Answer:
x= 2,
,y = 5
Step-by-step explanation:
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 5x - 5
// Plug this in for variable y in equation [2]
[2] -4x + 2•(5x-5) = 2
[2] 6x = 12
// Solve equation [2] for the variable x
[2] 6x = 12
[2] x = 2
// By now we know this much :
x = 2
y = 5x-5
// Use the x value to solve for y
y = 5(2)-5 = 5
Solution :
{x,y} = {2,5}
Let the numbers be a and b, then ab=0.2 and a/b=0.8, so a=0.8b. Therefore, 0.8b^2=0.2 and b^2=0.2/0.8=2/8=1/4 and b=+1/2 or +0.5 and a=+0.8*0.5=+<span>0.4. The two numbers are therefore 0.5 and 0.4 or -0.5 and -0.4. The quotient is 0.4/0.5</span>
Answer:
Quadrilateral ABCD does not map onto itself using a reflection because it has 0 lines of symmetry.
Step-by-step explanation:
Remember that a trapezoid has no lines of symmetry.
The arrangement of the fraction from least to greatest is 5/11, 2/3 and 7/8.
<h3>What is a fraction?</h3>
A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers
The fraction can be changed to percentage to make it easier.
7/8 = 7/8 × 100 = 87.5%
5/11 = 5/11 × 100 = 45.5%
2/3 = 2/3 × 100 = 66.7%
The arrangement is 5/11, 2/3 and 7/8.
