A total of 150 tickets were sold for the annual concert. Student tickets were $4 and non-students $8. If the total revenue was $840, how many tickets of each type were sold ?
Answer:
x = 90
y = 60
Step-by-step explanation:
Let x = student
Let y = non-student
x + y = 150
4x + 8y = 840 <—— Use elimination/addition ethos for both equations
8 (x + y = 150)
-1 (4x + 8y = 840) <—— Let’s eliminate y
8x + 8y = 1200
+ -4x - 8y = -840
—————————————
4x = 360
x = 90
x + y = 150 <— substitute for x from above
90 + y = 150
- 90 = - 90 <— subtract from both sides
y = 60
What is the solution?
Answer:
(1,-1)
Step-by-step explanation:
the solution is where the two lines meet up at and they meet up at (1,-1)
x + 3y = 2
-x + 2y = 3

Chord AC intersects chord BD at point P in circle Z. AP=12 m DP=5 m PC=6 m What is BP?
Answer:
BP = 14.4
Step-by-step explanation:
Given 2 chords intersecting inside a circle, then
The products of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is
BP × DP = AP × PC , that is
BP × 5 = 12 × 6
5BP = 72 ( divide both sides by 5 )
BP = 14.4

Step-by-step explanation:
The top of the jack is 10 inches from ground.
What is parallelogram?A parallelogram is a two-pair quadrilateral with parallel sides. A parallelogram has opposite sides that are the same length and have opposite angles that are the same size. Additionally, the interior angles on the same transversal side are supplemental. 360 degrees are the sum of all the interior angles.
A parallelepiped is a three-dimensional shape with parallelogram-shaped faces.
Given Jack is in shape of parallelogram,
height of crank of jack from ground = 5 inches
to find the distance from ground to top of jack
since crank is at centre of jack and bottom to top of jack makes the diagonal of parallelogram,
distance from crank to top of jack is 5 inches,
because The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal.
total length from ground is 5 + 5 = 10 inches
Hence length from ground to top of jack is 10 inches because diagonals bisect each other.

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
