John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. The pizza cost $12.50. They spend a total of $16.85. Write an equation to represent the problem. Find the cost of one large drink.
Answers
Answer:
Hm, okay.
Step-by-step explanation:
So, if the pizza cost $12.50, and the total money spent is $16.85, we must first subtract our money spent on pizza from the total amount spent.
$16.85 - $12.50 = $4.35
So, that means that John and his two friends spent $4.35 on 3 large drinks. But how do we figure out how much each individual drink cost?
We divide $4.35 by 3.
$4.35 / 3 = $1.45.
So, the amount of money spent on one large drink was $1.45.

The solution of the given linearequation 5x+10=10y is .
Two algebraic expressions separated by an equal symbol in between them and with the same value of the expression are called equations.
Example = 2x +4 = 12
here, 4 and 12 are constants and x is variable.
The value of y can be calculated as:
5x+10=10y
Since, the equation is divisible by 5,
So, the equation becomes,
x+2=2y
Divide both sides by 2, to get the value of y
Thus, the value of y in the given equation 5x+10=10y is .

P = 2x + 2y
48 = 2x + 2y
The area of the rectangle has the formula
A = xy
108 = xy
So,
x = 108/y
Substituting this to the first equation
48 = 2(108/y) + 2y
48y = 216 + 2y^2
2y^2 - 48y + 216 = 0
Solving the quadratic equation:
y = 18 or 6
Either of the two is the correct answer for y, the value of x would just be the other. So, the dimensions of the garden is
18 m x 6 m

The smaller triangle joining the midpoints of the bigger right angle triangle will also be a right angle triangle.
Midpoint Theorem-
According to this, the segment joining two sides of a triangle at the midpoints is half the length of the third side.
Applying this,
So, the hypotenuses of the bigger triangle will be,
Applying the mid point theorem, the hypotenuses of the smaller triangle will be,
Applying Pythagoras theorem in the smaller triangle, the leg will be
