Nancy started the year with $425 in the bank and is saving $25 each week. Sam started the year with $705 but is spending S15 a week. Write a system of equations that model the following situation.
Define cach variables with a "Let" statement, write two equations, and solve completely.
Answer:
Step-by-step explanation:
Let x equal number of weeks and y equal money in the bank.
Nancy, y=425+25x
Sam, y=705-15x
The system of equations:
Nancy: [tex]y=\$425+\$25x[/tex]
Sam : [tex]y=\$705-\$15x[/tex]
Given:
Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
To find:
The system of equations describing the given models.
Solution
1) Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Let the number of weeks Nancy saving her money be 'x'.
Let the total amount of money in Nancy's bank after x weeks be 'y'.
[tex]y=\$425+\$25\times x\\y=\$425+\$25x[/tex]
The equation for Nancy:
[tex]y=\$425+\$25x[/tex]
2)
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
Let the number of weeks Sam spending his money be 'x'
Let the total amount of money left in Sam's bank after x weeks ='y'
[tex]y=\$705-\$15\times x\\y=\$705-\$15x[/tex]
The equation for Sam:
[tex]y=\$705-\$15x[/tex]

Find the 29th term in the arithmetic sequence: -13, -6, 1, 8........
Answer:
183
Step-by-step explanation:
a₁ = -13
common difference = a₂ - a₁
= (-6) - (-13)
= -6 + 13
d = 7
nth term = a₁ + (n - 1)d
29th term = -13 + 28 * 7
= -13 + 196

y= 2/3x what is the slope
Answer:
the slope is −3 .
Answer:
2/3 (fact checking...)
Step-by-step explanation:
this is a problem constructed in Slope-Intercept form, the slope is the angle that the line plotted is at.
The intercept, aka the y-intercept is where the line crosses on the y axis, in this case since y is just y and not changed, the line crosses at 0 on the y coordinate.
The slope is 2/3 because when plotted, the line will cross the point on graph at the location (x,y) 2,3 as its nearest whole set of numbered coordinates to 0,0 along said line
i really need help with this 6th grade work due today
5
Step-by-step explanation:
Length (L) = u
Breadth (b) = 6 mi
Perimeter (P) = 22 miles
Now we know
P = 2 (L+ b)
22 = 2 ( u + 6)
11 = u + 6
11 - 6 = u
u = 5
Answer:
u = 5
Step-by-step explanation:
The perimeter of a rectangle is all the sides added up.
The oppisite sides are parralel.
So the side across from 6 is all 6
6 + 6 = 12
The perimeter is 22 so you do
22 - 12 = 10
So 'u' equals 5 because you have to divide the number 10 by 2.
Dario is finding the percent of change from the original price of $75 to new price of $125.
Answer:

Write an
explicit formula for
an,
then
th
term of the sequence 100, 20, 4, ....
Answer:
Step-by-step explanation:
a1 = 100
r = 1/5
an = 100 (1/5)^(n - 1)
Try it. We have the answer for a_3
a_3 = 100 * (1/5)^(3 - 1)
a_3 = 100 * (1/5)^2
a_3 = 100 * 1/25
a_3 = 4 which is just what the series says should be the answer.
Given f(x) = -x + 2, find f(-5).
Answer:
7
Step-by-step explanation:
We have the expression -x + 2 and are asked to solve if x = -5.
Since we know the value of x, we need to replace x with the amount it is.
-x + 2 if x = -5.
-(-5) + 2
Negative cancels a negative.
5 + 2

The scale of a room in a blueprint is 5 in.: 9 ft. A wall in the same blueprint is 30 in. Complete the table.
Blueprint length (in.) 5

25
30
Actual length (ft)

How long is the actual wall?
The actual wall is
feet long
A window in the room has an actual width of 4.5 feet. Find the width of the window in the blueprint.
The width of the window in the blueprint is
in.
Answer:
54 feets
2.5 inches
Step-by-step explanation:
Given that:
Scale model:
5 in : 9ft
If 5 in = 9 ft
Hence, 1 in on the blue print equals
5 in = 9 ft
1 in = x
Cross multiply
5x = 9
x = 9/5 feets
Hence, 1 inches on the blueprint equals 9/5 feets actual
Blueprint length (in.) ___ Actual length (ft)
5 _________ 9
10 ________ 18
15 ________ 27
20 _______ 36
25 _______ 45
30 _______ 54
Hence ;
5 * 9/5 = 9 feets
10 * 9/5 = 18 feets
15 * 9/5 = 27 feets
20 * 9/5 = 36 feets
25 * 9/5 = 45 feets
30 * 9/5 = 54 feets
Window with actual width of 4.5 feets
Width of window in blue print :
Actual width ÷ 9/5
Actual width = 4.5 = 4 1/2 = 9/2
9/2 * 5 /9
= 5 /2
= 2 1/2 inches = 2.5 inches
What is the area of this triangle?
Answer:
The area of the triangle is 24 inches.
Step-by-step explanation:
First you multiply 8 by 6.
8 * 6 = 48
Next you divide by 2 because a triangle is half of a square.
48 ÷ 2 = 24
So, the answer is 24.
Hope this helps! :)
The area of triangle with base 6 inches and height 8 inches is 24in² .
Given, Right angled triangle .
Area of triangle = [tex]\frac{1}{2} \times b \times h[/tex]
Here,
b = base of triangle
h = height of triangle
Substitute the values,
Area of triangle = [tex]\frac{1}{2} \times b \times h[/tex]
[tex]= \frac{1}{2} \times 6 \times 8\\ = 3 \times 8\\= 24in^2[/tex]
