When the second number is divided by the first, the result is ...
First table
9/3 = 3
12/4 = 3
20/5 = 4 . . . . result is not consistent. NOT a proportional relationship
Second table
25/20 = 1.25
30/24 = 1.25
40/32 = 1.25 . . . . result is consistent. A PROPORTIONAL RELATIONSHIP
Third table
12/4 = 3
15/5 = 3
24/6 = 4 . . . . result is not consistent. NOT a proportional relationship
Fourth table
4/3 ≈ 1.33
9/6 = 1.5
16/12 ≈ 1.33 . . . . result is not consistent. NOT a proportional relationship
The student who said 302 is a greater number is correct because since it has a 0 it brings the number into the hundreds while 32 is a lesser value . another example would be to make 32 you would need 3 ten blocks and 2 ones blocks and to make 302 would need 3 hundreds blocks and 2 ones blocks
if 7/2 = x/81
then you cross multiply and get
2x = 567 then divide by 2 and you get
283.5 and that's your answer
Answer:
Hsu makes $35,950.50 and Alkena makes $48,418.50
Step-by-step explanation:
Create a system of equations, where h is the amount Hsu makes and a is the amount Alkena makes:
a + h = 84,369
a = h + 12,468
Solve by substitution by plugging in h + 12,468 as a:
h + 12,468 + h = 84,369
2h + 12,468 = 84,369
2h = 71,901
h = 35,950.50
Plug this into the equation, a = h + 12,468 , to solve for a
a = 35,950.50 + 12,468
a = 48,418.50
So, Hsu makes $35,950.50 and Alkena makes $48,418.50
Recognize the differnce of 2 perfect squares
a²-b²=(a-b)(a+b)
so
Answer:
-5.5
Step-by-step explanation:
divide both sides by y which deleted y on the right side. then the left side turns into y instead of y squared. then you have y equals -5.5
