second one
Step-by-step explanation:
just multiply by -9 and see which one fits in
This is true because it is an unknown number so it is replaced by a variable.
Answer:
2.71 feet
Step-by-step explanation:
An architect believes that kitchens should be 2.25 times as long as they are wide.
This means
Width of kitchen = 2.25 × Length of the Kitchen
W = 2.25L
L = W/2.25
We are asked: how long a kitchen should be if it is 6.1 feet wide.
We have the proportion
L = W/2.25
W = 6.1
L = 6.1/2.25
L = 2.7111111111 feet
Therefore, the length of a kitchen = 2.71 feet when the kitchen is 6.1 feet wide.
Multiply the bracket by 5
I used PEMDAS
P= parenthesis
E= exponents
M=multiplication
D= division
A= addition
S= subtraction
7r+2= 5(r-4)
7r+2= 5r-20
Move 5r to the left hand side . Positive 5r changes to negative 5r
7r-5r+2= 5r-5r-20
2r+2=- 20
2r+2-2= -20-2
Move positive 2 to the right hand side. Changes to negative -2
2r+2-2= -20-2
2r= -22
Divide by 2 for 2r and -22
2r/2= -22/2
r= -11
Answer is r= -11
