Answer:
x =5.5
Step-by-step explanation:
The directions say to use x for the number.
"take 10 away from"
x - 10
"then square the result"
(x - 10)^2
"I get the same answer" means the two expressions will be equal to each other.
"if I square my number"
x^2
"then subtract 10 from the result"
x^2 - 10
SET EQUAL TO EACH OTHER.
(x - 10)^2 = x^2 -10
Multiply on the left side.
x^2-20x+100 =x^2-10
subtract x^2 from both sides.
-20x + 100 = -10
subtract 100.
-20x = -110
divide by -20
x = 11/2 or 5.5
CHECK:
(5.5-10)^2=20.25
5.5^2 - 10=20.25
The number would be equal to x =5.5
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The directions say to use x for the number means x - 10
"then square the result" means (x - 10)^2
"I get the same answer" means the two expressions will be equal to each other.
"if I square my number" means x^2
"then subtract 10 from the result" means x^2 - 10
therefore,
(x - 10)^2 = x^2 -10
Now Multiply on the left side.
x^2-20x+100 =x^2-10
Then subtract x^2 from both sides.
-20x + 100 = -10
-20x = -110
x = 11/2 or 5.5

18% of cats who like
Cat food A' also like
Cat food 'B'. If there
are 500 cats who like
Cat food 'A', how many
like Cat food B?
Answer
-
95
28
90
Answer: 90
Step-by-step explanation:
To easily solve this, just take .18 x 500. We know we can convert a percent to a decimal by moving the decimal point two places to the left. This allows us to multiply .18 x 500 to get a final answer of 90

(7 - 4n) - 6
Answer:
24n-42
Step-by-step explanation:
by factoring, you take whatever is on the outside and multiply by each of the inside, so.
7x-6=-42
and
-4nx-6= 24n (since we multiply 2 negatives, it becomes positive)
Answer:42-24n

Bananas cost $0.50 each, and apples cost $1.00 each.
(a) Elena would like to spend exactly $3.50 on buying fruits. If she buys 1 banana, how
many apples can she buy?
(b) Is it possible for Elena to buy 2 bananas, if she wants to spend exactly $3.50? Why or
why not?
Answer:
(a) 3 apples (b) no
Step-by-step explanation:
(a) 1 bannana = 0.50
3 apples = 3.00
total = 3.50
(b) Not possible because 2 bannanas = 1 dollar 3 bananas = 1.50 then 1.50 + 2.00 apples = 3.50

geometry due tonight
Answer:
A: 5 CM
B: 2.5 CM
C: ABC approx. equal to EDC (I'm not 100% sure on this one, but it makes most sense.)
I can't help you with number four, I'm sorry. I hope someone else comes along and helps with that!
Step-by-step explanation:
The symbol being used means "approximate equality" meaning that the two angels are alike. So in A, the two sides on the shapes are both 5 cm. On B, since it is half of that side, it would be half of five, making it 2.5 cm. For C, the middle letter is the one touched second. Therefore when you draw the shape it makes the most sense that it's ABC approx. equal to EDC. Not to mention that ABC and the next angel has to match, so since the C is last, it also matches in that spectrum.
For D, I don't know the terminology, I'm sorry.
What is solving inequalities
An inequality is a comparison of expressions by either "less than" (<), "less than or equal to" (<=), "greater than" (>), or "greater than or equal to" (>=). Note that Html does not support the standard symbols for "less than or equal to" and "greater than or equal to", so we use <= and >= for these relations.

Find the length and width of rectangle CBED, and calculate its area.
Answer:
170 units
Step-by-step explanation:
60+60+25+25=170
The 60 and 60 can be found by adding the length, 20+35+5.
The 25 and 25 can be found by taking 55+8-(30+8) for the widths.
Answer:
Step-by-step explanation:
Length = DE =OP
OP = 5 + 20 + 35 = 60 ft
Length of the rectangle CBED = 60ft
Width CD = CJ - (DG +GJ)
= 55 - (8 + 30)
= 55 - 38
= 17 ft
Area of CBED = length * width
= 60 * 17
= 1020 ft²

Find a polynomial that represents the area of the
square.
Answer:
16x² + 72x + 81
Step-by-step explanation:
The area of a square is [tex]s^2[/tex], where s = side. In this case, we're given the side length as 4x + 9.
[tex](4x+9)^2 = (4x+9)(4x+9)[/tex] [tex](4x+9)(4x+9)=(4x)(4x)+(4x)(9)+(9)(4x)+(9)(9)[/tex] [tex]16x^2+36x+36x+81[/tex] [tex]16x^2+72x+81[/tex]Therefore, the answer is 16x² + 72x + 81.

16w+2 simplified
Factor the expression by the greatest common factor
Answer:
2(8w + 1)
Step-by-step explanation:
Look on either side of the plus sign. What ever you see that is common is a common factor. In this case it is also the greatest common factor.
2 appears on both sides of the plus sign.
2(16w/2 + 2/2)
Hello.
Remember that factoring is the opposite of distributing.
Factoring looks like this:
ab+ac=a(b+c) [tex]\longmapsto[/tex] factor out the greatest common factor
In this case, the Greatest Common Factor is
2
Now, divide both terms of the expression by 2.
2(8w+1)
Is this right? We can easily check by using the Distributive Property and distributing 2. Then, we can compare both expressions and see if we ended up with the original expression.
16w+2
See? We have the original expression.
I hope it helps.
Have an awesome day.

the values of q decrease as the values of p increase.
this indicates an inverse relationship between the quantities, that is
q = [tex]\frac{k}{p}[/tex] ← k is the constant of variation
to find k use any ordered pair from the table.
using q = 16 when p = 3 , then
16 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
48 = k
q = [tex]\frac{48}{p}[/tex] ← equation of variation
(4)
the values of q increase as the values of p increase.
this indicates the quantities are in direct variation, that is
q = kp ← k is the constant of variation.
to find k use any ordered pair from the table.
using q = 2 when p = 6 , then
2 = 6k ( divide both sides by 6 )
[tex]\frac{2}{6}[/tex] = k , that is
k = [tex]\frac{1}{3}[/tex]
q = [tex]\frac{1}{3}[/tex] p ← equation of variation
