Answer: yes

Here, we want to decide if 15 is a solution for the equation 4b - 20 = 40. We can do this by simply plugging in 15 for b. If the statement holds true when 15 is plugged in for b, then 15 is a solution.

Plugging in 15 for b, we have 4(15) - 20 = 40.

4(15) is equal to 60.

So we have 60 - 20 = 40 or 40 = 40.

Since the statement holds true, yes,

15 is a solution for the equation.

how do the values compare ? order the values from greatest to least 3/4 , - 1 3/4 , -1 1/4, - 2 1/4, 2 1/4, 1 1/4

natali 33 [55]

Answer:

The order of the values from greatest to least are as

$\frac{21}{4} > \frac{11}{4} > \frac{3}{4} > \frac{-11}{4} > \frac{-13}{4} > \frac{-21}{4}$

Step-by-step explanation:

Negative number goes on decreasing in this way as -1,-2,-3,-4,-5... and so on.

So,-11 > -13 > -21

Here the denominator is same and the numerator is in decreasing order i.e greatest to the least that is 21 > 11 > 3 > -11 > -13 >-21 .Therefore, the order is

$\frac{21}{4} > \frac{11}{4} > \frac{3}{4} > \frac{-11}{4} > \frac{-13}{4} > \frac{-21}{4}$

Answer:

y=3x

Step-by-step explanation:

If y is the total distance from the shore and it increases by 3 miles every hour, then by plugging in the amount of hours that have passed into x we will find the distance they have traveled. For example, if they have been out for 5 hours then you would do y=3(5) which would be 15 miles from the shore.

Hope this helps :)
