Answer:

99inches

Step-by-step explanation:

The ratio of the sides of a triangle =2:4:9.

perimeter = 165 inches,

Total ratio= 2+4+9=15

perimeter = 165

Divide the perimeter by total ratio

165/15=11

Each of the sides

= (2×11) =22

(4×11) =44

(9×11)=99

the length of the longest side= 99inches

Arrange the graphs in descending order (from highest to lowest) based on the values of their correlation coefficients.

Basically, the closer they fit to the imaginary line of best fit, the higher they are

the closer the dots are to the imaginary line, te higher the number

D looks the closest together so that is first
A is a little farther apart
C is farther
B is farthers

DACB is order

Haley is 41 years old. Haley is 15 years less than seven times Marcy's age. How old is Marcie

blondinia [14]

Harley is 15 years less than seven times Marcy's age, so that means Haley + 15 = 7 * Marcy

Equation: (41 + 15) / 7 = 56 / 7 = 8

Marcy's age is 8.

What is the solution to the equation? 7x + 6 = -22

trapecia [35]

C.) x = -4 is the correct answer

Step-by-step explanation:

In order to solve the equation we have to isolate x on one side of equation

Given

7x + 6 = -22

Subtracting 6 from both sides

$7x+6-6=-22-6\\7x=-28$
