in the addition problem on the right, each letter stands for a digit and different letters stand for different digits. What digits do the letters H,E, and A each represent?
H E
H E
H E
+ H E
____________
A E

Answers

Answer 1

Answer:

This problem is easy but I'll demonstrate an approach for simplifying these kind of problems that can be applied to problems of higher complexity.

Key: Notice that you can write AH as 10A + H and HEE as 100H + 10E+E, and thus

AH +A = HEE

10A + H + A = 100H + 10E +E

11A + H = 100H + 11E

11A = 99H + 11E

A = 9H + E

As H can not be 0 (it is the leading digit in HEE), A must be at least and therefore exactly 9 and the problem solves itself from there on.

How would you solve this problem? (Worth 10 points, pls help!)

Answers

Answer:

(22,0)

Step-by-step explanation:

1. Select any two points given and find their slope (rise/run)

       (-38, 40) and (-23, 30)

      slope =   [tex]\frac{40-30}{-38-(-23)}[/tex] = - 2/3

2. Use the slope and one of the points to create an equation of the line in the format y = mx + b, where m = slope and b = y-intercept.

    y = mx + b ⇒ 40 = -2/3 (-38) + b

3. Solve for b

   40 = -2/3 (-38) + b

   40 = 76/3 + b

   40 - 76/3 = b

   b = 44/3

4. To find the x-intercept, set y = 0, and solve.

   y = -2/3 x + 44/3

   0 = -2/3 x + 44/3

   2/3 x = 44/3

   x = 22

Question 10 options:

Low tide


Spring tide


High tide


Neap tide

Answers

Answer:

Whenever the earth, moon and sun are aligned, the gravitational pull of the moon is augmented by the gravitational pull of the sun, causing larger than average tidal ranges — meaning especially high high tides and very low low tides. These extreme tides are called “spring tides.”

2(3y + 7 + 5) = 196 - 16
what’s the value of y?
And tell me how you know this and why or Y ahahahahahaha

Answers

Answer:

y=60

Step-by-step explanation:

196 - 16 = 180

7 + 5 = 12

12 + 3y = 15y

2 * 15y = 30y

180 ÷ 30 = 60

y = 60

Answer:

y=26

Step-by-step explanation:

Let's solve your equation step-by-step.

2(3y+7+5)=196-16

Step 1: Simplify both sides of the equation.

2(3y+7+5)=196-16

(2)(3y)+(2)(7)+(2)(5)=196+-16 (Distribute)

6y+14+10=196+-16

(6y)+(14+10)=(196=-16) (Combine Like Terms)

6y+24=180

Step 2: Subtract 24 from both sides.

6y+24-24=180-24

6y=156

Step 3: Divide both sides by 6.

6y/6 = 156/6

y=26

Finding the tip amount:
(56.5)(22)=1,243
1,243/100=12.43
The tip amount is $12.43.
Finding the total cost:
56.50+12.43=68.93
The total cost of the meal with tip included is $68.93.
56.50 * .22 = 12.43
56.50 + 12.43 = $68.93

Answers

I don’t know the answer but you would have to first convert the 2.625 inches into cm and then convert the cm to mm to get your answer
Convert 2.625 inches into centimeters and then convert it again but in millimeters you will get 66.7mm
No need to find diameter because it was given there in inches just convert

2.625 inches = 6.67 centimeters
6.67cm = 66.7mm

(219,379.01 - x) / x = .3321

Answers

Answer:x = 164686.592598

Step-by-step explanation:

219379.01−x/x = 0.3321

−x+219379.01/x = 0.3321

Step 1: Multiply both sides by x.

−x+219379.01≈0.3321x

−x+219379.01 − 0.3321x = 0.3321x−0.3321x (Subtract 0.3321x from both sides)

−1.3321x + 219379.01 = 0

−1.3321x + 219379.01 − 219379.01 = 0 − 219379.01 (Subtract 219379.01 from both sides)

−1.3321x = −219379.01

−1.3321x/−1.3321 = −219379.01/−1.3321

(Divide both sides by -1.3321)

x = 164686.592598

Answer:

  164,686.59

Step-by-step explanation:

Carry out the division, then solve for x.

  (219,379.01 - x) / x = .3321 . . . . . given

  219,379.01/x -1 = 0.3321

  219,379.01/x = 1.3321 . . . . add 1

  219,379.01/1.3321 = x ≈ 164,686.59 . . . . multiply by x/1.3321

Rounded to 8 significant digits, the value of x is 164,686.59.

3/4c-7/12+7/24c+2/3-1/6c
simplify the expression

Answers

Answer: 7/8c + 1/12

Explanation: separate the c terms and the non-c terms. 3/4c + 7/24c - 1/6c = 7/8c

-7/12 + 2/3= 1/12

therefore, it’s 7/8c + 1/12

The simplification of the given expression (3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c is (21/12)c + 1/12.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given expression,

(3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c

Combined likely terms,

⇒ (3/4)c + (7/24)c - (1/6)c - 7/12 + 2/3

⇒ (3/4 + 7/24 - 1/6)c + 2/3 - 7/12

⇒ [(18 + 28 - 4)/24]c+ (8 - 7)/12

⇒ (42/24)c + 1/12

⇒ (21/12)c + 1/12

Hence "The simplification of the given is (21/12)c + 1/12".
