Answer:
price for one shirt
=
$
7.50
price for one pair of pants
=
$
18.50
Explanation:
Start by letting variables
x
and
y
represent the pieces of clothing from the problem.
Let
x
be the price of one shirt.
Let
y
be the price of one pair of pants.
Equation
1
:
4
x
+
3
y
=
85.50
Equation
2
:
3
x
+
5
y
=
115.00
You can solve for each variable by using elimination or substitution. However, in this case, we will use use elimination. First, we will solve for
y
, the price of each pair of pants.
To isolate for
y
, we must eliminate
x
. We can do this by making the two equations have the same
x
values. First, we find the LCM of
4
and
3
, which is
12
. Next, multiply equation
1
by
3
and equation
2
by
4
so that
4
x
and
3
x
becomes
12
x
in both equations.
Equation
1
:
4
x
+
3
y
=
85.50
3
(
4
x
+
3
y
)
=
3
(
85.50
)
12
x
+
9
y
=
256.50
Equation
2
:
3
x
+
5
y
=
115.00
4
(
3
x
+
5
y
)
=
4
(
115.00
)
12
x
+
20
y
=
460.00
Now that we have two equations with
12
x
, we can subtract equation
2
from equation
1
to solve for
y
.
12
x
+
9
y
=
256.50
12
x
+
20
y
=
460.00
−
11
y
=
−
203.50
y
=
18.50
⇒
price for one pair of pants
Now that we know that a pair of pants is
$
18.50
, we can substitute this value into either equation
1
or
2
to find price for one shirt. In this case, we will choose equation
1
.
4
x
+
3
y
=
85.50
4
x
+
3
(
18.50
)
=
85.50
4
x
+
55.5
=
85.50
4
x
=
28
x
=
7.50
⇒
price for one shirt
∴
, the price for one shirt is
$
7.50
and the price for one pair of pants is
$
18.50
.

The interior angles of a triangle have measures 90°, 48°, and xº.
What is the value of x?
Answer:
42°
Step-by-step explanation:
The interior angles of a triangle always add to 180 degrees.
90+48+x=180
x=180-90-48
=42
x is 42°
To solve for n, I should do what to both sides of the equation? n - 8 = 13

B. Subtract 8 from both sides of the equation.
C. Subtract 13 from both sides of the equation.
D. Add 13 to both sides of the equation.

A rake was marked up 25% from an original cost of $8.80. Last Friday, Dean bought the rake and paid an additional 3% in sales tax. What was his total cost?
Answer:
$11.33
Step-by-step explanation:
First I did 8.80 x 0.25 and I got 11. Than I did 11.00 x 0.03 and I got $11.33. The total cost was $11.33
The total cost of the rake is $11.33.
What is the sales tax?Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.
Given that, a rake was marked up 25% from an original cost of $8.80.
25% of the original cost of $8.80 is
0.25×8.80 =$2.2
So the marked up price was 8.80+2.20
= $11
He then paid an additional 3% in sales tax, that is
11 + 0.03×11 = $11.33
Therefore, the total cost of the rake is $11.33.

The angle of elevation of an electricity pole from a point 8 metres from its base is 52.7 degrees. What is the height of the pole?
Answer:
10.5m
Step-by-step explanation:
We solve the above question, using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
θ = 52.7 °
Adjacent = 8 m
Opposite = x
Hence,
tan 52.7= x/8m
Cross Multiply
x = tan 52.7 × 8m
x = 10.501501092m
Approximately = 10.5 m
Therefore, the height of the pole = 10.5m

Answer:
That would be -2n - 1.
Answer:
-2n - 1
Step-by-step explanation:
You have to combine like term which would be 4n,n,and 7n.
Since n doesn't have a variable just add a one in front. So now the equation would be
1n+4n-7n That equation equals -2n
Now just add the remaining number
So that makes the answer -2n -1

Answer is in attachment. I am really sorry if I'm wrong.
Step-by-step explanation:
Finding the height:Greatest common factor (GCF) is the highest number that is a factor of 2 numbers. Not sure if that makes sense.
For example, GCF of 8 and 4 is 4, because 4 is the highest factor that fits into both numbers. 4x2=8 and 4x1=4.
In this case, the height is 7, because that's the GCF of 21 and 70. There's no bigger common factor than that. 7x3=21 and 7x10=70
Finding the length and area:Now that we know the "height", even though there's no such thing as height when calculating the area, we know the length.
The area of something is length x width. Your assignment calls it height for some reason so we'll use height x length.
Area of the 2 shapes is already given, which is 21n for the first shape. Length of the first shape is 3n because 3nx7=21n. Recall that 7 is what we found earlier.
As we can see, the "height" of the 2nd shape is the same as the first, therefore it should also be 7.
Since we are given the area of the 2nd shape, we now know its length. Length of 2nd shape is 10, because 7x10=70.
Find the volume, V, of a right circular cylinder in terms of π, if its height is 5 yards, and the radius of its base is 2 yards.

what is this simplify?
Answer:
D. 2^7
Step-by-step explanation:
Answer:
2^7
Step-by-step explanation:
When we multiply the same bases with exponents like 2^3*2^4 we can add the exponents and keep the base the same
2^7 would be the answer or you can simplify further to get 128
but they said simplify so 2^7 is the answer
If they said evaluate then our answer is 128

Answer:
Equation B and Equation C
Step-by-step explanation:
We can pinpoint a solution of an equation on a graph by looking at where the two lines intersect. The points (2,12) quite literally mean when x is 2, y is 12. If two equations intersect at that very point, that is their solution.

determine the intercepts of the line
Answer:
(0, -5/2), (-2, 0)
Step-by-step explanation:
To find the y-intercept, set x = to 0 and find y: -4y = 10. Thus, y = -5/2. The y-intercept is (0, -5/2).
To find the x-intercept, set y = to 0 and fid x: -5x = 10. Therefore the x-intercept is -2: (-2, 0)

If h(x) = 5x - 3 and j(x) = -2x, solve hlj(2)] and select the correct answer below. (1 point)
17
23
-17
-23
Answer:
-23
Step-by-step explanation:
We are given the functions;
h(x) = 5x - 3 and j(x) = -2x
Now, we want to find h[j(2)]
j(2) = -2(2)
j(2) = -4
Thus;
h(-4) = 5(-4) - 3
h(-4) = -20 - 3
h(-4) = - 23
