Answer:

Li can walk 6 miles

Step-by-step explanation:

We can use proportions to solve this. Put miles over minutes

2 miles x miles

----------- = ---------------

45 minutes 135 minutes

Using cross products

2 * 135 = 45x

270 = 45x

Divide by 45

270/45 = 45x/45

6=x

Li can walk 6 miles

Taxi ride is 1.85 per mile with an initial 2.75 charge, what is the cost in dollars for a 20 mile taxi ride

kati45 [8]

Answer:$39.75

First, we have to find out how much would it be for a 20 mile taxi ride. To do this, we have to multiply. 20 x $1.85= $37.00.

Lastly, you have to find out how much the cost will be with the initial charge. To do this, we have to add. $37.00+$2.75=$39.75.

Given parallelogram ABCD, diagonals AC and BD intersect at point E. AE=11x−3 and CE=12−4x. Find the length of AC.

Oxana [17]

Answer:

AC=16 units

Step-by-step explanation:

The diagonals of a parallelogram bisect each other. It was given that diagonals AC and BD intersect at point E.

This implies that: $AE=CE$ .

We substitute the expression for x, we get:

$11x-3=12-4x$ .

Group similar terms to get:

$11x+4x=12+3$ .

$15x=15$ .

$x=1$

AC = 2(12-4x)

AC=2(12-4(1))

AC=2(8)

AC=16
