The answer is -7.6.
Start with the innermost grouping:
(-5.2)+(-3.8)-{(-1.2)-[(-0.5)-(-0.7)]}
Subtracting a negative is the same as adding a positive:
(-5.2)+(-3.8)-{(-1.2)-[(-0.5+0.7)]}
(-5.2)+(-3.8)-{(-1.2)-[0.2]}
Now start with the next inner grouping:
(-5.2)+(-3.8)-{-1.4}
Again, subtracting a negative is the same as adding a positive:
(-5.2)+(-3.8)+1.4
Add the first two together:
-9.0+1.4
Adding the last two, we get -7.6.
Answer:
E=x
or 110= x ( opposite angles of parallelogram are congurent)
E+D = 180 ( angles on st line)
110+D =180
D=70
D=F ( opposite angles of parallelogram are congurent)
so F=70
Answer:
Step-by-step explanation:
There are four important oceanic zones where plants and mammals survive in the ocean. The four significant zones are open ocean zone, intertidal zone, neritic zone, and benthic zone.There are four ocean zones. The sunlight zone, twilight zone, midnight zone, and abyssal zone.
We set up an equation: 5/?= 10/100
Cross multiply:
10*?= 5*100
⇒ ?= 5*100/10= 50
5 is 10% of 50~
