1) 2x-1 or x=1/2
2) 5a-16 or a=16/5
We know that
if sin A=cos B
then
angle A and angle B are complementary angles
so
A+B=90 degrees
in this problem
(x+34)+(2x+20)=90-------> 3x+54=90----> 3x=90-54-----> x=36/3----> x=12°
the answer is
the value of x is 12 degrees
It fell by 19%
Use 1173 as your total and then find the percent from 951 and subtract from 100 and that’s the percent that fell
<em>Answer:</em>
47/48
<em>Explanation:</em>
Since 5 7/8 is so close to 6, it is easier to work this problem by considering the difference.
The serving size is 1/6 of the total amount, so you want to find ...
... (5 7/8) × (1/6)
Following the observation above, we can compute it as ...
... (6 - 1/8) × (1/6) = (6/6) - (1/8)×(1/6)
... = 1 - 1/48
... = <em>47/48</em>
