Answer: 25 chocolate frogs eaten by Luna

Step-by-step explanation:

let the amount of chocolate frogs eaten by Luna = x

and the amount of chocolate frogs eaten by Harry = 6+ x

Such that total a,mount of chocolate frogs eaten by both of them

= x +( 6+x) = 56

Step 2- Solving

x+6+x=56

6 + 2x= 56

2x= 56-6

2x= 50

x= 50/2

x= 25

x= 25 chocolate frogs eaten by Luna

6 +x= 6+ 25= 31 chocolate frogs eaten by Harry.

Answer:

a) 18

not sure about b sorry I'm literally doing it now in maths lol

Answer:

56 degrees

Step-by-step explanation:

a straight angle is 180 degrees so you subtract 180 and  124 and get 56

Answer: 56 degrees

Step-by-step explanation:

Line AD is supplementary, therefore subtracting 180 from 124 is 56 degrees.

Step-by-step explanation:

Answer:

They are all equal sides so divide 180 by 3

Step-by-step explanation:

Answer:

yes,  point (4, 25) satisfies the equation y = 7x + –3

Step-by-step explanation:

to see if the point satisfies the equation, we need to plug in the x coordinate to get y

if y is equal to the y-coordinate, then the point satisfies the equation

if y does not equal the y-coordinate, then the point does not satisfy the equation:

y = 7(4) + - 3

y = 28 + -3

y = 25

does 25 = 25? Yes! so the point satisfied the equation

Answer:

yes

Step-by-step explanation:

7(x)- 3 = y

7(4) - 3 = (y)

28 - 3 = 25

Answer:

x ≈ 2.76

Step-by-step explanation:

The inscribed angle (34x + 4) is half the measure of its intercepted arc, then

34x + 4 = [tex]\frac{1}{2}[/tex] × 196° = 98 ( subtract 4 from both sides )

34x = 94 ( divide both sides by 34 )

x ≈ 2.76 ( to the nearest hundredth )

Answer:

Pythagoras's theorem

Step-by-step explanation:

In the given drawing, there are three right triangles (two smaller triangles formed inside one right triangle), which are;

1) The smallest right triangle with side lengths 'b', 'f', and 'd'

2) The intermediate right triangle with side lengths 'f', 'a' and 'c - d'

3) The right triangle ΔABC containing the other two with side lengths, 'a', 'b', 'c'

By trigonometric ratio we have;

1/cos(B) = a/(c - d) = c/a

By cross multiplication, we get

a² = c² - c·d

Similarly, we have;

The vertex angle for the small right triangle at C = ∠B

1/sin(B) = b/d = c/b

∴ b² = c·d

Therefore, adding the values of 'a²', and 'b²' together, we get;

a² + b² = c² - c·d + c·d = c²

Therefore;

a² + b² = c² which is Pythagoras's theorem.

Answer:

6n-14

Step-by-step explanation:

First, put 6 times a number down, which is 6n, then minus 14, so it would be 6n-14.

The numerical form of statement 4 is less than 6 times a number, and n is

6n - 4.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

The given statement is 4 less than 6 times a number, n.

Therefore, The statement can be numerically expressed as,

6×n - 4.

= 6n - 4.

If 6n - 4 is an expression then 6n - 4 = 0  is an equation.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.
