both angles are the same ! so
20x + 60 = 30x + 20
10x = 40
x = 4
and then substitute x back in
20(4) + 60 = 140

Jayson has 97 tickets to give away. He gave 4 tickets to each student in his class and has one leftover.
How many students in his class?
Answers
Answer:
4 ; 24
Step-by-step explanation:
A.)
Fixed fee, x = $5
Hourly rate, y = $3
Total rent fee, t= $17
Number of rent hours :
$17 = $5 + $3y
17 - 5 = 3y
12 = 3y
y = 12/3
y = 4 hours
B.)
Total Number of tickets , t = 97
Tickets per student, r = 4
Tickets left = 1
Number of students in class:
(97 - 1) / 4
96 /4
= 24 students

The points after dilation is (27, 18).
What is Dilation?Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original.
Enlargements are dilations that result in a larger image. Reduction is the name for a dilatation that shrinks the image. The initial figure is stretched or contracted by a dilatation.
Given:
Scale Factor= 3
Points (9, 6).
If the coordinates is dilated by factor 3.
Then, (9, 6).
= (9(3), 6(3)).
= (27, 18)
Hence, the points after dilation is (27, 18).

Which system of inequalities is shown?
A y<x y>4 B y>x y
Answers
Given:
The graph of the system of inequalities.
To find:
The system of inequalities.
Solution:
In the given graph, we have two dotted boundary lines.
First boundary line is passes through (-1,1), (0,0) and (1,1), so it represents a proportional relationship and the equation of this boundary line is
[tex]y=x[/tex]
Second boundary line is a horizontal line passes through the point (0,4). So, the equation of this boundary line is
[tex]y=4[/tex]
Shaded portion lies below these boundary line and these boundary lines are dotted. So, the sign of inequity must be <.
The system of inequalities is
[tex]y<x[/tex]
[tex]y<4[/tex]
Therefore, the correct option is D.

Dan was thinking of a number. Dan divides by 5, then adds 3 to get an answer of 3. What was
the original number?
Answers
Answer:
The original number was: x = 0
Step-by-step explanation:
Let 'x' be the number
Given that:
Dan first divides it by 5
x/5
Then adds 3
x/5 + 3
To get an answer of 3
x/5 + 3 = 3
now solving the expression
[tex]\frac{x}{5}+3=3[/tex]
Subtract 3 from both sides
[tex]\frac{x}{5}+3-3=3-3[/tex]
Simplify
[tex]\frac{x}{5}=0[/tex]
Multiply both sides by 5
[tex]\frac{5x}{5}=0\cdot \:5[/tex]

Lucas bought square tiles to retile the
lobby of Town Travel Agency. Each
side of a tile is 11 inches long. If Lucas
uses the formula for the area of a
square, A = s2, how many square
inches will each tile cover?
00 ft.?
Answers
Answer:
121 in² ; 0.840 ft²
Step-by-step explanation:
Given that:
Side length of square tile, s = 11 inches
The Area of a square = a² ;
Where a = side length
Hence, we Can get the area of the square tile using the area of square formula :
Area of square tile = 11² = 121 in²
Area in feets :
1 ft² = 144 in²
x = 121 in²
144 x = 121
x = 121 / 144
x = 0.840 ft²

Your dinner costs $21.50 before tax. If you used a fifteen percent off coupon
and then you are charged seven percent sales tax, what is your balance with tax?
Answers
Answer:
$19.55
Step-by-step explanation:
Discount = 15% of 21.50
= 0.15 * 21.50
= 3.225
= $ 3.23
Balance need pay = 21.50 - 3.23 = $ 18.27
Tax = 7% of 18.27
= 0.07 * 18.27
= $1.28
Balance with tax = 18.27 + 1.28 = $ 19.55

(8,5); perpendicular to 2x - y = 7
Answers
Answer:
brainliest plzzz
Step-by-step explanation:
2x - y = 7 is in standard form, and if it were slope-intercept form that would help you. I got the y term by itself:
y = 2x - 7 slope-intercept form. You already know the slope of the perpendicular line is the *negative reciprocal* of the slope you have. So that's (-1/2). The perpendicular line is something like
y = -(1/2)x + b and if you substitute 8 for x and 5 for y you get 9 for b.
y = -(1/2)x + 9 is your perpendicular line. In slope-intercept form. To get back to standard form, start by getting rid of fractions. Multiply both sides by 2.
2y = -x + 18 then add x to both sides.
x + 2y = 18 done.
7696 divided by 52 with remainder
Answers
Answer:148 with no remainder
Step-by-step explanation:
The number 7696 is called the numerator or dividend, and the number 52 is called the denominator or divisor.
The quotient of 7696 and 52, the ratio of 7696 and 52, as well as the fraction of 7696 and 52 all mean (almost) the same:
7696 divided by 52, often written as 7696/52 is 148 with not decimals meaning that there is no remainder
Hope you have a wonderful day and may your dreams come true!
lfu29
When 7696 divided by 52 then quotient is 148 and remainder is 0.
When you divide 7696 by 52, the quotient is the whole number result of the division, and the remainder is the amount left over.
Let's perform the division:
148 (quotient)
______________
52 | 7696
7696
-----
000
The quotient is 148, and the remainder is 0.
So, 7696 divided by 52 is equal to 148 with a remainder of 0.

What is an algebraic expression?An algebraic expression is consists of variables, numbers with various mathematical operations.
The given expressions are (3y + 1) + (2y + 8) and (ny + 9)
Also, both the expressions are equivalent to each other.
To find the value of n, equate expressions (3y + 1) + (2y + 8) and (ny + 9),
3y + 1 + 2y + 8 = n y + 1
5y + 9 = n y + 1
5y + 9 - 1 = n y
5y + 8 = n y
n = (5y + 8) / y
n = 5 + 8/y
The required value of n is 5 + 8/y.
