Answer:
8z-2.5y
Step-by-step explanation:
5+3=8
1/2+ 2= 2.5
The 5 is in the hundreds place so the value of the 5 is 500.
Subtracting 1 from 5 the number becomes 4 ( 5-1 = 4) which would mean the new value would be 400
The answer is b. 400
Sin^2 + cos^2 =1
COS t= .9897
Since tan=sin/cos < 0 so cos = -.9897
Tan = sin/cos = (1/7)/(-.9897)= -.1443
