(2) Parv has a $50 gift card. He uses the gift card to buy a pack of games
for $9.99. He also wants to buy some movies (n). Each movie costs
$3.99. Which inequality describes how many movies Parv can buy?
Answer:
$50 - $9.99 = $40.01
$40.01 ÷ $3.99 = 10
so the answer is 10
Step-by-step explanation:
if thats not whats being asked sorry
Inequality shows a relationship between two numbers or two expressions.
The inequality describes the number of movies Parv can buy.
9.99 + 3.99x ≤ 50
Where x is the number of movies.
The number of movies Parv can buy is 10.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal= ≥
We have,
Gift card = $50
Cost of a pack of games = $9.99
Cost of each movie = $3.99
x = number of movies
The inequality describes the number of movies Parv can buy.
9.99 + 3.99x ≤ 50
Where x is the number of movies.
Solve for x.
9.99 + 3.99x ≤ 50
Subtract 9.99 on both sides.
3.99x ≤ 50 - 9.99
3.99x ≤ 40.01
Divide both sides by 3.99
x ≤ 40.01/3.99
x ≤ 10
This means the number of movies Parv can buy is 10.
We can cross-check.
9.99 + 3.99 x 10 ≤ 50
9.99 + 39.9 ≤ 50
49.89 ≤ 50
Thus,
The number of movies Parv can buy is 10.

What type of linear equation is the following?
x + 2y = 200
1) Standard Form
2) Slope-Intercept Form
3) Point-Slope Form
4) Horizontal Form
Which equation describes a line that passes through the point (-6, 2) and is parallel to
the line represented by 2y - 4x = 10?
Anyone know??
Answer:
y = 2x +14
Step-by-step explanation:
2y - 4x = 10
=> 2y = 4x + 10
=> y = 2x + 5
↑ the slope of this equation
parallel lines have the same slope, thus, the equation in the 4 options must have the same slope: 2.
plug in point (-6, 2) & the slope "2" into the equation: y = ax + b to find "b."
=> 2 = -6(2) + b
=> b = 14
plug in the slope "2" and the y-intercept(or b) "14" into the equation: y = ax + b
=> y = 2x +14

A car used 16 gallons of gasoline and traveled a total distance of 460 miles. The car's fuel efficiency is 30 miles per gallon on the highway and 25 miles per gallon in the city. How many gallons of gasoline were used on the highway.
Answer:
12 gallons
Step-by-step explanation:
Total gallons = 16 gallons
Total distance = 460 miles
Fuel efficiency in the highway = 30 miles per gallon
Fuel efficiency in the city = 25 miles per gallon
Let
h = gallons of gasoline were used on the highway.
460 = 30h + 25(16 - h)
460 = 30h + 400 - 25h
460 - 400 = 30h - 25h
60 = 5h
h = 60/5
h = 12 gallons
12 gallons of gasoline were used on the highway.
A van travelled at an average speed of 65 km/hr from town a. 35 minutes later, a car started from town A and drove along the same route as the van. if the car caught up with the van after travelling a distance of 130 km, find the average speed of the car in km/hr
The average speed of the car for the given distance is 91.97 km/hr.
What is speed and velocity?While both speed and velocity are indicators of how quickly an object is travelling, they serve different purposes. The distance travelled in a given amount of time, independent of direction, is referred to as speed, which is the magnitude of the velocity vector. In contrast, velocity is a vector quantity that accounts for both speed and direction. It is measured in units of distance per unit of time in a particular direction and is defined as the rate of change of position of an item with regard to a frame of reference.
Given that, a car started 35 minutes later that is it started after:
35 minutes = 35/60 = 0.5833 hours
Now the distance is given as:
distance = speed x time
Now, for speed = 65 km/hr:
distance = 65t
For the car the time is (t - 0.5833) thus:
distance = speed x time
130 = speed x (t - 0.5833)
Now for speed we have:
30 = s x (t - 0.5833)
130 = st - 0.5833s
130 + 0.5833s = st
130/s + 0.5833 = t
Now, substituting the value of t in the equation of the van we have:
distance = 65t
distance = 65(130/s + 0.5833)
130/s + 0.5833 = distance/65
130/s + 0.5833 = distance/65
130/s + 0.5833 = 130/65
130/s + 0.5833 = 2
s = 91.97km/hr
Hence, the average speed of the car for the given distance is 91.97 km/hr.

This is a scale drawing of a flag. The scale factor of a drawing to the actual flag is represented by the ratio 1:18. What is the area, in
square inches, of the actual flag?
Answer:
648 sq. in.
Step-by-step explanation:
The ratio of the flag is 1:18 and the question asks for the area of the flag.
To find the actual flag size, you got to multiply the width by 18.
Then you must multiply the length by 18.
A= LxW
A=36 x 18
A= 648 sq. in.
Therefore, the area of the actual flag is 648 sq. in.

Step-by-step explanation:
This is a circle.
The generic equation of a circle is
(x-h)^2+ (y-k)^2 = r^2
where (h,k) is the center and r is the radius
The center of the circle is at the origin which is (0,0)
The radius is 7
(x-0)^2+(y-0)^2 = 7^2
x^2+y^2 = 49
Answer:
[tex] \displaystyle {x}^{2} + {y}^{2} = 49[/tex]
Step-by-step explanation:
we are given a circle
we want to figure out the equation of the circle
remember that,
[tex] \rm \displaystyle E _{c} : (x - {h)}^{2} + (y - k {)}^{2} = {r}^{2} [/tex]
(h,k) are the centre of the circle
we can clearly see that the centre of the circle is (0,0) and the redious is 7 units
thus substitute:
[tex] \displaystyle (x - {0)}^{2} + (y - 0{)}^{2} = {7}^{2} [/tex]
further simplification is needed:
[tex] \displaystyle {x}^{2} + {y}^{2} = 49[/tex]

Total cost of pay for the lunch will be $96.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The cost of lunch = $75
Sales tax = 8%
Tip = 20%
Now,
The cost on sales tax = 8% of $75
= 8/100 x 75
= $6
Thus, The cost on sales tax = $6
And, The cost for tip = 20% of $75
= 20/100 x 75
= $15
Thus, The cost for tip = $15
So, Total cost to pay for lunch = $75 + $6 + $15
= $96
Thus, Total cost of pay for the lunch will be $96.
