Answer: x=20
Step-by-step explanation:
The entire thing is equal to 180 degrees. so, 100+3x+x=180, which can be simplified to 100+4x=180. If we subtract 100 from both sides, we get 4x=80, 80 divided by 4 is 20, so x=20
Answer:
50
Step-by-step explanation:
to find the next number you times by -2.5
-16/5 = -3.2
-3.2 x -2.5 = 8
8 x -2.5 = -20
-20 x -2.5 = 50

12226 stores will be there in 2016
<em><u>Solution:</u></em>
<em><u>The growth function is given as:</u></em>
Where,
y is the future value
a is the initial value
r is the growth rate
t is the number of years
From given,
In 2000, a company had 1147 stores nationwide
By 2002, this total had grown to 1542
Therefore,
y = 1542
a = 1147
t = 2000 to 2002 = 2 years
r = ?
<em><u>Substituting we get,</u></em>
Taking square root of both sides
<em><u>If the number of stores continues to grow exponentially at the same rate, how many stores will there be in 2016?</u></em>
Therefore,
y = ?
a = 1147
r = 0.1594
t = 2000 to 2016 = 16 years
<em><u>Substituting we get,</u></em>
Thus 12226 stores will be there in 2016
7 is a solution
4 is extraneous

Answer:
g = 1/2
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
9 + 3.5g = 11 - 0.5g
<u>Step 2: Solve for </u><em><u>g</u></em>
- Add 0.5g on both sides: 9 + 4g = 11
- Subtract 9 on both sides: 4g = 2
- Divide 4 on both sides: g = 1/2
<u>Step 3: Check</u>
<em>Plug in g into the original equation to verify it's a solution.</em>
- Substitute in <em>g</em>: 9 + 3.5(1/2) = 11 - 0.5(1/2)
- Multiply: 9 + 1.75 = 11 - 0.25
- Add/Subtract: 10.75 = 10.75
Here we see that 10.75 does indeed equal 10.75.
∴ g = 1/2 is a solution of the equation.
