20.50+36.21=56.57
Twice can be said as x2 so
20.50 x2=41
Leaving 56.57 and 41
56.67+41=91.67
Answer:
Step-by-step explanation:
p/q = 3(p + q) - 12
The quotient of p and q: p/q quotient means division
is means =
3(p + q) is three times the sum of p and q
3(p + q) - 12 twelve less than three times the sum of p + q
Answer:
x=2/5 y−2
Step-by-step explanation:
Answer: Phone C
Using quick mental math, we can do 8% of 10 to get 0.8, which is close to the value of 0.0845*10. Also fairly quick is moving the decimal point over 1 spot to the right and we go from 0.0845 to 0.845 and that rounds to 0.8 when rounding to one decimal place. Recall that 8.45% = (8.45/100) = 0.0845
If you want to compute out the four results with a calculator, then it would look like this:
0.0845*20 = 1.69
0.0845*25 = 2.1125
0.0845*10 = 0.845
0.0845*18 = 1.521
and this shows that no other result (but choice C) is close to 0.8
So that's why the answer is choice C
