If 9a+6b+4c=7, what is -24b-16c-36a

zheka24 [161]

Rearrange the 2nd equation

-36a-24b-16c

divide the whole thing by 4 and you'll get
-9a-6b-4c

you'll realize it looks the same as your first equation except that all the + has become minus so the answer will be -7 instead for your new equation
-9a-6b-4c=-7

multiply the whole thing by 4 and you'll get
-36a-24b-16c = -28

so the answer you want is -28

What is the value of x in the equation (x-2/3)+(1/60)=(5/6)

Roman55 [17]

<span>(x-2/3)+(1/60)=(5/6)
x-2/3= 5/6 - 1/60
x-2/3 = 49/60
x - 2 = 49/20
x = 49/20 + 2
x = 89/20

The mean of W is 55 ounces.

The standard deviation of W is 4.33 ounces.
