Answer: 66 because you are adding 2 then 4 then 6 then 8 then 10 then 12 therefore 17+10= 27, and 27+12= 39 and 39+27 equals 66
Answer:
18 dollars
Step-by-step explanation:
We can write a proportion to solve
2 tacos 6 tacos
--------------- = ------------
6 dollars x dollars
Using cross products
2*x = 6*6
2x = 36
Divide by 2
2x/2 36/2
x = 18
18 dollars

96kg
Step-by-step explanation:
3/4 of 64 is 48
2 × 48 = 96kg
Answer: 37/12
Step-by-step explanation:
11/12+2 1/6=
2+11/12+(1*2)/(6*2)=
2*12/12+11/12+2/12=
24/12+13/12=37/12
The real part of the result is the product of the real parts of the factors and the product of the imaginary parts:
a = 15*6 - (-4)(-3) = 90 -12 = 78
_____
You can treat this the same as any other product of binomials except that i² = -1.
... (15 -4i)(6 -3i) = 15(6 -3i) -4i(6 -3i) = 15·6 -15·3i -4·6i +4·3i²
... = 90 -45i -24i +12i² = (90 -12) -69i = 78 -69i
