The LCM of two numbers is 60. Their GCf is 6 and their difference is 18. What are the two numbers?
Aliun [14]
LCM(x,y)=60\\
GCF(x,y)=6\\
x-y=18\\\\
LCM(x,y)=\dfrac{|x\cdot y|}{GCD(x,y)}\\
60=\dfrac{|x\cdot y|}{6}\\
|x\cdot y|=360\\\\\\
|x\cdot y|=360\\
x-y=18\\\\
|x\cdot y|=360\\
x=18+y\\\\
|(18+y)\cdot y|=360\\
|18y+y^2|=360\\
18y+y^2=360 \vee 18y+y^2=-360\\
y^2+18y+81=441 \vee y^2+18y+81=-279\\
(y+9)^2=441 \vee (y+9)^2=-279\\
y+9=\sqrt{441} \vee y+9=-\sqrt{441}\\
y=21-9 \vee y=-21-9\\
y=12 \vee y=-30\\\\
x-12=18 \vee x-(-30)=18\\
x=30 \vee x=-12\\\\
\boxed{x=30, y=12 \vee x=-12, y=-30}

you will follow BODMAS

B=bracket

O= off

D=division

M=multiplication

A=addition

S=subtraction

2×3=6

7×2=14

[6-14±10x-8]÷[x-2]

14±8=22

6-22=-16

[-16±10x]÷[x-2]=-8±10x

1: 2 2/3 - 3/5 <br> 2: 2 1/5 + 1 1/10<br> 3: 2 5/7 - 2/3<br> 4: 1/4 + w = 6 1/3
Yanka [14]

2 2/3 - 3/5 = 2 1/15

2 1/5 + 11/10 = 3 3/10

2 5/7 - 2/3 = 2 1/21

1/4 + w = 6 1/3

w = 6 1/12

Hope this helps :)

Translate the following into an algebraic expression: The number that is 40% more than five more than a number a.
cricket20 [7]

Answer:

The translation would be

X = 40% + 5 + A

Step-by-step explanation:

First, translate the words, is, more than and 'the number'.

Is means equals (=).

More Than means plus (+).

'the number' can be x.

Now, put it together.

X(The Number) =(Is) 40% +(more than) 5 +(more than) A(a number)

I hope this helps!!
