Answer:
5km
Step-by-step explanation:
The distance between two coordinates is expressed as;
D = √(x2-x1)²+(y2-y1)²
Marker 1 is at coordinate (2,1) and marker 2 at (-3,1)
Substitute into the formula
D = √(-3-2)²+(1-1)²
D = √(-5)²
D = √25
D = 5
Hence the distance between marker one and two is 5km

Answer:
18 will be the number of sides.
Step-by-step explanation:
As we know that the sum of exterior angles of a polygon is 360°.
The formula is:
The exterior angle of a polygon = 360 ÷ number of sidesAs each exterior angle of a regular polygon is 20°.
so putting the value exterior angle 20° in the formula
The exterior angle of a polygon = 360 ÷ number of sides
20 = 360 ÷ number of sides
20 = 360/number of sides
so the number of sides will be:
number of sides = 360/20
= 18
Therefore, 18 will be the number of sides.

7( x+3 ) < 5x + 13
Answer:
[tex]\boxed {x < -4}[/tex]
Step-by-step explanation:
Solve the following inequality:
[tex]7(x + 3) < 5x + 13[/tex]
Use Distributive Property:
[tex]7(x + 3) < 5x + 13[/tex]
[tex]7x + 21 < 5x + 13[/tex]
-Take [tex]5x[/tex] and subtract it from [tex]7x[/tex]:
[tex]7x + 21 - 5x < 5x - 5x + 13[/tex]
[tex]2x + 21 < 13[/tex]
Subtract both sides by [tex]21[/tex]:
[tex]2x + 21 - 21 < 13 - 21[/tex]
[tex]2x < -8[/tex]
Divide both side by [tex]2x[/tex]
[tex]\frac{2x}{2} < \frac{-8}{2}[/tex]
[tex]\boxed {x < -4}[/tex]

Step-by-step explanation:
Sebastián was saving $8.50 each week in order to have enough money for a phone that costs $122. If his father started him off with $25, write an inequality that can be used to determine the minimum number of whole weeks, w, Sebastián will need to save.
Step-by-step explanation:
122 - 25
97
y= 8.5x + 25
97/8.50 <
11.4 --> 12
x < 12
Answer:
25 + 8.50w ≥ 122
Step-by-step explanation:
Given that:
Amount saved per week = $8.50
Cost of phone = $122
Starting amount = $25
Minimum Number of whole weeks (w) Sébastien will need to save :
Starting amount + (weekly saving * number of weeks) ≥ 122
25 + 8.50w ≥ 122
8.50w ≥ 122 - 25
8.50w ≥ 97
w ≥ 97/8.50
w ≥ 11.4117
Number of whole weeks = 12

Answer:
C. The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, a = 3.
Step-by-step explanation:
Given the points (5, 15) and (-5, -15) are plotted using the equation y = a•x, this shows a proportional relationship between y and x.
Thus using any of the points, say (5, 15), x = 5, and y = 15, thus:
a = y/x = 15/5
a = 3
Therefore, the value of a, which is 3, is the number that the x-values, 5 and -5, are multiplied by to get the corresponding y-values, 15 and -15.
As we can see, if we multiply each of the x-values by 3, it will give us their corresponding y-values.

Generate an equivalent expression for:
5(2x+3y)
i kinda need this awnser asap also its for a flip grid so not to advanced
I WILL GIVE BRAINLIEST
Answer:
y = [tex]\frac{-2x}{3}[/tex]
Step-by-step explanation:
Distribute 5 to 2x and 3y by multiplying each by 5
10x + 15y
Isolate y to one side of the equation
15y=-10x
Divide each side by 15
y = [tex]\frac{-2x}{3}[/tex]
Answer:
5(2x + 3y) = 10x + 15y
Step-by-step explanation:
There is one particular way to find an equivalent expression which I am assuming is what the problem is looking for. When given a factored expression in the form of a binomial (two terms), by creating an equivilent expression, you can distribute the binomial inside the parenthesis factored by the coefficient 5. So 5(2x + 3y) = 5(2x) + 5(3y) = 10x + 15y.
5 is also the greatest common factor of 10x + 15y which is why this expression simplifies down to the equivilent expression 5(2x + 3y).
10x + 15y as a GCF is really the GCF of 10 and 15. What you do is individually split each number into all its possible factors(set of whole numbers that multiply to that number), and then find the factor that they both share.
For example, 10 has factors of 5, 2, 1, 10. And 15 has factors of 15, 1, 5, 3.
Notice how 5 appears in both.

The line of reflection is y=3
Step-by-step explanation:
John claims the following two expressions are equivalent.
- 215y - 3) = - 10y - 6
John's work in determining an expression equivalent to the first expression is shown below.
- 2/5y - 3)
= (-2x5y) - (-2x - 3)
= - 10y-6
Which statement explains why John's claim is incorrect?
He should have subtracted (-2 * 3) resulting in the expression–10y + 6.
He should have only multiplied 3 by -2 resulting in the expression 5y - 6.
He should have only multiplied Sy by -2 resulting in the expression-10y - 3.
He should have only multiplied 3 by -2 and subtracted (-2 * 3) resulting in the expression 5y + 6.
А.
В.
С.
D
Answer:
the answer is B. He should have only multiplied 3 by –2 resulting in the expression 5y – 6.
Step-by-step explanation:
In the given expressions, the reason for John's claim being incorrect would be:
B). He should have only multiplied 3 by –2 resulting in the expression 5y – 6.
Given,
The two expressions i.e. [tex](-215y - 3) = - 10y - 6[/tex]The mistake that John makes is that he multiplies the entire equation by -2 as shown in [tex]= (-2x5y) - (-2x - 3)[/tex] which makes it incorrect.In order to rectify this mistake, only 3 was suppossed to be multiplied by -2 so that the outcome comes out as [tex]5y - 6[/tex].Thus, option B is the correct answer.

The cost y (in dollars) to spend an evening bowling is proportional to the
number of games x that are bowled.
It costs $16 to bowl 4 games.
5. Write an equation that represents the situation.
6. How much does it cost in dollars) to bowl 6 games?
Answer:
y = 4x
Bowl 6 games cost $24
Step-by-step explanation:
Proportional Relationship
We have a situation where the cost y in dollars to spend an evening bowling is proportional to the number of games x bowled.
A proportional relationship is written with the equation:
y = k.x
The value of k will be determined by using the given information: 4 games bowled cost $16, thus:
16 = k.(4) = 4k
Solving:
k = 16 / 4 =4
Thus, the function is:
y = 4x
x=6 games bowled cost:
y = 4*6
y = $24
Bowl 6 games cost $24
What figure will result when the triangle is rotated around RE?
Answer:
The figure will result is cone ⇒ B
Step-by-step explanation:
When a right triangle is rotated about its vertical leg 360°, then it formed a cone its radius is the horizontal leg of the triangle and its height is the vertical lege of the triangle
In the given figure
∵ Triangle TRE is a right triangle
∴ The horizontal leg is RE
∴ The vertical leg is TR
∵ The triangle is rotated around the horizontal leg RE 360°
∴ It formed a cone its radius = TR and its height = RE
∴ The figure will result is the cone
