Answer:
80%
Step-by-step explanation:
5 times 20 = 100 so with that each 5th is 20% so 4 times 20 is 80

Good luck!
con someone hwlp me please i can give you a brainle
Answer:
For the first section, you write the algebraic expression or equation that goes with the statement.
For example, 9 more than the product of 51 and number "i" would translate into 51i+9. More and sum refers to addition, difference is subtraction, and quotient is division.
For the second section, you just simplify each of the expressions. when a number has ^, that means it has the square root, so 9^2 would be nine squared, which is 81.
For the third section, replace the c values for 3 and the d values for 5.
For the fourth section, determine whether or not each number is rational by writing the number as a fraction where both numerator and denominator are whole numbers. Pi is irrational as it can't be written as the fraction of 2 integers
For the last section, combine like terms and explain each step.

Isabel wants to start saving more money so that she can purchase new clothes for college. She has $200 and will add $5 to her savings every day. Which equation models Isabel’s savings, where n represents each day ?
Answer:
Step-by-step explanation:
n-5=200
Answer: an= 5n +
Step-by-step explanation:
I don’t really know but she has $200 and she wants to add $5 to her savings everyday so it can’t be an= 5an-1 because we’re adding but n means everyday so 5n would represent that so yeeahhhh hope that helped
What is the greatest common factor of 42 and 14?
It is 14 because if you do prime factorization:
14 = 2 x 7
42 = 2 x 3 x 7
They have the factors 2 and 7 in common.
2 x 7 = 14.
Answer:
The GCF is 14!
Step-by-step explanation: Okay Lets multiply to get 42, 14 x 1 is 14, 14 x 2 is 28, 14 x 3 is 42! We also know that this is the GCF because 42 and 14 can both be divided by 14!

Which expression is equivalent to √100 +4√10 +3 −8 √10?
1) −4√10 + 13
2) 10 − √10
3) 3 − 2√10
4) √10
Answer:
√100 +4√10 +3 −8 √10 = −4√10 + 13 TRUE
Step-by-step explanation:
Simplify the following:
sqrt(100) + 4 sqrt(10) + 3 - 8 sqrt(10)
Hint: | Simplify radicals.
sqrt(100) = sqrt(10^2) = 10:
10 + 4 sqrt(10) + 3 - 8 sqrt(10)
Hint: | Evaluate 10 + 4 sqrt(10) + 3 - 8 sqrt(10).
10 + 4 sqrt(10) + 3 - 8 sqrt(10) = 13 - 4 sqrt(10):
Answer: 13 - 4 sqrt(10)

What is the value of x?
93
87 78
72
Answer:
72°
Explanation:
Given that line J and line K are parallel, we can safely assume that line m is the transversal for the following question. We can also remove line l so that we can focus on line m instead.
Using the rule of Alternate Exterior Angle theorem, x would equal to 72°.
Answer: 72
Now that we are told that J and K are parallel, we know that there can be a transversal line (m). You can see that m goes 72 degrees.
So, the answer is 72. Best of Regards!
True or False?
-6 is a solution for -4x > 16
Answer:
True
Step-by-step explanation:
-4x > 16
Divide each side by -4, remembering to flip the inequality since we are dividing by a negative
-4x/-4 < 16/-4
x < -4
-6 is less than -4 so -6 is a solution to the inequality
Answer: True
Step-by-step explanation:
It equals 24>16
Given a triangle JLM with vertices J(-4,3), L(-2,7), and M(2,7). What would the coordinates be if it was reflected across the line y=1?
Answer: M'(2, - 5), L'(-2, -5), j'(-4, - 1)
Step-by-step explanation:
When we do a reflection over a given line, the distance between all the points (measured perpendicularly to the line) does not change.
The line is y = 1.
Notice that a reflection over a line y = a (for any real value a) only changes the value of the variable y.
Let's reflect the points:
J(-4, 3)
The distance between 3 and 1 is:
D = 3 - 1 = 2.
Then the new value of y must also be at a distance 2 of the line y = 1
1 - 2 = 1
The new point is:
j'(-4, - 1)
L(-2, 7)
The distance between 7 and 1 is:
7 - 1 = 6.
The new value of y will be:
1 - 6 = -5
The new point is:
L'(-2, -5)
M(2,7)
Same as above, the new point will be:
M'(2, - 5)

2.) During typhoon ambo PAGASA tracks the amount of the accumulating rain fall. For the first three hour's of typhoon that rain fell at a constant rate of 25 mm per hour. The typhoon slows down for an hour ad started again at a constant rate of 20 mm per hour for the next 2 hour's . Write a piecewise function that models the amount of rain fall as function of time.
(this is for a friend)
Answer:
Step-by-step explanation:
Given that :
First 3 hours, rain fell at a constant rate of 25mmper hour
Next one hour, tmrain slowed down
Next 2 hours, rate of 20mm per hour
Piecewise function which models the situation :
________{25t ; t in range {0, 3)
f(x)______{75 ; t in range {3,4}
________{75 + 20(t-4) ; t in range {4,6}
Hence, the function.
Consider this equation.
7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)
Mia solved the equation and determined that m = 2. Is she correct?
She is incorrect because when substituting 2 for m the result was a true statement.
She is incorrect because when substituting 2 for m the result was a false statement.
She is correct because when substituting 2 for m the result was a true statement.
She is correct because when substituting 2 for m the result was a false statement.
Can someone please help me?
Answer:
it's wrong
Step-by-step explanation:
because the answer in this 7.8 + 2(0.75m+ 0.4) is not 6.4
Answer:
B she is incorrect because when substituting 2 for m the result was a false statement

we know that bc+cd=bd
plug in what we wre given
23+22= bd
add.
for 2:
we know that ef+fg=eg
plug in what we know
