The order of operations is:
Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction
So division comes first:


Now subtraction:
Answer:
Option B
Step-by-step explanation:
From the picture attached,
In ΔABC,
m∠B = m∠C = 75° [Isosceles triangles]
By applying triangle sum theorem,
m∠A + m∠B + mC = 180°
m∠A + 75° + 75° = 180°
m∠A = 180° - 150°
m∠A = 30°
In triangle PQR,
m∠P = m∠Q [Isosceles triangle]
By applying triangle sum theorem,
m∠P + m∠Q + m∠R = 180°
2(m∠P) + 30° = 180°
m∠P = 75°
m∠P = m∠Q = 75°
In ΔABC and ΔRPQ,
m∠B ≅ m∠Q [Given]
m∠C ≅ m∠R [Given]
Therefore, by AA property of similarity of two triangles, both the triangles will be similar.
ΔABC ~ ΔRPQ
Option B will be the answer.
The ordered pairs below represent a relation between x and y.(-3,-3), (-2,0), (-1,3), (0,6), (1,9), (2,12)Could this set of orde

The set of ordered pairs generate a linear function because all the points lie in the same line that is described by the equation y = 3x + 6. The equation is found by choosing any two ordered pair and constructing the y =mx+b equation form where m is the slobe and b is the y-intercept.
To find the box answer, you can divide y by x:

You can check every pair, bit I'm going to show you the first 2 as an example:

So 3/2 is the answer!
Answer:
x = 21
Step-by-step explanation:
4 - 7x +10 = 15 - 6x - 8
-7x + 14 = -6x -7
14 + 7 = -6x + 7x
21 = x or x=21
