On a consert the tickets cost 3$ for children, and 5$ for adults. The combined income is 360$ and 84 tickets were sold. How many

klio [65]

Let x equal the # of child tickets

Let y equal the # of adult tickets

x + y = 84

3x + 5y = 360

Solve and state the answer. Use the substitution method to solve this system. Solve the first equation for x.

x + y = 84

x = 84 - y

Now substitute the resulting expression into the other equation and solve for y.

3( 84 - y ) + 5y = 360

252 - 3y + 5y = 360

Combine like terms

252 + 2y = 360

Subtract 252 from both sides

2y = 108

Divide by 2 on both sides

y = 54

Substitute the value of y into the equation that we solved for x, x = 84 - y

x = 84 - 54

x = 30

Therefore the answer should be, 30 childrens tickets sold and 54 adult tickets sold.

2y +9 =x 9x- 8y=31 System of substitution

VLD [36.1K]

Answer:

x = -1

y = -5

Step-by-step explanation:

9(2y+9) - 8y = 31

18y + 81 - 8y = 31

10y + 81 = 31

10y = -50

y = -5

2(-5) + 9 = x

-10 + 9 = x

-1 = x

A number line goes from negative 5 to positive 5. Point D is at negative 4 and point E is at positive 5. A line is drawn from po

Directed numbers are numbers that have either a positive or negative sign, which can be shown on a number line. Therefore, point F is Fifteen-halves of line segment DE.

A number line is a system that can show the positions of positive or negative numbers. It has its ends ranging from negative infinity to positive infinity. Thus any directed number can be located on the line.

Directed numbers are numbers with either a negative or positive sign, which shows their direction with respect to the number line.

In the given question, the distance between points D and E is 9 units. So that dividing 9 units in the ratio of 5 to 6, we have;

$\frac{5}{6}$ x 9 = $\frac{45}{6}$

= $\frac{15}{2}$

Therefore, the location of point F, which partitions the directed line segment from d to E into a 5:6 ratio is $\frac{15}{2}$ . Thus the answer is Fifteen-halves.
