12 = r - (34 - 2)
subtract he 2 from 34
12 = r - (32)
add 32 to each side
r = 44
Check:
12 = 44 - (34 - 2)
12 = 44 - 32
12 = 12 :)
Given:
m∠ABC = 118°
m∠DAC = (9x - 33)°
m∠CAB = (2x + 7)°
To find:
The value of x.
Solution:
Sum of the adjacent angles in a parallelogram = 180°
m∠ABC + m∠CAB + m∠DAC = 180°
118° + 9x° - 33° + 2x° + 7° = 180°
92° + 11x° = 180°
Subtract 92° from both sides.
92° + 11x° - 92° = 180° - 92°
11x° = 88°
Divide by 11° on both sides.
x = 8
The value of x is 8.
14 times 17 is 238.
I will draw an area model and add it to my answer.
Hope this helps!!!
1st digit - 0-9 = 10 numbers
2nd digit = 9 numbers
3rd digit = 8 numbers
4th digit = 7 numbers
5th digit = 6 numbers
10 * 9 * 8 * 7 * 6 = 30,240 zip codes
