The inequality that represents the situation in terms of x hours is; B: 7.5x ≤ 60
How to solve Inequality Word Problems?We are told that for every hour x that Eva’s electric car charges, she can drive the car 7.5 miles. Eva needs to drive at least 60 miles tomorrow.
Now, 7.5 miles represents the speed per hour and we know that formula for distance is;
distance = speed * time
Since she wants to drive at least 60 miles tomorrow, then it means the number of miles must be greater than or equal to 60. Thus, the inequality that models the given situation is;

Christine went shopping and bought each of her ten nephews a gift, either a video costing $14.95 or a CD costin $16.88. She spent $161.08 on the giftsHow many videos and how many CDs did she buy?
Therefore , the solution to the given problem of linear equation comes out to be we bought 6 videos and 3 CDs.
Define a linear equation.The term "linear" refers to any function that has the algebraic form y=mx+b. m is the y-intercept, while B is the slope. The previous sentence contains a two-variable linear equation since both y and y are factors. Equations involving two variables are called bivariate equations. y + z = 2 and 3z - 6 + x = 3 are two of the many applications for linear equations. The equation y=mx+b, where m stands for the slope and b for the y-intercept, is referred to as a linear equation. The formula is Y=mx+b, where m denotes the inclination and b the y-intercept.
Here,
A collection of equations will be constructed.
Let V = the number of videos purchased.
C will stand for the quantity of purchased CDs.
Since there are eight nephews in all, and each nephew received either a video or a CD, the sum of the numbers of movies and CDs is nine.
So V + C = 9.
We are also aware of how much each CD and film cost and how much money was wasted.
So 14.95V + 16.88C = 140.34
Here, let's experiment with substitution.
Let's just solve for V since it doesn't matter whichever variable we do it for. V = 9 - C
Therefore, replace "V" in the second equation with "9-C," and the result will be 134.55 - 14.95C + 16.88C = 140.34 1.93C = 5.79 C = 3
You can add C = 3 straight into either of the original equations, though I believe I know which one is simpler for you.
V + 3 = 9
V = 6
So we bought 3 CDs and 6 videos.
Therefore , the solution to the given problem of equation comes out to be we bought 6 videos and 3 CDs.

'I decided to add 8.6 to my number then multiply the result by 3, After that I subtracted 1.9 then doubled the result. The answer is 59.2'
What number was Savannah first thinking of?
Answer:
The number was 1.9------------------------------------------
Let the number be x.
Set up equation to reflect all the operations:
((x + 8.6)*3 - 1.9)*2 = 59.2Solve it in below steps:
((x + 8.6)*3 - 1.9)*2 = 59.2(x + 8.6)*3 - 1.9 = 59.2/2 (x + 8.6)*3 - 1.9 = 29.6(x + 8.6)*3 = 29.6 + 1.9 (x + 8.6)*3 = 31.5x + 8.6 = 31.5/3 x + 8.6 = 10.5x = 10.5 - 8.6 x = 1.9Which points are reflections of each other across both axes?(–2, 8) and (2, –8)(–7, –1) and (–7, 1)(5, –6) and (–5, –6)(4, –3) and (–3, 4)
The points (–2, 8) and (2, –8) are reflections of each other across both axes. This can be seen by taking their coordinates and plugging them into the reflection formula, which is (x, y) → (–x, –y).
When we plug in the coordinates for the first point, we get (–2, 8) → (–(–2), –(8)) = (2, –8). This is the coordinates of the second point, so they are reflections of each other.
The points (–7, –1) and (–7, 1) are also reflections of each other across both axes. Using the same reflection formula, we get (–7, –1) → (–(–7), –(–1)) = (7, 1), which are the coordinates of the second point.
The points (5, –6) and (–5, –6) are reflections of each other across both axes. Applying the reflection formula, we get (5, –6) → (–(5), –(–6)) = (–5, 6), which are the coordinates of the second point.
Finally, the points (4, –3) and (–3, 4) are reflections of each other across both axes. Using the reflection formula, we get (4, –3) → (–(4), –(–3)) = (–4, 3), which are the coordinates of the second point.

