The difference between 1/3 of a certain number and 1/4 of the same number is 3. what is that number?
Answer:
36
Step-by-step explanation:
(1/3)x - (1/4)x = 3
multiply by 12 to clear the fraction
4x - 3x = 36
x = 36

Answer:
f(x)= -1/2x+1
Step-by-step explanation:
The slope is negative because the graph goes up then to the left, making it negative. The slope is also 1 half because the slope is measured by rise over run. It rises once, then goes to the left twice. 1/2. It's also plus 1 because the graph cross the y-intercept at positive 1.

approximate the number ∛-12 to the nearest a) integer and b) tenth
Answer:
Below in bold.
Step-by-step explanation:
∛-12
The nearest cube to -12 is -8 ( -27 is the next after -12)
a) The answer is -2.
b) we can do this by trial and improvement
It must be between -2 and -3, closer to -2 than 3 so first we guess -2.1
(-2.1)^3 = -9.261
(-2.2)^3 = -10.648
(-2.3)^3 = `2.167 - very close
Answer is -2.3 .
Solve for y,if 3+3y=1–13y
Step 1: Simplify both sides of the equation.
3+3y=1−13y−9
3+3y=1+−13y+−9
3y+3=(−13y)+(1+−9)(Combine Like Terms)
3y+3=−13y+−8
3y+3=−13y−8
Step 2: Add 13y to both sides.
3y+3+13y=−13y−8+13y
16y+3=−8
Step 3: Subtract 3 from both sides.
16y+3−3=−8−3
16y=−11
Step 4: Divide both sides by 16.
16y
16=−11/16
y=−11/16
Answer:
y=−11/16
I basically just have to find the angles but I also want to understand so if you could explain?
9514 1404 393
Answer:
c = 108°
d = 106°
Step-by-step explanation:
There are 2 basic rules involved here. From them, a number of others can be derived in order to simplify some calculations.
angles forming a linear pair are supplementary (total 180°)interior angles of a triangle total 180°The derived relations we can use in this problem are ...
vertical angles are congruentan exterior angle of a triangle is equal to the sum of the opposite interior angles__
cThe vertical angle to 78° is one of two remote interior angles with respect to exterior angle c. The other is the one marked 30°. That means ...
c = 78° +30* = 108°
__
dAngles d and 30° are two of the three angles in the largest triangle. The third is the vertical angle to 44°, so it is 44°. The sum of angles in that triangle is 180°:
d + 30° +44° = 180°
d = 180° -74° = 106°

which pair of terms are not like terms?
A. 4a and 7a
B. 3p^2q and -p^2q
C. 2mn and mn^2
D. -x and 3x
Answer:
C.
Step-by-step explanation:
Like terms must have exactly the same variables and exactly the same exponents.
In C., you have mn and mn^2. That makes the variable parts not the same, so they are not like terms.

12 napkins costs 20 cents
What is the rate AND unit rate of this ratio?
Answer: in explanation
Step-by-step explanation:
Rate is simplest form, so 3 napkins for 5 cents.
Unit rate is for 1 x value, so 1 napkin for 0,6 cents.

Is the expression a polynomial? If yes, write in standardform, if not state why not
1.
[tex]\frac{2x+3}{x^{2} }[/tex]
2.
[tex]2x+5x^{2} -99[/tex]
3.
[tex](\sqrt{8x^{3}}) +2x^{4}+2+x[/tex]
4.
[tex]15x+4x^{-2}[/tex]
5.
[tex]-3x^{4} +7x+12x^{2}[/tex]
Answer:
Step-by-step explanation:
1) Not a polynomial. Because x² is in the denominator.
2) Yes, it is a polynomial.
Standard form: 5x² + 2x - 99
3) Not a polynomial.
[tex]\sqrt{8x^{3}} = (8x^{3})^{\frac{1}{2}} = 8^{\frac{1}{2}}x^{\frac{3}{2}}[/tex] .
Power of x is a fraction. so , it is not a polynomial.
4) Power of x is (-2). Power of x should not be a negative integer. SO, it is not a polynomial.
5) Yes:
Standard form: -3x⁴ + 12x² + 7x
can someone help me please
Answer:
#5) Its line “k”
Well to solve this you need to know what negative slopes are.
They decrease from height from left to right
And also a slope is always calculated like this
rise -> run
Think of it like a bed.
You have to wake up which means you have to rise and then you run to do whatever it is you gotta do.
Rise is going vertical and run is going horizontal.
So for line K you have it because since its negative its -3/1 so technically its -3 rise(basically fall since its negative), 1 run (right).
#6) 1/2 is the slope of line N. Or (c)
Well n is a potsive slope so we can automatically remove a and b.
And we can count like this, it started from the orgin it looks like (but you can use any given point really) and then just follow it, rise 1 and run 2. Rise 2 and run 3 doesn’t work so it has to be 1.2 or (c)
proves that the sum of
5 consecutive natural numbers is divisible by 5
Answer:
n = 5m + 10 = 5(m + 2), since m + 2 is an integer, then the n is divisible by 5.
Step-by-step explanation:
Answer:
Natural numbers are simply positive integers. For now, refer to the middle number (the third number), as x. Thus, the numbers are: x - 2, x - 1, x, x + 1, and x + 2. Simply add all these numbers to get 5x, a number that is divisible by 5. As such, you can conclude that any 5 consecutive numbers are divisible by 5, and the quotient would be the third, or middle number.
Hope it helps :) and let me know if you want me to elaborate.
