are the linear expressions equivalent?
2x-3(1.3x-2.5)=5.9x+7.5
3-2(-2.6x+2.1)=5.2x-1.1
d
Answers
Answer:
not equivalent expressions
Step-by-step explanation:
Expand and simplify both expressions
2x - 3(1.3x - 2.5) - 5.9x + 7.5 ← distribute parenthesis
= 2x - 3.9x + 7.5 - 5.9x + 7.5 ← collect like terms
= - 7.8x + 15
----------------------------------------
3 - 2(- 2.6x + 2.1) - 5.2x - 1.1 ← distribute parenthesis
= 3 + 5.2x - 4.2 - 5.2x - 1.1 ← collect like terms
= - 2.3
Then the 2 expressions are not equivalent
Answer:
2x-3(1.3x-2.5)=5.9x+7.5
Equivalent Expression3-2(-2.6x+2.1)=5.2x-1.1
Not Equivalent ExpressionStep-by-step explanation:
Solving the first linear expression
2x-3(1.3x-2.5)=5.9x+7.52x-3.9x+7.5=5.9x+7.52x-3.9x-5.9x = 7.5-7.5-7.8x = 0x = 0/-7.8x = 0Thus, we can say that it's an equivalent expression.
Now Solving the second linear expression
3-2(-2.6x+2.1)=5.2x-1.13+5.2x-4.2= 5.2x-1.15.2x-5.2x = -1.1-3+4.20 ≠ 0.1Thus, we can say that it's not an equivalent expression.

find the slope of the line passing through the points (9,-9) and (1,-1)
Answers
Answer:
The slope is -1
Step-by-step explanation:
Slope formula:
In (9,-9): 9 is x1 and -9 is y1
In (1,-1): 1 is x2 and -1 is y2
m= y2-y1/x2-x2
m= -1+9/1-9
Which is 8/-8
Simplify:
-1
The slope is -1
Hope this helps!
Answer:
-1
Step-by-step explanation:
To find slope, take the two points and find the RISE/RUN, which is y-y/x-x. Stay consistent with how you order the numbers. In this case, I'll do -1 -(-9) / 1 - 9. That will give you 8/-8, which when simplified gives you -1.

the length and breadth of a piece of land are 20meters and 15 meters respectively. What is the perimeter of this land?
Answers
Answer:
20x15=300
When you need to calculate the Length and Width of a piece of land or anything else, all you need to do is multiply the two numbers.
Step-by-step explanation:
When you have 20 units of land in as the length and 15 units of land as width, then you should multiply.
2x4=?
When you do 2x4, you have to do 2+2+2+2=
but, here, you have a piece of land to calculate, so basically, you have to multiply still. In that way, you will be able to get what 20 and 15's product is.
I'm sorry, sometimes I just can't explain that well, but just remember, in these types of problems, just multiply, that is your answer.
Thank You! I hope I made your day just a little better!

The ratio of students who wear glasses to the total class is 2:5
a. What is the ratio of student who wear glasses to those who don't in simplest form?
b. If there are 15 students who don't wear glasses, how many students are in the class?
students
c. If 5 of the students who didn't wear glasses now do, what is the ratio of students who wear glasses
to those who don't in simplest form?
Answers
Answer:
a. 2:3, b. 25 students, c. 3:2
Step-by-step explanation:
a. 5 (total) - 2 (with glasses) = 3 (without glasses), making the ratio 2:3.
b. We can assign the total students with the variable x. 3:5=15:x, 75=3x, x=25. 25 total students.
c. 25 (total students) - 15 (without glasses) = 10 (with glasses). (10+5):(15-5) is 15:10, which, when simplified, equals to 3:2.
