Aria has a points card for a movie theater. She receives 85 rewards points just for signing up. She earns 12.5 points for each visit to the movie theater. She needs 185 points for a free movie ticket. How many visits must Aria make to earn a free movie ticket?
Answers
Answer:
8 visits
Step-by-step explanation:
Create an equation, where x is the number of visits to the theater.
Since she gets 12.5 points for each visit, the number of points from visits will be represented by 12.5x.
85 will be added to this, since she gets 85 points for signing up. Then, this will be set equal to 185, since she needs 185 points for the free ticket.
12.5x + 85 = 185
Solve for x:
12.5x = 100
x = 8
So, Aria needs to make 8 visits to earn a free movie ticket
Aria must make 8 visits to earn a free movie ticket when She needs 185 points for a free movie ticket.
By given she has 85 rewards points just for signing up.
She earns 12.5 points for each visit to the movie theater.
She needs 185 points for a free movie ticket.
We must find how many visits does aria has to make to earn a free movie ticket
What is equation?If two expressions with equal sign is called as equation.
Let x is the number of visits to the theater.
Since she gets 12.5 points for each visit, the number of points from visits will be represented by 12.5x.
85 will be added to this, since she gets 85 points for signing up. Then, this will be set equal to 185, since she needs 185 points for the free ticket.
12.5x + 85 = 185
12.5x = 100
x = 8
So, Aria needs to make 8 visits to earn a free movie ticket

The area of a triangle is 30 square inches. What is the length of the base if the height is 6 centimeters?
Answers
Answer:
x = 10 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = x, h = 6 and A = 30 , then
[tex]\frac{1}{2}[/tex] × 6 × x = 30
3x = 30 ( divide both sides by 3 )
x = 10
The length of the base is 25.4 cm.
A triangle is a 3-sided polygon. The sum of angles in a triangle is 180 degrees.
Types of triangle
Equilateral triangle Scalene triangle Isosceles triangleRight triangleLength of the base of a triangle = (2 x area) / height
1 inch = 2.54 cm
30 x 2.54 = 76.20cm
(2 x 76.20) / 6 = 25.4 cm

Dan and Lisa each improved their yards by planting daylilies and ivies. They bought their supplies from the same store. Dan spent $78 on 6 daylilies and 8 pots of ivies. Lisa spent $123 on 9 daylilies and 13 pots of ivies. What is the cost of one daylily? What is the cost of one pot of ivies?
Answers
Answer:
Cost of daylillies = $5
Cost of pot = $6
Step-by-step explanation:
Let
Cost of daylillies = x
Cost of pot = y
6x + 8y = 78 (1)
9x + 13y = 123 (2)
Multiply (1) by 9 and (2) by 6 to eliminate x
54x + 72y = 702 (3)
54x + 78y = 738 (4)
Subtract (3) from (4)
78y - 72y = 738 - 702
6y = 36
y = 36/6
y = 6
Substitute y = 6 into (1)
6x + 8y = 78 (1)
6x + 8(6) = 78
6x + 48 = 78
6x = 78 - 48
6x = 30
x = 30/6
x = 5
Cost of daylillies = $5
Cost of pot = $6

HELP PLEASE!! Alita is 2 times as old as Jiro. Jiro is 4 years younger than Erik. Erik is 1/3 as old as dawn. The sum of all their ages is 72 What equation could you write to represent this situtation????
Answers
Step-by-step explanation:
72= (e= 1/3d ) + (j= e-4) + (a= 2j)
or
1/3d - 4 × 2 =72
let d = dawn
let e = erik
let j = jiro
let a = alita
remember that a number next to a variable means multiplication.
The equation could write to represent this situation is
72= (e= 1/3d ) + (j= e-4) + (a= 2j)
What is equation?An equation can be defined as a statement that supports the equality of two expressions joined by the equal sign "=". For example, 2x – 5 = 13. These are the expressions 2x – 5 and 13.The sign connecting these two expressions is "=".
In algebra, an equation is a condition of a variable. It will be filled only with the value specified by the variable. This means that the equation 2x – 5 = 13 is satisfied only when x = 9.
Equations are different, for example:
Linear equations Quadratic equations Cubic equations Quartic equations Differential equations Parametric equationsLet us suppose ,
age of Erik is e
dawn is d
Jiro is j
Alita is a
The equation could write to represent this situation is
72= (e= 1/3d ) + (j= e-4) + (a= 2j)

Answer:
0.19/lb
Step-by-step explanation:
When computing cost per quantity, the cost is divided by the quantity.
2.99/(16 lb) = 0.186875/lb ≈ 0.19/lb
Answer:
heyy it's me again lol but The unit rate is $0.19/lb.
Step-by-step explanation:
Divide the total by the number of pounds to get the price per pound, or the unit rate.
$2.99 ÷ 16 lb = 0.186875
Since 0.186875 isn't an accurate US dollar amount, round to nearest hundredth, 0.19.
so you answer is $0.19/Ib

[tex]\frac{5z+1}{3}[/tex] = 7 ( multiply both sides by 3 to clear the fraction )
5z + 1 = 21 ( subtract 1 from both sides )
5z = 20 ( divide both sides by 5 )
z = 4
(b)
[tex]\frac{5x}{3}[/tex] + 3 = x + 7 ( multiply through by 3 to clear the fraction )
5x + 9 = 3x + 21 ( subtract 3x from both sides )
2x + 9 = 21 ( subtract 9 from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
