Answer: Ann = 67 Josh = 60 Claire = 30

Step-by-step explanation: You get the equation 5x+7 = 157. You get the equation because for example, Claire = x then josh = 2x and Ann = 2x + 7. You do all the math and boom! You get the answer :)

The number of stickers collected are:

Ann = 67

Claire = 30

Josh = 60

Given,

Ann, Claire, and Josh collect stickers.

One week, Ann collects 7 more stickers than Josh.

Josh collects twice as many stickers as Claire.

Total tickets collected = 157 stickers.

We need to find out how many stickers each collected.

Let the tickets collected by Ann, Claire, and Josh be A, C, and J.

We can write the following equation:

Ann collects 7 more stickers than Josh.

A = 7 + J _______(1)

Josh collects twice as many stickers as Claire.

J = 2C_______(2)
Total tickets collected = 157 stickers.

A + C + J = 157 ______(3)

Solve the equation (1), (2), and (3).

A = 7 + J _____(1)

J = 2C  _______(2)

A + C + J = 157 ______(3)

Put J = 2C in A = 7 + J

A = 7 + 2C ______(4)

Put (2), (4) in (3)

7 + 2C + C + 2C = 157

7 + 5C = 157

Subtracting 7 on both sides.

7 + 5C - 7 = 157 - 7

5C = 150

Dividing both sides by 5.

C = 30

Putting C = 30 in J = 2C

J = 2x30 = 60

J = 60

Putting J = 60 in A = 7 + J

A = 7 + 60

A = 67

Thus the number of stickers collected are:

Ann = 67

Claire = 30

Josh = 60

Answer/Step-by-step explanation:

Using [tex] f(x) = 3x^2 - 8x + 2 [/tex], simply plug each value of x into the function to get f(x) values.

Thus, when x = -1

[tex] f(-1) = 3(-1)^2 - 8(-1) + 2 [/tex]

[tex] f(-1) = 3*1 + 8 + 2 = 3 + 8 + 2 [/tex]

[tex] f(-1) = 13 [/tex]

[tex] f(0) = 3(0)^2 - 8(0) + 2 [/tex]

==============================================

Work Shown:

1/10 = 0.1

0.1 mile = 7.2 seconds

1 mile = 72 seconds (multiply both sides by 10)

1/72 mile = 1 second (divide both sides by 72)

3600/72 = 3600 seconds (multiply both sides by 3600)

50 miles = 3600 seconds

50 miles = 1 hour

The car's speed is 50 mph

Answer:

Total cost of producing is 2800.

Step-by-step explanation:

Given

Ratio of profit, material cost and production labour is 5:7:13.

Material cost is 840 more than that of labour cost.

To find:

Total cost of producing the article.

Solution:

Cost of producing the article includes material cost and the labour cost.

Profit will not be included in the production cost because profit comes in the picture after the article is sold.

We are given that, the ratio is:

Profit: Material Cost: Production Labour = 5:7:13

So, we can let Material Cost = 7[tex]x[/tex] and

Production Labour = 13[tex]x[/tex]

As per the question statement:

[tex]13x-7x=840\\\Rightarrow 6x=840\\\Rightarrow \bold{x=140}[/tex]

Total cost of producing = Material Cost + Production Labour

Total cost of producing = 7[tex]x[/tex] + 13[tex]x[/tex] = 20[tex]x[/tex] = 20 [tex]\times[/tex] 140 = 2800

So, Total cost of producing is 2800.

Answer and explanation:

Benchmark fractions are fractions that are used as references in measuring other fractions. They are easily estimated and so can be used in measuring more "specific" fractions such as 1/5, 7/9, 3/7, 1/3 etc. If I wanted to measure 1 1/3cm for instance using a calibrated ruler, having centimeter measurements, I would first find 1cm on the ruler and then find half of one centimeter. Seeing that half is bigger than 1/3 but close, I could then estimate 1/3 to be somewhere less than 1/2 but a bit close to it

Step 1: Simplify both sides of the equation.

[tex]2(3x+6)=3(x-9)[/tex]

[tex](2) (3x) + (2) (6) = (3)(^{x}) + (3) (-9)[/tex] (Distribute)

[tex]6x + 12 = 3x -27[/tex]

Step 2: Subtract 3x from both sides.

