Answer:

<h2>brainiest me</h2>

Step-by-step explanation:

The value returned is TRUE if all of the values in x are TRUE (including if there are no values), and FALSE if at least one of the values in x is FALSE. Otherwise the value is NA (which can only occur if na.rm = FALSE and ... contains no FALSE values and at least one NA value).

An architect believes that kitchens should be 2.25 times as long as they are wide. Set up a proportion and solve it to find how
White raven [17]

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.

Solve 7r+ 2 = 5(r – 4) ​
AveGali [126]

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
