While on vacation, Rosa stopped at a souvenir shop to buy
keychains and refrigerator magnets for family members and
friends. Keychains cost $2 each, and refrigerator magnets cost $1
each. Let x represent the number of keychains that Rosa bought,
and let y represent the number of refrigerator magnets.
Rosa bought 12 items and paid $18 more for the keychains than
for the refrigerator magnets.
9514 1404 393
Answer:
10 keychains2 magnetsStep-by-step explanation:
We assume you want to know how many of each item Rosa bought.
The problem information lets us write two equations:
x + y = 12
2x - y = 18
Adding the two equations, we get ...
3x = 30
x = 10 . . . . . divide by 3
y = 12 -x = 2 . . . find y
Rosa bought 10 keychains and 2 magnets.

Step-by-step explanation:
find the value of x in the following parallelogram: 2x-30, x+40
Answer:
x = 70
Step-by-step explanation:
Properties of a parallelogram.
1). Pair of opposite sides of a parallelogram are equal in measure and parallel to each other.
2). Opposite angles of a parallelogram are equal in measure.
3).Adjacent angles of a parallelogram are supplementary.
By the second property,
(2x - 30) = (x + 40)
2x - x = 30 + 40
x = 70

find the value of sin(a/2) if cosa= 12/13
Answer: sin[tex]\frac{a}{2}[/tex] = ± [tex]\frac{1}{\sqrt{26} }[/tex]
Step-by-step explanation:
We very well know that,
cos2A=1−2sin²A
⟹ sinA = ±[tex]\sqrt{(1-} \frac{cos2A}{2} )[/tex]
As required, set A = [tex]\frac{a}{2}[/tex] & cos a= [tex]\frac{12}{13}[/tex] ,thus we get
sin [tex]\frac{a}{2}[/tex] =± [tex]\sqrt{\frac{1-cos a}{2} }[/tex]
∴ sin[tex]\frac{a}{2}[/tex] =±[tex]\sqrt{\frac{1-\frac{12}{13} }{2} }[/tex] = ± [tex]\frac{1}{\sqrt{26} }[/tex]
since ,360° < [tex]\frac{a}{2}[/tex] <450°
,180° < [tex]\frac{a}{2}[/tex] <225°
Now, we are to select the value with the correct sign. It's is obvious from the above constraints that the angle a/2 lies in the III-quadrant where 'sine' has negative value, thus the required value is negative.
hope it helped!
In the diagram, AITP - ANGO. Find the values of
x and y.
y =
X=
Answer:
x = 25, y = 9
Step-by-step explanation:
Since the triangles are congruent then corresponding angles and sides are congruent, thus
∠ O = ∠ P , substitute values
6y - 14 = 40 ( add 14 to both sides )
6y = 54 ( divide both sides by 6 )
y = 9
and
NG = IT , that is
x - 2y = 7 ( substitute y = 9 into the equation )
x - 2(9) = 7
x - 18 = 7 ( add 18 to both sides )
x = 25
f(x) = 6x ^ 6 + 29x ^ 3 + 35x ^ 4 + 43x ^ 3 + 17x ^ 2 - 16x - 12

The marks obtained by Rama in seven subjects are 60, 53, 90, 65, 62,85 and 82. Find the average marks
Answer:
[tex]Average = 71[/tex]
Step-by-step explanation:
Given
Subjects = 7
Marks: 60, 53, 90, 65, 62,85, 82
Required
Determine the average mark
We start by adding the marks together.
[tex]Sum = 60 + 53 + 90 + 65 + 62 + 85 + 82[/tex]
[tex]Sum = 497[/tex]
Then divide the sum by number of subjects
[tex]Average = \frac{Sum}{Subjects}[/tex]
[tex]Average = \frac{497}{7}[/tex]
[tex]Average = 71[/tex]
Hence, the average mark is 71
The length of a rectangle is 5 feet and the width is 8 feet.what is the area of the rectangle
Answer:
40 ft squared
Step-by-step explanation:
To calculate area of a rectangle, you use the formula length times width, or base times height.
5 x 8 = 40 feet squared
Write the equation of the line that passes through the points (-6,6) and (-1, -9).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
y-6=-3(x+6)
Step-by-step explanation:
Find the slope first, using the slope formula.
y2-y1/x2-x1
-9-6/-1--6 = -15/5
Slope is -3
Put it into point-slope form using one of the coordinates.
y-y1=m(x-x1)
y-6=-3(x+6)

Evaluate g(x) = 9x ^ 3 - x ^ 2 + 2 for g(2)
Answer:
g(x)=9x^3-x^2+2 for g(2)
Step-by-step explanation:
g(2)=9.2^3-2^2+2
=18^3-2^2+2
=18^1^4
=18^4
=104,976

Dr.Pepper paid $1160 for a new sound system. She also paid a 7.5 % sales tax. What was the total cost including the tax?
Answer:
She paid 1247$ with tax

7.5% of 1160$ is 87$ you then add 87 to 1160$ to get 1247$
answer: its $1247
explanation: I had it wrong the first time cause I read it as 1660 instead of 1160 but. you do 1160×.075 yo get your sales tax which is 87 dollars. you then add that to your total.
