It is possible

Group 1 : 684 divided by 36 = 19$

Group 2 : 456 divided by 24 = 19$

Therefore, both groups 1 and 2 charge $19 for each ticket

Find y<br>Solve the simultaneous <br>equations<br><br><br>3x + 2y = 27 3x - Y = 9<br>

lutik1710 [3]

Answer:

$y = 6$

Step-by-step explanation:

To find $y$ , we need to eliminate $x$ in this system of equations:

$3\cdot x + 2\cdot y = 27$ (1)

$3\cdot x - y = 9$ (2)

From (1) and (2):

$x = \frac{27-2\cdot y}{3}$

$x = \frac{9+y}{3}$

Then, we equalize both expressions and solve for $y$ :

$\frac{27-2\cdot y}{3} = \frac{9+y}{3}$

$27-2\cdot y = 9 + y$

$3\cdot y = 18$

$y = 6$

Slope -3/7 and goes thru (9,-11)

goblinko [34]

The equation of line is ,

$\begin{gathered} (y-(-11))=\frac{-3}{7}(x-9) \\ y+11=\frac{-3}{7}x+\frac{27}{7} \\ y=\frac{-3}{7}x+\frac{27}{7}-11 \\ y=\frac{-3}{7}x-\frac{50}{7} \end{gathered}$

A salesman used three types of order forms: A, B, C. He used 40 of Form A. Of Form B he used four times as many as Form A plus 1

mixas84 [53]

Answer:

The correct option is A. 440

Step-by-step explanation:

Let a, b and c represents the number of orders from forms A, B and C,

According to the question,

$a = 40$ ,

$b = 4a + \frac{1}{2}c$

$c = a + \frac{1}{2}c$

From these equations we get,

$b = 160 + \frac{1}{2}c----(1)$

$c = 40 + \frac{1}{2}b---(2)$

Substitute the value of b from (1) to (2),

$c = 40 + \frac{1}{2}(160 + \frac{1}{2}c)$

$c = 40 + 80 + \frac{1}{4}c$

$c-\frac{1}{4}c = 120$

$\frac{4c-c}{4}=120$

$\frac{3c}{4}=120$

$c=\frac{480}{3}=160$

From (1),

$b = 160 + \frac{1}{2}(160)=160 + 80 = 240$

$\because a + b + c = 40 + 240 + 160 = 440$

Hence, he used 440 forms total,

i.e. OPTION A is correct.
