Answer:

Step-by-step explanation:

ΔABC & ΔADE are similar triangles

\frac{AD}{AB}=\frac{DE}{BC}\\\\\frac{10+x}{10}=\frac{10}{6}\\\\

Cross multiply,

6*(10+x) = 10*10

6*10 + 6*x = 100

60 + 6x = 100

6x = 100 - 60

6x = 40

x = 40/6

x = 6.67

Answer:

In triangle ABC and triangle ADE

angle A = angle A (common)

anhle ABC = angle ADE

By AA , triangle ABC similar to triangle ADE

Thus

AB/AD = BC/DE

10/(10+x) = 6/10

60 + 6x = 100

6x = 40

x = 6.67

A store sells peanuts by the pound. Jerry paid 4.59 for 5.4 pounds of peanuts. At that rate, how much would he pay for 7.8 pound
nikdorinn [45]
If $4.59 = 5.4 peanuts
         $x = 7. 8 peanuts

Cross multiply and you get:

5.4x = (4.59)(7.8)
      x = ((4.59)(7.8)) / 5.4
      x = $6.63

Noah’s remote control car moved 12 feet in 6 seconds. Which graph has a slope that best represents Noah’s car’s average rate of
vaieri [72.5K]

We want to find a graph that represents Noah's average speed.

We define the average speed as the quotient between the distance moved and the time it takes to move that distance, then in this case we will have:

s = 12ft/6s = 2ft/s

Then we can define a linear equation:

y = (2ft/s)*x

As the distance that Noah travels in x seconds.

The graph of the given linear function can be seen below, and that is the graph with the slope that best represents Noah's average speed.
