Answer:
-6000
Step-by-step explanation:
20{5[100-3(25+35)+20]} open the parenthesis
20{5[100-180+20]} do the addition and subtraction in the square brackets
20{5[-60]} open the square brackets
20{-300} open curly brackets
-6000
Answer:
The value of x is 120°.
Step-by-step explanation:
Given that 3 identical square form a triangle in between. So this triangle has an identical angle so it is :
180° ÷ 3 = 60°
Next, this squares have an identical angle which is :
360° ÷ 4 = 90°
As you look carefully at the diagram, in the edges of triangle, there is a complete circle which is 360°. SO in order to find x, you have to substract 90° and 60° from 360° :
x + 90° + 60° = 360°
x = 360° - 90° - 90° - 60°
x = 120°
Answer:
240 students
Step-by-step explanation:
Grade 7 : Grade 8 = 5 : 3
Number of seventh grade students = 5x
Number of Eighth grade students = 3x
3x = 90
x = 90÷3
x = 30
Total students = 5x + 3x = 8x = 8 * 30 = 240
They had the same quotient because both of those equations are equal
