Answer:

p = 2

Step-by-step explanation:

Since, (2p-1,p) is a solution of the equation 9y + 12 = 10x.

Therefore, plug x = 2p - 1 & y = p in the above equation.

9p + 12 = 10(2p - 1)

9p + 12 = 20p - 10

12 + 10 = 20p - 9p

22 = 11p

p = 22/11

p = 2

Answer:There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?

Step-by-step explanation

There are 72 heads (chicken and rabbit) and 200 legs. How many chickens and rabbits are present totally?

Legs of a chicken = 2

Legs of a rabbit = 4

Total heads = 72

Total legs= 200

Let's assume that each of them has minimum 2 legs.

So 72*2 = 144 legs

Remaining legs: 200-144= 56

These remaining legs belong to rabbit because rabbit has 4 legs each.

2*Rabbits= 56

Rabbits= 56/2 = 28

Out of 72, 28 are rabbits. So there are 72-28= 44 chicken.

Answer:

3n - 17

Step-by-step explanation:

This phrase includes subtraction (“less than”) and multiplication (“times”). We are multiplying a number (3) by the variable to create the term 3n. Subtraction is not commutative, so order does matter. 17 less than 3n means we have 3n and take 17 away: 3n - 17.

C. x = 1.5y

Answer: 120

Step-by-step explanation:

Let x be the amount of money to be shared

Paul’s share which is (3/5)x is 60+ Quinn’s share which is (2/5)x

Therefore

(3/5)x= (2/5)x + 60

(3/5)x - (2/5)x= 60

(x/5)=60

Cross multiply

x= 60*5=300

It means that Quinn’s share is (2/5)(300)= 120

The amount of money that Paul and Quinn have will be $180 and $120, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Paul and Quinn share some cash in a proportion of 3:2, Paul gets 60 a larger number than Quinn.

Let 'x' be the share of Paul and 'y' be the share of Quinn. Then the equation is given as,

x: y = 3: 2          ...1

x = y + 60         ...2

From equations 1 and 2, then we have

(y + 60) / y = 3/2

2y + 120 = 3y

y = 120

Then the value of the variable 'x' is given as,

x = 120 + 60

x = 180

The amount of money that Paul and Quinn have will be $180 and $120, respectively.

Answer:

Adults= 110

Children= 340

Step-by-step explanation:

Given data

let adults be x

and children be y

x+y= 450----------1

2x+y=680---------2

from 1

x= 450-y

put this in 2

2(450-y)=680

900-2y=680

900-680=2y

220=2y

y= 220/2

y= 110

x+110= 450

x= 450-110

x=340

Step-by-step explanation:

x = 1/2 Arc AB ( Relation between inscribed angle and corresponding arc)

x = 1/ 2 * 124

x = 62°

y = x ( Inscribed angles on standing on same arc are equal)

y = 62°

Answer:

7x^4-y^3-3

Step-by-step explanation:

Distance from the tip to the middle of the turbine = Radius of the circular turbine

Radius of the circular turbine = 32 meters

Circumference of the circular turbine = distance the turbine will travel in one revolution

We know that :

[tex]\tt \: \color{hotpink}circumference \: of \: a \: circle \color{plum}= 2\pi r[/tex]

Circumference of the circular turbine :

[tex] = \tt2 \times \frac{22}{7} \times 32 [/tex]

[tex] = \tt\frac{2 \times 22}{7} \times 32[/tex]

[tex] =\tt \frac{44}{7} \times 32[/tex]

[tex] =\tt \frac{44 \times 32}{7} [/tex]

[tex] =\tt \frac{1408}{7} [/tex]

[tex]\color{plum} =\tt 201.06 \: m[/tex]

▪︎201.06 m can be roughly rounded off to 200.96.

▪︎Thus, the distance the turbine will cover in one revolution = 200.96 m

▪︎Therefore, the correct option is (A) 200.96

Answer:

x = 2

y = 12

Step-by-step explanation:

In triangle ABD, CE is the mid segment.

Therefore, by mid segment theorem:

2(5x - 3) = x + 12

10x - 6 = x + 12

10x - x = 12 + 6

9x = 18

x = 18/9

x = 2

Since, DE = EA

2y - 4 = y + 8

2y - y = 8 + 4

y = 12

Answer:

Step-by-step explanation:

The answer is 1 2 and 4

The correct options are 1 and 3.

The expression can be written as 4n + 7, involving multiplication and addition.

Given is a verbal expression "Four times a number increased by seven"

We need to convert it into algebraic expression.

So,

Replace "a number" with the variable, n.

This means we replace the phrase "a number" in the expression with the variable "n".

So, the expression becomes "Four times n increased by seven," which can be written as "4n + 7."

The two operations are multiplication and addition.

This option is correct.

The expression involves two operations: multiplication and addition.

We have "Four times a number" which means we multiply the number by 4, and then "increased by seven" means we add 7 to the result.

So, the expression can be written as 4n + 7, where 4n represents the multiplication and +7 represents the addition.

The expression is written as 4n + 7.

This option is correct. The given expression "Four times a number increased by seven" can be written as 4n + 7, where 4n represents the multiplication of the number by 4 and +7 represents the addition of 7 to the result.

So, the correct options are 1 and 3.
