Answer:
-45
Step-by-step explanation:
-50 + 2a represents the sum of the constant -50 and twice the value of the variable a.
If a = 2.5, then -50 + 2a has the value -50 + 2(2.5) = - 50 + 5 = -45.
This will give you many results. AP = PB by construction
C is a point made by making the compass points such that AC>AP and the compass points are not altered so that BC = AC
C when joined to P creates a perpendicular line. This is very important. You use it a lot.
The answer is x²-8x+13=0
Here is how:
[x-(4+√3)][x-(4-√3)]=0
expand and simplify:
x² -(4-√3)x - (4+√3) +(4+√3)(4-√3)=0
x²-8x+13=0
The percent of the 7th graders that are in favor of school uniforms is 42.857% which can be rounded as 42.9%.
The survey results show there are a total of 112 7th-grade students and from this total, the number of students that support school uniforms is 48.
Let's calculate the percentage 48 represents:
- x = 48 x 100 / 112
- x = 4800 / 112
- x = 42. 857
This means the percentage of 7th graders that support uniforms is 42.857% which can be rounded to
