A cyclist cycles a distance of 44 miles in a time of 4 hours.
What is her average speed?
Answer:
11 miles an hour
Step-by-step explanation:
44 miles divided by 4 hours would equal 11 miles in one hour, meaning her average speed would be 11 miles an hour
Answer:
The average speed is 11
Step-by-step explanation:
You would have 44 on top and 4 on the bottom(44/4)
then you would divide the 4 by four and the 44 by four to get 11 miles an hour.

The numerator of a fraction is 2 less than the denominator. A new fraction can be formed by adding 5 to the denominator and doubling the numerator. The product of the original fraction and the reciprocal of the new fraction is 1/4. What is the original fraction?
Answer:
[tex]\frac{6}{5}[/tex]
Step-by-step explanation:
let the denominator of the original fraction be x, then
[tex]\frac{x-2}{x}[/tex] ← original fraction
Then
[tex]\frac{2(x-2)}{x+5}[/tex] ← new fraction
The product of original and reciprocal of new is
[tex]\frac{x-2}{x}[/tex] × [tex]\frac{x+5}{2(x-2)}[/tex] ← cancel (x - 2)
= [tex]\frac{x+5}{2x}[/tex] = [tex]\frac{1}{4}[/tex] ( cross- multiply )
4(x + 5) = 2x
4x + 20 = 2x ( subtract 2x from both sides )
2x + 20 = 0 ( subtract 20 from both sides )
2x = - 20 ( divide both sides by 2 )
x = - 10
Then original fraction
[tex]\frac{x-2}{x}[/tex] = [tex]\frac{-12}{-10}[/tex] = [tex]\frac{6}{5}[/tex]

What is the solution to the equation 9(x − 2) = 27? (1 point) x = 2.5 x = 0.5 x = −0.5 x = 3.5
Answer:
x = 5
Step-by-step explanation:
9(x - 2) = 27
9x - 18 = 27
+18 +18
9x = 45

x = 5
A line that includes the point (1, 10) has a slope of 6. What is its equation in slope-intercept
form?
Answer:
y = 6x + 4Step-by-step explanation:
The point-slope form of the equation that describes the line with a slope of m and including the point (x₀, y₀) is: y - y₀ = m(x - x₀)
m = 6
(1, 10) ⇒ x₀ = 1, y₀ = 10
Therefore:
y - 10 = 6(x - 1) ← the point-slope form
y - 10 = 6x - 6 {add 10 to both sides}
y = 6x + 4 ← the slope-intercept form

error analysis: describe and correct the error in solving the equation.
1) the only solution of the equation x^2+6x+9=0 is x=9
Simplify the question above
Answer:
[tex]1 + \frac{3}{x} [/tex]
Step-by-step explanation:
1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.
[tex] \frac{ {x}^{2} - {3}^{2} }{ {x}^{2} - 3x} [/tex]
2) use difference of squares: a² - b² = ( a + b ) (a - b).
[tex] \frac{(x + 3)(x - 3)}{ {x}^{2} - 3x} [/tex]
3) Factor out the common term x.
[tex] \frac{(x + 3)(x - 3)}{ x(x - 3)} [/tex]
4) Cancle out x - 3 .
[tex] \frac{x + 3}{x} [/tex]
5) Simplify.
[tex]1 + \frac{3}{x} [/tex]

7/52 as a mixed number
Answer:7
Step-by-step explanation:
Answer:
[see below]
Step-by-step explanation:
[tex]\frac{7}{52}[/tex] is a proper fraction. Therefore, it cannot be written as a mixed number.
If you meant [tex]\frac{52}{7}[/tex]:7 can go into 52 7 times with 3 'parts' remaining.
This means that 7 is the whole number and the fraction is 3/7.
[tex]\frac{52}{7}=7\frac{3}{7}[/tex]