[tex]6x + 12 - 3x = 3x - 27 - 3x\\3x + 12 = -27[/tex]

Step 3: Subtract 12 from both sides.

[tex]3x + 12 - 12 = -27 - 12\\3x = -39[/tex]

Answer:

10 Ships

Step-by-step explanation:

Khan Academy

The number of ships Astrid can build is 10, assuming she receives the maximum possible amount of wood.

Multiplication is one of the four basic arithmetic operations, alongside addition, subtraction, and division. In math, multiply means the repeated addition of groups of equal sizes.

Given that:

Astrid receives a delivery of 4 tons of wood each day.

The deliveries can continue for 100 days at most.

At most, she received amount of wood = 4 × 100 tons = 400 tons.

Each ship requires 40 tons of wood.

Number of  ships required = (400÷40) = 10.

Each ship  accommodates 300 sailors.

She have  to build enough ships to accommodate = (300 × 10) = 3000 sailors.

Again, she wants to build enough ships to accommodate at least 2100 sailors.

As 3000>2100;  the number of ships Astrid can build is 10.

Answer:

The missing side is 8 ft long

Step-by-step explanation:

According to Pythagoras theorem "It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides"

mathematically it is stated as

[tex]c^2= a^2+b^2\\\\c=\sqrt{a^2+b^2}[/tex]

Given that

c, hypotenuse= 17 ft

a = 15 ft

b= ?

Applying the Pythagoras theorem formula by inserting our given parameters and solving for b we have

[tex]17^2= 15^2+b^2[/tex]

Making b subject of formula we have

[tex]b^2= 17^2-15^2\\\\b^2= 289-225\\\\b^2= 64\\\\[/tex]

Square root both sides we have

[tex]b= \sqrt{64} \\\\b= 8[/tex]

Answer:

[tex]f'(x) = 3-2\cdot x[/tex]

Step-by-step explanation:

Let be [tex]f(x) = -x^{2}+3\cdot x[/tex], such that:

[tex]f'(x) = \frac{f(x+h)-f(x)}{h}[/tex]

Hence,

[tex]f(x+h) = -(x+h)^{2}+3\cdot (x+h)[/tex]

[tex]f(x+h) = -(x^{2}+2\cdot x\cdot h + h^{2})+3\cdot x + 3\cdot h[/tex]

[tex]f(x+h) = -x^{2}+(3-2\cdot x) \cdot h - h^{2}+3\cdot x[/tex]

[tex]f(x) = -x^{2}+3\cdot x[/tex]

Then,

[tex]f'(x) = \frac{-x^{2}+(3-2\cdot x)\cdot h-h^{2}+3\cdot x+x^{2}-3\cdot x}{h}[/tex]

[tex]f'(x) = \frac{(3-2\cdot x)\cdot h-h^{2}}{h}[/tex]

[tex]f'(x) = 3-2\cdot x -h[/tex]

If [tex]h \longrightarrow 0[/tex], then:

[tex]f'(x) = 3-2\cdot x[/tex]

The line of y=x-2 intersects the x axis at (2,0).

To find the points where line intersect the x-axis.

Coordinate geometry is defined as the study of geometry using the coordinate points. Coordinate geometry is required to provide a link between algebra and geometry through the use of line and curve graphs.

The x-axis is defined as being at y=0 (look at a graph, the x-axis intersects the y-axis at y=0). Therefore, all you need to do is put in 0 for y, and solve for x.

  y=x-2

 put in 0 for y

 0=x-2

add 2 to both sides

2+0=x-2 +2  

 x=2

Therefore the line of y=x-2 intersects the x axis at (2,0).

Answer:

Hey there!

The question is basically asking for you to solve a fraction subtraction problem, and fill in the missing values as you solve.

The given problem is 2/3 - 1/2. However, we can't subtract right now, since the denominators are different.

2/3 can be expressed as 4/6, and 1/2 can be expressed as 3/6.

Thus, the missing denominator in line one is 6 and the missing numerator in line one is 3.

4/6-3/6=1/6.

Thus, the numerator in line two should be 1.

From top to bottom, the numbers in the three boxes should be 6, 3, and 1.

This can be a confusing topic, especially if you're just learning it. Let me know if you need additional help :)
