Answer:

see explanation

Step-by-step explanation:

7 × $\frac{1}{7}$ = 1

Is an example of the inverse property for multiplication, that is

any number n multiplied by it's reciprocal $\frac{1}{n}$ = 1

given 5m - 4 = 14 ( add 4 to both sides )

5m = 18 ( divide both sides by 5 )

m = $\frac{18}{5}$

2 2/5 in kilometers in 3 3/4 minutes unit rate

Mars2501 [29]

Answer:

Step-by-step explanation:

d = r * t Divide both sides by t

r = d / t

d = distance = 2.25 km

t = time = 3 3/4 minutes = 3.75 minutes

r = 2.25 / 3.75

r = 0.6 km / minute

r = 3/5 km / minute

If the units are different than those given, please state them underneath my answer. I'll get to it as soon as I see your comment.

John made a triangle with all three sides the same length, 1 \frac{2}{3} ft. What is the perimeter of the triangle?

UNO [17]

Answer:

5 ft

Step-by-step explanation:

If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.

$1\frac{2}{3}$ × 3

$1\frac{2}{3}$ can be rewritten as $\frac{5}{3}$ , so:

$\frac{5}{3}$ × $\frac{3}{1}$

$= \frac{15}{3}$

The numerator & denominator share a common factor of 3, so:

5 ft is the final answer/perimeter.

hope this helps!
