A group is going to a state fair. If childrens tickets are $7.50 per child and adult tickets are $12 per adult, how many of each can go to the fair for $200? Write a linear equality, graph it, and show several solutions on graph. !! Help
Answers
Let c = children tickets
Let c = children tickets Let a = adult tickets
Let c = children tickets Let a = adult tickets Let c to be in place of x
Let c = children tickets Let a = adult tickets Let c to be in place of xLet a to be in place of y
Answer:
7.50c+12a<or=200 (you would have a inequality since that is the maximum number you could pay and no other information is given)
the graph is above and the inequality in slop intercept format is y= -5/8x+ 16 2/3
Solutions for c: 0 <or= c <or= 26* *(since that is the maximum whole number you can have for $200)
Solutions for a: 0 <or= a <or= 16* *(since that is the maximum whole number you can have for $200)
Note: In order for find other solutions your cordatnate has to be a whole number (that is positive or zero) within the red area shaded. However there are many examples given for answer purposes.
Step-by-step explanation:
$7.50 is the price of each children tickets and $12 is the price of each adult tickets and when combined equal to $200 so you can multiply the variables to get 7.5c+12a <or= 200.
To graph the inequality there's two ways;
Way 1: Change from standerd form to slope intercept form
Place 7.50c on the right side by subtracting 7.50c on each side of the inequality (the point is to islolate a); 7.50c - 7.50c + 12y < or = 200 - 7.50c. The 7.50c on the left side cancel each other out so we'll get 12a < or =200 - 7.50c Isolate a by dividing both sides by 12; 12a/12= (200 - 7.50c)/12 that equals to a < or = -5/8c + 16 2/3 Find an appropriate scale and graph you can use the a-interpect and c-intercpt to make a line since this is less than or equal to you shade the region below the lineWay 2: Isolate your variables to get your x and y intercept
To find the a-interpect you make c equal to 0 so it would be 12a = 200Divide 12 on both sides; 12a/12 =200/12. The a-interpect is 16 2/3 To find the c-intercpt you make a equal to 0 so it would be 7.50c = 200. Graph the point on your graph Divide 7.50c on both sides; 7.50c/7.50 =200/7.50. The a-interpect is 26 2/3. Graph the point on your graph Draw a continuous line from your two points

the measure of a supplement of an angle exceeds 10 times the measure of its complement by 9. Find the measure of the angle
Answers
Answer:
81°
Step-by-step explanation:
Let the angle be x. Then,
complementary angle = 90 - xsupplementary angle = 180 - xAccording to question,
=> 180 - x - 10(90 - x) = 9
=> 180 - x - 900 + 10x = 9
=> 9x - 720 = 9
=> 9x = 729
=> x = 81
The measure of the angle is 81° (ans)
Answer:
81°
Step-by-step explanation:
Definitions
Complementary angles: Two angles whose measures sum to 90°.
Supplementary angles: Two angles whose measures sum to 180°.
Define the unknown angle
Let x be the unknown angle.Therefore:
Complement of x = 90° - x°Supplement of x = 180° - x°If the measure of the supplement exceeds 10 times the measure of its complement by 9:
⇒ supplement = 10 × complement + 9
⇒ (180 - x) = 10(90 - x) + 9
⇒ 180 - x = 900 - 10x + 9
⇒ 180 - x = 909 - 10x
⇒ 180 - x + 10x = 909 - 10x + 10x
⇒ 180 + 9x = 909
⇒ 180 + 9x - 180 = 909 - 180
⇒ 9x = 729
⇒ 9x ÷ 9 = 729 ÷ 9
⇒ x = 81
Therefore, the measure of the angle is 81°.

In mathematics, the logarithm is the reciprocal of a power. This means that the logarithm of a given number x is the exponent by which another fixed number (the base b) must be increased to get that number x. The simplest logarithm counts the number of times the same element occurs when multiplying repeatedly. The logarithm of x to base b is denoted by log b (x), or log b x without parentheses. Also, if confusion is impossible or the base doesn't matter, log x shows that even without an explicit base: B. In big O notation.

