{x_{endpoint1}+x_{endpoint2}}{2};

y_{midpoint}=\frac{y_{endpoint1}+y_{endpoint2}}{2};

then to calculate the coordinates of endpoint2, it needed to perform the substitution:

\frac{-10+x_{endpoint2}}{2}=6,

2=\frac{7+y_{endpoint2}}{2},

finally:

x_{endpoint2}=22;

y_{endpoint2}=-3.
