Solve for n <br><br> 11/6=n+7/9<br><br><br> (Plz no trolling; will mark brainiest)
xxTIMURxx [149]

Answer:

n=\frac{19}{18}

Step-by-step explanation:

Ir order to find the value of n in the given linear equation: \frac{11}{6} = n + \frac{7}{9} you have to perform the properties of equalities to obtain an equivalent equation.

You have to perform these properties in each side of the equation.

Applying the subtraction property (which is the subtraction of the same number to each side of the equation):

Adding \frac{7}{9} to each side:

\frac{11}{6} - \frac{7}{9} = n + \frac{7}{9} - \frac{7}{9}

This way you can obtain the value of n

\frac{11}{6} - \frac{7}{9} = n

Solving the subtraction of the fractions and simplifying:

\frac{(11)(9)-(7)(6)}{(6)(9)} = n\\\frac{57}{54} = n\\n=\frac{19}{18}

Find the radius of a circle in which the central angle, a, intercepts an arc of the given length
Nataly [62]

Answer:

17.2 in

Step-by-step explanation:

The formula for arc length is s = rФ.  Here we are to find r.  Solving this formula for r, we get:

r = s/Ф

So, in this problem, r = (9 in) / (π/6) = 54/π in ≈ 17.2 in

-25/J = 5<br> 16 + s = -90<br> 13 + t = 51<br> r/10 = (-6)<br> a + -12 =45
alexandr1967 [171]

we conclude that the solution for the given algebraic expressions are:

  • J = -5
  • s = -106
  • t = 38
  • r = -60
  • a = 57

<h3>How to solve these algebraic expressions?</h3>

Here we have some simple algebraic expressions:

The first one is:

-25/J = 5

We want to solve this for J.

Remember that we can perform the same operation in both sides of the equation, then we cans tart by multiplying both sides by J.

(-25/J)*J = 5*J

-25 = 5*J

Now we can divide both sides by 5, so we isolate J:

(-25)/5 = (5*J)/5

-5 = J

We conclude that the solution is J = -5.

Now, similarly for the other equations we have that:

16 + s = -90

Here we subtract 16 in both sides:

s = -90 - 16 = -106

13 + t = 51

Here we subtract 13 in both sides:

t = 51 - 13 = 38

r/10 = (-6)

Here we multiply both sides by 10:

r = (-6)*10 = -60

a + (-12) = 45

Here we add 12 in both sides:

a = 45 + 12 = 57

Then we conclude that the solution for the given algebraic expressions are:

  • J = -5
  • s = -106
  • t = 38
  • r = -60
  • a = 57

A circular running track is 1/4 mile long. Jamie runs on this track, completing each lap in 1/20 of an hour. What is Jamie’s run
Grace [21]

Answer: The running speed of Elena is 5 miles/hour and this can be determined by using the formula of speed.

Step-by-step explanation:

A circular running track 1/4 is a mile long.

Elena runs on this track, completing each lap in 1/20 of an hour.

Speed formula is used to determine the speed of Elena. The formula of speed is given by:

   ----- (1)

where S is the speed, D is the distance and T is the time taken by Elena to run a circle.

Now, put the value of distance D and time T in the equation (1).

Speed = 5 miles/hour

Therefore, the running speed of Elena is 5 miles/hour.
