Answer:

C, E

Step-by-step explanation:

The unit rate represented by the point (x, y) is y/x. To find which rates are lower than 3/5, we can find the difference ...

... 3/5 - y/x

If that difference is positive, then the rate represented by the table is lower.

That difference is ...

... (3x -5y)/(5x)

Since we're only interested in the sign, we only need to compute the numerator value.

A. 3·3 -5·4 = -11 . . . . . the table has a higher rate

B. 3·5 -5·4 = -5 . . . . . the table has a higher rate

C. 3·31 -5·18 = 3 . . . . the table has a lower rate

D. 3·18 -5·11 = -1 . . . . the table has a higher rate

E. 3·12 -5·7 = 1 . . . . . the table has a lower rate

Choices C and E are appropriate.

Please help me this is urgent!

Gnesinka [82]

Answer:

D. 2 times the distance

Step-by-step explanation:

Practical Math advice: Word Problems usually are tricky so draw, write, and label all you know.

***We want to know how many times farther do the Knicks travel when they play the Los Angeles Lakers compared to the Miami Heat? ***

To do this, we just need to know the distance between the two and divide the bigger by the smaller (think if I told you distance from part A to B is 6 and the distance from part A to C is 3. And then ask you how many times farther the distance to C is from A than B. just divide 6/3 = 2)

1) Note the distance from Madison to Staples (2.8 × 103 miles) and Madison to American A. (1.4 × 103 miles).

We can associate Knicks with Madison, Los Angeles with Staples, and Miami Heat with American A.

2) Now divide 2.8 × 103/(1.4 × 103) = 2
