It takes Adi 2 hours to drive from home to her office and 3 hours if she drives 15 mph slower. What is the distance between Adi'

Solnce55 [7]

Answer:

90 miles

Step-by-step explanation:

Let ori. speed = z

distance = speed × time

= z × 2

= 2z miles

distance = (z - 15) × 3

= (3z - 45)miles

2z = 3z - 45

z = 45mph

distance = 45 × 2

= 90 miles

distance = (45-15) × 3

= 90 miles

You make 35 postcards and sell them for D dollars each. The table to the right shows the predicted sales for different prices, D

Ad libitum [116K]

The representations are:

D represents the price of each postcard
35 - 5D represents the number of postcard sold
D(35 - 5D) represents the income from the sales

<h3>What are expressions?</h3>

Expressions are mathematical statements that contain all of the followings

Numbers
Mathematical operator
Variables

The expression is given as:

$D(35 - 5D)$

From the question, we understand that:

D represents the price of each postcard

D(35 - 5D) represents the income from the sales

The above highlights mean that: 35 - 5D represents the number of postcard sold
