Step-by-step explanation:

Answer:

(x, y) = (-1, 6)

Step-by-step explanation:

y = 2x + 8

y = 5 - x

Substituting the second equation into the first equation, we get:

5 - x = 2x + 8

5 = 3x + 8

-3 = 3x

x = -1.

So, y = 5 - (-1).

Simplifying, we get:

y = 6.

Answer:

sin x= opp/hyp

sin x=18/30

sin x =3/5

cos x= adj/hyp

cos x=24/30

cos x=4/5

tan x=opp/adj

tan x=18/24

tan x=3/4

Answer:

You can use distance formula,

i. e. underroot (x sub2 - x sub1 )^ 2 - (y sub2 - y sub1 )

where u take first point as x sub1 and x sub2

and,

take second point as y sub1 and y sub2

where,

sub = subscript

Answer: Johann Heinrich Rahn

It was introduced by the Swiss mathematician, Johann Heinrich Rahn, in his work Teutsche Algebra (1659). This symbol was not much of a success in his home country of Switzerland or in Europe. But however, it was in both the Britain and also the USA.

Answer:

2x+4y= 24

x≥3

y≤2

Step-by-step explanation:

Given data

total expenses= $24

let the number of tickets be x

and the number of rides be y

Tickets cost $2 each, and ride tickets cost $4

Hence the expression for the situation is given as

2x+4y= 24

x≥3

y≤2

Answer:

1/3 pies per person

Step-by-step explanation:

there are 6 people who gets served.

2 pies / 6 people = 1/3 pies per person

Answer:

2/6 = 1/3

She has 5 visitors + herself=6

Six people share 2 pies

She'll have to cut each pie into 3 equal pieces

So everyone will get a third of an apple

That is 1/3

Answer:

-12

Step-by-step explanation:

Answer:

1st one: 270 ft ^2

2nd: 30 square yards

Step-by-step explanation:

The first one you have to find the area. 15×18= 270

The second one you take the previous answer and divide by 9= 30 square yard. (Might be wrong?)

Answer:

6x-12=-48

6x=-36

x=-6

Step-by-step explanation:

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

Work Shown:

1/4 = 0.25

7/10 = 0.70 = 70%

We are told that 0.25 gallons of water fills 70% of the pool

We want to find how many gallons of water (call it x) are needed to fill 100% of the pool.

Set up the proportion below and solve for x

(0.25 gallons)/(70% filled) = (x gallons)/(100% filled)

0.25/70 = x/100

0.25*100 = 70x ....... cross multiply

25 = 70x

70x = 25

x = 25/70

x = (5*5)/(5*14)

x = 5/14 gallons

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

An alternate method:

1/4 gallons = 7/10 pools filled

(10/7)*(1/4 gallons) = (10/7)*(7/10 pools filled)

(10*1)/(7*4) gallons = (10*7)/(7*10) pools filled

10/28 gallons = 1 pool filled

(5*2)/(14*2) gallons = 1 pool filled

5/14 gallons = 1 pool filled

In the second step, I multiplied both sides by 10/7 so that the "7/10" turns into "1".

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

Yet another alternate method:

1/4 = 10/40

7/10 = 28/40

We need 10/40 gallons of water to fill 28/40 of one pool. We can multiply both fractions by 40 to indicate that 10 gallons of water will fill up 28 pools.

So we have this ratio

10 gallons : 28 pools

Dividing both parts by 28 tells us how many gallons are needed for one pool

10 gallons : 28 pools

10/28 gallons : 28/28 pools

10/28 gallons : 1 pool

5/14 gallons : 1 pool

Answer:

[tex] m\angle A = 40\degree[/tex]

Step-by-step explanation:

[tex]m\angle A = \frac{1}{2} (115 \degree - 35 \degree) \\ \\ m\angle A = \frac{1}{2} \times 80\degree \\ \\ m\angle A = 40\degree \\ \\ [/tex]

Answer:

8(3y + 2) = 8 * 3y + 8 * 2 = 24y + 16

Step-by-step explanation:

The outer rectangle has width 8 and length 3y + 2.

The area of the outer rectangle is length times width or width times length, so the area is 8(3y + 2).

We can also find the area by finding the area of each small rectangle, and adding the areas together.

The left small rectangle has dimensions 8 and 3y.

A1 = WL = 8 * 3y = 24y

The right small rectangle has dimensions 8 and 2.

A2 = WL = 8 * 2 = 16

The total area of both small rectangles is 24y + 16

That tells use that

8(3y + 2) = 8 * 3y + 8 * 2 = 24y + 16

This is the distributive property at work.

Answer:

5s+7.6 is already simplified

Step-by-step explanation:

Hope I answered your question correctly:)

Given :

On a farm, 4 and half out of every 15 acres of the land are used to grow crops.

Wheat is grown on 5/8 of the land used to grow crops.

To Find :

The total area of the land on the farm is used to grow wheat.

Solution :

Land required to grow crops on every 15 acres is :

C = 4.5 or C = [tex]\dfrac{9}{2}[/tex] acres.

Now, it is given that wheat is grown on [tex]\dfrac{5}{8}[/tex] of the land used to grow crops.

[tex]W = \dfrac{9}{2}\times \dfrac{5}{8}\\\\W = \dfrac{45}{16}\ acres[/tex]

Now,  percentage of the total area of the land on the farm is used to grow wheat is :

[tex]\% W = \dfrac{45}{16\times 15 }\times 100\\\\\%W = 18.75 \%[/tex]

Hence, this is the required solution.

Answer:

M=15

J=20

Step-by-step explanation:

Let J and M be the present age of John and Mary respectively:

J=M+5

2(J+10)−(M+10)=35

2(M+5+10)−(M+10)=35

2M+30−M−10=35

M=15

J=20
