Answer:
A = 1.5x + 1400
Step-by-step explanation:
Let us represent
The number of Adults = x
The number is children = y
The total amount of money raised = A
We are told in the question that:
A pancake breakfast fundraiser served 400 people and charged $5 for adults and $3.50 for children.
Hence:
x + y = 400.... Equation 1
y = 400 - x
Hence:
A = $5 × x + $3.50 × y
A = 5x + 3.50y
Where y = 400 - x
A = 5x + 3.50(400 - x)
A = 5x + 1400 - 3.50x
A = 1.5x + 1400
The equation for how much money was raised is given as:
A = 1.5x + 1400
There is a theorem in Geometry stating that the square of the tangent segment (ST) is equal to the product of the external secant segment (TR) and the whole secant segment (TQ).
SQ x SQ = TR x TQ
SQ squared = 7 x 30
SQ squared = 210
SQ =
BAD=BCD(base angle ,isosceles triangle)
ABD=CBD(given)
BAD+BCD+ABC=180(angle sum of triangle)
36+36+ABC=180
ABC=108
ABC=ABD+CBD
CBD=108/2
=54
therefore
x=54
Are you going to put the problems so people can help you
The answer is yes, every 5 dollars there is an extra 0.35$ tax so it’s a straight line which means that it is proportional
