The following formula can be used to find the distance that a person has run.
Mrrafil [7]
So distance = rate × time. You would do 3/4 × 5.5, which would get you 4.125.

MZRSK = x + 53, m KST = x + 109,<br> and mZRST = 156º<br><br><br> Find x.
Dahasolnce [82]

Answer:

-3 = x

Step-by-step explanation:

Since we are not given a midpoint, we use the Angle Addition Postulate:

156 = [x + 109] + [x + 53]

156 = 162 + 2x

-162 - 162

_______________

−6 = 2x

___ ___

2 2

−3 = x

[−3 + 53] + [−3 + 109] = 156

50 106

156 = 156 ☑

Therefore, -3 = xis a genuine statement.

Tanya took a cab from her home to the airport. Her total fare including a tip of $5.00, was $28.50. EZ Cab Company has a pick-up
ValentinkaMS [17]
16.2 miles.

Since she paid a $5 tip, the cost for her fare was $23.50.  Let x be the number of 0.2-mile increments in the trip:
23.50 = 2.50 + 1 + 0.25(x-1)

This equation comes from the 2.50 home pick-up fee; $1 for the first 0.2-mile increment; and 0.25 for each other 0.2-mile increment.

Using the distributive property, we have:
23.50 = 2.50 + 1 + 0.25*x - 0.25*1
23.50 = 2.50 + 1 + 0.25x - 0.25

Combining like terms,
23.50 = 0.25x + 2.75

Subtracting 2.75 from both sides, we have:
23.50 - 2.75 = 0.25x + 2.75 - 2.75
20.25 = 0.25x

Dividing both sides by 0.25, we have:
20.25/0.25 = 0.25x/0.25
81 = x

This means there are 81 0.2-mile increments in her trip.  81(0.2) = 16.2 miles

Megan went to the beach 34 times last summer. She went 6 more times in July than she did in June. She went twice as many times i
Irina-Kira [14]
<span>Megan went to beach 34 times last summer.
June =  x
July = 6 * june
August =  2 * june
Thus Let’s find the value of june, which is the value of x as a variable:
Equation:
x + 6x + 2x = 34
Solution:
=> x + 6x + 2x = 34
=> 9x = 34
=> 9x / 9 = 34 / 9
=> x = 3.7778, since this is a decimal, let’s round this off to 3.78
Let’s check our answer
=> 4 + 6(4) + 2(4)
=> 4 + 24 + 8
=> 36 approximately.</span>
