Seven less than a number is 18

Answer:

-8

Step-by-step explanation:

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)

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:

Let 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: 110 degrees

Step-by-step explanation:

30+40=70

180-70=110

Answer: 45

Step-by-step explanation:

59 + 76= 135

180-135= 45

Answer:

m∠1 = 45 degrees

Step-by-step explanation:

All triangles have the interior angle of 180

to find the missing angle, take the known angles and add them together:

76 + 59 = 135

then take the sum and subtract it from 180:

180 - 135 = 45

Answer:

£ 5400

Step-by-step explanation:

P = £ 7500

r = 12% = 0.12

t = 6 years

Simple Interest = P*r*t

                         = 7500 * 0.12 * 6

                         = £ 5400

Answer:

Answer:

x  <= 8 ... you can buy a max of 8 fishes

6 books or more per month.

Step-by-step explanation:

Given the information provided, we can create the following inequality which multiplies the cost per fish ($7) by the number of fish we can buy (x) and it has to be less than or equal to $56

7x <= 56

We can now solve this inequality by isolating x

7x <= 56  ... divide 7 on both sides

x  <= 8   ... you can buy a max of 8 fishes

-----------------------------------------------------------------------------------------------------------------

13x > 68  ... divide both sides by 13

x > 5.23

Since the number of books needs to be a whole number then we round this decimal up to 6. Meaning that you must read 6 books or more per month.

Answer:

25% is left

Step-by-step explanation:

12oz is how much is consumed and 16-12+4 so 4oz remain and to convert that to a percent you do 4 divided by 16 which is 0.25 and to get the present age you multiple 0.25 by 100 to get 25% left

The percentage of Dutch Bros left is 25%.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, You drank 12 ounces of your 16 ounce Dutch Bros.

Here, percentage left = Difference in ounce of Dutch Bros/Total quantity of Dutch Bros ×100

= (16-12)/16 ×100

= 4/16 ×100

= 25%

Therefore, the percentage of Dutch Bros left is 25%.

Step-by-step explanation:

The radius of the larger circle is 12 inches. Then the area of the larger circle will be 144π square inches.

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

The four small circles are identical. The total area of the small circles is 36π square inches. Then the radius of each small circle is given as,

36π = 4 × (πr²)

r² = 9

r = 3 inches

Then the radius of the larger circle is calculated as,

R = 4r

R = 4 × 3

R = 12

Then the area of the larger circle will be given as,

A = π × (12)²

A = 144π square inches

The radius of the larger circle is 12 inches. Then the area of the larger circle will be 144π square inches.

Answer:

y= -2x +2

Step-by-step explanation:

The equation of a line can be written in the form of y= mx +c, where m is the gradient and c is the y-intercept. This form is known as the slope-intercept form.

To find the value of m, use the gradient formula below:

[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]

[tex]m = \frac{6 - ( - 4)}{ - 2 - 3}[/tex]

[tex]m = \frac{6 + 4}{ - 5} [/tex]

[tex]m = \frac{10}{ - 5} [/tex]

m= -2

Substitute m= -2 into the equation:

y= -2x +c

To find the value of c, substitute any pair of coordinates that the line passes through into the equation. Here, I am going to substitute the coordinates (3, -4).

y= -2x +c

When x= 3, y= -4,

-4= -2(3) +c

-4= -6 +c

c= -4 +6

c= 2

Thus, the equation of the line is y= -2x +2.

The inequality that represent the heights of the mountains in the given range is h < 20,000

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.

Given that, the heights of the mountains in a mountain range are less than 20,000 feet.

We need to write an inequality to represent the height of the mountain ranges,

Since, the height is less than 20,000,

Therefore, the inequality =

h < 20,000

Hence, the inequality that represent the heights of the mountains in the given range is h < 20,000

Answer: $5

Step-by-step explanation:

Let the small candy be represented by x.

The medium candy was twice as expensive as the small candy. This will be: = 2×x = 2x

The large candy was $5 more than the medium candy. This will be: = 2x + 5

Since Jason spent a total of $30 on

candy, the cost of the small candy will be:

x + 2x + 2x + 5 = 30

5x + 5 = 30

5x = 30 - 5

5x = 25

x = 25/5

x= 5

The small candy cost $5

Answer:

2.2% per year

Step-by-step explanation:

Problem:

You deposit $500 into a bank account and received $55 simple interest after 5 years. What had been the interest rate?

Result:

The interest rate was 2.2% per year.

Explanation:

Find interest rate by using the formula I = P*i*t , where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.  In this example I = $55, P = $500 and t = 5 years, so

i = 55/500*5

i=0.022 = 2.2% per year

Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments. If you drag any of the four endpoints, the other segment will change length to remain congruent with the one you are changing.
