Answer:
Distance problems are word problems that involve the distance an object will travel at a certain average rate for a given period of time.
The formula for distance problems is: distance = rate × time or d = r × t.
Things to watch out for:
Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.
It would be helpful to use a table to organize the information for distance problems. A table helps you to think about one number at a time instead being confused by the question.

x+4.9=7.28 x= what is the answer
Answer:
2.38
Step-by-step explanation:
subtract 4.9 on both sides
x = 2.38
Step-by-step explanation:x + 4.9 = 7.28
x = 7.28 - 4.9
x = 2.38
The price-demand equation for gasoline is 0.3d + 4p = 80, where p is the price per gallon in dollars and d is the daily demand measured in millions of gallons. Write the demand d as a function of price What is the demand if the price is $ 8 per gallon?
Answer:
The demand d as a function of price is [tex]d=\frac{800}{3} -\frac{40p}{3}[/tex]
The demand if the price is $ 8 per gallon is 160 millions of gallons.
Step-by-step explanation:
You know that the price-demand equation for gasoline is 0.3d + 4p = 80
To write demand d as a function of price p, you must solve for or isolate demand d, remembering that:
All the terms that are multiplying on one side, go to the other side of the equality by dividing, and those that are dividing go to the other side of the equality by multiplying. The terms that are adding go to the other side of the equality by subtracting and those that are subtracting go to the other side by adding.So:
0.3d + 4p = 80
0.3d = 80 - 4p
[tex]d=\frac{80 - 4p}{0.3}[/tex]
[tex]d=\frac{80}{0.3} -\frac{4p}{0.3}[/tex]
[tex]d=\frac{800}{3} -\frac{40p}{3}[/tex]
The demand d as a function of price is [tex]d=\frac{800}{3} -\frac{40p}{3}[/tex]
To determine how much is the quantity demanded if the price is $ 8 per gallon, you simply plug that value into the previously determined expression and perform the corresponding calculations:
[tex]d=\frac{800}{3} -\frac{40*8}{3}[/tex]
[tex]d=\frac{800}{3} -\frac{320}{3}[/tex]
d= 160
The demand if the price is $ 8 per gallon is 160 millions of gallons.

One number is 28 less than another number. If the sum of the two numbers is 92, find the two numbers.
Answer:
The two numbers are 32 and 60.
Step-by-step explanation:
We can create two simultaneous equations to solve this problem using the information given in the question.
Let number 1 = x
Let number 1 = y
x = y - 28 -> ( 1 )
x + y = 92 -> ( 2 )
We can solve simultaneous equations using substitution or elimination. For this question, we will use substitution as it is the easier option.
Substitute ( 1 ) into ( 2 ):
x + y = 92 -> ( 2 )
( y - 28 ) + y = 92
2y - 28 = 92
2y = 120
y = 120 / 2
y = 60 -> ( 3 )
Substitute ( 3 ) into ( 1 ):
x = y - 28 -> ( 1 )
x = ( 60 ) - 28
x = 32
Therefore:
x = 32 , y = 60

Answer:
Which of the following graphs show a proportional relationship?
Choose all answers that apply:
The answer is A.
Using the proportional relationship concept, the graph of a straight line through the origin is seen in option (A).
So, option (A) is the correct option.
What is proportional relationship?"If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate."
In a proportional relationship, two quantities vary directly with each other.
We can represent relationships in several ways:
1. An equation in the form of y = kx , where k is the constant of proportionality or unit rate.
2. A graph of a straight line that passes through the origin.
3. A set or table of ordered pairs that show equivalent ratios.
4. A verbal description that describes a describe proportional relationship between two quantities.
Explanation for correct option:
According to the given options
The graph of a straight line through the origin is seen in option (A).
So, option (A) is the correct option.
Explanation for other options:
In option(B),
The graph of a straight line does not passes through the origin.
So, option (B) is not correct
In option(C),
Graph is not given
So, it is also not correct
Hence, the graph of a straight line through the origin is seen in option (A).
So, option (A) is the correct option.

Suppose you are asked to find the area of a rectangle that is 2.1-cm wide by 5.6-cm long. Your calculator answer would be 11.76 cm^2. Write the answer to two significant figures.
Answer:
12cm^2
Step-by-step explanation:
Area of a rectangle = Length × Width
Length = 5.6cm
Width= 2.1cm
Area of the rectangle = Length × Width
= 5.6cm × 2.1cm
= 11.76 centimeter square
Area of the rectangle = 11.76 centimeter square
Answer to two significant figures
There are two figures before the decimal and two figures after the decimal
Since, the question asked us to 2 significant figures, then we will focus on the two figures before the decimal point.

Point S is on line segment RT. Given ST = 3x
= 3x – 8, RT = 4x, and
RS = 4x 7, determine the numerical length of RT.
Answer:
RT = 20
Step-by-step explanation:
Given that,
Point S lies on the line segment RT.
We have, ST = 3x-8, RT = 4x and RS = 4x-7
It is clear that, RT = RS+ST
Putting the values, we get :
4x = 4x-7 + 3x-8
Taking like terms together,
4x-4x-3x = -7-8
-3x = -15
x = 5
Put the value of x in RT = 4x.
So,
RT = 4(5)
RT = 20
Hence, length of RT = 20.
