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>


The value of x for both angles to be vertically opposite is 27
<h3>Vertical angles</h3>
The measure of vertical angles are equal and they are angles that meet at the point of intersection of two lines.
In order to determine the value of x, we will equate both angles to have;
2x = 54
Divide both sides by 2
2x/2 = 54/2
x = 27
Hence the value of x for both angles to be vertically opposite is 27

Answer:
$618.80
Step-by-step explanation:
If the tablet is on sale for 15% off, you pay 85% of the original price.
85% of $700 is
700(0.85) = $595
You pay 4% sales tax on $595, which is
$595(0.04) = $23.80
The total cost you pay is $595 + $23.80 = $618.80
Answer:
a=g
Step-by-step explanation:
If you are solving for 'a', then you just need to get 'a' separated on its own. To do this, you can multiply both sides of the equation by 'g'. Now you have "a=1g" which simplifies into "a=g"
