<span>We simplify the equation to the form, which is simple to understand
<span>q+2/5=2q-11/7
Simplifying:
<span>q + 0.4=2q-11/7
Simplifying:
<span>q + 0.4=2q-1.57142857143
We move all terms containing q to the left and all other terms to the right.
<span>+1q-2q=-1.57142857143-0.4
We simplify left and right side of the equation.
<span>-1q=-1.97142857143
We divide both sides of the equation by -1 to get q.
<span>q=1.97142857143</span></span></span></span></span></span></span>
Answer:
Elizabeth had 30 stamps originally.
Step-by-step explanation:
Let,
x be the number of stamps Elizabeth have.
Number of stamps given to John = 1/6 of x = 
Remaining stamps = 
Stamps given to Peter = 1/5 of remainder = 
Number of stamps left = 20
Now,

Dividing both sides by 4

Hence,
Elizabeth had 30 stamps originally.

Answer:
a=3/5 or 0.6
Step-by-step explanation:
a-8/5-2/3a=-7/5
Step 1: Multiply both sides
15a-24-10a=-21
Step 2: Combine like terms
5a-24=-21
Step 3: Calculate and divide both sides by 5
5a=3
Solution:
a=3/5 or 0.6
As the name suggests, the slope-intercept form requires you to find the slope and the intercept. Slope-intercept form is y=mx+b
You can find slope by rise over run, or get two points and plug them into the following formula:

. However, if you see that x values increase by one, you can just find the difference between two y values. In this case, the difference is +5 each time, therefore, the slope or <em>m </em>is
5The intercept is where x=0. Since we know that (1,2) is a point, we subtract 5 from 2 to get the intercept. Therefore, the intercept is
-3
Therefore, the formula is y=5x-3
