$8 + $7 + $13 + 15 = $43
$x - $43 = $12
x = $55
i am a mathematics teacher. if anything to ask please pm me
So 12 mins to 600 feet
35 mins=1900 feet
find the slope which is change in top over change in bottom (aka slope) so to find do
(y1-y2)/(x1-x2)
we want, per minute, so put the time as x1 and x2
x1=12
y1=600
x2=35
y2=1900
subsitutte
(600-1900)/(12-35)=-1300/-23=56.5 per minute
the answe ris 56.5 feet per minute or the last answer
Answer:
2 x 2 x 2 x 3, so its E
Step-by-step explanation:
Solve for y
minus 10x from both sides
5y<-10x+15
divide both sides by 5
y<-2x+3
ANSWER
X < 9
Solve
2x < - x + 20 + 7
2x < - x + 27 change the signs
2x + x < 27 add the like terms
3x < 27 divide by 3
x < 9
