Shane went bowling with his friends. The bowling alley charges $20 for an hour of group bowling plus a fee to rent each pair of

ValentinkaMS [17]

Answer:

4x+20=31

Step-by-step explanation:

So one hour of bowling is 20 dollars and they bowled for one hour hence the 1x20 which is equal to 20. That is the base coast we add to the variable of x that is the cost of renting one pair of shoes. And since they rented 4 pairs of shoes you multiply x by 4 to get 4x. Add the 20 dollars they paid to bowl and it is 4x+20. They paid 31 dollars in total so equal the equation to 31. 4x+20=31. Solution is $2.75 per pair of shoes.

The numerical expression, 2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3 = 67/24 on simplification using the BODMAS rule.

In the question, we are asked to simplify the numerical expression:

2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3.

To simplify the expression, we will follow the BODMAS rule, where B means Brackets, O means Of, D means Divide, M means Multiplication, A means Addition, and S means Subtraction.

2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3

= 2/3 ÷ 16 + (3/4 + 1/6) ÷ 1/3 {Solving 2⁴ = 16, before proceeding BODMAS}.

= 2/3 ÷ 16 + ((9+2)/12) ÷ 1/3 {Solving Brackets by taking LCM}

= 2/3 ÷ 16 + 11/12 ÷ 1/3 {Simplifying}

= 2/3 * 1/16 + 11/12 * 3/1 {Solving divisions by taking reciprocals}

= 1/24 + 11/4 {Multiplying}

= (1 + 66)/24 {Adding using LCM}

= 67/24 {Simplifying}.

Thus, the numerical expression, 2/3 ÷ 2⁴ + (3/4 + 1/6) ÷ 1/3 = 67/24 on simplification using the BODMAS rule.

Find the surface area of a cylinder with a diameter of 18 and a height of 32. Use 3.14 for π. Round your answer to the nearest t

Ksenya-84 [330]

Answer: a = 2,315.5

Step-by-step explanation:

a = 2πrh+2πr²

a = 2π(9)(32) + 2π9²

a = 2π x 288 + 2π x 81

a = 1809.6 + 508.9

a = 2,315.5

Y=6x – 11 -2x – 3y =-7

Eva8 [605]

Answer:

x=2 and y=1

Step-by-step explanation:

1). Plug the y value into the second equation. It will look like the following afte you plug in what y equals:

-2x-3(6x-11)=-7

2). Then, you distribute the "-3" to all the terms inside the parenthesis.

-2x-18x+33=7

3). Then, you subtract the positive 33 from both sides to try to get the x alone on one side.

-2x-18x=-40

4.) Then, you combine all of the terms containing an x.

-20x=-40

5). Finally, you divide both sides by -20 and the outcome is x=2.

6). Hold up...we ain't done yet..

7). Next, you have to plug the x back into the either equation to get the outcome of what y will be, but for this purpose I will plug it back into the first equation.

y=6(2)-11

8). I will then distribute the 6 into the all the terms in the parenthesis and then it will look like this.

y= 12-11

9). Do the math...and the answer is y=1.
