Change one number in the equation below to safely land the plane: y=2x-7

Answer:

13x2 is 26

Step-by-step explanation:

Answer: The answer is 13.

Step-by-step explanation: This is because if you set up the equation

2x = 26 then you divide by 2 on each side, this would leave you with x = 13 which is the answer.

 Question 1128242: The product of the three ages, in years of three teenagers is 4590. None of the teens are the same ages. What are the ages of the three teen ages? (Use guess and check)

A hat and a jacket cost $100. The jacket cost $90 more than the hat. What are the cost of the hat and the cost of the jacket?

Melody picks a number. She doubles the number, squares are result, divide the square by 3 subtracts 30 from the quotient and gets 18. What are the possible numbers that Melody could have picked? What operation does Melody perform that prevents us from knowing 100% certainly which she picked?

You can put this solution on YOUR website!

These are three very different problems. The rules of the forum are one problem per post. Please follow those rules in the future.

(1) Certainly guess and check is the easiest way to solve this problem, since you know the three ages are whole numbers. But you should be able to get to the solution with very few if any wrong "guesses" by making your guesses logically.

The product of the three ages is a multiple of 10, and therefore a multiple of 5; since all three ages are in the teens, one of them has to be 15. Then 4590/15 = 306.

You could do guess and check again from there. However, if you note that both the other ages have to be greater than 15, and you know the last digit of the product has to be "6", then the only possible pair of ages is 17 and 18. And indeed 17*18 is 306.

ANSWER: The ages are 15, 17, and 18.

(2) Here is an informal solution method using logical reasoning.

Take away the "extra" $90 that the jacket costs; you are left with a jacket and a hat that each cost the same, and the total is now $100-$90 = $10. That means each of them costs $5. Now add those extra $90 back on to the price of the jacket.

ANSWER: The jacket costs $95; the hat costs $5.

(3) Melody picks a number: Call it x.

She doubles the number: It is now 2x.

She squares are result: It is now (2x)^2 = 4x^2.

She divides the square by 3: It is now 4x^2/3.

She subtracts 30 from the quotient: It is now 4x^2/3-30.

The number she ends up with is 18.

Solve the equation that says 4x^2/3-30 = 18:

4x%5E2%2F3-30+=+18

4x%5E2%2F3+=+48

4x%5E2+=+144

x%5E2+=+36

x+=+6 or x+=+-6

ANSWER: The two possible starting numbers are 6 and -6. We get two possible answers because of the step where she squares the number.

Answer:

7 18-year olds

Step-by-step explanation:

The product is 2,971,987,200. 18^7 is 612,220,032. However, 18^8 is 11,019,960,576, which is too big. So, 7 is the answer

P=145.8m

Step-by-step explanation:

Answer: The perimeter is 145.8 square meters

Step-by-step explanation:

Area=513.5 square meters

513.5=l (length) times w (width)

513.5= 7.9 times w

513.5= 7.9w

(DIVIDE 513.5 AND 7.9 BY 7.9)

65= w

Perimeter= 2l + 2w

Perimeter=2(7.9) + 2(65)

Perimeter=15.8 + 130

Perimeter=145.8 square meters

Answer:

68

Step-by-step explanation:

x + x = 136

2x = 136

x = 136 / 2

x = 68

Answer:

• This triangle is isosceles hence two angles are equal.

• But, the sum of two interior angles are equal to the exterior angle.

[tex]{ \rm{x + x = 136 \degree}} \\ \\ { \rm{2x = 136 \degree}} \\ \\ { \boxed{ \rm{ \: \: x = 68 \degree \: \: }}}[/tex]

Answer: 3.1

Step-by-step explanation:

Firstly, let's put 2/8 as a decimal. If we simplify 2/8, it would be 1/4. And what is the decimal of 1/4? 0.25

Now that we've got our decimals it would be easier to calculate.

12.4 * 0.25 = 3.1

Answer:

60 degrees

Step-by-step explanation:

I see 3 lines in the graphic.

1 horizontal line that gets crossed by 2 other lines - one at a 25 degree angle (and that line ends at the crossing point), and one at 60 degrees.

so, above and below the horizontal line, the line with 60 degrees and x degrees is the same line.

and therefore, as per the laws of crossing lines, the angles above and below the crossed line must be the same. they are just left-right mirrored.

therefore, x must be the same as the diametrically opposing angle above the horizontal line. and that is 60 degrees.

Answer:

∠p, ∠q, and ∠r are all 40°

Step-by-step explanation:

ARQ is a triangle so the sum of the interior angles must equal 180°

48 + 52 = 100

180 - 100 = 80°

This means that the last angle, 2p = 80°

If 2p = 80, then ∠p = 40° (divide by 2)

PQR is also a triangle which means PR is a straight line

The angle next to 2p is going to be 100, because 2p was 80 and angles on a straight line add to 180° (180 - 80 = 100)

∠r = ∠p because they are alternate angles (in the sideways Z shape), 40°

∠q can be found by doing:

180 - (∠PAQ + ∠r)

= 180 - (100 + 40)

= 180 - 140

= 40

Answer:

BIDMAS

Step-by-step explanation:

In order to solve equations correctly, we use BIDMAS ( Brackets, Indices, Division, Multiplication, Addition and Subtraction).

For example, if we have 5+2x7, we would multiply 2 by 7 first, then add 5 to the value.
