Answer:
No. 5x and 5x² are not like terms.
When a variable is raised to two different powers, they can not be added together.
Another way to look at it is to note that:
5x + 5x² ≡ 5x(1 + x)
It is more obvious there that 1 and x are not like terms, thus neither are 5x and 5x², though they do have common factors.
Daniel found 9 cents in his backpack, 89 cents in the couch, and 2 dollars and 5 cents in the drawer. What was the total amount of money Daniel found?
Answer:
303 cents.
Step-by-step explanation:
Daniel found 9 cents in his backpack, 89 cents in the couch, and 2 dollars and 5 cents in the drawer
We know that, dollar is equal to 100 cents
2 dollars = 200 cents
It means, Daniel found 9 cents in his backpack, 89 cents in the couch, and 200 cents and 5 cents in the drawer.
Price = 9+89+200+5
= 303 cents
Hence, Daniel found 303 cents.

Please help me :(
A) -2x+12
B)-2x+2
C)-2x-2
D)-2x-8
Answer:
-2x+5
Step-by-step explanation:
Bro the answer are wrong there should on more options of -2x+5
These is explainetation
-1/3 × 6x + -1/3 × 15 ( because -1/3 is multipled to whole bracket)
-2x + 5

Hey! I need some help with this question I'm not very good with math so if anyone would be willing to help me out id be grateful thx.
An asteroid is 10^{8} miles away from earth, and it is traveling at a speed of 10^{5} miles per day.
How many days will it take the comet to reach earth?
Answer:
It will take 10^3 days for the comet to reach earth.
Step-by-step explanation:
10^8 = 100,000,000
10^5 = 100,000
100,000,000/100,000 = 1,000
1,000 is equal to 10^3
Evaluate the expression 43+ (7 - 3) x 2.
Answer:
51
Step-by-step explanation:
Answer: 51
Step-by-step explanation:
Use PEMDAS. First solve inside the parentheses. You will get 43 + (4) x 2. Then, do the multiplication (4x2). You will have 43+8. And that can be simplified to 51. Hope this helps!

8,-1,-5,2? Which one!.............
Answer: I would say -8,-1
Step-by-step explanation:
x = –8, y = 7, and z = –11. x - (-z)
Answer:
[tex]x - ( - z) = x + z =( - 8)+(- 11) \\ = \boxed{ - 19}[/tex]
-19 is the right answer.given mtw=bgk find the values of x and y
Answer:
x = 12
y = 8
Step-by-step explanation:
to solve for x you would set up your equation:
4x - 3 = 45
then solve using algebra:
4x - 3 = 45
4x = 48
x = 12
to solve for y set up your equation as:
11y + 6 = 94
TO GET 94: you will need to subtract 41 and 45 from 180 to get 94.
(each triangle equals 180 and we need the 3rd measure)
solve the equation:
11y + 6 = 94
11y = 88
y = 8
Hope this helped!!
Allison lives 380 miles from her grandmother. She plans to drive to her grandmother's house for the weekend. She will drive an average of 60 miles per hour. Which equation represents the distance (d) Allison has left to drive after h hours?
A. D=380+60h
B. D=(380-60)h
C. D=380-60h
D. D=380h-60
Answer:
its b
Step-by-step explanation:
The equation that represents the distance (d) Allison has left to drive after h hours is given by: Option C: d = 380 - 60h
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
We're given that:
Allison lives 380 miles from her grandmotherShe will drive an average of 60 miles per hour. Distance that Allison has left to drive represented by 'd' (in miles) after h hours.In 1 hour, she averagely covers 60 miles.
In h hours, she averagely covers [tex]60 \times h[/tex] hours
d = distance remaining for her to reach to her grandmother's home after h hours of driving
d = Total distance - distance traveled in h hours
d = 380 - 60×h
(sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together, so 60×h can be simply written 60h)
Thus, the equation that represents the distance (d) Allison has left to drive after h hours is given by: Option C: d = 380 - 60h

find the value of x..
Answer:
B x = 7
Step-by-step explanation:
You know based on the ratio that it's being scaled by 4 times because the one side 4 is 16 in the bigger pentagon.
So if you go the side that matches the one you need to solve, it's 2.5.
2.5 times 4 = 10 so that bigger pentagon side should equal 10.

Find all real numbers z for which the equation (z-5)x^2-zx+5=0 only has one real solution. If you find more than one, then list the values separated by commas.
Step-by-step explanation:
For the quadratic equation to have 1 repeated real solution, the discriminant b² - 4ac must be zero.
=> (-z)² - 4(z - 5)(5) = 0
=> z² - 20(z - 5) = 0
=> z² - 20z + 100 = 0
=> (z - 10)² = 0
Therefore z = 10.
