Answer:

x = 3

Step-by-step explanation:

All the angles of a square are 90°

The diagonals bisect the angles , then

5x² = 45 ( divide both sides by 5 )

x² = 9 ( take the square root of both sides )

x = \sqrt{9} = 3

Flour costs $0.80 per pound and sugar costs $0.50 per pound. An order of flour and sugar weighs 15 pounds and costs $9.00. Make
LenaWriter [7]

Answer: x+y=15

0.80x+0.50y=9


Step-by-step explanation:

Let x be the amount of flour and y be the amount of sugar ordered.

Since, the order of flour and sugar weighs 15 pounds.

Therefore, x+y=15

Also, Flour costs $0.80 per pound and sugar costs $0.50 per pound.

The cost of ordered flour=$0.80x

The cost of ordered sugar=$0.50y

Now, the total cost of the order= 0.80x+0.50y=9

Hence, for the given situation the system of equations is:-

x+y=15

0.80x+0.50y=9

Interior and Exterior Triangle Angles
Morgarella [4.7K]

Answer:

∠ WXY = 20°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ XYZ is an exterior angle of the triangle, thus

10x - 5 = 3x + 17 + 3x + 2

10x - 5 = 6x + 19 ( subtract 6x from both sides )

4x - 5 = 19 ( add 5 to both sides )

4x = 24 ( divide both sides by 4 )

x = 6

Thus

∠ WXY = 3x + 2 = 3(6) + 2 = 18 + 2 = 20°
