103 or 135 I’m not really sure which one
No it is not the same because you can not reverse division problems the same way you can with multiplication.
5 1/4 / 3 1/2 is asking how many times 3 1/2 can go into 5 1/4. The answer to this would be 1.5
3 1/2 / 5 1/4 is asking how many times 5 1/4 can go into 3 1/2. The answer to this would be .667
Answer:
x=3 and y= -1
Step-by-step explanation:
Step 1: Solve2x+y=5 for y:
2x+y=5
2x+y+−2x=5+−2x(Add -2x to both sides)
y=−2x+5
Step 2: Substitute−2x+5foryin5x+3y=12:
5x+3y=12
5x+3(−2x+5)=12
−x+15=12(Simplify both sides of the equation)
−x+15+−15=12+−15(Add -15 to both sides)
(Divide both sides by -1)
x=3
Step 3: Substitute3forxiny=−2x+5:
y=−2x+5
y=(−2)(3)+5
y=−1(Simplify both sides of the equation)
Answer:
x=3 and y=−1
Answer:
B
Step-by-step explanation:
15 divided by 2.49 equals 0.166 (Approximately 17 cents/oz) whilst 20 divided by 3.32 equals 0.111 (Approximately 11 cents/oz).
Answer:
12
Step-by-step explanation:
We are given that the table shows a proportional relationship between x and y. This can be represented by the equation, y = mx. Where k is the constant of proportionality.
Using the first pair given, (4, 16), let's find k.
k = y/x = 16/4
k = 4
Substitute k = 4 into y = kx
We have,
y = 4x
To find the value that completes the y-column, plug in the value of x into y = 4x.
x is given as 3.
Thus:
y = 4(3)
y = 12
