Answer:
x=5.75 ; price of a single popcorn
y=2.25 ; price of a drink
system of equations
2*x+3*y= 18.25
4*x+2*y=27.50
Step-by-step explanation:
x= price of popcorn
y= price of drink
2*x+3*y= 18.25 ; this is information for Mohamed
4*x+2*y=27.50 ; this is informtion for miguel
solve an equation for y
2y=27.50-4x
y=13.75-2x
substitue into other equation
2*x+3(13.75-2x)=18.25
2*x+41.25-6x=18.25
-4x+41.25=18.25
-4x=-23
x=5.75 ; price of a single popcorn
swap x=5.75 into the other equation
4*5.75+2*y=27.50
2y=4.5
y=2.25 ; price of a drink
put back in to check work
2*5.75+3*2.25
11.5+6.75=18.25

two hot airballoons are travelingalong the samepath away from town beginningfrom difrant locationsat the same time henery's balloon begins 15 miles from the town and is 31 miles from the town after 2 hours. the distanceof tasha'sballoon from the town is represented by the function y=5x+25
witch ball on was farther from the town at the beginning and which traveled more quickly?
A. tasha's balloon was further from the town at the beginning and it traveled more quickly.
B. Henry's balloon was further from the town at the beginning and it traveled more quickly.
C. Henry's balloon was further from the town at the beginning but tasha's balloon traveled more quickly
D. tasha's balloon was further from the town at the beginning but henery's balloon traveled more quickly
Answer: I think it is B
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
tasha's ballon speed=5 mph
henrey's balloon speed=(31-15)/2=16/2=8 mph
tasha's initial distance was y=5×0+25 =25 miles
Henrey's balloon initial distance=15 miles

The interior angle of a regular polygon is 165º.
How many sides does the polygon have?
Answer:
24 sides
Step-by-step explanation:
An exterior angle of a regular polygon is 360 divided by the number of sides. The exterior angle is equal to the interior angle subtracted from 180. We can say an exterior angle of this polygon is 180 - 165 or 15. From the first property, we can write an equation:
360/n = 15
360 = 15n
n = 24
24 sides
Another way to do this, is the formula for an interior angle of a regular polygon is:
180(n - 2)/n
This is equal to the interior angle:
180(n-2)/n = 165
180n - 360 = 165n
15n - 360 = 0
15n = 360
n = 24
Paige ran four miles a day last week. This week, she ran five miles a day. How did adding a mile most likely affect her workout?
Answer:
A. It increased both her intensity and her workout time.
Step-by-step explanation:
A. It increased both her intensity and her workout time.
B. It decreased her intensity but increased her workout time.
C. It increased her intensity but decreased her workout time.
D. It decreased both her intensity and work out time
Last week = 4 miles per day
This week = 5 miles per day
Intensity refers to how hard one exercises.
Workout time refers to how long one exercises the body.
By adding a mile, she has increased how hard she exercises her body (intensity))
And also increased how long she exercises the body (workout time) because the time she spent on 5 miles per day is more than time spent on 4 miles per day
Find the domain of f/g.
A.
B.
C.
D.
Answer:
C. All real numbers except [tex]\frac{3}{4}[/tex].
Step-by-step explanation:
The domain of all polynomials is the set of all real numbers, whereas the domain of rational-polynomic functions are the set of all numbers expect for those values of [tex]x[/tex] so that denominator becomes zero. Hence, we need to solve for [tex]x[/tex] from following expression:
[tex]4\cdot x - 3 = 0[/tex]
[tex]4\cdot x = 3[/tex]
[tex]x = \frac{3}{4}[/tex]
The domain of the function is all real numbers except [tex]\frac{3}{4}[/tex]. (Right answer: C)
Complete these ordered pairs for this equation.
(0, ), (-1,), (1, ) y=2x+1
Helpp
Given:
The equation is:
[tex]y=2x+1[/tex]
To find:
The y-coordinates for the ordered pairs (0, _), (-1, _) and (1, _)for this equation.
Solution:
We have,
[tex]y=2x+1[/tex]
For [tex]x=0[/tex],
[tex]y=2(0)+1[/tex]
[tex]y=0+1[/tex]
[tex]y=1[/tex]
For [tex]x=-1[/tex],
[tex]y=2(-1)+1[/tex]
[tex]y=-2+1[/tex]
[tex]y=-1[/tex]
For [tex]x=1[/tex],
[tex]y=2(1)+1[/tex]
[tex]y=2+1[/tex]
[tex]y=3[/tex]
Therefore, the complete ordered pairs are (0,1), (-1, -1) and (1,3). Plot these points on a coordinates plane and connect them by a straight line as shown in the below figure.

