Answer:
The unknown number is 90
Step-by-step explanation:
This question requires a good understanding so as to interprets it well
And always ensure that all symbols used in representation are well stated so as to help the examiner or anyone who will mark it to understand better
So back to the question,let the unknown number be x
And two thirds of the unknown number is 2/3x
2/3x was decreased by 20 which can be written as 2/3x-20
And this decrease gives 40
That's,2/3x-20=40
Then go ahead to solve the question
Start by finding the LCM and the LCM is 3
2x-60/3=40
Cross multiply
2x-60=40×3
2x-60=120
Collect like terms by adding 60 to both sides
2x=180
Divide both sides by 2
x=90
Therefore the final answer is 90
Answer:
75 yards will be represented by 3
100 yards will be represented by 4
Step-by-step explanation:
Given data:
Length = 100 yards
Width = 75 yards
Scale 1:25
Finding the value that represents 100 yards, simple proportion is used
1 : 25
x : 100
1/x = 25/100
1/x = 1/4
(1/x) *4 = (1/4)*4
(4/x) * x = 1 * x
4 = x
100 yards is represented by 4
Finding the value that represents 75 yards, simple proportion is used
1 : 25
x : 75
1/x = 25/75
1/x = 1/3
(1/x) * x = (1/3) *x
1 * 3= (x/3) *3
3 = x
75 yards is represented by 3
Answer:
-33rs
Step-by-step explanation:
First, distribute in the first part of the equation.
3r(4r-5s)=12r-15rs
Now, distribute in the first part of the equation.
2r(-6r-9s)=-12r-18rs
Combine this together.
12r-15sr-12r-18rs
Combine like terms. (12r and -12r will cancel out to 0.)
-33rs
Hope this helps! Have a wonderful day ^^
