Can someone tell me the answer to this and explain how to do it?
answer:
-2x + 9 or -2 which is what the question asks
step-by-step explanation:
we have to combine like terms which means terms that are similarin this, only 5x and -7x are like terms since both have x with them9 will stay the same since it does not have a like term5x + 9 + (-7x) = __x + 9
-2x + 9
therefore, -2 goes in the blankA dress is marked up from 75 dollars to 125 dollars. What is the percent increase?

Solve 5x-3y =1,
3x-y=5.
Answer:
Below in bold.
Step-by-step explanation:
5x - 3y = 1
3x- y = 5 Multiply this equation by -3:
-9x + 3y = -15 Now add this equation to the first equation:
-4x = -14
x = -14/-4 = 3.5.
Now substitute for x in equation 1:
5(3.5) - 3y = 1
-3y = 1 - 17.5
-3y = -16.5
y = 5.5.
If g(x)=1-3/4x find the values of g(0), and -5·g(4)-1
If h(x)=|1-7x| find the values of h(1), and 23-h(9)
If f(x)=8-5x find the values of f(4c), and f(4p+3)
Step-by-step explanation:
g(0)= 1
g(5)= 1-3/20 = 17/20
-5.g(4)-1 =-5. (13/16) -1 = -65/16 -1= (-65-16)/16= -81/16
find the value of the following using logarithm tables
(0.3452×98.56)÷(0.06541×451)
Find the value of each number in a logarithm table:
log 0.3452 = -0.4619
log98.56 = 1.9937
log0.06541 = -1.1844
log451 = 2.6542
Add the top two together, then the bottom two:
Top two: -0.4619 + 1.9937 = 1.5318
Bottom two: -1.1844 + 2.6542 = 1.4698
Now subtract the sum of the bottom from the sum of the top:
1.5318 - 1.4698 = 0.062
Now find the antilog:
10^(0.062)
Answer = 1.1535
what is the theoretical probability of a coin toss results in one head and one tail showing?
Answer:
However, the likelihood of getting one head and one tail (in any order) is 2 in 4 (. 5). Note: the probability of a coin flip does not depend on what has happened in previous flips; this is very important !!

Above are two different models of the same triangle. If the area of the model on the left is 20 sq cm, what is the area of the model on the right?
Answer:
The area of the model on the right is 80 sq cm
Step-by-step explanation:
Since the scale for the model on the left is 1 cm = 5 ft, and the scale for the model on the right is 1 cm = 2.5 ft, the area of the model on the right is 22, or 4, times larger than the area of the model on the left.
Multiply the area of the model on the left by 4 to find the area of the model on the right.
20 sq cm × 4 = 80 sq cm

Answer: The answer is C) J' (3,-1), K' (1,-4)
Step-by-step explanation: First, you need to find the location of J, which is located in Quadrant III. You go left 3, and go down 1, making the coordinates of J (-3,-1). Next, you need to find the location of K, which is also located in (-1, -4).
So, the question asks, "What are the coordinates of J' and K' after JK is reflected across the y-axis?"-- Well, first, which line is the x-axis, and which line is the y-axis?
The x-axis is the line that is horizontal(Across) while the y-axis is the line that is vertical( Up and Down).
So you bring J and Ks coordinated over the y-axis to Quadrant IV(4). You already know their original coordinates, so you place the as you would in the picture above, except that the line would be reflected.

Eli claims that the product of 6 Superscript 5 and 5 Superscript negative 3 is 6 squared. Which explains whether Eli is correct?
Eli is correct. He added 5 + (negative 3) to find the exponent of 2.
Eli is incorrect. He added the exponents instead of subtracting them.
Eli is incorrect. He subtracted the exponents instead of adding them.
Eli is incorrect. He added the exponents even though the bases are not the same.
Answer:
d
Step-by-step explanation:
Eli is incorrect because he added the exponents even though the bases are not the same.
Option D is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
[tex]6^5[/tex] x [tex]5^{-3}[/tex] = 6²
Now,
Simplifying the expression.
= [tex]6^5 \times 5^{-3}[/tex]
= [tex]\frac{6^5}{5^3}[/tex]
We see that,
6² is when we add the exponents even if the base is not the same.
We can not add the exponent if the base is not the same.
Thus,
Eli is incorrect because he added the exponents even though the bases are not the same.

Answer:
x + 37 = 90
Step-by-step explanation:
Since complementary angles add up to 90 degrees, we would need to add 37 and x to equal 90 degrees. Therefore, x + 37 equals 90 degrees. As for solving, subtract 37 from both sides and you are left with x = 53.

A right triangle with vertices labeled as A, B, and C. Side C B is the base, and the top vertex is A. Side A B contains a midpoint D. A line segment drawn from C to D bisects angle A C B into two parts labeled as A C D and B C D. Angles A C D and B C D are marked with single arc. Side A C is labeled as 3. Base C B is labeled as 4. Segment A D is labeled as 2.25. Segment B D is labeled x.
Use triangle bisect or theorem.
Set up proportion:
X/ 2.25 = 4/3
Cross multiply:
3x = (4 x 2.25)
3x = 9
Divide both sides by 3:
X = 3
HELP When does expanding and simplifying a(b + c) result in a positive value for ac?
Answer:
When c and a are positive or both are negative
Step-by-step explanation:
negative times negative equals positive so if a was negative and c was negative -a*-c= ac
Of course positive times positive equals negative so if a and c were positive we could do
a*c= ac

A student used the proportion n/100 = 5/26 to find 5% of 26. What did the student do wrong?
Given:
A student used the proportion [tex]\dfrac{n}{100}=\dfrac{5}{26}[/tex] to find 5% of 26.
To find:
The student's mistake.
Solution:
Let 5% of 26 be n. Then,
[tex]n=\dfrac{5}{100}\times 26[/tex]
On dividing both sides by 26, we get
[tex]\dfrac{n}{26}=\dfrac{5}{100}[/tex]
So, the proportion used by the student was incorrect. The denominators of the proportion are interchanged.

You take a 200 milligram dosage of aspirin. During each subsequent hour, the amount of medication in your bloodstream decreases by about 35% each hour. What level of aspirin (mg) will be in your bloodstream in 4 hours. NEED ANSWER URGENT!!!
Answer: The level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.
Step-by-step explanation:
If the amount is decreasing by r%, then the final amount is given by :-
[tex]A=P(1-r)^t[/tex]
, where P = initial value , t= time
Given: P= 200 milligram, r= 35% = 0.35, t= 4 hours
The level of aspirin (mg) will be in your bloodstream in 4 hours = [tex]200(1-0.35)^4[/tex]
[tex]=200(0.65)^4\\\\=200\times 0.17850625\\\\=35.70125\approx35.70 \ mg[/tex]
Hence, the level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Wanda has three times more shirts than her brother, Will. The equation a = 3b, where a represents the number of shirts Wanda has, and b represents the number of shirts Will has, shows this relationship. If Wanda has 24 shirts, how many shirts does Will have?
Answer:
8 shirts
Step-by-step explanation:
Given the equation a = 3b, where
a = the number of shirts Wanda has
b = the number of shirts Wanda's brother (Will) has
Hence if Wanda has 24 shirts then
24 = 3b
Divide both sides by 3
24/3 = b
b = 8 shirts
Will has 8 shirts.

8 shirts
