Nolan gave out a survey to some students in his school about their favorite color. Students could choose between red and purple. 238 of those surveyed said their favorite color was red. 66% of the students surveyed said their favorite color was purple. How many students were surveyed in total?
Answer:
700
Step-by-step explanation:
100%-66%=34%
34% equals the 238 that is red
238÷34%=7 people per percentage
7×66%= 462 students that chose purple
462+238=700 which should be the total amount of people surveyed.

Solve for x: −2(x + 3) = −2x − 6 NEED HELP PLZ:(
A: 0
B: 3 C:All real numbers
D:No solution
Answer:
The answer is C:All real solutions
Step-by-step explanation:
here are the steps in case u need them :)
Step 1: Simplify both sides of the equation.
−2(x+3)=−2x−6
(−2)(x)+(−2)(3)=−2x+−6(Distribute)
−2x+−6=−2x+−6
−2x−6=−2x−6
Step 2: Add 2x to both sides.
−2x−6+2x=−2x−6+2x
−6=−6
Step 3: Add 6 to both sides.
−6+6=−6+6
0=0
Answer:
C: All real numbers.
Step-by-step explanation:
-2 ( x + 3 ) = -2x -6
-2 times x, -2 times 3
-2x -6 = -2x -6
Add 6
-2x -6 +6 = -2x -6 +6
-2x = -2x
same as....

Credit card A is running a promotion where they will charge 0% interest for the first year, and then 0.8% compounded continuously after that. Credit card B has an interest rate of 0.7%, also compounded continuously. If you are going to make a $500 purchase and plan to not make a single payment for 2.5 years, which credit card should you go with? Write the equation showing the total balance at the end of 2.5 years for that card. How much money invested at 5% compounded continuously for 3 years will yield $820
Answer: 0.1
Step-by-step explanation:
your going to substact credit card a and b and then what ever you get will be your answer

Find the answer for x.
Answer:
x=25
Step-by-step explanation:
since this is a triangle you would add up all the measure of this and set it equal to 180. 90 is the side with the box. so it would be 2x+15+x+90=180 then solve for x and you would get your answer.

Error Analysis: Find, describe & correct the error that a student has made while solving the equation: LaTeX: 4=-2\left(x-3\right)4 = − 2 ( x − 3 ) Step Number Equation 1 LaTeX: 4=-2\left(x-3\right)4 = − 2 ( x − 3 ) 2 LaTeX: 4=-2x-64 = − 2 x − 6 3 LaTeX: 4+6\:=\:-2x\:-\:6\:+\:64 + 6 = − 2 x − 6 + 6 4 LaTeX: 10\:=\:-2x10 = − 2 x 5 LaTeX: \frac{10}{-2}=-\frac{2x}{-2}10 − 2 = − 2 x − 2 6 LaTeX: -5=x
Given:
[tex]4=-2\left(x-3\right)[/tex]
To find:
The error that a student has made while solving the equation.
Solution:
We have,
[tex]4=-2\left(x-3\right)[/tex]
Using distributive property, we get
[tex]4=-2(x)-2(-3)[/tex]
[tex]4=-2x+6[/tex]
Subtract 6 from both sides.
[tex]4-6=-2x+6-6[/tex]
[tex]-2=-2x[/tex]
Divide both sides by -2.
[tex]1=x[/tex]
The value of x is 1.
In step 2, the distributive property is not used properly because when -2 is distributive with -3 then we get 6 instead of -6.
Therefore, the student has made error in step 2.
Using Oliver’s table, how can you find the unit rate?
Answer:
Is there a table I can see if I'll be able to help
Answer:
Oliver’s table indicates that for every increase of 2 strides, the distance he travels increases by 7 feet. So, the change in distance divided by the change in stride gives the unit rate.

I NEED HELP WITH THIS ASAP!!! FOR BRAINLIEST LASTQ
Answer:
A.
Step-by-step explanation:
It's literally the same equation written in reverse, which according to the commutative property, can be done.
Answer: A
Step-by-step explanation:
For this problem, we know that A is the correct answer. A is the same as the given expression because it is the same, but the order is switched. When you multiply both of them, you would get the same answer.
We can eliminate B because [tex]\frac{2}{5}[/tex] should be positive, not negative.
We can eliminate C because the fraction should be [tex]\frac{2}{5}[/tex], not [tex]\frac{5}{2}[/tex].
We can eliminate D because (-1×-7) given you 7, not -7.
Therefore, A is the right answer.
The point Q (5,3) is translated 2 units left. What are the coordinates of the resulting point Q
Answer:
(3,3)
Step-by-step explanation:
Since it's to the left, and not up or down at all, the y-value does not change. The x-value, however, is affected. Since it's to the left, it is decreasing in value by 2 points. If it were to the right, it would increase in value to (7,3), since it'd be going further away from (0,0).
Answer:
Q = (3,3)
Step-by-step explanation:
Moving the point left moves the x value down 2.
5-2=3
Therefore, Q = (3,3)
the value of 1 by 3- 1 by 2=
Answer:
the value of 1 by 3- 1 by 2 is 1
Step-by-step explanation:
it is one because 1 by 3 is 1*3
that equals to 3
then you do 1 by 2 (aka 1*2)
then it is 3-2 which equals to 1
what property is 4x + 8 = 28
Answer:
x=5
Step-by-step explanation:
4x + 8 = 28,
it's rather straight forward,
you would subtract 8 from the left side,
doing the same on the right.
now you have
4x = 20
x= 20/4
x=5
hope this helps.

When x+2 = 1/5y is written in standard form, what is the value or B
Answer:
B=-1
Step-by-step explanation:
Standard form is Ax+By=C.
In this case, Ax is x, By is 1/5y, and C is +2.
To isolate the 2 (the C), subtract x from both sides of the equation:
x+2=1/5y
-x -x
2=-x+1/5y.
Now, the value of B, the x value, is -1.
Factor the following trinomial completely, or state that the trinomial is prime.
3x^2+10xy + 8y^2
Answer:
(3x + 4y)(x + 2y)
Step-by-step explanation:
3x^2+ 10xy + 8y^2
All signs are positive, so we'll only look at positive factors of 3 and 8.
3 factors into 3 and 1.
8 factors into 4 and 2, and it also factors into 8 and 1.
I like to try closer factors in value, so I'll start with 4 and 2 for 8.
Try:
(3x + 2y)(x + 4y) = 3x^2 + 12xy + 2xy + 8y^2 = 3x^2 + 14xy + 8y^2
The middle term does not work. Switch 2y and 4y and try again.
Try:
(3x + 4y)(x + 2y) = 3x^2 + 6xy + 4xy + 8y^2 = 3x^2 + 10xy + 8y^2
It works.
Answer: (3x + 4y)(x + 2y)
