Write and solve the equation and then check your answer. Which statements are true about the equation and its solution? Check
ch4aika [34]

The correct equation is n - 31 = 52

To check the solution, substitute 83 for the variable in the equation

This is an addition problem.

To solve the equation, add 31 to both sides.

Step-by-step explanation:

A number decreased by thirty-one is fifty-two

That means:

  • Subtract 31 from a number
  • The difference equal 52

Assume that the number is n

∵ The number is n

∵ When n decreased by 31 the answer is 52

∴ The equation is n - 31 = 52

The correct equation is n - 31 = 52

∵ n - 31 = 52

- To find n add 31 to both sides of the equation

∴ n - 31 + 31 = 52 + 31 ⇒ addition property

∴ n = 83

-To check the equation substitute n by 83 in the left hand side, the

  answer must be equal the right hand side

∵ Left hand side = 83 - 31 = 52

∵ Right hand side = 52

∴ n = 83 is correct answer

To check the solution, substitute 83 for the variable in the equation

This is an addition problem.

To solve the equation, add 31 to both sides.

Jacqueline is checking her bicycle’s wheel. The wheel has a radius of 20 cm, and its center is 51 cm above the ground. Jacquelin
Alex777 [14]

Answer:

h = 36.9 cm

Step-by-step explanation:

The function given to us is:

h(t) = 51 + 20 sin(225t)

Where h(t) is the function of the height in centimeters while t represents the time in seconds.

We have to find the height h(t) when the time is equal to 19 seconds.

Substitute t=19 into the given function

h(19) = 51 + 20 sin(225(19))

h(19) = 51 + 20 sin(4275)

h(19) = 51 + 20 (-0.7071)

h(19) = 51 + (-14,1421)

h(19) = 36.8579 cm

Rounding off to nearest 10th

h = 36.9 cm
