1: Identify the angle.
<em>The following angle is a 90.</em>
2: Set up the equation.
<em>x + (3x + 10) = 90</em>
3: Combine like terms.
<em>4x + 10 = 90</em>
4: Solve for x.
<em>4x + 10 = 90</em>
<em> -10 = - 10</em>
<em>--------------------------</em>
<em>4x = 80</em>
<em>------------------</em>
<em>4 4</em>
<em>x = 20</em>
Your answer is x = 20.

Answer:
50 items were sold for $75

Answer:
The amount invested in CDs is $1,340
The amount invested in the stock portafolio is $6,900
The amount invested in the saving accounts is $2,300
Step-by-step explanation:
Let
x ---->the amount invested in CDs at 2.1%
y ---> the amount invested in the stock portfolio at 2.5%
z ---> the amount invested in the savings account at 1.5%
----> equation A
----> equation B
substitute equation B in equation A
----> equation C
we know that
The total interest earned by the three amount must be equal to $231.69
so
----> equation D
substitute equation B and equation C in equation D
solve for y
<em>Find the value of x</em>
<em>Find the value of z</em>
so what was the question again?
Answer:
Step-by-step explanation:
Okay so because it's 10% off you're going to take the original price ($25) and move the decimal over once. So, $2.50. Now back to the original price!
$25.00 - $2.50 = $23.50 for the sweatshirt. I don't think I explained that very well, but that'd be how you found your answer?
