Answer:
x=3
Step-by-step explanation:
If we know that y=x-1, we can just substitute it and replace y with (x-1)
so 2x+y=8 becomes:
2x+(x-1)=8 and we simplify that into:
3x-1=8, add 1 on both sides to make it:
3x=9, divide 3 on both sides
x=3

at a certain college, the ratio of men to women is 6 to 5. If there are 1,500 men how many women are there?
Answer:
1250 women
Step-by-step explanation:
1500 / 6 = 250
250 x 5 = 1250
hope this helps
Answer:
There are 1,250 women
Step-by-step explanation:
If the ratio of men to women is 6 to 5, and there are 1,500 men, the actual ratio of men to women is 1,500 to x, where x is equal to the amount of women at the college.
Since 6/5 is equal to 1,500/x, you cross multiply to find that 7,500 is eual to 6x.
Divide both sides by 6 to find that x is equal to 1,250 women.

Scientific notation of 141700000
Answer:
1.47 * 10^8Step-by-step explanation:
Given the value 141700000, we are to express in scientific notation
The standard form is expressed as A * 10^n
A is any integer between 1 and 10
n is also any integer
141700000.= 1.47 * 10^8
Note that the decimal point was shifted back 8 times, main reason the power is 8
A cylindrical container has a diameter of 5 inches and a height of 12 inches. The container will be wrapped and delivered as a gift. What measurement is closest to the amount of wrapping paper needed to cover the container without overlap?
Answer:
Step-by-step explanation:
1. Write your formula
2. Plug it in
3. Solve
these steps will help you out with all of your surface area problems.
Like this
Since it is a diameter you have to divide the diameter by 2. That will get you your radius. Then you write your formula for a cylinder. Your formula is...
V = Bh (Pie is also known as 3.14)
your big (B) is (pie times r squared) Then you add your height.
so your formula will look like this...
V = pie times r squared...
the full formula will be...
V = (3.14) times (2.5 squared) times the height which in this case is (12)
everything together will be...
V = (3.14) (2.5^2) (12)
all you have to do is multiply all of that and you will get your answer.
The answer is...
V = 236 inches ^2 (Just a tip, the ^ sign means to the power of)

The product of 8 and c is 72.
Answer: If your asking what c is its 9
Step-by-step explanation: How I did it was I did 72/8, which is 9. How I checked was I did 8*9 and I got 72
C is 9 if you multiply 8 and c to get 72.
On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adults.The receipts for admission totaled to $1249.50. How many children and how many adults swam at the public pool that day?
Answer:
120 children and 388 adults bought tickets for the swimming pool
Explanation:
Create two simultanous equations:
Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being
c
+
a
=
508
then, you now create a second equation for the prices of the tickets.
(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected
so:
1.75
c
+
2.25
a
=
1083.00
now we still know, that
a
=
508
−
c
so we can substitute it into the second formula
1.75
c
+
2.25
(
508
−
c
)
=
1083
now its just simple algebra
1.75
c
+
1143
−
2.25
c
=
1083
60
=
0.5
c
so:
c
=
120
now we know, that 120 children went to the swimming pool.
and we still have the formula from before:
a
=
508
−
c
so
a
=
388

PLEASE ANSWER COMPLETE QUESTION. WILL MARK BRAINLIEST FOR BEST ANSWER. QUESTION IS ATTACHED.
9514 1404 393
Explanation:
A linear system of two equations in two variables will be a dependent system. This means both equations reduce to the same equation. The equations will be different only until they are reduced to the same form.
Here is one possible set of equations. The first is in slope-intercept form. The second is in point-slope form.
y = 3x +1y -7 = 3(x -2)If we subtract the first equation from the second, we get ...
(y -7) -(y) = (3(x -2)) -(3x +1)
-7 = 3x -6 -3x -1 . . . . . eliminates y
-7 = -7 . . . . . . . . . true for all values of x
There are an infinite number of solutions.
The ordered pairs shown below are on the same line. (6,4) (12.6) Which equation describes the relationship between the x-coordinates and y-coordinates in the ordered pairs?
a. y = 3x - 14
B.y = 3x - 6
C. y= 1/3x + 2

Which statement about f(x) = 2x2 – 3x - 5 is true?
A The zeros are - and -1, because f(x) = (x + 1)(2x + 5).
2
5
B The zeros are - and 1, because f(x) = (x - 1)(2x + 5).
2
C The zeros are -1 and, because f(x) = (x + 1)(2x-5).
The zeros are 1 and, because f(x) = (x - 1)(2x - 5).
9514 1404 393
Answer:
C. The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).
Step-by-step explanation:
The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.
The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.
Additionally, the x-term needs to match the result of multiplying out the factors.
B. (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)
C. (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)
The factors of C are zero when x=-1, x=5/2.

Answer:

Step-by-step explanation:
THREE expressions equivalent to –81x+27.
Hey there!
One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us [tex]\frac{-81x+27}{3}[/tex]. If we simplify this, we get [tex]-27x+9[/tex].
Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us [tex]\frac{-81x+27}{21}[/tex]. If we simplify this, we get [tex]-3x+1[/tex].
One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us [tex]1(-81x+27)+0[/tex].

What is the slope of a line parallel to the line x-3y=4
At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 12 m. The inner edge of the sidewalk is a circle with a radius of 8 m.
Write and simplify an expression for the exact area of the sidewalk.
Find the approximate area of the sidewalk. Use 3.14 to approximate π.
Answer:
The answer would be 251.2 for the side walk if the radius for the whole circle is 12 and the small circle's radius would be 8. Only for the answer with the 8 m and 12 m radius NOT the 11m and 9 m
The equation would be:
144 x 3.14 - 64 x 3.14 = 251.2
Step-by-step explanation:
First, you need to find out what the whole circle is:
The whole circle is 452.16
Then, find the inner circle :
8 x 8 x 3.14
200.96
Last, subtract the whole by the inner:
452.16 - 200.96 = 251.2
hope this helps!
please help does anyone know the answer to this?
Answer:
M = 95°
N = 67°
Step-by-step explanation:
180 - 162 = 18°
6y + 5 + 4y + 7 + 18 = 180
10y + 30 = 180
10y = 150
y = 15
M: 6(15) + 5 = 95°
N: 4(15) + 7 = 67°
Verification: 95 + 67 + 18 = 180° (correct)

Step-by-step explanation:
Use foil to expand this value.
(4m+3)(m+2)
Multiply the first terms in the two brackets.
Then multiply the two outer terms.
Followed by multiplying the inner terms.
Finally multiply the last terms
= (4m+3)(m+2)
4m² + 8m + 3m + 6
4m² + 11m + 6

Jane needs to fix a piece of broken siding on the side of her house. The top of the
ladder is placed is 8 feet high above the ground and the base of the ladder will be
placed 6 feet away from the house.
What is the length of the ladder? Round to the nearest whole number.
Answer:
ladder length = 10 feet
Step-by-step explanation:
using the Pythagorean theorem:
8² + 6² = length²
64 + 36 = length²
length² = 100
length = 10 feet
