Answer:

The two numbers are 18 and 42

Step-by-step explanation:

let the two numbers = x  and y

Their sum:    x + y = 60 ------ (1)

Also, dividing the larger by the smaller (partition = 2 and remainder = 6).

Let the larger number = y

\frac{y}{x} = 2\frac{6}{x} \\\\\frac{y}{x} = \frac{2x +6}{x} \\\\y = 2x + 6\ \ ----(2)

Substitute the value of y into equation (1)

x + (2x + 6) = 60

x + 2x + 6 = 60

3x  +  6 = 60

3x = 60  - 6

3x = 54

x = 54 / 3

x = 18

y = 2x + 6

y = 2(18) + 6

y = 36 + 6

y = 42

The two numbers are 18 and 42

Can someone please help with this maths !!!!!
ioda

Answer:

C)  -3

Step-by-step explanation:

Rearrange your equation so that it is in slope-intercept form (y = mx + b).  The m in the equation is the gradient.

y = 7 - 3x

y = -3x + 7

The m-value is -3.  This means that the gradient is -3.

What is the width of a rectangle with a length of 14 cm and an area of 161 cm squared
mestny [16]
Area of a rectangle=length×width. If the area is 161 and the length is 14 then that means: 161=14×width. You would then divide 161÷14 and you will find that the width is 11.5.
