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

Answer: 15.3 miles

Step-by-step explanation:

From the question, we are informed that Martin would like to start training to run a marathon and that first week he runs a total of 15 miles.

We are further told that he would like to run 0.3 more miles each week than the week before. There, the number of miles that Martin will run the second week will be:

= 15 miles + 0.3 miles

= 15.3 miles

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

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

Answer:

3 mi and [tex]\dfrac{4}{3}[/tex] mi, 1 mi and 4 mi

Step-by-step explanation:

Length of one of rectangles = x

Breadth of one of the rectangles = y

Total enclosed area = [tex]8\ \text{mi}^2[/tex]

Fence available = 16 miles

Total area is given by

[tex]2xy=8\\\Rightarrow y=\dfrac{4}{x}[/tex]

Perimeter of the fence

[tex]2\times 2x+3y=16\\\Rightarrow 4x+3y=16\\\Rightarrow 4x+3\dfrac{4}{x}=16\\\Rightarrow 4x+\dfrac{12}{x}=16\\\Rightarrow 4x^2-16x+12=0\\\Rightarrow x=\frac{-\left(-16\right)\pm \sqrt{\left(-16\right)^2-4\times \:4\times \:12}}{2\times \:4}\\\Rightarrow x=3,1[/tex]

If [tex]x=3[/tex]

[tex]y=\dfrac{4}{x}=\dfrac{4}{3}[/tex]

If [tex]x=1[/tex]

[tex]y=\dfrac{4}{x}=4[/tex]

The possible values of length and breadth are 3 mi and [tex]\dfrac{4}{3}[/tex] mi, 1 mi and 4 mi respectively.

Step-by-step explanation:

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:

neither

Step-by-step explanation:

look at the image

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)

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

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

Answer:

1.1

Step-by-step explanation:

[tex] \frac{ \sqrt{121} }{ \sqrt{25} \times \sqrt{4} } = \frac{11}{5 \times 2} = \frac{11}{10} = 1.1[/tex]

Answer:

a= -2     b =4

Step-by-step explanation:

I put it in a calculator and found the answer

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.

Answer:5/9

Step-by-step explanation:

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55

Answer:
