Answer:
part a:60 part b:9
Step-by-step explanation:
part a:
5,10,15,20,25,30,35,40,45,50,55,60,65
12,24,36,48,60
60 is the lowest number that's common in both
part b:
72=2×2×2×3×3×8
81=3×3×3×3
group the common ones so 2 pairs of 3 and 3's cancel out .
so 3 times 3 is 9
i dont know part c =(
The given equation is:
ax + by = 12
We are given that the two points (6,0) and (3,2) belong to this line. This means that these two points satisfy the equation of the line.
Therefore, to get the value of a and b, we will substitute with the given points in the equation and solve the resulting equations for a and b as follows:
For the point (6,0):
ax + by = 12
a(6) + b(0) = 12
6a = 12
a = 12/6 = 2
For point (3,2):
ax + by = 12
(2)(3) + b(2) = 12
6 + 2b = 12
2b = 12-6 = 6
b = 3
Based on the above calculations:
a = 2 and b = 3, therefore, the equation is:
2x + 3y = 12
Answer:
$29.7
Step-by-step explanation:
10 percent of 27 is 2.7 then you add 27 and 2.7 and you get 29.7
Follow the order of operation (PEMDAS) giving you 31
