x = y + 4 is already done so we will substitute that into the other equation!
3(y + 4) + y = 16
Distribute.
3y + 12 + y = 16
Add the terms.
4y + 12 = 16
Give y its own side.
4y = 4
Divide by 4.
y = 1
Substitute this back into one of the equations.
x = 1 + 4
x = 5
The point for these 2 equations is (5, 1)

The simplified expression is 40 + 25e
<h3><em><u>
Solution:</u></em></h3>
Given that, Riley’s parent got a cell phone plan that has a $40 monthly fee for the first phone
For each extra phone,
Phone service charge = $15
Text service charge = $10
<em><u>The expression that represents the total phone bill in dollars is given by:</u></em>
40 + 15e + 10e
Where "e" is the number of extra phones
We are asked to simplify the expression
Combine the like terms. Here like terms are 15e and 10e
Therefore, add 15e and 10e
Thus the simplified expression is 40 + 25e
HELLO!!!
If the diameter is 12, this means that the radius is half of that amount (6)
In order to find area of a circle, you must solve pi x r^2 pi is 3.16 and the radius is 6. 6 ^2 is 36.
36x (pi) is 113.09 which should round off to 113.1 This means that area of the circle is 113.1 cm.
I Hope This Help & good luck.
Given:
Chang ran three times last week. The distances he ran (in kilometers) are 4, 8.36, 18.9.
To find:
The total distance Chang ran on these three days.
Solution:
It is given that the distances he ran (in kilometers) are 4, 8.36, 18.9.
We need to add these three distances to get the total distance Chang ran on these three days.
Therefore, the total distance Chang ran on these three days is 31.26 kilometers.
