9-17x-5-4x=7
Answers
Answer:
x = -1/7
Step-by-step explanation:
Solve for x
9-17x-5-4x=7
Combine like terms
-21x +4 = 7
Subtract 4 from each side
-21x-4+4 = 7-4
-21x = 3
Divide each side by -21
-21x/-21 = 3/-21
x = -1/7
Check
9 - 17(-1/7) -5 -4(-1/7) =7
9 + 17/7 -5 + 4/7 =7

The difference between two numbers is 10 and
their sum is four times the smaller number.
Find the two numbers.
Answers
Answer:
x = 10
y = 5
Step-by-step explanation:
Let the two numbers be x and y
Difference between the two is 10
x-y = 10
Sum;
x+ y is four times the smallest number
Let the smaller number be y
x+ y = 4y
Subtracting equation ii from i
-2y = 10 -4y
4y-2y = 10
2y = 10
y = 10/2
y = 5
Recall;
x-y = 10
x = 10 + y
x = 10 + 5 = 15

On a certain hot summer's day, 73 people used the public swimming pool. The daily prices are for children are $1.25 and for adults are $2.25. The receipts for admission totaled $126.25. How many children and how many adults swam at the public pool that day?
Answers
Answer:
There were 35 children and 38 adults at the pool that day.
Step-by-step explanation:
You can use substitution to solve this answer. When solving equations with substitution, ask yourself "how many?" and "how much?" to create two equations:
1.25c+2.25a=126.25 (this equation tells us the dollar value)
c+a=73. (this equation tells us quantity, or how many)
1. Solve for 1 variable and plug it into the other equation.
a=73-c -----> 1.25c+2.25(73-c)=126.25
2. Simplify the equation above.
1.25c+164.25-2.25c=126.25
3. Simplify even more:
-1c+164.25=126.25
4. Subtract 164.25 from both sides to get:
-1c=-38
5. Divide both sides by -1.
c=38 (this means that there are 38 children)
6. Plug the new value for c back into the equation c+a=73.
38+a=73
7. Subtract 38 from both sides to solve for a:
a=35 (this means that there are 35 adults)
I hope this helps!

Rita feeds her dog 2/5 pounds of dog food for each meal Rita has just bought 10 punds of dog food. for how many meals will this food last
Answers
Answer:
25 meals
Step-by-step explanation:
If Rita feeds her dog 2/5 pounds of dog food for each meal, this means;
2/5 pounds = 1 meal
To get the number of meals she will feed if she buys 10 pounds, we will say;
10 pounds = x meals
Divide both equations to get x;
(2/5)/10 = 1/x
Cross multiply;
2/5 x = 10 * 1
2x/5 = 10
2x = 50
x = 50/2
x = 25
Hence the 10pounds food will last 25 meals

Write the contrapositive in if-then form.
O If 2x–5=5, then 4x - 6=14.
If 4x -6=14, then 2x-5=5.
If 2x – 5≠5, then 4x - 6≠14.
If 4x - 6≠4, then 2x–5≠5.
Answers
Answer:
we conclude that:
If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.
Step-by-step explanation:
We know that the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p".
In other words, it is symbolically represented as:
' ~q ~p is the contrapositive of p q '
For example, the contrapositive of "If it is a rainy day, then they suspend the match" is "If they do not suspend the match, then it won't be a rainy day."
Given
p: 2x -5=5
q: 4x-6=14
As the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p
Thus, we conclude that:
If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.

Point P is located at (–3, –2). P is reflected across the x-axis to create P'. What quadrant is P' in?
Answers
The quadrant of P' is (-3 , 2).
Here,
Point P is located at (–3, –2).
Point P is reflected across the x-axis to create P'.
We have to find the quadrant of P'.
What is Reflection across x-axis?
A point after reflection across the x-axis, the x- coordinate remains the same but y - coordinate is taken to be the additive inverse.
Now,
Point P is located at (–3, –2).
Point P is lie on third coordinates.
And, P is reflected across the x-axis to create P'.
Hence, Point P' is lie on second coordinates.
Since, The rule of the reflection across x- axis is,
(x, y) → (x, -y)
Hence, Quadrant of P' = (-3, -(-2)) = (-3, 2)
Therefore, The quadrant of P' is (-3 , 2).

The option that negates the given statement is; F: Two segments do not have the same measurement.
What is the Negation of a statement?In Mathematics, the negation of a statement simply means the opposite of the given mathematical statement. Thus, “X” is a statement, then the negation of statement X is represented by ~X.
Now, we are given the statement;
"Two segments are the same measurement."
Now, for two segments to be the same measurement it means that they are equal and congruent and could possibly measure the same degree, However, it can never mean that they do not have the same measurement.
Thus, the option that negates the given statement is; F: Two segments do not have the same measurement.

Answer: x = 5.625
Step-by-step explanation: The triangles are similar; the side lengths of the large triangle are proportional to the lengths of the small triangle. The corresponding parts are proportional.
Use proportion. The total length of side FV is 16.
6:16 = x:15 . or 6/16=x/15
cross multiply 15 × 6 = 90, then divide 90/16
90/16 = x

Find the measure of the missing angle
Answers
Answer: b=112 degrees and c=68
Step-by-step explanation:
Answer:
b = 112, c = 68
Step-by-step explanation:
The angle of a line is 180 degrees.
If an angle is 112, 180-112=68 so that blank space will be 68 degrees.
180-68=112, so b=112.
Since b is 112, we now that c is 68.
LMN with vertices L(4,8), M(4,3) and N(8,8) is rotated 270 clockwise about the origin what are the coordinates of L’?
Answers
Coordinates of L after rotation are (-8,4)
What are the rules of 270 degrees rotation of coordinates about the origin?
Assuming that the rotation is about (0,0)
then after 270° clockwise rotation (x, y) becomes (-y, x)
and after 270° anticlockwise rotation (x, y) becomes (y,-x)
Given that LMN with vertices L(4,8), M(4,3) and N(8,8) is rotated 270° clockwise about the origin
Then for L(4,8) as the rotation is 270° clockwise then
(x, y) = (4,8)
and after 270° clockwise rotation (x, y) becomes (-y, x)
Therefore new coordinates of L are (-8,4)

Find the value of x.
Answers
Answer:
x = 5.
Step-by-step explanation:
x is the radius of the circle.
The line of length 4 bisects the chord of length 6 into 2 line segments of length 3.
If we draw a line from the centre to where the chord of length 6 meets the circle we have another radius.
This is also the hypotenuse (h) of a right triangle, so we have a right triangle whose legs are 3 and 4, then:
h^2 = 4^2 + 3^2 = 25
h = 5
x = 5 (as x and h are both radii).
