Need help with this Geometry

Answer:

Explanation:

Area = width · length

The length of the rug is 9 feet. We need to find the width.

72 ÷ 9 = 8

Check to see if this is correct: width (8) · length (9) = area (72)

Now add the length and width together two times since a rug has 4 sides

8 + 8 + 9 + 9 = 34

The perimeter of the rug is 34 ft.²

To solve the problem we will firstly rearrange the given expressions to get like terms together.

like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

If we subtract 9x^2+7x-2 from 8x−10, then we will get [tex]-9x^2 +x -8[/tex].

Given to us

we know to subtract an expression from another we need to find the like terms of both expressions to carry out the mathematical operation.

therefore,

[tex](8x-10) - (9x^2+7x-2)\\\\=8x-10 - 9x^2-7x+2\\\\= -9x^2 +8x-7x-10+2\\\\= -9x^2 +x -8[/tex]

Hence, if we subtract 9x^2+7x-2 from 8x−10, then we will get [tex]-9x^2 +x -8[/tex].

Step-by-step explanation:

Answer:

x = -4/5, y = 13/20

Step-by-step explanation:

-10x + 4 = 12

-10x = 8

x = -4/5

3x - 4y = -5

3(-4/5) - 4y = -5

-12/5 - 4y = -5

-4y = -13/5

y = 13/20

Double check:

3x - 4y = -5

3(-4/5) - 4(13/20) = -5

-12/5 - 13 = -5 (true)

Answer:

Step-by-step explanation:

Let's solve your system by substitution.

32=4(n−5);−s+11=17

Rewrite equations:

32=4n−20;−s+11=17

Step: Solve 32=4n−20 for n:

32=4n−20

32+−4n=4n−20+−4n(Add -4n to both sides)

−4n+32=−20

−4n+32+−32=−20+−32(Add -32 to both sides)

−4n=−52

−4n/ −4 =/ −52/ −4

(Divide both sides by -4)

n=13

Step: Substitute 13 for n in  −s+11=17:

−s+11=17

−s+11=17

−s+11+−11=17+−11(Add -11 to both sides)

−s=6

−s/ −1 = 6/ −1

(Divide both sides by -1)

s=−6

Answer:

n=13 and s=−6

Answer:

[tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins

Step-by-step explanation:

The computation is shown below:

Nuts used [tex]= 5 \frac{1}{3} = \frac{16}{3}[/tex]

Raisins used [tex]= 2 \frac{3}{4} = \frac{11}{4}[/tex]

Now the difference between them is

[tex]= \frac{16}{3} - \frac{11}{4}\\\\= \frac{64 - 33}{12} \\\\= \frac{31}{12}[/tex]

Hence, [tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins

Answer:

109 divided by 12 is about 9.3 carton thingys so she would most likley sell 8

so she can keep some

Step-by-step explanation:

The farmer sells 6 cartoons.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total Eggs= 109

A carton contain= 12 eggs

If the farmer takes away 13 eggs, the eggs left

= 109 - 13

= 96 eggs.

So, the number of cartoons will famer sell

= 96 / 12

= 6 cartoons.

Hence, the farmer sells 6 cartoons.

The function is [tex]y = 40x + 350[/tex]

When he sold 30 cellphones, he earned $1550.

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope(how much y changes when x changes by 1), and b is the y-intercept, that is, the value of w when x = 0.

Base salary of $350 each month and earns an additional $40 for each cellphone he sells.

If he sells 0 cellphones, he earns $350, so [tex]b = 350[/tex].

For each cellphone he sells, he earns $40, so [tex]m = 40[/tex]

The function is:

[tex]y = mx + b = 40x + 350[/tex]

Tomas' earnings for a month where he sold 30 cellphones.

This is y when [tex]x = 30[/tex]. So

[tex]y = 40*30 + 350 = 1550[/tex]

When he sold 30 cellphones, he earned $1550.
