-3/2 is the factor would multiply the second equation to eliminate y.
The correct option is (C).
<h3>What is factor?</h3>
A number or algebraic expression that divides another number or expression evenly—i.e., with no remainder.
Given equation is :
9x+3/4 y =6
2x+1/2 y =9
If we have to eliminate the y variable so we have to multiply it by factor -3/2
Then the second equation become
-3/2(2x+1/2 y =9)
-3x- 3/4 y =- 27/2
As we can see the y variable of both the equation is same.
Hence, -3/2 is the factor would multiply the second equation to eliminate y.

#SPJ1
10 pounds of sugar for 5 litres of cream.
Answer:
x=3 and x=-1.25
Step-by-step explanation:
4x^2-7x=15
subtract 15 from each side:
4x^2-7x-15=0
factor (trying different numbers that the sum is 7 and the quotient is 15)
(2x-6 )(2x+2.5 )=0
2x-6=0 add 6 to each side
2x=6
x=3
2x+2.5=0 subtract 2.5 from each side
2x=-2.5
x=-1.25
Answer:

Which is ordered in ascending order
To do this, it is best to convert the fractions to decimal and then make comparison.
From the options, only (b) is ordered in ascending order and the proof is as follows.

Convert to decimals

By comparison:

Hence, (b) is ordered from least to greatest
The complete factor of the polynomial 36x² - 25 is (6x + 5)(6x − 5). Then the correct option is D.
<h3>What is polynomial?</h3>
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
Factor completely 36x² - 25.
We know that

(6x)² − 5²
(6x + 5)(6x − 5)
The complete factor of the polynomial 36x² - 25 is (6x + 5)(6x − 5). Then the correct option is D.
