Answer:
-20
Step-by-step explanation:
i think
x:14 = 7:8
x:14 = x/14
7:8 = 7/8
x/14 = 7/8
Multiply the numerator of the 1st ratio with the denominator of the 2nd.
And multiply the numerator of the 2nd ratio with the denominator of the 1st.
Doing so, we get -
x * 8 = 7 * 14
So, 8x = 7 * 14
8x = 98
We divide 98 by 8 (transposition method)
x = 98/8
Therefore, x = 12.25
The answer is (B) because B and D are the only ones that the GCF is 4 and 32+40 is not 76 thus making it B. Hope this Helps.
