Two numbers have these properties:

Mathematics

almond37 [142]3 years ago
5 0

Answer:

12\ and\ 30

Step-by-step explanation:

Given both numbers are greater than 6

Their HCF is 6

Their LCM is 60

The product of the HCF and LCM of two numbers is the same as the product of the numbers themselves.

Let us say those number are a and b

a\times b=6\times 60\\a\times b=360

So, the product of those number is 360

Let us factorize 360

360=1\times 2\times 2\times 3\times 5\times 6

It is given that number should be greater than 6

The possible pairs of number are (10,36)\ and\ (12,30)

But only (12,30) has LCM as 60.

So those numbers are 12\ and\ 30

-2(8+8x)+7x=-7x+2(x-8)
Inessa [10]

x=0 .

−2(8+8x)+7x=−7x+2(x−8)

Step 1: Simplify both sides of the equation.

−2(8+8x)+7x=−7x+2(x−8)

(−2)(8)+(−2)(8x)+7x=−7x+(2)(x)+(2)(−8)(Distribute)

−16+−16x+7x=−7x+2x+−16

(−16x+7x)+(−16)=(−7x+2x)+(−16)(Combine Like Terms)

−9x+−16=−5x+−16

−9x−16=−5x−16

Step 2: Add 5x to both sides.

−9x−16+5x=−5x−16+5x

−4x−16=−16

Step 3: Add 16 to both sides.

−4x−16+16=−16+16

−4x=0

Step 4: Divide both sides by -4.

−4x /−4 = 0 /−4

x=0

What is the area of rectangle ABCD given the information below?
SashulF [63]

Answer: Area is 1840units²

Step-by-step explanation:

From the given information,

Firstly, area of a rectangle is given as

A = l × b ie, length multiply by the breadth.

One of the side of the rectangle is known , AD = 16 , now to calculate the other side, we need some calculations.Since FE = 23 and

FD = DE ,,therefore,

DE = 23/2.

From the information, DE = 1/10 of DC. We now find DC the required side for finding the area of the rectangle by simple equation. Since DE = 23/2 , the equation now looks like this to get DC

23/2 = DC/10. Now , solving this

2DC = 23 × 10

2DC = 230

DC = 230/2

= 115.

Now the area of the rectangle will be

A = 16 × 115

= 1840units²