What is an inequality?
In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”. But to compare the values, whether it is less than or greater than, different inequalities are used
Inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol. The expressions on both sides of an inequality sign are not equal. It means that the expression on the left-hand side should be greater than or less than the expression on the right-hand side or vice versa
If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then the relation is called an inequality.
From the question,
x>3 (x should be greater than 3) means the the value of x is more or greater than 3, that is, x is 4,5,6,...

Find two consecutive positive integers such that the square of the larger integer is 19 more than 9 times the smaller integer define your variables and write an equation HURRY HELP PLEASE SHOW STEPS
Answer:
9 and 10
Step-by-step explanation:
x = 1st positive integer
x+1 = 2nd positive integer
Solve for both x and x+1(x+1) is the next positive integer after x (Ex. 3 aka 2+1 is next integer after 2).
Larger Integer: x+1 ==> being squared
Smaller Integer: x ==> being multipled by 9
9x + 19 = (x+1)^2 ==> the square of (x+1) is 19 more that 9 multiplied by x.
9x + 19 = (x+1)(x+1) ==> simplify
9x + 19 = x(x+1) + 1(x+1) ==> distribute (x+1) to x and 1.
9x + 19 = (x*x + 1*x) + (1*x + 1*1)
9x + 19 = x^2 + x + x + 1 ==> simplify
9x + 19 = x^2 + 2x + 1
19 = x^2 - 7x + 1 ==> subtract 9x on both sides
Make one side of the equation equal to 0 so you can factor the equation:
0 = x^2 - 7x - 18 ==> subtract both sides by 19
0 = x^2 + 2x - 9x - 18 ==> 2x - 9x = -7x and 2 * (-9) = -18
0 = x*x + 2x - 9x - 18
0 = x(x + 2) - 9(x + 2) ==> factor
0 = (x - 9)(x + 2)
x - 9 = 0 x + 2 = 0
x = 9 x = -2
Out of x = 9 and x = -2, only x = 9 is positive.
Hence, x = 9 and x+1=10.
Hence, the answers are 9 and 10.

Where is 0 latitude and 0 longitude?
0 degree latitude and 0 degree longitude is at equator
Longitudes: The vertical lines running north-south, join the two poles. They are called the meridians of longitude. They are spaced farthest apart at the equator and converge at a point at each pole.
Horizontal lines called latitudes are used to measure distances north or south of the equator. Vertical lines known as longitudes are used to determine the west or east of the meridian in Greenwich, England. Latitude and longitude work together to help cartographers, geographers, and others find specific locations on the globe.
What is the uses of latitude?
Any location's distance from the equator may be determined using its latitude, which is based on its degree. We can locate any point on Earth using longitude and latitude. The GPS or Global Positioning System uses these coordinates.
The grid system that enables us to locate absolute or precise places on the surface of the Earth is made up of latitude and longitude. Latitude and longitude can be used to pinpoint certain locations. Landmark identification also benefits from knowledge of latitude and longitude.

∆ABC and ∆EFD are congruent by the ASA criterion as segment AC and segment DE has single tick mark, angle A and angle E has single tick marks on arc and angle C and angle D has double tick marks on arc.
The ASA (Angle-Side-Angle) criterion states that if two triangles have two angles and the included side congruent (identical), then the two triangles are congruent.
In this case, both triangles ABC and DEF have two angles congruent (angle A and angle E, and angle C and angle D), and the included side (segment AC and segment DE) congruent. Therefore, by the ASA criterion, the two triangles ABC and DEF are congruent.
To be more precise Angle A and angle E has single tick marks on arc which means both angles are congruent and angle C and angle D has double tick marks on arc which means both angles are congruent. As we know, if two triangles have corresponding parts congruent, the two triangles are congruent.
