I believe x would equal to 30.
Since 6 * 3 =18, 10 * 3 = 30.
What you do to one side, you must do to the other.
Hope I helped!
Set up two equations:
Greg = 330 + 75X
Heather = 660 + 45x
Set them to equal and solve for x:
330 + 75x = 660 + 45x
Subtract 330 from both sides:
75x = 330 + 45x
Subtract 45x from both sides:
30x = 330
Divide both sides by 30:
x = 330 / 30
X = 11
11 months they will have the same amount saved.
a) situation you’re familiar with where one quantity changes constantly in relation to another quantity is Velocity = Distance/Time
b) the velocity is in direct proportion to distance and inverse relation to time.
c) The graph shown by velocity- time is a straight line graph.
<h3>what is algebra?</h3>
Algebra is a branch of mathematics that deals with symbols or variables and uses arithmetic operations (+, –, ×, ÷) to find the unknown quantities represented by these variables.
There is a equation we are familiar with , the equation of motion
Velocity = Distance/Time
Here, velocity increases or decreases if the distance also increases or decreases. But if time increases velocity decreases.
So, the velocity is in direct proportion to distance and inverse relation to time.
The graph shown by velocity- time is a straight line graph.

Answer: 17 inches</h3>
===============================
Rule: All four sides of a rhombus are the same length
So AB = BC
Use this to solve for x
AB = BC
3x+2 = x+12
3x-x = 12-2
2x = 10
x = 5
If x = 5, then
AB = 3*x+2 = 3*5+2 = 15+2 = 17
and
BC = x+12 = 5+12 = 17
Both sides are 17 as expected, so the proper x value is confirmed.
So DC is also 17 since AB = DC
