6 0

Answer:

The given equation has NO solutions

Step-by-step explanation:

Given equation as :

- 14 (z - 5) = - 14 z + 70

Or, - 14 z + 70 = - 14 z + 70

Since the coefficient of variable z is same on both side i.e ( - 14 ) , So , the Given equation has NO - solution .

Hence the given equation has NO solutions Answer

A circle has a radius of 5 ft, and an arc of length 7 ft is made by the intersection of the circle with a central angle. Which e

kirill115 [55]

We can use the arc length formula to solve this.

Arc length = $\frac{q}{360}*2\pi r$

Given arc length is 7 and radius is 5, we can plug in the values and solve for q.

$7=\frac{q}{360}*2\pi (5)\\7=\frac{q}{360}*10\pi \\7=\frac{10\pi q}{360}\\7=\frac{\pi q}{36}\\7*36=\pi q\\252=\pi q\\q=\frac{252}{\pi}\\q=80.21$

ANSWER:

We can use the equation $7=\frac{q}{360}*2\pi (5)$ to find the value of q. And, the value of q is 80.21°.

The length of each side of an equilateral triangle is increased by 5 inches, so the perimeter is now 60 inches. Write and solve

AfilCa [17]

Answer:

The original length of each side of the equilateral triangle = x =15 inches

Step-by-step explanation:

Let Original length of side of equilateral triangle = x

If it is increased by 5 inches, the length will become = x+5

Since in equilateral triangle all the ides have same length so,

New Length of side 1 = x+5

New of side 2 = x+5

New Length of side 3 = x+5

Perimeter of triangle = 60 inches

We need to find the value of x

The formula used is: $Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3$

Putting values in formula and finding x

$Perimeter=Length \ of \ side \ 1 \ + Length \ of \ side \ 2 \ + Length \ of \ side \ 3\\60=x+5+x+5+x+5\\60=3x+15\\60-15=3x\\45=3x\\x=\frac{45}{3}\\x=15$

So, the original length of each side of the equilateral triangle = x =15 inches
