Answer:
C. 3(2x + 5y) is the algebraic expression equivalent to the expression
Step-by-step explanation:
From the question, the given expression is 6x + 15y.
Factorizing this expression gives 3(2x + 5y). Hence, the algebraic expression equivalent to the expression 6x + 15y is 3(2x + 5y). (Option C).
Checking the remaining options
A. 3(2x - 5y)
Expanding this gives 6x - 15y. It is not equivalent to the given expression
B. 3(5x - 2y)
Expanding this gives 15x - 6y. It is not equivalent to the given expression
D. 3(5x + 2y)
Expanding this gives 15x + 3y. It is not equivalent to the given expression.
Hence, C. 3(2x + 5y) is the algebraic expression equivalent to the expression.
Hello,
When you are looking for a ratio, it is simply a fraction.
In the numerator, we will put the amount of the increase which is 10.4 - 7.80 = 2.6.
In the denominator, we will put the original price of $7.80.
This gives us the ration of 2.6/7.8 or just 0.33 if we divide.
We can say there was a 33% increase (or one-third).
I hope this helps, Good luck!

Answer:
D Laura shaded the factors instead of the multipls of 12
Step-by-step explanation:
The factors of 12 are 1, 2, 3, 4, 6, and 12, because each of those divides 12 without leaving a remainder
The multiples of 12 are 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144
Answer:
The answer is x=27/28
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
From 72 to 90 it is a 25% change
