Joe's dad is ordering pizza for Joe and his friends. Joe says that he wants 5/8 of a
stepan [7]

Answer:

First we need to turn the values into decimals

2

Step-by-step explanation:

5/8 =  0.625

1/2 = 0.50

1/4 = 0.25

Now add the decimal values up which would be 0.625 + 0.50 + 0.25 = 1.375

You can't have 1.375 of a pizza so joe's dad is going to order at the minimum 2 pizzas so that everyone can have their desired amount

The interior angles formed by the sides of a quadrilateral have measures that some to 360°
Molodets [167]

Answer:

Value of x is 34

Step-by-step explanation:

The figure is a quadrilateral;

Angles given are; 2x°, 88°,108° and (3x - 6)°

We already know that the interior angles of a quadrilateral add up to 360°

Therefore, to get the value of x;

2x° + 88° + 108° + (3x - 6)° = 360

5x° + 190° = 360°

5x° = 170°

 x = 34°

Thus, the value of x is 34