Question on the image
Answer:
m =10
Step-by-step explanation:
Barry = m
S = m+5 since they are 5 years older
A = m-3 since they are 3 years younger
Add to get the total
m + (m+5) + (m-3) = 32
Combine like terms
3m +2 = 32
Subtract 2 from each side
3m+2-2 = 32-2
3m = 30
Divide by 3
3m/3 = 30/3
m =10

The theater sells two types of tickets: adult tickets for $15 and
child tickets for $11.
Last night, the theater sold a total of 147 tickets for a total of
$1889. How many adult tickets did the theater sell last night?
Answer:
68
Step-by-step explanation:
Let x=adult tickets and y=child tickets
1) 15x+11y=1889
2) x+y=147
multiply equation 1 by -1/11 on both sides to get:
-(15/11)x-y=-171.73
add new equation with equation 2 to get
-4/11x=-24.73
Isolate x to get:
x=67.99999
Round up to get 68 adult tickets

1. Why are all rectangles parallelograms, but all parallelograms are not rectangles?
2. What properties must a quadrilateral posses in order for the quadrilateral to be classified as a:
a) trapezoid
b) isosceles trapezoid?
Answer:
1: Because all lines on a rectangle never touch so it is a parallelogram. But all sides of a square don't touch either, so that's also a parallelogram. So not all parallelograms are rectangles since squares are also parallelograms
Step-by-step explanation:
Answer:
Step-by-step explanation:
1. All internal angles of a rectangle are 90° while the internal angles of a parallelogram may differ
2. A quadrilateral just means anything with 4 sides (quad meaning 4 and lateral meaning sides) and it is 2-dimensional with straight sides.
Therefore, the trapezoid and isosceles trapezoid are quadrilateral
a) A quadrilateral must have a pair of parallel sides to be classified as a trapezoid.
b) A quadrilateral must have the left and right side to be of equal length and the base angles equal to be classified as an isosceles trapezoid

Find the measure of angle 3
I WILL GIVE BRAINLIEST TO THE CORRECT ANSWER
Answer:
90
Step-by-step explanation:
4x+22=-6x+192 since 4x+22 is the same as angle 5 due to parallel lines, and then 5 = -6x+192 as it is straight across.
4x+22=-6x+192
10x+22=192
10x=170
x=17
plug back in to equation
4(17)+22= 90
Answer:
∠3 = 90°
Step-by-step explanation:
∠4 = ( 4x + 22 )° [ Vertically opposite angles ]
∠4 = ( -6x + 192)° [ Corresponding angles ]
Therefore ,
4x + 22 = - 6x + 192
4x + 6x = 192 - 22
10x = 170
x = 17
∠4 = 4x + 22 = (4 × 17 ) + 22 = 90°
∠4 = 90°
∠3 + ∠4 = 180°
∠3 + 90° = 180°
∠3 = 180° - 90°
∠3 = 90°

How can you tell if 2 functions are inverses of each other?
Answer:
If the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions. But, we need a way to check without the graphs, because we won't always know what the graphs look like! then f(x) and g(x) are inverse functions.