Solve for x:
1/3 |x-3|+ 4 = 10
Answers
Answer:
x=-15 and x=-15
Step-by-step explanation:
We try to move everything from the left to the right starting with the number that is further away from x, so 4. We subtract it from both sides.
1/3|x-3|+4-4=10-4
1/3|x-3|=6
Next, we have the fraction so basically, 1 is being divided by 3 so we are going to multiply both sides by three.
1/3|x-3|×3=6×3
|x-3|=18
We get rid of the absolute value signs to get
x-3=18
But we are not sure if 18 is negative so we put it like this.
x-3=-18
x-3=18
Then we add 3 from both sides.
x-3+3=-18+3
x-3+3=18+3
Which equals:
x=-15
x=21

a. What is the solution of the system? Use elimination.
x-2y+3 z = 12
2x-y-2z = 5
2x+2 y-z = 4
Answers
By elimination, the solution of the system of equations, x - 2y + 3z = 12, 2x - y - 2z = 5 and 2x + 2y - z = 4, is (4 , -1 , 2).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Given:
x - 2y + 3z = 12 (equation 1)
2x - y - 2z = 5 (equation 2)
2x + 2y - z = 4 (equation 3)
Using the elimination method, given the equations in x, y, and z, a variable should be eliminated by adding/subtracting the equations.
Adding equations 1 and 3 will eliminate the variable y.
x - 2y + 3z = 12 (equation 1)
2x + 2y - z = 4 (equation 3)
3x + 2z = 16 (equation 4)
Multiply equation 2 by 2 and add with equation 3.
2x - y - 2z = 5 (equation 2)
⇒ 4x - 2y - 4z = 10
+ 2x + 2y - z = 4 (equation 3)
6x - 5z = 14 (equation 5)
Multiply equation 4 by 2 and subtract with equation 5.
3x + 2z = 16 (equation 4)
⇒ 6x + 4z = 32
- (6x - 5z = 14) (equation 5)
9z = 18
z = 2
Substitute the value of z to either equation 4 or 5 and solve for x.
3x + 2z = 16 (equation 4)
3x + 2(2) = 16
3x = 16 - 4
3x = 12
x = 4
Finally, substitute the value of x and z to any of the first three equations, and solve for y.
x - 2y + 3z = 12 (equation 1)
4 - 2y + 3(2) = 12
-2y = 12 - 4 - 6
-2y = 2
y = -1
Hence, the solution of the system of equations is (4 , -1 , 2).

Given that R is the midpoint of YW
RY = 11x + 46 and RW = 3x + 58.
Y______________R______________W
⇒ YW = RY + RW
Since R is the midpoint of YW,
So RY = RW
Substitute the values of RY = 11x + 46 and RW = 3x + 58,
⇒ 11x + 46 = 3x + 58
Rearrange the terms of the above equation and solve for x,

The procedure for appraising an AP's n-th term is as follows: an = a + (n − 1) × dThe following is the arithmetic progression sum: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, the given sequence is; 100,117,134,151,168, ...........
The series comprises of five given terms.
Let the initial term be 'a₁' = 100.
The second term be 'a₂' = 117.
The third term be 'a₃' = 134.
And, the fourth term is 'a₄' = 151.
The AP must have the equal common difference. So,
d = a₃ - a₂
Substitute the values.
d = 134 - 117
d = 17
Thus, the computed common difference is 17.
or d = a₄ - a₃ (Substitute the values)
d = 151 - 134
d = 17
Since, a₃ - a₂ = a₄ - a₃
Thus, we can get to know that the given sequence is in AP.
Now, the 6th term is estimated as; a₆ = a₅ + d = 168 + 17
a₆ = 185
Similarly, the 7th term will be; a₇ = a₆ + d = 185 + 17
a₇ = 202
And, the 8th term will be calculated as; a₈ = a₈ + d = 202 + 17
a₈ = 219.
Therefore, it can be said that the given sequence is in AP next three terms be 185, 202, 219.
