Aday=24 hours
58days=24 times 58=1392 hours
60min=1hr
30min=1/2hr=0.5hr
total is
1392+15+0.5=
1407.5hours
Y = 1/6x + 4....the slope here is 1/6. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign.
So the slope of a perpendicular line will be -6/1 or just -6...see how I flipped the slope and changed the sign.
Answer:
commercial = 9
movie = 5
Step-by-step explanation:
Step one:
let the number of commercials be x and movies be y
so
40x+130y=1010-------------1
since there are a total of 14 commercials and movies combined
x+y=14--------------2
Hence the systems of equation is
40x+130y=1010------1
x+y=14-------------------2
Step two:
from equation 2
x=14-y
substui]te the value of x in equation 1
40(14-y)+130y=1010
560-40y+130y=1010
collect like terms
130y-40y=1010-560
90y=450
divide both sides by 90
y=450/90
y=5
movies is 90
put y=5 in equation 2
x+5=14
x=14-5
x= 9
commercial is 9 in numbers
and movie is 5
Answer:
Step-by-step explanation:
y= 40x + 50
y= 35x + 100
y= 40x + 50 = 35x + 100
40x - 35x = 100 - 50
5x = 50
x = 50/5
x = 10
y = 40 * 10 + 50 = 450
so the first answer is the correct one
