Write 2 equations:
a +b = 39
and b = 1/2a + 6
Now replace b in the first equation with the second one:
a + 1/2a + 6 = 39
Combine like terms:
1 1/2a + 6 = 39
Subtract 6 from each side:
1 1/2a = 33
Divide both sides by 1 1/2:
a = 33 / 1 1/2 = 33 / 1.5
a = 22
Now replace a with 22 in the first equation and solve for b:
22 + b = 39
b = 39 -22
b = 17
The two numbers are 17 and 22.
Answer:
C
Step-by-step explanation:
the expression equals 0. 5-5 is 0...
1:10 or 100:1000 so the point is to just add one zero to each side and you'll get it right
0.4kg per week. so 0.4kg x 6 weeks is 2.4kgs
