Answer:
37/24
Step-by-step explanation:
Since the denomenators must be consistent, both 8 and 12 have the common factor of 24.
the denominator of 8 must be multiplied by 3 to get to 24, but to multiply the denominator you must multiply the numerator by 3 which gives you
15/24
the denominator of 12 must be multiplied by 2 to get 24, so you must multiply 11 by 2 as well to get
22/24
add them together to get 37/24
Answer:
option 4
Step-by-step explanation:


Answer:
x = 348
Step-by-step explanation:
The measure of angle ABD is (0.15x+65) and the measure of angle CBD is(0.1x+28) . Find the value of x.
0.15x + 65 + 0.1x + 28 = 180
0.25x + 93 = 180
0.25x = 180 - 93
0.25x = 87
x = 87/0.25
x = 348
