5x + 2y = 13
x + 2y = 9
Subtract :- ( note that 2y - 2y = 0):-
4x + 0 = 4
x = 1
From 2nd equation plug in x = 1
1 + 2y = 9
2y = 8
y = 4
Solution to this equation is x=1,y=4
2x + y = 7
5x - y = 14
Adding eliminates the y terms because y + -y = 0 :-
7x + 0 = 21
7x = 21
x = 3
Plug x=3 into second equation:-
5(3) - y = 14
y = 15-14 = 1
solution is x =3, y = 1
<em>What is X?</em>
<em>I say that X = 2</em>
Question:
Felicia makes ½ gallon of fruit punch. She pours an equal amount into 8 glasses.
What fraction of a gallon fruit punch is in each glass?
Answer:
The fraction of a gallon fruit punch is in each glass is 1/16
Step-by-step explanation:
Given
Size of fruit punch = ½ gallon
Number of glass = 8
Required
Fraction of a gallon fruit punch is in each glass?
To solve this question, the following assumption has to be made.
- The 8 glass cups are of equal sizes.
Having said that;
The interpretation of the question is that, the fruit is evenly distributed into the 8 glass cups.
Mathematically, the size of the fruit punch will be divided by the number of glass cups.
So, we have
Fraction = ½ ÷ 8 (convert ÷ to *)
Fraction = ½ * ⅛
Fraction = 1/16
Hence, the fraction of a gallon fruit punch is in each glass is 1/16
We know that :
⊕ Sum of the interior angles in a Pentagon should be equal to 540°
⇒ x° + (2x)° + (2x)° + 90° + 90° = 540°
⇒ (5x)° = 540° - 180°
⇒ (5x)° = 360°
⇒ x° = 72°
