Answer:

AB = 30 units.

Step-by-step explanation:

Given that in a triangle ACE, B and D are mid points of AC and CE respectively.

By triangle theorem for mid points, we have

BD = 1/2 AE

Since AE is given as 60, we get BD =30

But BD also equals 3x (given)

So 3x=30 or x =10

Substitute in AC to get AC = 5x+10 = 5(10)+10 = 60

AB = 1/2 AC = 1/2 (60) = 30 units.

Oxana [17]
D- 1.65 per hot dog

Take the amount of the bag of chips which is 1.25 and multiply it by 5 because that’s how many people there are and they each bought one bag
1.25 x 5= 6.25
Next you want to subtract that amount from the total so we can just have the amount of money spent on hot dogs
22.27-6.25=16.50
Then you want to divide 16.50 by 5 because they all bought the same amount of hot dogs and this will get us to the amount of to hot dogs
16.50/5=3.30
Finally you want to divide 3.30 by 2 which will get us the price for 1 hot dog
3.30/2=1.65

There you go!!

Which equation represents a proportional relationship?
asambeis [7]

Given:

Four equations in the options.

To find:

The equation which represents a proportional relationship.

Solution:

If y is proportional to x, then

y\propto x

y=kx

where, k is the constant of proportionality.

In this case if x=0, then y=0. It means the graph of a proportional relationship passes through the origin.

From the given options, only option B, i.e., y=\dfrac{1}{4}x, is of the y=kx, where, k=\dfrac{1}{4}.

So, the equation y=\dfrac{1}{4}x represents a proportional relationship.

Therefore, the correct option is B.
