Answer:

x > 7

Step-by-step explanation:

-3 < x - 10

Subtract x from both sides.

-x - 3 < -10

Add 3 to both sides.

-x < -7

Divide both sides by -1. Remember that when you multiply or divide both sides of an inequality by a negative number, the inequality sign changes direction.

x > 7

Answer:

For this case Mr Doyle nees to cut his rectangular lawn and we assume that all the place is covered by lawn so then we need to find the area.

[tex]A = 23ft* 25 ft = 575 ft^2[/tex]

So then Mr Doyle need to mow 575 ft^2 in order to finish the job

Step-by-step explanation:

For this case Mr Doyle nees to cut his rectangular lawn and we assume that all the place is covered by lawn so then we need to find the area.

And the area for a rectangular shape is given by:

[tex] A = lw[/tex]

Where l is the length and w the width. If we replace the info given we got:

[tex]A = 23ft* 25 ft = 575 ft^2[/tex]

So then Mr Doyle need to mow 575 ft^2 in order to finish the job

Answer:

[tex]A = 23ft\times25 ft \\\\= 575 ft^2[/tex]

Mr Doyle need to mow [tex]575 ft^2[/tex] in order to mow the entire lawn

Step-by-step explanation:

Mr. Doyle needs to mow his rectangular lawn that measures 23 x 25 square feet.

we will have to find the area.

And the area for a rectangular lawn is Length * Breadth

A = L * B

Where l is the length and B is the width.

L = 23 square feet

B = 25 square feet

By inputting the values we get,

[tex]A = 23ft\times25 ft \\\\= 575 ft^2[/tex]

Therefore, Mr Doyle need to mow [tex]575 ft^2[/tex] in order to mow the entire lawn

The expression is 5 + 2n.

Declaration that the sum of a set of terms, each of which is the product of a constant and the first power of a variable, is equal to a constant in a first-degree polynomial (also known as a linear equation).

A system of simultaneous equations is an ensemble of equations that share a common solution.

Given a sentence "five plus two times a number"

let a number be n

two times of number = 2 x n = 2n

and add 5 we get,

5 + 2n

Hence the expressions represent the phrase is 5 + 2n.

Step-by-step explanation:

Given the sequence:

b(n)=b(n−1)−7, where b(1)=−2

b(2)=b(2−1)−7

=b(1)−7

=-2-7

b(2)=-9

Therefore, the 3rd term of the sequence

b(3)=b(3−1)−7

=b(2)-7   (Recall b(2)=-9 from above)

=-9-7

b(3)=-16

The 3rd term of the sequence is -16.

Answer:

11.65 km / day

Step-by-step explanation:

We can calculate the amount of daily kilometer in the following way

First day: 2 * 6 = 12 km

Second day: 1.5 * 6 = 9 km

Third day: 1.333 * 6 = 8 km

Fourth day: 2.4 * 6 = 14.4 km

Sixth day: 1.666 * 6 = 10 km

on Saturday: 2.75 * 6 = 16.5 km

the average per day

(12 + 9 + 8 + 14.4 + 10 +16.5) / 6 = 11.65

11.65 km/day

I think the answer is C

Step-by-step explanation:

If you have a normal ginger bread cookie, its full size would be 100%. So, if you add the first 25%, 1.25%

The expression best describes the new length of the cookie will be 1.25y.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Given that:-

The initial length of the cookie is y after baking the length is increased by 25%

=   y  +  25%y

=   y   +  ( 25 / 100 ) y

=   y  +  0.25 y

=  1.25 y

Therefore the expression best describes the new length of the cookie will be 1.25y.

Answer: (x+4)^2 + (y-1)^2 = 162

Step-by-step explanation:

Equation of Circle : (x – h)^2 + (y – k)^2 = r^2

(h, k) is the center of the circle, r is the radius

The center is (-4, 1), plug it in to get:

(x+4)^2 + (y-1)^2 = r^2

To find the radius we can use the distance formula to find the distance between C and P:

Distance Formula: d = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]

Plug in C: (-4, 1) and P:(5, -8) to get [tex]\sqrt{162}[/tex]

So, the equation is:

(x+4)^2 + (y-1)^2 = [tex]\sqrt{162} ^{2}[/tex]

(x+4)^2 + (y-1)^2 = 162

16.8 = 2.4 e

=> e = 16.8/2.4

=> e = 168/24

=> e = 7

Hence, E equal to 7

Answer:

e = 7

Step-by-step explanation:

2.4e is the same as [tex]2.4*e[/tex], so you simply undo the equation.

[tex]16.8=2.4*e[/tex]

divide by 2.4 on both sides to isolate the variable.

[tex]16.8/2.4 = (2.4 *e)/2.4[/tex]

Answer:

The answer is 61:)

Step-by-step explanation:

The concept distance formula is used here to determine the distance between two points. The distance between two points is the length of the line joining the two points. The distance between point X and point Y is  4√2 units.

In analytical geometry, the distance formula is used to find the distance measure between two lines. The distance between two points of the xy-plane can be found using the distance formula.

The distance between two points is given as:

d = √(x₂ - x₁)² + (y₂ - y₁)²

d = √(-1 + 5)² + (3 - 7)²

d = √(4)² + (-4)² = √16 + 16

d = 4√2 units

Thus the distance between two points X(-5,7) and Y(-1,3) is  4√2 units.

As a mixed number: [tex]1 \frac{4}{11}[/tex]

As a decimal: 1.36

Step-by-step explanation:

[tex]3/5x - 1/3x = x - 1[/tex]

Find a common denominator between 5 and 3 (15)

[tex](3 * 3) / 15x - (1 * 5) / 15 = x - 1[/tex]

[tex]9/15x - 5/15 = x - 1[/tex]

Subtract the fractions

[tex]4/15x = x - 1[/tex]

Subtract x from both sides of the equation

[tex]-11/15x = -1[/tex]

Multiply both sides of the equation by 15/-11 to simplify

x = 15/11

Hope this helps :)

Answer:

Exact Form:

x  =  15/11

Decimal Form:

x  =  1.36

Mixed Number Form:

x  =   1(4)/(11)

Step-by-step explanation:

(3)/(5)x-(1)/(3)=x-1

Simplify  (3)/(5)x-(1)/(3)x

(4x)/(15)=x-1

Move all terms containing  x  to the left side of the equation.

-(11x)/(15)=-1

Multiply both sides of the equation by    -(15)/(11)

-(15)/(11)(-(11)/(15))= -(15)/(11) . -1

Simplify both sides of the equation.

(15)/(11)
