Answer:
you have to make a pyramid.
Step-by-step explanation:
The easy part is isolating the absolute-value term:
5 + 7 |2<em>x</em> - 1| = -44
7 |2<em>x</em> - 1| = -49
|2<em>x</em> - 1| = -7
Remember that the absolute value function returns a positive number that you can think of as the "size" of that number, or the positive distance between that number and zero. If <em>x</em> is a positive number, its absolute value is the same number, |<em>x</em>| = <em>x</em>. But if <em>x</em> is negative, then the absolute value returns its negative, |<em>x</em>| = -<em>x</em>, which makes it positive. (If <em>x</em> = 0, you can use either result, since -0 is still 0.)
The important thing to take from this is that there are 2 cases to consider: is the expression in the absolute value positive, or is it negative?
• If 2<em>x</em> - 1 > 0, then |2<em>x</em> - 1| = 2<em>x</em> - 1. Then the equation becomes
2<em>x</em> - 1 = -7
2<em>x</em> = -6
<em>x</em> = -3
• If 2<em>x</em> - 1 < 0, then |2<em>x</em> - 1| = - (2<em>x</em> - 1) = 1 - 2<em>x</em>. Then
1 - 2<em>x</em> = -7
-2<em>x</em> = -8
<em>x</em> = 4
Answer:
136°
Step-by-step explanation:
Look at the attached paper for the steps.
The number of squares of whole pita bread Min will have to cut up is;
<u><em>21 squares of whole pita bread</em></u>
- Since the triangle is isosceles, and has base of 4 cm with 2 equal sides of 6 cm, it means the height is 5.7 cm.
- Thus, area of triangle is;
A = ¹/₂ × 4 × 5.7
A = 11.4 cm²
- She will cut 3 pita triangles for every guest. This means that;
Area for each guest = 3 × 11.4 = 33.2 cm²
- There are 250 guests and so the total needed for the 250 guests is;
Total area = 250 × 33.2
Total area of pita bread = 8300 cm²
- The bread comes in 20 cm sides of a square shape.
Area of square = 20 × 20 = 400 cm²
- Number of squares of whole pita bread she will have to cut = 8300/400
⇒ 20.75 ≈ 21 squares of whole pita bread
