Combine like terms:
-r-10r
We can always add variables as long as they are the same. So we can not add 10x+20y. That's impossible.
We can't add 3r^2+10r. That's also impossible.
However, we have the same variable, r. So we can add -r-10r. And the answer is:
-11r
Hope this helps! :)
Hey there!
-r - 10r
= -1r - 10r
COMBINE the LIKE TERMS
= (-1 - 10r)
= -11r
Therefore, your answer is: -11r
Good luck on your assignment and enjoy your day!

roy gets 10% extra time in school exams. If Roy gets 1 hour 33 minutes and 30 seconds to complete his maths exam, how long do most students get.
Answer:
1 Hour 25 Minutes
The time that most of the students get is 1 hour and 25 minutes, computed using fractions and percentages.
What are fractions?Fractions are a relational representation of certain parts of a quantity, to the total parts of that quantity.
Written as a/b, read as "a by b", functions as a divided by b, represents a fraction a over b, where a is the numerator and b is the denominator.
What are percentages?Percentages are a fractional representation of a quantity, where the whole quantity is fixed to be 100.
Fractions are converted to percentages by multiplying them by 100, while percentages are converted to fractions by dividing them by 100.
How to solve the question?In the question, we are informed that Roy gets 10% extra time in school exams.
We are asked for the time that is given to most of the students if Roy gets 1 hour 33 minutes and 30 seconds.
For standardization, we work in seconds.
We assume the required time to be x seconds.
Time given to Roy:
30 seconds implies 30 seconds,
33 minutes implies 33*60 = 1980 seconds,
1 hour implies 1*60*60 = 3600 seconds.
Thus, the total time given to Roy = 30 + 1980 + 3600 = 5610 seconds.
We are informed that Roy gets 10% extra time in school exams.
Thus, the time given to Roy = Normal time + 10% of normal time,
or, 5610 = x + 10% of x,
or, 5610 = x + 10/100 of x {percentages are converted to fractions by dividing them by 100},
or, 5610 = x + x/10,
or, 5610 = 11x/10,
or, x = 5610*10/11 = 5100.
Thus, the time given to most of the students = 5100 seconds = 5100/60 minutes = 85 minutes = 1 hour and 25 minutes.
Thus, the time that most of the students get is 1 hour and 25 minutes, computed using fractions and percentages.

What criterion statement accurately proves that ∆ABC is congruent to ∆DEF?
A-SSS criterion
B-AAS criterion
C-ASA criterion
D-SAS criterion
Explanation:
The angles marked with a single arc pair up and are congruent (angles ACB and DFE). This forms one "A" of "ASA". The other "A" refers to the angles BAC and EDF as shown by the double arcs.
The "S" refers to the pair of congruent sides between the angles mentioned. Specifically, the diagram shows that AC = FD based on the tickmarks on those segments.

Answer:
Star and square
Step-by-step explanation:
Answer: B
Step-by-step explanation:
The origin is the center of the 2 bold lines. As you can see, the square is 1 unit right and then 2 units up. The star is 2 units left and 1 unit up. And the triangle is 2 units down and 2 units left.
square: 1 then 2
star: 2 then 1
triangle: 2 then 2.
From this you can see that the square and the star are the same distance from the origin.
So the answer is B.

2.5 * 10^14
Step-by-step explanation:
(5 x 10⁶) * (5 x 10⁷)
= (5 * 1000000) * (5*10000000) Step 1
tip : When multiplying tens with exponents, consider adding zeros according to the exponent the 10 is raised to. For example, 10⁶ would be 1000000 (six zeros)
= (5000000) * (50000000) Step 2
= 250000000000000. Step 3
= 2.5 * 10^14 Step 4 move your decimal point to the left (14 times) until you you condense your value into a smaller decimal (2.5)

The simplest form of 6⁵ x 6² is 6⁷
Exponents:The way of representing huge numbers in terms of powers is known as an exponent. The exponent of a number is the number of times a number has been multiplied by itself.
For example, 3 is multiplied by 4 times itself, i.e. 3 × 3 × 3 × 3. This can be represented as 3⁴. Where 3 is the base and 4 is the exponent.
The following are the some of formulas in exponents
=> aᵇ. aˣ = aᵇ⁺ˣ=> (ab)ˣ = aˣ bˣ=> (a/b)ˣ = aˣ/bˣHere we have
The expression 6⁵ x 6²
We can simplify the given equation by using exponent formulas
As we know, aᵇ × aˣ = aᵇ⁺ˣ
=> 6⁵ x 6² = 6⁵⁺² = 6⁷
