Answers

Answer 1

Answer:

x=39

Step-by-step explanation:

It is a four sided thing so the sum of all angles is 360

hence

2x + 3x - 15 + 2x + 2x + 24 = 360

and

x will be 39

Answer 2
3x - 15 = 2x + 24
x - 15 = 24
x = 39

(2x + 24) + 2x = 180
4x + 24 = 180
4x = 156
x = 39

2x + (3x - 15) = 180
5x - 15 = 180
5x = 195
x = 39

The number of boys and girls in a class are in the ratio 4 : 7. There are 15 more girls than boys. find the number of total students in the class

Answers

Answer:

The number of total students in the class is 55

Step-by-step explanation:

We will use the ratio method to solve the question

∵ The number of boys and girls in a class are in the ratio 4: 7

∵ There are 15 more girls than boys

→ That means the difference between them is 15

∵ The difference between the terms of their ratio = 7 - 4 = 3

→ By using the ratio method

→  boy  :  girl  :  difference

→  4      :  7      :  3

→  x      :  y      :  15

→ By using cross multiplication

∵ x × 3 = 4 × 15

∴ 3x = 60

→ Divide both sides by 3

∴ x = 20

∵ y × 3 = 7 × 15

∴ 3y = 105

→ Divide both sides by 3

∴ y = 35

∵ x represents the number of boys

∴ The number of boys is 20

∵ y represents the number of girls

∴ The number of girls is 35

∴ The total number of students = 20 + 35 = 55

∴ The number of total students in the class is 55

Which choice is the equation of the line that passes through the point (5, 19) and has a slope of
m=12 and is written in slope–intercept form?

Answers

Answer:

The equation is;

y = 12x-41

Step-by-step explanation:

Mathematically;

slope intercept form is;

y = mx + b

where m is slope and b is intercept

Since we already have the slope , the equation is;

y = 12x + b

To get b which is the y intercept, we simply substitute the value of the points given

Thus;

19 = 5(12) + b

19 = 60+ b

b = 19-60

b = -41

So the equation is;

y = 12x - 41

Circumference of circle 1 : Circumference of circle 2 = 1 : 2

Step-by-step explanation:

Circumference of a circle = πD, where D is the diameter.

Diameter of circle 1 = 1.125

Circumference of circle 1 = π x 1.125

Diameter of circle 1 = 2.25

Circumference of circle 1 = π x 2.25

Circumference of circle 1 : Circumference of circle 2 = 1 : 2

Step-by-step explanation:

A prime number is a result of two other whole numbers multiplied by themselves. There is no whole number that you can multipy by itself to get 2 because 1 × 1 = 1 and 2 × 2 = 4. Therefore, it is a prime number. But, that does not mean it is an odd number because odd numbers are 1, 3, 5, 7, etc. and even numbers are 2, 4, 6, 8, etc.
