Answer:
$90
Step-by-step explanation:
Let's consider the remaining money. If x represents the amount Arlene started with, then the remaining amounts are ...
after first store: x -(0.4x +4) = 0.60x -4
After spending 50% of her money, the amount remaining will be 1-50% = 50%. Then spending 5 more dollars reduces the amount remaining by another 5.
after second store: (0.60x -4)(0.50) -5 = 0.30x -2 -7 = 0.30x -7
After spending 60% of her money, the amount remaining will be 1-60% = 40%. Then spending 6 more dollars reduces the amount remaining by another 6.
after third store: (0.30x -7)(0.40) -6 = 0.12x -2.80 -6 = 0.12x -8.80
This is reported to be $2, so we have ...
0.12x -8.80 = 2
0.12x = 10.80
x = 90
Arlene started shopping with $90.
_____
Check
At the first store, Arlene spent 0.40×$90 +$4 = $40, so she had $90-40=$50 remaining.
At the second store, Arlene spent 0.50×$50 +$5 = $30, so she had $50-30=$20 remaining.
At the third store, Arlene spent 0.60×$20+$6 = $18, so she had $20-18 =$2 remaining.

Answer:
1:2
Step-by-step explanation:
because there are 9 stars and 18 squares giving you 9:18 but when you simplyfi you get 1:2
Answer: 9:18
Step-by-step explanation:
Count the amount of stars which is 9, then count the amount of circles which is 18. So therefore the answer would be 9:18
The distance between X and Y is 6 1/2 units. Which number could represent the point Y?
Answer:
[tex]\huge\boxed{\sf 3.5}[/tex]
Step-by-step explanation:
Distance = [tex]\sf 6 \frac{1}{2} \ units = 6.5 \ units[/tex]
Here X is -3
So,
Point Y = -3 + 6.5 = 3.5
[tex]\rule[225]{225}{2}[/tex]
Hope this helped!
~AH1807Answer:
B
Step-by-step explanation:
so we know x is -3
we also know that the number has to be 6.5 units away from -3
so, -3 plus 6.5 is 3.5
-3 minus 6.5 is -9.5
Either 3.5 or -9.5 would work but 3.5 is the only listed option, so the answer is B

Eugene ate 20% of the Christmas cookies his
grandmother made. If he ate 8 cookies, how
many are left?
Answer:
There are 32 cookies left
Step-by-step explanation:
There are c cookies when we started
c* 20% = 8 cookies
Change to decimal form
c * .20 = 8
Divide each side by .2
c * .2 / .2 = 8/.2
c =40
There are 40 cookies when we started
40 -8 = 32
There are 32 cookies left

m – 9 + m + 3 what is the awnser
Answer:
2m - 6
Step-by-step explanation:
Combine the two m's in the equation to get 2m in which each m is 1. Combine -9 and 3 together to get -6 since you are adding 3 to -9. You should get 2m-6 as your final answer.

I am thinking of a number, let's call it x . If I increase twice my number by 5, the result is the same as if I triple my number and subtract 1. Use the 4-step process to write and solve an equation to find my number. Make sure to answer in a sentence.
Answer: 6
Step-by-step explanation:
Let the number be x
If I increase twice my number by 5, the result is the same as if I triple my number and subtract 1. This can be formed into an equation as:
(2 × x) + 5 = (3 × x) - 1
2x + 5 = 3x - 1
5 + 1 = 3x - 2x
x = 6
The number you are thinking of is 6

Madelyn has completed 10/20 problems. Will has completed 80% of the problems. Adam has finished 3/4 of them. Who has finished the most
Answer:
Will has completed the Most.
Step-by-step explanation:
Madelyn has completed 50%
Adam has completed 75%
Will has completed 80%
I hope this helps!!! Please Mark Me Brainliest!!!!!!
Answer: Will
Step-by-step explanation:
Madelyn = 50%. 10/20 = 50%, because 10/20 is half, and 50% is half
Will = 80%
Adam = 75%. 3/4 x 25 = 75/100, which equals 75%.
So in conclusion, Will has finished the most problems, 2nd is Adam, and last is Madelyn.
Hope this helps!

