John has 8 less nickels than dimes. If there is $8.30 in the purse, which equation could be used to determine the number of each type of coin?
So we know that John has 8 less nickels than dimes.
10¢= one dime
5¢= on nickel
8x5=40
Multiply 8 with 5 first because you know John hase 8 less nickels than dimes.
Subtract $8.30 with 40¢. Answer: $7.90. $7.90 divide 10 is 79 so then the left over is 0.
Final result: 79 dimes and 8 nickels.
Caleb solved this equation and recorded his work.
7.4x + 4.1(2x − 4) = −2.3(x − 6) − 21.6
1. 7.4x + 8.2x − 16.4 = −2.3x + 13.8 − 21.6
2. 15.6x − 16.4 = −2.3x + 35.4
3. 17.9x − 16.4 = 35.4
4. 17.9x = 51.8
5. x ≈ 2.89

Two electronics stores sell a video game that has a regular price of $49. A store discounts the video game by $15 and then adds 7.5% sales tax. Store B adds the tax first and then takes the discount. Are the selling prices the same? Justify your answer.
Answer:
The selling prices are same.
Step-by-step explanation:
According to the problem, given data are as follows:
Regular price = $49
Store A
Discounts first = $15
Price after discount = $49 - $15 = $34
Now adds 7.5% sales tax = $35 + ( $35 ×7.5%) = $35 + $2.625
So, final selling value = $37.625 or $38
Store B
Adds tax first = $49 + ($49 × 7.5%) = $49 + $3.675 = $52.675
Now deduct discount = $52.675 - $15
So, Final selling price = $37.675 or $38
As there is very minimal or no difference between both prices, so this considers to be same.

Answer:
slope: 0.10
Step-by-step explanation:
The independent variable is the number of texts, so that goes in the denominator of the slope ratio.
slope = (change in cost)/(change in texts)
= ($30 -25)/(100 -50)
= $5.00/50
slope = $0.10 per text

Alexia, Benito, and Carmen won a team art competition at their local park. As
part of their prize, they can paint the 5 km (5000 m) paved path through the
park any way they like.
They decided Alexia will paint the first 70 m, then Benito will paint the next
15 m, then Carmen will paint the next 35 m. They will keep repeating this
pattern until they reach the end of the 5 km path.
What percentage of the path will each person paint?
Answer:
Alexa: 58.8%
Benito: 12.5%
Carmen: 28.7%
Step-by-step explanation:
(70m + 15m + 35m)x=5000
x=41.67 times
41x120m=4920m, leaving 80 m which Alexa and Benito got an extra time.
Alexa painted 42 times
Benito painted 41.67 times
Carmen painted 41 times
Alexa: 42x70m=2940m, 2940/5000=58.8%
Benito: 41.67x15m=625m, 625/5000=12.5%
Carmen: 41x35m=1435m, 1435=/5000=28.7%

#27: Three cities form a right triangle on a map. Cities B and C are the furthest
apart. If cities A and B are 14 miles apart and cities A and Care 22 miles about,
how far about are cities B and C? Round the nearest tenth.
Answer: 26.1miles
Step-by-step explanation:
f three cities A, B and C form a right triangle on a map, and the Cities B and C are the furthest apart, then the distance between cities B and C will be the hypotenuse of the triangle.
If cities A and B are 14 miles apart, then |AB| = 14miles
Also if cities A and C are 22 miles apart, then |AC| = 22miles.
To get |BC| which is the distance between cities B and C, we will use the Pythagoras theorem.
|BC|² = |AB|² + |AC|²
|BC|² = 14²+22²
|BC|² = 196+484
|BC|² = 680
|BC| = √680
|BC| = 26.1miles
This means that cities B and C are 26.1miles apart

A cable company uses the formula S = 20,000 (1 + 0.08)y to estimate the number of subscribers, S, that use their service after y years. If there were 20,000 cable television subscribers when the cable company began, what is the meaning of the expression (1 + 0.08)Y?
Options :
A. Every year the number of subscribers is estimated to increase by 8 over the number
of subscribers the year before.
B. Every year the number of subscribers is estimated to increase by 8% of the original
20,000 subscribers
C. Every year the number of subscribers is estimated to increase by 8% over the
number of subscribers the year before.
D. Every year the number of subscribers is estimated to increase by 80% of the
original 20,000 subscribers.
Answer:
C. Every year the number of subscribers is estimated to increase by 8% over the
number of subscribers the year before.
Step-by-step explanation:
Given that:
The formula represents an exponential function :
S = 20,000 (1 + 0.08)^y
General form of an exponential equation :
y(x) = ab^x
Where a = initial value ; b = rate of change ; x = time
Comparing the formula given with the general equation:
a = 20000 = Number of subscribers when company began
b^x = (1 + 0.08)^y = percentage increase in the number of subscribers over y years

in wxy x=y, wx= 9x-11, xy= 4x-1, and wy= 7x-3, find x and the measure of each side
Answer:
WX = WY
9x - 11 = 7x - 3..........Then subtract 7x to the other side such that
2x - 11 = -3..........Then add 11 to both sides such that
2x = 8...........Then divide 2 such that
x = 4
Now we can find each side such that
WX = 9(4)-11 = 25
WY = 7(4)-3 = 25
XY = 4(4)+1 = 17
The value of x is 4 and the length of side WX is 25, WY is 25 and XY is 15 and this can be determined by using the given data and arithmetic operations.
Given :
Triangle WXY.Angle x [tex]\cong[/tex] Angle yWX = 9x -11XY = 4x-1WY = 7x-3Given that Angle x [tex]\cong[/tex] Angle y then according to properties of triangle WX = WY.
WX = WY
9x - 11 = 7x - 3
2x = 8
x = 4
Now, put the value of x in the given data in order to find the length of each side.
WX = 9(4) - 11 = 25
XY = 4(4) - 1 = 15
WY = 7(4) - 3 = 25

Given: y = 3x - 4. What is the x-intercept? (0, -4) ( 4/3 , 0) (0, 4/3 )
This equation is in slope-intercept form of y = mx + b form.
The m represented by the coefficient of the x term
represents the slope and b represents the y-intercept.
So our y-intercept is -4 and we can write this as the ordered pair (0, -4).
