If no denominator equals zero, which expression is equivalent to 15/x-6+7/x+6
Answer: its d
Step-by-step explanation:
Given expression:
[tex]\frac{15}{x-6}+\frac{7}{x+6}[/tex]By taking L.C.M, we get
→ [tex]\frac{15(x+6)+7(x-6)}{(x-6)(x+6)}[/tex]
→ [tex]\frac{15x+90+7x-42}{x^2-36}[/tex]
→ [tex]\frac{22x+48}{x^2-36}[/tex]
Thus the response above i.e., "option D" is correct.

Estimate 154 divide 7
Answer:
22
Step-by-step explanation:
The result of 154 divided by 7 will be 22.
What is the rule of division?The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.
Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.
Since the given problem is not a large division. We can solve it by breaking 154 into two parts
______
7 / 154 \ 2 2
14
---------
1 4

---------
0
Therefore, 22 will come from dividing 154 by 7.

Answer: x = 1 and y = 2
Step-by-step explanation:
Solve for y in the first equation by adding 2x to both sides

Combine like terms and simplify
[tex]3x+8x=11\\11x=11\\x=1[/tex]
Now solve for the y value by plugging in x to any equation
[tex]y=2x\\y=2(1)\\y=2[/tex]

Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf, and gave 1/3 of the rest to his brother for an art project. How many inches was the piece Anthony gave to his brother.
Answer:
8 inches
Step-by-step explanation:
Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf
Step 1
The amount of board he used to build the shelf is calculated as:
= 3/4 of 8 foot board
= 3/4 × 8 foot
= 6 foot board.
Step 2
The amount of board left after building the shelf = The rest =
8 foot - 6 foot
= 2 foot
Step 3
We are told that he gave 1/3 of the rest to his brother for an art project
The amount of board he give his brother for an art project =
1/3 × 2 foot
= 2/3 foot
Step 4
How many inches was the piece Anthony gave to his brother?
We convert 2/3 foot to inches
1 foot = 12 inches
2/3 foot = x inches
Cross Multiply
x inches = 2/3 foot × 12 inches
x inches = 8 inches
Therefore, Anthony gave his brother 8 inches of board.
