Answer:
[tex]2 \: jeans = 2{(4x - 5)} \\ = 8x - 10 \\ balance = (10x + 7) - (8x - 10) \\ = (10 - 8)x + (7 + 10) \\ 2x + 17 \: dollars[/tex]

Tickets to the movies cost $9.50 for adults and $6.50 for kids. A large group bought 12 tickets and spent a total of $87. How many kid's tickets did the group purchase?
Please include an equation.
Answer:
12 ticketsStep-by-step explanation:
please brainleist please tysm☺️☺️☺️☺️☺️
Answer:
9 kid's ticketsStep-by-step explanation:
Given
Kid's tickets = k, one ticket costs $6.5, total cost 6.5kAdult tickets = a, one ticket costs $9.5, total cost 9.5aEquations:
a + k = 129.5a + 6.5k = 87Substitute a into second equation a = 12 - k and solve for k:
9.5(12 - k) + 6.5k = 87114 - 9.5k + 6.5k = 873k = 114 - 873k = 27k = 9A house has a square room with an area of 125 ft2.

3. Determine whether or not AB is tangent to circle O. Show your work.
Answer:
not tangent
Step-by-step explanation:
two reasons, first
Triangle AOB is not a right triangle
line AB intersects the circle O at two points.
The line AB touching the circle at point B in the considered diagram is not tangent to the circle O.
What is Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).
How are radius and tangent to a circle related?There is a theorem in mathematics that:
If there is a circle O with tangent line L intersecting the circle at point A, then the radius OA is perpendicular to the line L.
So, if AB is a tangent, then ∠ABO = 90° and therefore satisfies Pythagoras theorem.
Assuming AB is tangent, then ABO is right angled we should get:
[tex]H^2 = P^2 + B^2\\30^2 = 16^2 + 12^2\\900 = 256 + 144\\900= 500[/tex]
This statement is false, and therefore, so as our assumption is false that AB is tangent to circle O. Thus, AB is not tangent to circle O.
(so it might be that even if AB looks like touching at one point the circle O, but AB might be intersecting the circle at two points, or not touching it at all)
Thus, the line AB touching the circle at point B in the considered diagram is not tangent to the circle O.

In AGHI, the measure of ZI=90°, the measure of ZG=5°, and IG = 57 feet. Find the
length of GH to the nearest tenth of a foot.
9514 1404 393
Answer:
57.2 ft
Step-by-step explanation:
The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(G) = IG/GH
GH = IG/cos(G) = (57 ft)/cos(5°)
GH ≈ 57.2 ft

Let

t
tt months.
Complete the equation for the relationship between the weight and number of months.
W
=
W=W, equals
Answer:
W = 6t + 90
Step-by-step explanation:
Given :
Starting weight = intercept = 90 kg
Weight gained after 8 months = 138 kg
Using the slope intercept relation ;
We can obtain the rate of change, slope ;
y = mt + c
m = slope ; t = time after t months ; c = intercept
y = weight gained after 8 months
138 = 8m + 90
138 - 90 = 8m
48 = 8m
m = 48 / 8
m = 6
Hence, slope intercept equation equals :
W = 6t + 90

Humphrey needs to mail a package. He weighs it at home as 20.2 ounces. When he gets to the post office, the clerk weighs it at 18.6 ounces. What is the percent error in the weight of the package, assuming that his home weight is the correct weight?
Answer:
7.92%
Step-by-step explanation:
Given the following
Weight of package at home = 20.2 ounces.
Weight of the package at the office = 18.6ounces
Decrement = 20.2 - 18.6
percentage error = decrement/wt at home * 100
percentage error = 1.6/20.2* 100
percentage error = 160/20.2
percentage error = 7.92
HEnce the percent error in the weight of the package is 7.92%

This is an AP with:
The first term a₁ = 12Common difference d = 3Number of terms n = 40Number of the seats:
Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seatsFormula of nth term:
aₙ = a₁ + (n - 1)daₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9aₙ = 3n + 9Using the markings below, determine which of the following is the measure of angle 2

Pls help I will give u five stars
Answer:
x=8
Step-by-step explanation:
First set the equations equal to each other
8x+36=5x+60
Subtract 36 from both sides
8x+36-36=5x+60-36
Simplify
8x=5x+24
Subtract 5x from both sides
8x-5x=5x+24-5x
Simplify
3x=24
Divide both sides by 3
3x/3=24/3
Simplify
x=8
