Answer:

Step-by-step explanation:

The ratios of the two shortest sides are different:

3/2 ≠ 5/4

so the quadrilaterals cannot be similar.

Total of 380 tickets were sold for the school play. they were either adult tickets or student tickets. there were 70 fewer stude

Bogdan [553]

Let the amount of adult tickets sold be x

Since the total of 380 tickets sold consists of the amount of adult tickets and the amount of children tickets that are 70 fewer:

x + (x - 70) = 380
2x - 70 =380
2x = 450
x = 225

Therefore, the amount of adult tickets sold is 225

How do you solve this type of problem, what would be the procedure? Assume PQRS is a parallelogram, if PQ=x2−10 and SR=3x , find

NeTakaya

Answer:

$x = 5$

Step-by-step explanation:

Given

Shape: Parallelogram PQRS

$PQ = x^2 - 10$

$SR = 3x$

Required

Find all possible values of x

Every parallelogram have parallel and equal opposite sides;

From the given parameters, one can easily deduce that PQ and SR are opposite sides;

This implies that

$PQ = SR$

Substitute values of PQ and SR

$x^2 - 10 = 3x$

Subtract 3x from both sides

$x^2 - 10 -3x = 3x - 3x$

$x^2 - 10 -3x = 0$

Rearrange

$x^2 -3x- 10 = 0$

Now, we have a quadratic equation;

Expand the above expression

$x^2 +2x-5x- 10 = 0$

Factorize

$x(x+2)-5(x+2) = 0$

$(x-5)(x+2) = 0$

$x - 5 = 0$ or $x + 2 = 0$

Solve for x in both cases

$x = 5$ or $x = -2$

But x can't be negative;

So, the possible value of x is

$x = 5$

jerome tries to find the value of the expression 3-6+5 by first applying the communtative property. he rewrites the expression a

slega [8]

The commutative property is a property of addition, not of subtraction. It can work in a subtraction problem if you keep the sign with the number, so you're adding positive and negative numbers.

3 - 6 + 5

= (3) + (-6) + (5)

= (3) + (5) + (-6)

= 3 + 5 - 6
