Answer:
20 I'm pretty sure it's right but if not sorry
Step-by-step explanation:
80x.2=16
16÷.8= 20
5x + 2y = 7....multiply by -3
-2x + 6y = 9
----------------
-15x - 6y = -21 (result of multiplying by -3)
-2x + 6y = 9
---------------add
-17x = - 12
x = 12/17 or 0.7
5x + 2y = 7
5(12/17) + 2y = 7
60/17 + 2y = 7
2y = 7 - 60/17
2y = 119/17 - 60/17
2y = 59/17
y = 59/17 * 1/2
y = 59/34 or 1.7 when rounded <====
Answer:
A = 3228.2854
I = 1228.2854
Step-by-step explanation:
1 . Use the CI formula. (Reference in file.)
2. Solve equation after plugging the given information we have.
3. We will have the Amount after solving the equation.
4. To find interest we use formula A=P+I

thats the best i can do
Answer: " y = 30° " .
_____________________________________
<u>Note</u>: The sum total of the measure of all angles lying on a straight
line is 180°.
So; x + y + z = 180 .
Given: x = 2y ;
z = 3y ;
__________________
Find the value of: " y " ;
_______________________
Since: x + y + z = 180 ;
Substitute: "2y" for "x" ;
and: "3y" for "z" ;
_______________________
2y + y + 3y = 180 ;
6y = 180 ;
______________________
Divide EACH SIDE of the equation by "6" ; to isolate "y" on one side of the equation; and to solve for "y" ;
___________________________
6y/ 6 = 180 / 6 ;
y = 30 ;
____________________________
Let us check our work;
____________________________
2y + y + 3y = 180 ;
Substitute our solved value: "30" ; for "y" ; in the equation; to see if the equation holds true:
____________________________
2(30) + 30 + 3(30) =? 180 ?
____________________________
60 + 30 + 90 = ? 180 ?
____________________________
90 + 90 = ? 180 ? Yes!
