Answer: 22

Step-by-step explanation:

The mean is the average of the number.

Step 1 : Add up all the numbers

Step 2: Then divide by how many numbers there are

15 + 22 + 19 + 20 + 29 + 18 + 25 + 19 + 31 = 198

198 ÷ 9 = 22

The mean is 22

PLS HELP I WILL GIVE YOU Brainliest
Sindrei [870]

Answer:

3/2

Step-by-step explanation:

Because the problem tells you that the two triangles are similar, the value of a/b would be equivalent for both triangles. The fact that they are right triangles also indicates which sides are which in case the image was not drawn to scale. A is proportional to 2.1 and b is proportional to 1.4. So a/b= 2.1/1.4. This can reduce itself to 3/2 because both are divisible by .7

An integer 2 less than 4 times another. If the product of the two integers is 90 then find the integers
levacccp [35]

Let x and y be the 2 integers.

Then  x = 4y - 2

and xy = 90

Substitute for x in the second equation:-

(4y - 2)y = 90

4y^2 - 2y - 90 = 0

2y^2 - y - 45 = 0

(2y + 9)(y - 5) = 0

so y = 5    ( as it is an integer)

and x =  = 90/5 = 18


Answer:-  The 2 integers are 5 and 18.

4b+3=−9 i need help it is inportant
Fantom [35]

Answer:

b=-3

Step-by-step explanation:

4b+3=-9

    -3   -3

subtract 3 from both sides like so. 3-3 cancels out. -9-3=-12.

4b=-12

youre left with 4b=12 so DIVIDE 4b by 4 and -12 by 4

4b/4=-12/4

4b divided by 4 is 1. -12 divided by 4 is -3

b=-3

plug -3 in for b to make sure its correct

4(-3)+3=-9

-12+3=-9

-9=-9
