Step-by-step explanation:
Start (A3)
x is equal to 141 because they are alternate interior angles.
A2. x is equal to 39 because they are corresponding angles.
B2. x would be supplementary to 41 because the angle that x supplements is corresponding to 41.
41 + x = 180 due to the linear pair postulate. Therefore, x = 139.
B1. x would be supplementary to 82 because they are consecutive exterior angles.
82 + x = 180 due to the linear pair postulate. Therefore, x = 98.
C1. x = 102 due to the vertical angles theorem.
C2. x would be supplementary to 130 because the angle that x supplements is equal to 130 (Alternate Exterior Angles).
130 + x = 180, x = 50.
D2. x = 74, corresponding angles.
D3. x = 83, corresponding angles.
D4. x = 95, corresponding
C4. x is supplementary to 18 because of the consecutive interior angles theorem.
x = 162

Answer:
b=9,a=12
Step-by-step explanation:
I solved by substitution:
b = 3/4a ---> plug this into the other equation
a + b = 21 is now a + 3/4a = 21
Reduce: 7/4a = 21
a = 12
Now solve for b:
b=3/4a is now b=3/4(12)
b=9

Mizuki here to help!
8 minutes longer will be the correct answer!
Step-by-step explanation:
First, let's find out how many minutes Gabriella played:
3:32 - 2:49 = 2:92 - 2:49 = 0:43
Check:
2:49 + 0:43 = 2:92 = 3:32
It's correct so...
43 - 35 = 8
Hope this helped!
Answer:
B) 2
Step-by-step explanation:
Given expression,
48 ÷ ((2 + 6) × 2) − 1
In simplification we follows the following order,
B = Bracket
O = Of
D = Division
M = Multiplication
A = Addition,
S = Subtraction,
Thus, steps of solving the given expression by following BODMAS are as follow,
Hence, OPTION B is correct.
The student that did more maths problems per minute is Diedra.
In order to determine which student did more maths problems per minute, the rate of each student has to be determined. Rate is the total questions solved divided by the time.
Rate = total questions / total time
Malcolm = 15 / 18 = 0.833 problems per minute
Diedra = 16/ 17 = 0.941 problems per minute
