The answer is A
You can solve this by equation the two equations, by substitution method or elimination. Let's choose the substitution since Equation 2 has already X isolated
-take the X in equation 2 and substitute in the first equation
So, You should have 5 (5-3/2 y) -4y =7
Get y ( I'll assume you know how to simplify and find y by yourself )
y=36/23
-Now take y and substitute it in the first equation or the second equation (it doesn't really matter)
Substituting y in Equation 2:
x=5- 3/2 (36/23)
=> x= 61/23
So answer is A where (x,y) is (61/23, 36/23)
Answer:
Infinite Decimals.
Rational numbers can be represented as a fraction.
Infinite decimals cannot be represented as fractions, therefore they are not rational.
There is only one solution
Answer:
Its area is 40cm² and perimeter is 26cm
Step-by-step explanation:
As the formula of area of rectangle is A=length×breath and the perimeter is P=2length+2breath so we can just substitute the following values to the formula:
length = 8cm
breath = 5cm
A = 8 × 5
= 40cm²
P = 2(8) + 2(5)
= 26cm
