9(-8m + 10) + 4(6m + 9)

m= -2.625

Step-by-step explanation:

9(-8m + 10) + 4(6m + 9)

-72m + 90 + 24m + 36

-48m = 126

m = -2.625

-48m + 126

Step-by-step explanation:

9(-8m + 10) + 4(6m + 9)

use distributive property

9(-8m + 10)

=

-72m + 90

and

4(6m + 9)

=

24m + 36

-72 + 36 + 90 + 36

combine like terms

(-72m + 36) + (90+36)

=

-48m + 126

Your answer is

-48m + 126

unless you're asking what m is. It's -2.623 (decimal form) , -21/8 (exact form) , -2  5/8 (mixed number)

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
