Answer:
150 and 240 are the two numbers having difference as 90 and ratio as 5 : 8.
Step-by-step explanation:
Since ratio of two numbers is 5 : 8 ,
lets assume two numbers be 5x and 8x.
Difference of two numbers = 8x - 5x = 90
⇒3x =90
⇒x = 90/3=30
so two numbers are 5x = 5 × 30 = 150 and 8x = 8 × 30 = 240
Hence 150 and 240 are the two numbers having difference as 90 and ratio as 5 : 8.
Answer:
BI=27%
Step-by-step explanation:
x(the precentage of 55 from 75)
75x=55
x=55/75
x=0.73
55 is 0.73 of 75
0.73*100=73%
100%-73%=27%
Answer: C, It stays the same.
Step-by-step explanation: If you simplify the ratio (the fraction) by canceling the t's, you get 2/1 or 2:1. This means that no matter the value of the variable t, the value of the expression will stay the same.
Answer:
2 ( plot the answer on 2)
Step-by-step explanation:
We do the reciprocal of 3/10 because we are dividing fraction. Which would be 10/3. Change the sign to multiplication because we are dividing fractions. And multiply regularly. SO it would be 3/5 times 10/3 = 2
The correct algebraic expression is X ÷ 5 - 17 = 41
<h3>What is an algebraic expression?</h3>
An algebraic expression is a term that refers to a way of representing mathematical operations in which letters and numbers are combined, related to signs of the operations such as:
- Addition (+)
- Subtraction (-)
- Multiplication (×)
- Division (÷)
- Empowerment ()
According to the above, we can infer that the correct algebraic expression would be:
In this algebraic expression the letter X represents a number that we do not know and we must find.
