Answer:
-10+15
Step-by-step explanation:
Pls Brainliest! ;) It would mean a lot! Also this is called integers addition on a line plot.
X=5 is the answer because
sqrt (3/10)
sqrt(3)/sqrt(10)
no sqrt in the denominator, so multiply by sqrt(10)/sqrt(1)
sqrt(3) sqrt(10)
-------------------
sqrt(10) sqrt(10)
sqrt(30)/10
Choice D
Answer:
32
Step-by-step explanation:
40 = 100%
how many are 80% ?
well, 80% = 80× 1%
1% = 100% / 100
so, in our case
80% = 80×40/100 = 8×4 = 32
as a shortcut you consider a percentage x as a ratio factor of x/100 you multiply the 100% number with.
in our case
80% = 40 × 80/100 = 32
You just finish the equation by adding 19 to 42 which is 61.
