Answer:
C. (0,1)
Step-by-step explanation:
x + 1 = -2x + 1
3x = 0
x = 0
y = (0) + 1
y = 1
Answer:
20,4
Step-by-step explanation:
Suppose that x, y are the the length and width
Area=x*y=80
Parameter=2(x+y)=48....x+y=24
Xy=80...x(24-x)=80...x=20,y=4
Answer:
x = 24
Step-by-step explanation:
Given that:
(x+3)/3 = 9
multiplying both sides by 3
(x+3) = 9*3
(x+3)= 27
Subtracting 3 from both sides
x= 27-3
x=24

Answer:
b) 3cd+3 1/3c-3d
Step-by-step explanation:
It can work well to factor the variables out so you can see the coefficients more easily:
6cd+3c-7d-3cd+4d+1/3c
= (6 -3)cd +(3 +1/3)c +(-7 +4)d
= 3cd +(3 1/3)c -3d
Answer:
Step-by-step explanation:
A coefficent is the number in front of the letter and a constant is just a number
