explain why 2a+3b=5ab
Answers
That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.
If you had 2a+3a, then it would simplify to 5a
Similarly, 2b+3b = 5b
Or you could have 2ab+3ab = 5ab
The key is that the variable portions must match up to be able to add them.

The ratio of boys to girls in a class is 5:7. There are 36 students in the
class. How many students are boys?
Answers
Answer:
15
Step-by-step explanation:
The ratio has been simplified so it may be hard to read.
To fix this multiply both the 5 and 7 by 3
This will give you 15:21
15 + 21 = 36 which is the total number of students.
Keeping the ratio in the same order means that there are 15 boys.
Answer:
There are 15 boys in the class.
Step-by-step explanation:
There are several ways to solve this, but here's how I did it:
5 (boys) : 7 (girls) = 12 students. There are 26 students, so we need to multiply this by 3.
15 (boys) : 21 (girls) = 36 students.

x = 770 people
5. 15 laps = 30 laps
8 x
just cross multiply:
15x = 30(8)
x = 240 / 15
x = 16 mins
6. 18 laps = x
10 6

3[-x + (2 x + 1)] = X – 1
Answers
Your question has been heard loud and clear.
3[-x + (2 x + 1)] = X – 1
= 3[-x+2x+1]= x-1
= 3 [ x+1] = x-1
= 3x+ 3 = x-1
3x-x = -3-1
2x= -4
so , x = -4/2 = -2
Therefore , x = -2

owenn goes on a camping trip with his family cabin rentals are $430 for the week, kayak rentals are $7 per hour and paddle boards are $9 an hour, write an algebric expression to represent how much the family will spend if they stay for one week and plan on renting both kayaks and paddle boards while on their tripoi
Answers
Answer:
430 + 16h
Step-by-step explanation:
They are staying for a week ($430)
They are renting both a kayak ($7 per hour) and paddle board ($9 per hour), without defining the amount of hours. Create a variable, for example H for hours.
To create the expression, take the $430, the $7 per hour and $9 per hour, or 430 + 16h.

Owen's model is represented by -
3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that Owen creates this model to determine the product of two decimals.
The equation that represents the Owen's model is -
3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44
Therefore, Owen's model is represented by -
3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44

y = 3 is written in slope-intercept form (y = mx + b).

We don't have a slope variable at all which means the slope is 0 or undefined.
The y-intercept is 3.
