Answer:
x = 24.
r
0.
Step-by-step explanation:
2. The given equation is:

a) To eliminate the fractions multiply the equation throughout by the LCM of the denominators of the fraction. In this case, the LCM of (2, 3). The LCM is 6. So, multiply the entire equation by 6.
b) Half of the difference between an integer and 4 equals the sum of one - third of the integer and 2. Find the integer.
c) We have the equation:

Multiplying throughout by 6, we get:




Therefore, the solution of the equation is 24.
3. The given equation is: 
To solve for y:
We can rearrange the equation as:


or,
Note that we have to impose a condition on variable
. It would be that
can never be zero. i.e.,
. Otherwise, the value of
would be undefined.
Answer:

________

Step-by-step explanation:
Given

Line up the numbers

Multiply the top number by the bottom number one digit at a time starting with the ones digit left(from right to left right)
Multiply the top number by the bolded digit of the bottom number

Multiply the bold numbers: 1×4=4

Multiply the bold numbers: 2×4=8

Multiply the top number by the bolded digit of the bottom number

Multiply the bold numbers: 1×1=1

Multiply the bold numbers: 2×1=2

Add the rows to get the answer. For simplicity, fill in trailing zeros.

adding portion

Add the digits of the right-most column: 4+0=4

Add the digits of the right-most column: 8+1=9

Add the digits of the right-most column: 0+2=2

Therefore,

________

Volume for rectangular prism is l x w x h
12cm x 6.5cm x 1.25cm = 97.5cm^3
Step-by-step explanation:
1. 18(5)=90 18(6)=108
90*108= 9720
Her size of the original work was 9720 inches.
2. 1/2+1/2= 1 1/2=4 ft
The pole is 8 feet tall
3. 3 feet
3x+y=9 ....(1)
3x-5y=15. ......(2)
-[3x-5y=15]
=> 3x+ y = 9
-3x+5y=-15
..........................
0 +6y=-6
so,y=-1
3x+(-1)=9
3x=10
x=10/3
