One number is three less than a second number. Six times the first is 6 more than 3 times the second. Find the numbers.
Karolina [17]

Step-by-step explanation:

Given,

x = y - 3

Also,

6(y - 3) = 3y + 6

6y - 18 = 3y + 6

6y - 3y = 6 + 18

3y = 24

y = 24/3

y = 8

x = 8 - 3

x = 5

Therefore, the first number is 5 and the second number is 8.

Elmer started out with$103 in his bank account .he spent $4 per week at the cafeteria for snacks.what is the slope (m) for this
pochemuha

Answer:

The equation is y=-4x+103

The slope is m=-4

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

y is the amount left in the saving account

x is the number of weeks

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

m=-\$4\ per\ week --> is negative because is a decreasing function

The y-intercept or initial value is

b=\$103

substitute

y=-4x+103

Two similar solids have surface areas of 48cm and 108cm respectively.find the volume of the smaller solid if the bigger one has
mestny [16]

Answer:

The volume of the smaller solid is 72 cm.

Step-by-step explanation:

Given that two similar solids have surface areas of 48cm and 108cm respectively, to find the volume of the smaller solid if the bigger one has a volume of 162cm the following calculation must be performed:

108 = 162

48 = X

48 x 162/108 = X

7776/108 = X

72 = X

Therefore, the volume of the smaller solid is 72 cm.

PLEASE HELP<br> solve for V
motikmotik

Answer:

-102.4 = v

Step-by-step explanation:

-15.9 = -3.1 + v/8

Add 3.1 to each side

-15.9 + 3.1 = -3.1+3.1 + v/8

-12.8 = v/8

Multiply each side by 8

-12.8 * 8 = v/8*8

-102.4 = v

How many dozens are there in 22 gross of nails
jonny [76]
One gross is 144 nails. You have to multiply 22 by 144 to see how many nails in total there are: 
22 * 144 = 3168
One dozen has 12 items. So in order to see how many dozens there are, you have to divide 3168 by 12:
3186 / 12 = 264

The correct answer is 264 dozens.
