-x = 28
x = -28
Step-by-step explanation:
Answer: -1/4*-28=7
x=-28
Step-by-step explanation:
First, do -1/4 and you should get-0.25 as your answer .
Next, do 7/-0.25
Last, check your answer and to do so simply multiply -1/4*-28 and you should get 7 as your final answer.

Is one of many solutions to the inequality:
X - 3y<1
True or false?
Answer:
False
Step-by-step explanation:
lets find out..
x - 3y < 1.....check (2,-1)....x = 2 and y = -1
now we sub
2 - 3(-1) < 1
2 + 3 < 1
5 < 1.......so is 5 less then 1 ? NO, it is not...so (2,-1) IS NOT a solution

Answer:
20%.
Step-by-step explanation:
That is (60 - 50) / 50
= 10/50
= 1/5
To convert to a percent we multiply by 100:
= 20%.
I think it will be 10% because you invited 50 right? And 60 atended or was it 60 and 50 atended? Well either way I think it’s 10%

What is the exact value of cos (67.5° )?
The exact value of cos(67.5°) is found using half-angle identities in trigonometry, which leads to the solution √(2 - √2)/2.
Explanation:To find the exact value of cos (67.5°), we can use the half-angle identity for cosine which states that cos(θ/2) = ± √ ((1+cosθ)/2). In this case, to find the cosine of 67.5 degrees, we effectively need to calculate the half-angle of 135 degrees.
Thus, cos(67.5°) = cos(135°/2) = √ ((1+cos135°)/2) = √ ((1 - √2/2)/2). This further simplifies to √(2 - √2)/2.
This is because the cosine of 135 degrees equals -√2/2 (as it's in the second quadrant where cosine is negative).
Therefore, the exact value of cos(67.5°) is √(2 - √2)/2.

Find the value of the y-intercept of the line whose equation is 5x - 3y = -12.
To find the y-intercept, rewrite the equation of the line in slope-intercept form:
Slope-intercept form: y = mx + b (b is the y-intercept)
This is how you get your equation in slope-intercept form:
5x -3y = -12
-3y = -5x - 12
-3y/-3 = (-5x -12)/-3
y = (5/3)x + 4

what is emigration?Emigration is the act of leaving one's country or region to live in another. It is a type of migration, which refers to the movement of people from one place to another. Emigration is different from immigration, which is the process of entering a new country or region to live there permanently.
The Puritans were a group of English Protestants in the 16th and 17th centuries who sought to "purify" the Church of England from what they saw as Roman Catholic practices.
They faced persecution and discrimination in England, which led many of them to emigrate to America in search of religious freedom.
The most well-known group of Puritan emigrants to America were the Pilgrims, who established the Plymouth Colony in Massachusetts in 1620.

Jenna and Callie collect stamps. Jenna has 20 less than twice the number of stamps that Callie has. Write an expression that represents the number of stamps that Jenna has.
The expression that represents the number of stamps that Jenna has is 2x - 20
Step-by-step explanation:
Let us revise some algebraic expressions
a is 5 more than b ⇒ a = b + 5a is 3 less than b ⇒ a = b - 3a is twice b ⇒ a = 2 bThe sum of a and b ⇒ a + bThe difference of a and b ⇒ a - bThe quotient of a and b ⇒ a ÷ bThe product of a and b ⇒ a × b∵ Jenna and Callie collect stamps
∵ Jenna has 20 less than twice the number of stamps that Callie has
- Assume that Callie has x stamps, that means to find the number
of stamps of Jenna multiply x by 2 and subtract 20 from the product
∵ Callie has x stamps
∵ Twice means × 2
∴ Jenna has = 2(x) - 20
∴ Jenna has = 2x - 20
The expression that represents the number of stamps that Jenna has is 2x - 20

The area of a rectangle is 17 1/2 in and it’s shorter side is 3 1/2in.draw a diagram that shows this information. What is the length of the longer side
Answer: 5
Step-by-step explanation:
17 1/2 is equal to 17.5
3 1/2 is equal to 3.5
Since 17.5 is the area, you must divide by 3.5, which equals 5
To find the length of the longer side of a rectangle with an area of 17 1/2 square inches and a shorter side of 3 1/2 inches, divide the area by the width to get the length. The length of the longer side is 5 inches.
Explanation:The question is asking how to find the length of the longer side of a rectangle given that the area of the rectangle is 17 1/2 square inches and one of the shorter sides is 3 1/2 inches. To find the length of the other side, which we will call length, use the formula for the area of a rectangle which is area = length × width. Since the area and width (shorter side) are known, the equation can be set up as follows:
17 1/2 = length × 3 1/2To find the length, divide the area by the width:Length = (17 1/2) / (3 1/2)Convert mixed numbers to improper fractions:Length = (35/2) / (7/2)Multiply by the reciprocal of the divisor:Length = (35/2) × (2/7)Simplify the fractions:Length = 5Therefore, the length of the longer side of the rectangle is 5 inches.

Two cars are 190 miles apart and travel toward each other along the same road. They meet in 2 hours. One car travels 5 miles per hour faster than the other car. What is the average speed of each car?
The speed of slower car is 45 mph and faster car is 50 mph.
Step-by-step explanation:
Given,
Distance covered by both cars = 190 miles
Time taken by both of them = 2 hours
Let,
x be the speed of slower car.
Speed of faster car = x+5
Combined speed = x+x+5 = 2x+5
We know that;
Distance = Speed * Time
[tex]190=(2x+5)*2\\190=4x+10\\4x=190-10\\4x=180\\[/tex]
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{180}{4}\\x=45[/tex]
Speed of slower car = 45 miles per hour
Speed of faster car = 45+5 = 50 miles per hour
The speed of slower car is 45 mph and faster car is 50 mph.

The problem given is a relative speed problem in mathematics. By solving the equation, we find that the slower car travels at 45 mph and the faster car travels at 50 mph.
Explanation:This is a
problem of relative speed
in
mathematics
. Let's consider the speed of the slower car as 'x' miles per hour. The faster car is travelling 'x+5' miles per hour. Since they are moving towards each other, the sum of their speeds equals the total distance divided by the total time, that is (x + (x + 5)) = 190/2. Simplifying the equation, we get 2x + 5 = 95. Solving further, we get x = 45 miles per hour. Therefore, the slower car is travelling at 45 mph and the faster car is travelling at 50 mph.
