Answer:
Step-by-step explanation:
Let's solve your system by substitution.
32=4(n−5);−s+11=17
Rewrite equations:
32=4n−20;−s+11=17
Step: Solve 32=4n−20 for n:
32=4n−20
32+−4n=4n−20+−4n(Add -4n to both sides)
−4n+32=−20
−4n+32+−32=−20+−32(Add -32 to both sides)
−4n=−52
−4n/ −4 =/ −52/ −4
(Divide both sides by -4)
n=13
Step: Substitute 13 for n in −s+11=17:
−s+11=17
−s+11=17
−s+11+−11=17+−11(Add -11 to both sides)
−s=6
−s/ −1 = 6/ −1
(Divide both sides by -1)
s=−6
Answer:
n=13 and s=−6

8. Paris used a semicircle, a rectangle, and a right triangle to form the figure shown.
Which is the best estimate of the area of the figure in square centimeters?
F 100 cm2
G 88 cm2
H 50 cm2
J 74 cm2
= option J
area of figure = 1/2 × 6× 4 + 8×6 + 3.14× 9/2
= 12+ 48 + 3.14× 4.5
= 60+ 14.13
= 74.13 cm²
option J
plz mark my answer as brainlist plzzzz.

An infinite number of ratios are equivalent to 3:8. How
can that be possible, when the multiplication table only
goes to 9?
Answer:
See below, please!
Step-by-step explanation:
There are infinite number of ratios equivalent to 3:8 because both numbers can be multiplied by a common number or divided by a common number.
For example, 9:24 would still be equivalent to 3:8 because the common number in our case is 3. See what I mean?

Plot two points that are 777 units from Point \blueD{D}Dstart color #11accd, D, end color #11accd and also share the same xxx-coordinate as Point \blueD{D}Dstart color #11accd, D, end color #11accd.
Right format of question:
Plot two points that are 7 units from Point D and also share the same x-coordinate as Point D.
Answer:
[tex]D' = (-4,-6)[/tex] and [tex]D' = (-4,8)[/tex]
Step-by-step explanation:
Given
[tex]D(x,y) = (-4,1)[/tex]
Required
Determine a point 7 points from D and in the same x coordinate
Represent this point with D'.
From the requirement of the question, D' has two possible values and these values are:
[tex]D' = D(x,y-7)[/tex] ----> 7 units down and
[tex]D' = D(x,y+7)[/tex] ----> 7 units up
Substitute values for x and y in [tex]D' = D(x,y-7)[/tex] and [tex]D' = D(x,y+7)[/tex]
So, we have:
[tex]D' = D(x,y-7)[/tex]
[tex]D' = (-4,1 - 7)[/tex]
[tex]D' = (-4,-6)[/tex]
[tex]D' = D(x,y+7)[/tex]
[tex]D' = (-4,1+7)[/tex]
[tex]D' = (-4,8)[/tex]

Answer:
They are not
Step-by-step explanation:
4/5 cannot be simplified, plus 1/2 indicates half of a fraction but 4/5 is not half if a fraction, therefore they are not equivalent.

Answer:
8units²
Step-by-step explanation:
Area of the trapezoid = 1/2(a+b)h
a and b are the opposite sides
h is the height
Take a square as 1 unit
a = 1 unit
b = 3 units
height h = 4 units
Substitute
A = 1/2(1+3)*4
A = 1/2 * 4 * 4
A = 16/2
A = 8units²
Hence the area of the trapezoid is 8units²
plssssss someone help pls pls pls i dont get this look
Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 4(m∠Y) − 160°. Find m∠Y
Answer:
I think the answer is 50.
Step-by-step explanation:
Y + S = 90
S = 4 (Y) - 160
160 = 4 (Y)
Y = 40
90 - 40 = 50

3x + 1/3y=12
2y=18x+72
Show all work
A no solution
B one solution
C infinity solutions
Answer:
B one solution
Step-by-step explanation:
3x + 1/3y=12
2y=18x+72; y = 18x/2 +72/2; y =9x+36
3x + 1/3y=12
multiply all through by 3
9x + y = 36
9x + 9x+36 = 36
18x =36-36= 0
x= 0/18 = 0
y =9x+36
y = 9(0) +36 = 0+36= 36

WHAT ARE THE PRINCIPALS PLEASE HELP ME!
You have 2 different savings accounts. For Account A, the simple interest earned after
6 months is $4.63. For Account B, the simple interest earned after 21 months is $16.80. If the interest rate is 3.7% for Account A and 2.4% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal or initial amount of money invested.
R represents interest rate
T represents time
Considering the investment on account A,
I = $6.94
R = 3.7%
T = 9 months = 9/12 = 0.75 years
6.94 = (P × 3.7 × 0.75)/100 = 0.02775P
P = 6.94/0.02775 = $250
Considering the investment on account B,
I = $13.80
R = 2.3%
T = 18 months = 18/12 = 1.5 years
13.8 = (P × 2.3 × 1.5)/100 = 0.0345P
P = 13.8/0.0345 = $400
To determine the account that earned more interest in the first month,
250/9 = $27.8
400/18 = $22.2
Account A earned you the most interest the first month because $27.8 is higher than $22.2

Write an equation of the line that passes through the points (−6,20) and (0, 8).
Answer:
y = -2x + 8
Step-by-step explanation:
(−6, 20) and (0, 8)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(8 - 20) / (0 - (-6))
Simplify the parentheses.
= (-12) / (6)
Simplify the fraction.
-12/6
= -2
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = -2x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (0, 8). Plug in the x and y values into the x and y of the standard equation.
8 = -2(0) + b
To find b, multiply the slope and the input of x(0)
8 = 0 + b
b = 8
Plug this into your standard equation.
y = -2x + 8
This is your equation.
Check this by plugging in the other point you have not checked yet (-6, 20).
y = -2x + 8
20 = -2(-6) + 8
20 = 12 + 8
20 = 20
Your equation is correct.
Hope this helps!
