Julie used her gift card for the local coffee shop to buy iced teas for herself and five friends. After she and one friend placed their orders, the balance on Julie’s gift card was $14.85. After all six members of the group got their iced teas, she had a balance of $3.97 on her gift card. Determine the cost for one glass of iced tea.
Answer:
One glass of iced tea cost $2.72
Step-by-step explanation:
Let,
x be the amount of gift card.
y be the amount of one glass of iced tea.
According to given statement;
Julie and her friend bought tea and remaining balance was $14.85
x - 2y = $14.85 Eqn 1
All the six members bought tea and remaining balance was $3.97
x - 6y = $3.97 Eqn 2
Subtracting Eqn 2 from Eqn 1
[tex](x-2y)-(x-6y)=14.85-3.97\\x-2y-x+6y=10.88\\4y=10.88[/tex]
Dividing both sides by 4
[tex]\frac{4y}{4}=\frac{10.88}{4}\\y=2.72[/tex]
Hence,
One glass of iced tea cost $2.72
A flower bed is 3 meters wide and 5 meters long. What is the area of the flower bed in square feet? Round intermediate calculations and your answer to the nearest hundredth.
1 meter = 3.28 feet
3 meters x 3.28 = 9.84 feet
5 meters x 3.28 = 16.4 feet.
Area = Length x width
Area = 9.84 x 16.4 = 161.38 square feet.
1 meter = 3.28 feet
3 meters x 3.28 = 9.84 feet
5 meters x 3.28 = 16.4 feet.
Area = Length x width
Area = 9.84 x 16.4 = 161.38 square feet.

The sum of the present age of a mother and her son is 35 and the difference is 25 years.find their present age.(By substitution or elimination method).
Answer:
Son = 5 years old
Mum = 30 years old
Step-by-step explanation:
Let the Mum be M and the Son be S;
[tex]M + S = 35[/tex] --- Sum
[tex]M - S = 25[/tex] -- Difference
Required
Find M and S (their ages)
Using elimination method; Add both equations to eliminate S
[tex]M + S = 35[/tex]
[tex]M - S = 25[/tex]
----------------
[tex]M + M + S - S = 35 + 25[/tex]
[tex]2M = 60[/tex]
Solve for M
[tex]M = \frac{1}{2} * 60[/tex]
[tex]M = 30[/tex]
Substitute 30 for M in [tex]M + S = 35[/tex]
[tex]30 + S= 35[/tex]
Solve for M
[tex]S = 35 - 30[/tex]
[tex]S = 5[/tex]
Hence:
Son = 5 years old
Mum = 30 years old

Answer:
1) x=35 2) y=98 3) x=49.5
Step-by-step explanation:
I can't take a picture right now, but I'll come back an edit. If you see this, reply or something so that I can easily find it again.
Before I edit and upload a picture of my work basically, you cross multiply then solve them you will 7 by 30 and 6 by x. Write that down 6x=210 (7 x 30) divide by 6 on both sides. you get x=35
multiply 3 and y, and 7 and 42. 3y=294. Divide 3 on both sides and you get y=98.
multiply x and 24, and 44 and 27. You get 24x=1188. divide 24 on both sides and you get x=49.5

A recipe calls for 3 cups of sugar and 9 cups of water. How many cups of water should be used with 2 cups of sugar?
Answer:
6 cups
Step-by-step explanation:
Could i have branliest and heart please
THanks and have a good day!
Answer:
6 cups of water
Step-by-step explanation:
If you divide the number of cups of water by the number of cups of sugar then you will find how many cups of water for 1 cup of sugar. So you would do 9/3 which gives you 3. This means that you will have 3 cups of water for 1 cup of sugar. So for two cups of sugar you would just add 3 more cups of water which you give you 6

The vertices of AJKL are J(-3, -2), K(1, 4), and L(4, 2). Which coordinate pairs are vertices of D5(^JKL)? Select all that apply.
Given:
The vertices of ΔJKL are J(-3, -2), K(1, 4), and L(4, 2).
To find:
The coordinate pairs of vertices of [tex]D_5(\Delta JKL)[/tex].
Solution:
We know that, [tex]D_5(\Delta JKL)[/tex] means triangle JKL dilated by scale factor 5 with origin as center of dilation.
If a figure is dilated by factor k and origin is the center of dilation, then
[tex](x,y)\to (kx,ky)[/tex]
From the given problem, the rule of dilation is
[tex](x,y)\to (5x,5y)[/tex]
Now,
[tex]J(-3,-2)\to J'(5(-3),5(-2))=J'(-15,-10)[/tex]
[tex]K(1,4)\to K'(5(1),5(4))=K'(5,20)[/tex]
[tex]L(4,2)\to L'(5(4),5(2))=L'(20,10)[/tex]
Therefore, the coordinate pairs of vertices of [tex]D_5(\Delta JKL)[/tex] are J'(-15,-10), K'(5,20) and L'(20,10).
Answer:
J’ = (-15, -10)
K’ = (5, 20)
L’ = (20, 0)

Hey I need help just leave answer thx
Answer:
x = 61
Step-by-step explanation:
The angle above the line n adjacent to 2x - 6 is (x + 3) alternate angle.
Adjacent angles are supplementary, thus
2x - 6 + x + 3 = 180, that is
3x - 3 = 180 ( add 3 to both sides )
3x = 183 ( divide both sides by 3 )
x = 61

A bus can hold 24 adults or 30 children. 25 children are already on the bus. What is the greatest number of adults that can still get on the bus.
Answer:
4 adults
Step-by-step explanation:
Given that:
Capacity of bus :
Number of children = 30
Number of Adult = 24
Comparing the number of adult to children
Number of adults : number of children
24 : 30
4 : 5
If 25 children are already in the bus ; number of adults who can still get in the bus will be ;
Number of children left to reach maximum capacity = (30 - 25) = 5
Number of adults = [(Ratio of adult to children) * Number of children left]
Number of adults = (4/5) * 5 = 20/5 = 4
Hence, 4 adults can still get on the bus
