Step-by-step explanation:
X = 24 *(* represents degrees as I’m on mobile)
A straight line is 180*.
The 156* angle and the x* angle make up a straight line, so 156*+x*=180* Subtract 156 from both sides to get x=24*
Answer:

Step-by-step explanation:
We are given the expression

We must multiply each term to each other term. Then we can combine all of the like terms

It becomes 7/40. To get it, you have to put 1/8 times 5/7. Then, flip the second fraction, (5/7), so that it becomes 7/5. Multiply 1/8 and 7/5, to get 7/40. You call this "reciprocal".
Lets say x is quantity
65%x+25%(600-x)=45%of 600
.65x+.25(600-x)=.45*600
.65x+150-0.25x=270
0.4x=120
x=300ml
