Answer:
see below
Step-by-step explanation:
22% is close to 20 % = .2 in decimal form
78 is close to 80
.2 * 80 = 16
If the answer is close to 16 then it is reasonable
22% of 78 = 17.16
Answer:
(a)x= y+14
(b)x=34, y=20
Step-by-step explanation:
Let the number of tickets sold by your friend = y
Let the number of tickets sold by you=x
You sell 14 more tickets than your friend sells.
Number of tickets sold by you, x= y+14
(a) The system of linear equations that represents this situation is: x= y+14
(b)Together, you and your friend sell a total of 58 tickets.
x+y=54
Since x= y+14
(y+14)+y=54
2y+14=54
Subtract 14 from both sides
2y+14-14=54-14
2y=40
Divide both sides by 2
y=20
Recall, x= y+14
x=20+14=34
You sell 34 tickets and your friend sells 20 tickets.
An equation of line with a slope of 1/3 and containing the point (-4,7) is
y = 1/3 x + 25/7
In this question, we have been given
slope (m) = 1/3
and a point (-4, 7)
We need to find an equation of a line with a slope of 1/3 and containing the point (-4,7)
Using the formula for the slope-point form of equation of line,
y - y1 = m(x - x1)
y - 7 = 1/3(x + 4)
y - 7 = (1/3)x + 4/3
y = (1/3)x + 4/3 + 7
y = 1/3 x + 25/7
Therefore, an equation of line with a slope of 1/3 and containing the point (-4,7) is y = 1/3 x + 25/7
