Answer:
x = -6
Step-by-step explanation:
Equations
Solve the equation:
x + 6 = -x - 6
We must find the value of x that makes the identity above true.
Let's join all the variables on the left side and the numbers on the right side.
Adding x:
x + 6 + x = -x - 6 + x
The variables cancel out on the right side:
2x + 6 = -6
Subtracting 6:
2x + 6 - 6 = -6 -6
The 6 and -6 are canceled out:
2x = -12
Dividing by 2:
x = -12/2
x = -6

A student's cost for last semester at her community college was $2000. She spent $280 of that on books. What percent of last semester's college costs was spent on books?
Answer:
14%
Step-by-step explanation:
A way I usually do it is with a fraction setup.
280/2000 = ?/100
multiply 280 by 100, and you get 28000. divide this by 2000, and you get 14!

3y - 9x = -6
4y - 12x = -8
Answer:
21x = 14
x = 1.5
Step-by-step explanation:
(-4)3y - 9x = -6
(3)4y - 12x = -8
-12y-9x=-6
12y-12x=-8
0 -21x = -14
-21x/- = -14/-
21x = 14
I need help with geometry
Answer:
N, M, P
Step-by-step explanation:
The smallest angle is opposite the shortest side
The largest angle is opposite the longest side
Thus
∠ N is opposite the shortest side MP = 10
∠ P is opposite the longest side MN = 18
From smallest to largest, then
∠ N, ∠ M, ∠ P

Each pair of polygons is similar. Find the value of x.
Answer in fraction form: x = 55/4
Answer in decimal form: x = 13.75
Both forms are equivalent, but they say it in a slightly different way.
===========================================================
Work Shown:
AC/QY = CD/YW
(x+5)/15 = 5/4
4(x+5) = 15*5
4x+20 = 75
4x = 75-20
4x = 55
x = 55/4
x = 13.75
------------
Explanations:
The first step is possible because the polygons are similar. Similar figures have their corresponding sides be in the same proportion or ratio. Note how side AC has the double red angle (at point A) and a single red angle (point C). The side QY has the same idea in the same order. This is why AC corresponds to QY. The ratio AC/QY is the same as CD/YW.In the second step, I plugged in the expressions that the diagram shows. This is the substitution property.On step 3, I cross multiplied. The general format is A/B = C/D cross multiplies to A*D = B*C.The total (after-tax) cost of a laptop computer is $1571.02. The local sales tax rate is 5.3%. What is the retail (pre-tax)
price?
Answer:
Retail price of laptop = $1491.94
Step-by-step explanation:
Price of laptop after tax = $1571.02
Local sales tax rate = 5.3%
Total price = Pre tax price + tax = (100+5.3)%
Total price = 105.3%
Let,
x be the pre-tax price
105.3% of x = 1571.02
[tex]\frac{105.3}{100}x=1571.02[/tex]
1.053x = 1571.02
[tex]\frac{1.053x}{1.053}=\frac{1571.02}{1.053}\\x=1491.94[/tex]
Retail price of laptop = $1491.94

True or false To find 7% of a number, multiply the number by 0.7
Answer:
true and it also depends on what question it is
Step-by-step explanation:
because 7% = 0.07 when doing a mathematical question it will help you a lot if you turn 7% into a decimal 0.07 and it will be more easier than doing it as a percentage.

If there are 68 people in a survey (everyone is either an adult or kid) and 60% are kids, how many adults are there?
Answer:
about 27 adults
Step-by-step explanation:
68 x 60% would find you kids
100% is 68, so, 100 - 60 = 40%
The remaining 40% are adults.
68 x 0.4 = 27.2
about 27.2 adults
Answer:
27 adults (rounded)
27.2 (not rounded)
Step-by-step explanation:
60% of 68 is 40.8
68 - 40.8 = 27.2
since .8 is bigger than .2 , 40.8 will be 41 and 27.2 will be 27
41 kids
27 adults
please help with this TWO ANSWERS required
Answer:
a) The equation of V and W
V = k W
b) The value of V = 666.6
Step-by-step explanation:
Step(i):-
Given that V is inversely proportional to W
V∝ W
⇒ V = k W
⇒ 40 = k (0.9)
⇒ [tex]k = \frac{40}{0.9} = 44.44[/tex]
Step(ii):-
Given that W = 15 and k = 44.44
we have to find the value is 'V'
V = k W
⇒ V = 44.44 × 15
⇒ V = 666.6

Which of the functions below is an inverse of the quadratic function f(x) = x2 - 3 ?
Answer:
the inverse of the quadratic function [tex]f(x) = x^2 - 3[/tex] is [tex]\mathbf{f^{-1}(x)=\pm \sqrt{x+3}}[/tex]
Step-by-step explanation:
We need to find inverse of the quadratic function [tex]f(x) = x^2 - 3[/tex]
Let
[tex]y=x^2-3[/tex]
Replace x and y
[tex]x=y^2-3[/tex]
Now, we will solve for y
Adding 3 on both sides
[tex]x+3=y^2-3+3[/tex]
[tex]x+3=y^2[/tex]
Taking square root on both sides
[tex]\sqrt{y^2}=\sqrt{x+3}\\y=\pm \sqrt{x+3}[/tex]
Now replace y with [tex]f^{-1}(x)[/tex]
[tex]f^{-1}(x)=\pm \sqrt{x+3}[/tex]
So, the inverse of the quadratic function [tex]f(x) = x^2 - 3[/tex] is [tex]\mathbf{f^{-1}(x)=\pm \sqrt{x+3}}[/tex]
