You can set up an equation so lets assume ellens age is e. three times ellens age would be 3e so when 60 is subtracted you do 3e-60, as this results in her age you can say that 3e-60=e
You can take away the e from both sides and get 2e-60=0. If you add the 60 to both sides, you get 2e=60. When you divide 60 by 2 you get 30. Therefore, ellens age is 30

P, Q, V, and K are collinear with V between K and P, and Q between V and K. If VP = 14x + 4, PK = x + 630, VQ = 17x + 6, and KQ

Ierofanga [76]

It's given in the question,

P, Q, V and K are collinear.

VP = 14x + 4

PK = x + 630

VQ = 17x + 6

KQ = 11x + 5

By segment addition postulate,

KQ + VQ + VP = KP

Substitute the values in the expression,

(11x + 5) + (17x + 6) + (14x + 4) = x + 630

(11x + 17x + 14x) + (5 + 6 + 4) = x + 630

42x + 15 = x + 630

42x - x = 630 - 15

41x = 615

x = $\frac{615}{41}$

x = 15

Therefore, value of VP = (14x + 4)

= 14(15) + 4

= 214 units

One day, a sprinter runs the 100 m dash 24 times, for a total distance of 24 00 m. how many kilometers did the sprinter run?

tigry1 [53]

The total distance that was covered by the sprinter in Kilometers is:

2.4 Km

<h3>How much is the total distance covered?</h3>

To obtain the total distance covered by the sprinter, we need to first realize that 1 Km is equal to 1000 meters. That said, the question above requires us to change 2400 meters to kilometers.

Thus we will have:

2400 Meters * 1 km / 1000 meters

= 2.4 km

So, the total distance covered by the sprinter in kilometers is 2.4