Rhombus JKLM with vertices J(-4,7), K(0,8), L(-1, 4), and M(-5,3): (x, y) ------> (x + 2, y - 2)
Answer:
J'(-2, 5), K'(2, 6), L'(1, 2) and M'(-3, 1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, rotation, dilation and translation.
Translation is the movement of a point either up, down, left or right on the coordinate plane. If a point A(x,y) is translated a units right and b units up, the new point is at A'(x + a, y + b) while a point A(x,y) is translated a units left and b units down, the new point is at A'(x - a, y - b).
Rhombus JKLM has vertices at J(-4,7), K(0,8), L(-1, 4), and M(-5,3). If a transformation of (x, y) ------> (x + 2, y - 2) is done, i.e. 2 units right and 2 units down, the new points would be at:
J'(-2, 5), K'(2, 6), L'(1, 2) and M'(-3, 1)

❁ Question : Simplify :
[tex] \sf{( {x}^{a} ) ^{b - c} \times ( {x}^{b} ) ^{c - a} \times ( {x}^{c} )^{a - b}} [/tex]❁ Solution :
First , Use power law of indices.
Remember : If [tex] \sf{ {a}^{m} }[/tex] is an algebraic term , then
[tex] \sf{( {a}^{m} ) ^{n} } = {a}^{m \times n} = {a}^{mn} [/tex] , where m and n are positive integers.
➝ [tex] \sf{ {x}^{a(b - c)} \times {x}^{b(c - a)} \times {x}^{c(a - b)}} [/tex]
➝ [tex] \sf{ {x}^{ab - ac} \times {x}^{bc - ba} \times {x}^{ca - cb}} [/tex]
Now , Use product law of indices :
Remember : If [tex] \sf{ {a}^{m} }[/tex] and [tex] \sf{ {a}^{n}} [/tex] are the two algebraic terms , where m and n are the positive integers then [tex] \sf{ {a}^{m} \times {a}^{n} = {a}^{m + n}} [/tex]
➝ [tex] \sf{ {x}^{ab - ac + bc - ba + ca - cb}} [/tex]
Since two opposites adds up to zero , remove them :
➝ [tex] \sf{ {x} \: ^{ \cancel{ab} \: - \cancel{ac} \: + \cancel{bc} \: - \cancel{ba} \: + \cancel{ca} \: - \cancel{cb} } }[/tex]
➝ [tex] \sf{ {x}^{0} }[/tex]
Use Law of zero index
Remember : If [tex] \sf{ {a}^{0}} [/tex] is an algebraic term , where a ≠ 0 , then [tex] \sf{ {a}^{0} = 1}[/tex]
➝ [tex] \boxed{ \sf{1}}[/tex]
And we're done !

If Danny gains 40 yards on the football field and then looses 15, What was the end result?
Answer:
25 yards
Step-by-step explanation:
Subtract 15 from 40.
Hope this helped :)
Answer:
25 yards
Step-by-step explanation:
Arithmetics
Imagine a straight line divided into 1-yard marks.
Danny runs for 40 marks and locates at mark 40.
He later loses 15 yards and his new position is 40 - 15 = 25 yards
Therefore, the end result is that Danny is at the 25-yard mark.
A ball is dropped from a height of 50 feet. The function f(x) = 50(0.6)x gives the height in feet of feet of each bounce, where x is the bounce number. What is the height of the third bounce to the nearest tenth of a foot?
Answer:
The height of the third bounce is 10.8 feet
Step-by-step explanation:
Let us solve the question
∵ A ball is dropped from a height of 50 feet
∵ The function f(x) = 50[tex](0.6)^{x}[/tex] gives the height in feet of each bounce
∵ x is the bounce number
∵ We need to find the height of the third bounce
∴ x = 3
→ Substitute x by 3 in the function above
∵ f(3) = 50(0.6)³
∴ f(3) = 50(0.126)
∴ f(3) = 10.8
∴ The height of the third bounce is 10.8 feet
