Actually Welcome to the Concept of the Simple maths.

Here,

61 = r/3 - 7

hence, r/3 = 61+7

===> r/3 = 68

==> r = 68*3

====> r = 204

Option c.) is correct.

Answer: -8x

Step-by-step explanation:

Answer: x(-8)

Step-by-step explanation:

product= multiplication

a number could be any variable you want

negative 8 is -8

so the product of a number x(   ) and negative 8 is x(-8)

Answer:

  y = -3/2x +11

Step-by-step explanation:

The slope of the parallel line is the same as the slope of the given line, so ...

  m = -3/2

The y-intercept of the parallel line can be found from ...

  b = y -mx

  b = 5 -(-3/2)(4) = 11

So, the desired equation is ...

  y = mx +b

  y = -3/2x + 11

_____

Additional comment

Since you know the slope and a point on the desired line, you can write down the equation directly using the point-slope form. No additional math is required.

  y -5 = -3/2(x -4)

Answer:

D

Step-by-step explanation:

It means that the square MNOP is 3.5 times bigger than square ABCD

side MNOP = 3.5 x 15 = 52.5

Answer:

x = 3z(y - 2)

Step-by-step explanation:

Given

[tex]\frac{x}{3z}[/tex] = y - 2 ( multiply both sides by 3z to clear the fraction )

x = 3z(y - 2)

Answer:

The answer is A it's an isosceles

Answer:

6

Step-by-step explanation:

All you have to do is subtract the smallest number from the biggest number. In this case, that would be 7-1 which is equal to 6. Therefore, the range of the data set is 6.

Answer: 15 hours

Step-by-step explanation: X = 1 hour add up all the x's there's 15 x's witch means 15 hours.

Answer: 2 1/2kg

Step-by-step explanation:

Weight of plant food bought = 4 1/2kg

Amount used on strawberry plant = 1 2/3kg

Amount used on tomato plant = 1/4kg

Therefore, the amount used will be:

= 1 2/3 + 1/4

= 1 8/12 + 3/12

= 1 11/12kg

We then subtract the value gotten from the amount bought. This will be:

= 4 1/2 - 1 11/12

= 4 6/12 - 1 11/12

= 2 6/12

= 2 1/2kg

Answer:

D.

Step-by-step explanation:

To see if a line is parallel to y = -(2/3)x + 8 you need to check if the coefficients at y and x are of the same ratio. This immediately removes answers A and C, because of the wrong sign at x compared to y.

What's left is to see which of the answers B and D passes through (4, -5) by inputting x = 4 and y = -5

B.

left = -5 - 5 = -10

right = -(2/3)(4 + 4) = -16/3

So it's D. Let's verify:

D.

left = -5 + 5 = 0

right = -(2/3)(4 - 4) = 0

Checks out.

Answer:

Option D

Step-by-step explanation:

→ Find the gradient of the parallel line

[tex]y=-\frac{2}{3} x+c[/tex]

→ Substitute in the coordinates as x and y values to find c

[tex]5=-\frac{2}{3} *-4+c[/tex]

→ Simplify

[tex]5=\frac{8}{3} +c[/tex]

→ Minus  [tex]\frac{8}{3}[/tex]  from both sides to find c

[tex]c = \frac{7}{3}[/tex]

→ Expand out all options and then see which one contains all the numbers above

Option D

Answer:

108

Step-by-step explanation:

27 ÷ 3 = 9

2 x 6 = 12

so then you do 9 x 12

which is 108

Answer:

15.3 m/s

Step-by-step explanation:1) Find the gravitational potential energy using the equation :

     [tex]PE_g=mgh[/tex]

    [tex]PE_g=2.5(12)(9.8)\\PE_g=294[/tex]

2) Then use the equation for kinetic energy to solve for the velocity:

     [tex]KE=\frac{1}{2} mv^{2}[/tex]

     [tex]294=\frac{1}{2}(2.5)(v^2)\\235.2=v^2\\\sqrt{235.2} =v\\15.3 m/s=v[/tex]

Answer:

32 Square centimeters

Step-by-step explanation:

You have to seperate the shape into triangles and rectangles. if you do this, you get 2 identical triangles and 2 different rectangles. one of the rectangles is 8 square cm, the other is 12. you can see that the base of each of the 2 triangles is 3 cm long. 2 halves=1 whole, so the 2 triangles turn into 1 rectangle. therefore, you have to add 12+12+8. That is 32 square centimeters.

Answer:

A = 16π cm²

Step-by-step explanation:

We require to find the radius r

Given circumference C = 8π , then

2πr = 8π ( divide both sides by 2π )

r = 4 , then

A = πr² = π × 4² = 16π cm²

Answer:

A = 16π cm²

Answer:

21x² + 22x - 8

Step-by-step explanation:

(3x+4)(7x-2)​ = 21x² - 6x + 28x - 8 = 21x² + 22x - 8

Answer:

B.

Step-by-step explanation:

Let's use the FOIL (First, Outside, Inner, Last) method.

We need to multiply the first terms in each pair of parentheses, which are

3x and 7x.

Multiplying, we get [tex]21x^2[/tex].

We multiply the outside terms in each pair, which are 3x and -2.

Multiplying, we get [tex]-6x[/tex]. Remember that since -2 is negative, then the whole product is negative.

We need to multiply the inner terms now. They are 4 and 7x.

Multiplying, we get [tex]28x[/tex].

Finally, we multiply the last terms in each pair of parentheses. they are 4 and -2.

Multiplying, we get [tex]-8[/tex].

Now, we put the terms together.

[tex]21x^2-6x+28x-8[/tex]

We can combine -6x, and 28x. Doing this, we get

[tex]21x^2+22x-8[/tex]. Which gives us B.

I hope this helped.

Answer:

Step-by-step explanation:Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola.

The vertex of a parabola is the point at the top or bottom of the parabola.

'h' is -6, the first coordinate in the vertex.

'k' is -4, the second coordinate in the vertex.

'x' is -2, the first coordinate in the other point.
