Answer:
76
Step-by-step explanation:
let the number be x
Then 16 + x/-4 = -3, so
x/-4 = -16-3 = -19 (add -16 on both sides)
x = -4*-19 = 76 (multiply by -4 on both sides)
The following table shows a proportional relationship between x and y.
x y
2 9
5 22.5
8 36
Write an equation to describe the relationship between x and y.
Answer:
Assume x is directly proportional to y :
[tex]y \: \alpha \: x \\ y = kx[/tex]
when y is 9, x is 2:
substitute to find value of k :
[tex]9 = (k \times 2) \\ k = \frac{9}{2} [/tex]
Therefore, equation is:
[tex]{ \boxed{ \boxed{2y = 9 x}}}[/tex]

The Sandhill School carnival sold $44 worth of advance tickets. The carnival organizers will also sell tickets at the door for $4 each. If 67 people buy tickets at the door, what will the total ticket sales amount to? Write and solve an equation to find the answer
Answer:
Below,...
Step-by-step explanation:
$44 + ($4*67) = Total_num_of_money
$4*67 = $268
$268 + $44 = $312
Chow,...!
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The total ticket sales.
= Total sales at the door + Total sales of advance tickets
= $268 + $44
The total ticket sales amount to $312.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
3x + 4 is an equation.
We have,
Total amount sold for advance tickets = $44
The number of tickets sold at the door = 67
Cost of the tickets sold at the door = $4
The total amount sold at the door.
= 67 x $4
= $268
Now,
The total ticket sales.
= Total sales at the door + Total sales of advance tickets
= $268 + $44
= $312
Thus,
The total ticket sales.
= Total sales at the door + Total sales of advance tickets
The total ticket sales amount to $312.

angle 3 and angle 4 are supplementary. m<3=7x-3 and m<4=2x+12. Find the measure of each angle
Step-by-step explanation:
Sum of supplementary angle = 180⁰
2x + 12 + 7x - 3 = 180
9x + 9 = 180
9x = 180 - 7
9x = 171
x = 171/9
x = 19
m<3 = 7(19) - 3 = 133 - 3 = 130⁰
m<4 = 2(19) + 12 = 50⁰

The equation of the line that is parallel to the line 5x + 2y = 12 and passes through the point (-2, 4) is y = [tex]-\frac{5}{x} x-1[/tex]
Parallel lines
Parallel lines have the same slope. Therefore, using slope intercept form.
y = mx + b
m = slope
b = y-intercept
Therefore,
5x + 2y = 12
2y = -5x + 12
[tex]y = -\frac{5}{2} x+12[/tex]
The slope of the line is [tex]-\frac{5}{2}[/tex]
Base on parallelism, for the line that passes through (-2, 4)
