Answer:
(B) 4y = 3x-2
Step-by-step explanation:
Divide by the coefficient of y to see the slope. It will be the resulting coefficient of x. Only choices B and D match requirements.
Check to see which equation is satisfied by the given point:
B: 4(1) = 3(2) -2 . . . . true
D: 4(1) = 3(2) +5 . . . .false
The appropriate equation is ...
4y = 3x-2
To find the sales price of the DVD, you would multiply the price and sale percent to get the sale price.
You would need to turn 20% into a decimal to multiply it with 9, so you would move the decimal place two times to the left: From 20. to→ .20
In this case: 9 × .20 = 1.8
Then you would subract the sub price by the sales price
9 - 1.8 = 7.2
The sales price of the DVD would be $7.20
This question wants you to find a common denominator for the fractions.
This means finding the LCM, least common multiple, for 21 and 9.
This can be done by listing the multiples for each number until they meet at a common one.
9:
9
18
27
36
45
54
63
21:
21
42
63
This means the LCM of 21 and 9 is 63.
So the lowest possible common denominator is 63.
21 • 3 = 63
So you have to multiply the numerator of 2/21 by 3 as well.
2 • 3 = 6
2/21 = 6/63
Now do the same for 1/9.
9 • 7 = 63
Multiply the numerator, 1, by 7.
1 • 7 = 7
1/9 = 7/63
So in the first blanks, you would put 6/63 for what 2/21 is equal to and 7/63 for what 1/9 is equal to.
7/63 is greater than 6/63.
7/63 > 6/63
That means 1/9 > 2/21
So 2/21 < 1/9 is the answer to the last blank.
Hope this helps!
