Riley's age = r
Riley's brother's age = r/4

If Riley was 11 five years ago, Riley is currently 11 + 5 years old, or 16 years old.

Now we just need to use r/4 to find Riley's brother's age:

16 /4 = 4

Riley's brother is 4 years old.

Hope this helps!

Order the numbers below least to greatest<br> Please help me
n200080 [17]

The given numbers ordered from least to greatest is:

{√7 , 2.8..., π, √17,  4.6}

<h3>How to order the numbers from least to greatest?</h3>

First, we need to write all the given numbers in decimal form so we can accurately compare them.

The numbers are:

{4.6, √7, π, 2.8..., √17}

Rewriting all of these in decimal form:

√7 = 2.64

π = 3.14159265....

√17 = 4.12

Then the numbers are:

{4.6, 2.64, 3.14159265....,  2.8..., 4.12}

Now is easier to order these numbers, ordering them from least to greatest we will get:

{2.64, 2.8..., 3.14159265...., 4.12, 4.6}

Now, using the original notation we get:

{√7 , 2.8..., π, √17,  4.6}

A mail courier charges a base fee of $6.95 plus $7.60 per package being delivered. If x represents the number of packages delive
castortr0y [4]
Since 7.6 is the cost per package, and x represents the number of packages, the expression 7.6x would represent the cost for the packages. Once we add the base fee, we get the equation:

y = 7.6x + 6.95

Hope this helps.

Write an equation of the line containing the given point and parallel to the given line.
Dafna11 [192]

Answer:

y = 5/9x - 37/3

Step-by-step explanation:

5x - 9y = 8

-9y = -5x + 8

y = 5/9x - 8/9

  • When a line is parallel, the slope remains the same.

y = 5/9x + b

-9 = 5/9(6) + b

-9 = 10/3 + b

-37/3 = b
