2x = 4y
x = (4y)/2
x = 2y

8x = - 2y - 10
8(2y) = -2y - 10
16y + 2y = -10
18 y = -10
y = -10/18
y = -5/9

So, how x = 2y
x = 2 (-5/9)
x = -10/9

deff fn [24]

Answer:

4.5 miles per hour

Step-by-step explanation:

Selma uses a jogging trail that runs through a park near her home. The trail is a loop that is 3/4 of a mile long. On Monday, Selma ran the loop in 1/6 of an hour. What is Selma's unit rate in miles per hour for Monday's run?

Distance = 3/4 of a mile

Time taken on Monday = 1/6 of an hour.

What is Selma's unit rate in miles per hour for Monday's run?

Unit rate in miles per hour for Monday's run = distance ÷ time taken

= 3/4 ÷ 1/6

= 3/4 × 6/1

= (3 * 6) / (4 * 1)

= 18/4

= 4.5 miles per hour

Unit rate in miles per hour for Monday's run = 4.5 miles per hour

Which set does 7 belong too
Zina [86]

The number that 7 belongs to is a rational number.

<h3>What is a rational number?</h3>

Rational numbers are terminating decimals but irrational numbers are non-terminating and non-recurring.

Therefore, the number that 7 belongs to is a rational number.
