How do depict the information?

Based on the information given, the values of the coins will be 5p, 5p, 10p, 15p, and 15p.

In this case, 5p + 10p + 15p = 30p

10p + 15p + 15p = 40p

5p + 5p + 10p + 15p + 15p = 50p

Therefore, Tony's coins in ascending order of value will be 5p, 10p, and 15p.

Answer: y = 2(x + 2)² - 5

Step-by-step explanation:

          We are going to use the completing the square method to transform this quadratic equation from standard form to vertex form.

Given:

     y = 2x² + 8x + 3

Factor the 2 out of the first two terms:

     y = 2(x² + 4x) + 3

Add and subtract \(\frac{b}{2} ^2\):

     y = 2(x² + 4x + 4 - 4) + 3

Distribute the 2 into -4 and combine with the 3:

     y = 2(x² + 4x + 4) - 5

Factor (x² + 4x + 4):

     y = 2(x + 2)² - 5

Answer:

60 = n

Step-by-step explanation:

This problem can be rewritten as:

18 is 30% of what?

% means "out of 100" and of means "multiply"

18 = 30/100 ⋅ n

100/30 ⋅ 18 = 100/30 ⋅30/100 ⋅ n

1800/30 = 100/30 ⋅ 30/100 ⋅ n (both the 30/100 and 100/30 are crossed out here)

Answer:

Step-by-step explanation:

You set f(x) = 9 and solve from there.

9 = 4x - 7

+7         +7

16 = 4x

/4     /4

x = 4

Answer:

The answer is 4

Step-by-step explanation:

f(x)=4x-7

f(x)=9

9=4x-7

9+7=4x-7+7

(the -7 and the +7 cancel out, and remember: whatever you do the one side you have to do to the other)

16=4x

(divide by 4 to isolate x and do the same to the other side of the equation so you get the answer)

so, x=4

Answer:

See below.

Step-by-step explanation:

We can represent Imani's weekly allowance with the variable a. The equation you can write is:

1/2a+4=12

2(1/2a+4)=2(12)

a+8=24

a=16

The Imani's weekly allowance value is $16.

To solve this problem using a two-step equation,  follow these steps:

Step 1: Let's represent Imani's weekly allowance with the variable "x."

Step 2: We know that Imani spent half of her allowance playing mini-golf, so the amount she spent is (1/2) × x. Additionally, she earned $4 by washing the car. Therefore, the equation becomes:

x - (1/2) × x + 4 = 12

To solve this equation, we need to combine like terms and isolate the variable "x":

(1/2) ×x = 12 - 4

(1/2) × x = 8

Next multiply both sides of the equation by 2 to eliminate the fraction:

2 × ((1/2) × x) = 2 × 8

x = 16

Answer:

9ft

Step-by-step explanation:

14 ft (top) - 5ft (bottom) = missing side (which is 9ft)

Answer:

9ft

Step-by-step explanation:

suppose that the side of 7ft was dragged to the right till it meets the side of 4ft

and the unknown side was dragged downwards till it meets the side of 5ft

Then, also considering that all angles are right angles, this structure becomes a square.

So the answer is 14ft - 5ft = 9ft

y = 15.6 - 3.8x

y = 15.6 - 3.8*3

y = 4.2

Answer:

x=5, y=1

Step-by-step explanation:

Isolate x for 5x-3y=22

5x-3y=22

Add 3y to both sides

5x-3y+3y=22+3y

Simplify

5x=22+3y

Divide both sides by 5

5x/5=22/5+3y/5

Simplify

x=22+3y/5

Substitute  x=22+3y/5

10*22+3y/5-4y=46

Simplify 10*22+3y/5-4y

10*22+3y/5=2(3y+22)

=2(3y+22)-4y

Expand 2(3y+22)

=6y+44-4y

Simplify 6y+44-4y

=2y+44

Isolate y for 2y+44=46

2y+44=46

Subtract 44 from both sides:

2y+44-44=46-44

Simplify

2y=2

Divide both sides by 2;

2y/2=2/2

Simplify;

y=1

For x=22+3*1/5 substitute y=1

y=22+3*1/5

22+3*1=25

=25/5

Divide the numbers;25/5=5

An algebraic expression is a mathematical phrase that contains numbers, variables, and operations. It is used to represent a single quantity or value, and can be written in terms of one or more variables.

The rule given is an algebraic expression, x, which is the input, multiplied by 2.85, which is the output. Using this information, we can determine the cost of 10 muffins.

To find the cost of 10 muffins, we can use the algebraic expression given. First, we will multiply 10, the number of muffins, by 2.85, the cost of one muffin. This gives us a total of 28.50. Therefore, the cost of 10 muffins is 28.50.

Using this same rule and process, we can also determine the cost of any number of muffins. For example, if we want to know the cost of 15 muffins, we can simply multiply 15 by 2.85, giving us a total of 42.75.

Between Method A with a MAD(Mean Absolute Deviation) of 1.4 and Method B with a MAD (Mean Absolute Deviation) of 1.8, Method A performed better as it has a smaller MAD value.

To decide which estimating strategy performed the leading, we got to compare their Mean Absolute Deviation (Mad) values. Mad may be a degree of the average outright contrast between the genuine values and the forecasted values.

A little Mad esteem shows distant better; a much better; a higher; stronger; an improved" an improved forecasting accuracy, because it implies the forecasted values are closer to the real values.

Hence, between Strategy A with a Mad of 1.4 and Strategy B with a Mad of 1.8, Strategy A performed way better because it incorporates littler Mad esteem.

Answer:

Find the ratio of hops to distance traveled (1: 1.5), then multiply 150 by 1.5.

Step-by-step explanation:

A child is hopping along a sidewalk. The ratio table below shows the comparison between the number of hops and the distance traveled. Hopping Number of hops Distance traveled (ft) 20 30 50 75 80 120 150 ?

Which statement correctly explains how to find the distance traveled after 150 hops? Subtract 120 – 75 to get 45, then add that number to 120. Add 30 + 75 + 120. Find the ratio of hops to distance traveled (1:1.5), then multiply 150 by 1.5. Find the ratio of hops to distance traveled (1:1.5), then divide 150 by 1.5.

Solution:

The table is:

No. of hops Distance traveled

20 30

50 75

80 120

150 ?

From the table, for every 30 increase in the number of hops, the distance travelled increase by 45 feet

Find the slope of the line:

m = (y2-y1) / (x2-x1)

m=slope of the line

y2-y1 = change in distance travelled

x-2 - x1 = Change in number of hops

m = (y2-y1) / (x2-x1)

m = (75-30) / (50-20)

=45 / 30

m = 1.5

Then, the line is:

y = 1.5x

We substitute x = 150

y = 1.5x

y = 1.5 × 150

y = 225

Answer:

x=13

Step-by-step explanation:

By completing the square we can see that the correct option is A:

(x - 5)² = 36

To get this, we need to complete squares.

Rememeber the perfect square trinomial:

(a + b)² = a² + b² + 2ab

The given quadratic equation is:

x² -10x  -11  = 0

We can rewrite that as:

x² - 2*5*x - 11 = 0

Now we can add and subtract 5² = 25 in both sides, then we will get:

(x² - 2*5*x + 5²) - 11 = 5²

(x - 5)² - 11 = 25

(x - 5)² = 25 + 11 = 36

(x - 5)² = 36

The correct option is A.
