11 = 5x - 2
Can someone help me
Answer:
x=13/5
Step-by-step explanation:
To solve for x you must isolate the variable.
Start with the original equation,
11=5x-2, then add 2 to both sides (addition PoE)
13=5x, next divide both sides by 5 (division PoE)
13/5=x or 2.6

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in the simplest form 15,11,7
Step-by-step explanation:
the sequence is arithmetic due to the common difference that is equal
d=11-15=7-11=-4
a(n) = a1 +(n-1)d
a1=15
Then :
a(n) = 15+(n-1)-4
hope this helps
Answer: I think the answer is arithmetic sequence and the common ration is equal to 1/3.

What is the percent of change from 100 to 150?
Answer:
50%
Step-by-step explanation:
The percentage change from 100 to 150 is 50%
Calculated as follows:
150 - 100 = 50
50 / 100 * 100
= 50%
The correct answer to the given question is 50%
Difference of 150 and 100 will be divided by the base number which is 100 and to calculate percentage the answer is multiplied by 100 which makes 50%.

What is the slope of the line through (-7,-2)(−6,7)
Answer:
9
Step-by-step explanation:
The slope of the line is found by
m = ( y2-y1)/(x2-x1)
= ( 7 - -2)/( -6 - -7)
= ( 7+2) (-6+7)
= 9/1
=9

Which of the following names an angle in the drawing?
Answer: B and C Is my guess
Step-by-step explanation:
Answer:
B and C
Step-by-step explanation:
A) There is no line between E and D, so that can't be the name of an angle.
B) Angle ACB is all connected and is an obtuse angle.
C) Angle FCB is all connected even though you have to go through point E. If you start outward going in then technically it can be seen as E being a point on line F. However, if the answer was angle ECB that would also be correct.
D) Angle DEB has no connecting lines.

A 0.45 kg soccer ball changes its velocity by 20.0 m/s due to a force applied to it in 0.10 seconds. What force was necessary for this change in velocity? _______N
Answer: the answer is 90N
Answer:
90 N
Step-by-step explanation:
Mass of ball = 0.45 kg
Change in velocity = 20.0 m/s
Time = 0.10 seconds
Force required for change =?
Since force refers to the change in momentum per unit time, hence
Force = Momentum / Time
i.e Force = Mass x (change in velocity / time)
Force = 0.45kg x (20.0m/s /0.10second)
= 0.45kg x (200 m/s^2)
= 90N
GEOMETRY A rectangle has side lengths of (3x + 6) inches and (2x - 4) inches. Write an expression to represent the perimeter of the rectangle. Then find the value of x if the perimeter is 94 inches.
Answer:
x=9
Step-by-step explanation:
Step one:
given data
lengths =(3x + 6) inches and
Width= (2x - 4) inches.
Required:
the expression for the perimeter of the rectangular geometry
Step two:
We know that the expression for the perimeter is
P= 2L+2W
P=2(3x + 6)+2(2x - 4)
open bracket
P=6x+12+4x-8
collect like terms
P=10x+4
Step three:
when P= 94 we want to find x
94=10x+4
94-4=10x
90=10x
divide by 10
x=90/10
x= 9

Vanessa bought a laptop at a 20% discount. The original price of the laptop was $275.00. How much money did Vanessa save?
Answer:
$55.00
Step-by-step explanation:
20% of 275 is 55. Meaning she saved 55 dollars.
Answer:
Vanessa saved $55, and she only had to pay $220.
Step-by-step explanation:
First we need to convert 20% into a decimal, 0.20.
Now we need to multiply 275 and 0.20.
275 × 0.20 = 55
275 - 55 = 220

Sam is selling homemade cookies to raise money for charity. Each cookie sells for $.50. Sam spent $90 on baking supplies and each cookie will cost $.25 to me. How many cookies does Sam need to sell before making a profit?
9514 1404 393
Answer:
360
Step-by-step explanation:
Sam obtains a "contribution margin" of $0.50 -0.25 = $0.25 per cookie. That will cover the cost of baking supplies when he sells ...
$90 / ($0.25/cookie) = 360 cookies
Sam needs to sell 360 cookies before he can start making a profit.
_____
If you like, you can find Sam's break-even point by equating revenue and cost. The is the number of cookies Sam must sell for a profit of 0, that is, for non-negative profit.
P = R - C
0 = R - C
R = C
0.50n = 90 +0.25n
0.25n = 90 . . . . subtract 0.25n
n = 90/0.25 = 360 . . . .divide by the coefficient of n

What is the area of this polygon?
Step-by-step explanation:
The area of the polygon is 51cm².
Answer:
To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem . Here is what it means: Perimeter = the sum of the lengths of all the sides Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side

8/15 (-2/3)
Answer:
-16/3
Step-by-step explanation:
First, you will need to make both of the denominators the same number. Lucky for you, 3 and 15 both have the GCF of 3. To get 15 from 3, you will need to multiply 3 by 5.
When you multiply the denominator of -2/3 by 5, you will have to do the same to the top. Therefore, you will have to multiply -2 by 5 as well.
Now, you are left with 8/15 (-10/15).
Now that the denominators are the same, you can multiply. You only multiply the numerator, the denominator stays the same (15). 8 * -10 = -80.
You've been left with -80/15, but it's not in it's simplest form. You can easily divide the numerator and denominator by 5. The numerator is now -16. The denominator is now 3.
Your answer is -16/3 because you cannot simplify further.

If f\left(x\right)=\mid x\midf ( x ) =∣ x ∣, then what is the new function g\left(x\right)g ( x ) when f\left(x\right)f ( x ) is translated 3 units down, followed by a vertical stretch of 2? Group of answer choices
Answer:
[tex]g(x) = 2 (|x| - 3)[/tex]
Step-by-step explanation:
Given
[tex]f\left(x\right)=\mid x\mid[/tex]
Translation = 3 units down
Vertical stretch of 2 to give g(x)
Required
[tex]g\left(x\right)[/tex]
3 units down translation
A function is translated down as follows:
[tex]h(x) = f(x) - k[/tex]
Where k is the number of units.
So:
[tex]h(x) = f(x) - k[/tex]
[tex]h(x) = |x| - 3[/tex]
Vertical stretch of 2
A function is vertically stretched as follows;
[tex]g(x) = ah(x)[/tex]
Where a is the units stretched.
In this case:
[tex]a = 2[/tex]
So:
[tex]g(x) = ah(x)[/tex]
[tex]g(x) = 2 * (|x| - 3)[/tex]
[tex]g(x) = 2 (|x| - 3)[/tex]
If the ratio of children to adults is 5:7 and there are 100 children at an arts festival, how many adults are in attendance?
Answer:
140 adults.
Step-by-step explanation:
5:7 Ratio. 100 Children, so if we want the adults we want to reverse the ratio, 100 x 7/5 = 140.
140 Adults.
To check our work we can see if the fractions are the same, so divide 5/7 and 100/140 and you'll see they both have the same result.
