For a school play, 739 tickets valued at $857 were sold. Some cost $1 and others cost a $1.50. How many $1 tickets were sold?

balu736 [363]

Answer:

503 $1 tickets sold.

Step-by-step explanation:

Use two equations

Let x = number of $1 tickets sold

Let y = number of $1.50 tickets sold

x + y = 739

1x + (1.5)y = 857

First equation ==> y = 739 - x

Plug this into the second equation

x + (1.5)(739 - x) = 857

x + 1108.5 - 1.5x = 857

- 0.5x = -251.5

x = 503

There were 503 $1 tickets sold.

To find the number of $1.50 tickets, just plug this value of x into either one of the equations.

(503) + y = 739 (739 - 503 = 236)

y = 236

There were 236 $1.50 tickets sold.

Write a expression for j less than 113

kiruha [24]

So you just need to use the crocodile signs < or >
As j is less than 113 we put j on the smaller side and 113 on the bigger side to make:
j<113

. A rowing club has 600 members. 60% of them are women. After 200 new members joined the club, the percentage of women was reduc

valkas [14]

Answer:

Step-by-step explanation:

Given:

Initial number of members = 600

Percentage of women = $60\%\ of\ 600=0.60\times 600=360$

Now, members added = 200

So, total number of members after addition = 600 + 200 = 800

Percentage of women out of 800 members = $50\%\ of\ 800=0.50\times 800 =400$

Increase in women = New number of women - Old number of women

Therefore, increase in women = 400 - 360 = 40

So, 40 women are there in the 200 new members that joined the club.

Answer:

see explanation

Step-by-step explanation:

(3)

Parallel lines have equal slopes

the equation of a line in sloipe- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = $\frac{1}{4}$ x + 5 ⇒ m = $\frac{1}{4}$

y = 4x + 5 ⇒ m = 4

y = - 4x + 5 ⇒ m = - 4

y = - 4x - 9 ⇒ m = - 4

the 3rd and 4th options have equal slopes and are parallel

(4)

given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$

y = $\frac{1}{6}$ x + 4 ⇒ m = $\frac{1}{6}$

y = - $\frac{1}{6}$ x + 5 ⇒ m = - $\frac{1}{6}$

y = $\frac{1}{6}$ x + 3 ⇒ m = $\frac{1}{6}$

y = 6x + 3 ⇒ m = 6

note that a slope of m = 6 , has a perpendicular slope of

$m_{perpendicular}$ = - $\frac{1}{6}$

the 2nd and 4th lines are perpendicular
