Step-by-step explanation:
total of 342 tickets were sold for school play. They were either adults tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold. How many adult tickets were sold?
Answer:
684 I think ?!
Step-by-step explanation:
Answer: 114 adult tickets were sold.
Step-by-step explanation:
Let student tickets be represented as 2t (since twice the amount of student tickets were sold)
and let t represent the amount of adult tickets.
Solve for t (number of tickets)
342= 2t + t. Combine like terms.
342= 3t. Divide both sides by 3.
114=t
114 adult tickets were sold.
Substitute 114 for t to find student tickets.
2(114)= 228 student tickets were sold.

[tex]15\ \textless \ -5x[/tex]
Answer:
x < -3
Step-by-step explanation:
Switch sides
-5x > 15
Multiply both sides by: -1 (reverse the inequality)
(-5x)(-1) < 15 (-1)
Simplify
5x < -15
Divide both sides by 5
5x/5 < -15/5
Simplify: 5x/5
Divide the numbers: 5/5 = 1
= x
Simplify: -15/5
Apply the fraction rule: -a/b = a/b
= -15/5
Divide the numbers: 15/5 = 3
= -3
x < -3

Answer:
[tex]\Huge\boxed{x<-\frac{1}{4}}[/tex]
Step-by-step explanation:
Hello there!
The first thing we want to do is find the least common denominator which would be 20
so we multiply the denominator and numerator of the fractions on the left side by 4
3x4=12
5x4=20 -12/20x
1x4=4
5x4=20 so now we would have
[tex]-\frac{12}{20}x+\frac{4}{20} >\frac{7}{20}[/tex]
once again we want to isolate the variable using inverse operations
to get rid of the 4/20 we subtract each side by 4/20
[tex]\frac{7}{20} -\frac{4}{20} =\frac{3}{20}[/tex]
now we have
[tex]-\frac{12}{20} x>\frac{3}{10}[/tex]
now we want to get rid of the -12/20
to do so we divide each side by -12/20 (or -.6 as a decimal to make it easier)
[tex]\frac{3/20}{-.25}=-\frac{1}{4}[/tex]
REMEMBER flip the equality sign
we're left with
[tex]x<-\frac{1}{4}[/tex]

Consider the following system of equations.
a+b-4c=1
a+4b+c=12
a-3b-2c=-5
Show that (3,2,1) is a solution to the system
Answer:
Step-by-step explanation:
a+b-4c-a-4b-c=1-12, -3b-5c=-11
a+4b+c-a+3b+2c=12+5, 7b+3c=17
3(-3b-5c)+5(7b+3c)=3(-11)+5(17)
-9b-15c+35b+15c=-33+85
26b=52
b=2, making 7b+3c=17 become
14+3c=17
3c=3
c=1, making a+b-4c=1 become
a+2-4(1)=1
a-2=1
a=3
(a,b,c)=(3,2,1)
You are dealt one card from a standard 52-card deck. Find the probability of being dealt an ace or a 6.
Answer:
2/13
Step-by-step explanation:
Since there's 4 of each card in the deck this means that there're 4 sixes and 4 aces, so 8 cards in a 52 card deck gives the problem 8/52 which equals 2/13
the distance between the points a(-1 3) and b(2 -1) is:
Answer:
Point x equals 3 and y equals -4 so the answer is (3,-4)
Step-by-step explanation:
The distance between the points a(-1 3) and b(2 -1) is 5.
What is the distance formula?The Distance Formula squares the differences between the two x coordinates and two y coordinates, then adds those squares, and finally takes their square root to get the total distance along the diagonal line:
The distance between the points a(-1 3) and b(2 -1).
The distance beween two points is given by;
[tex]\rm Distance=\sqrt{(x_2-x_2)^2+(y_2-y_1)^2}[/tex]
Substitute all the values in the formula;
[tex]\rm Distance=\sqrt{(x_2-x_2)^2+(y_2-y_1)^2}\\\\\rm Distance=\sqrt{(2-(-1))^2+(-1-3)^2}\\\\\rm Distance=\sqrt{(3)^2+(4)^2}\\\\\rm Distance=\sqrt{9+16}\\\\\rm Distance=\sqrt{25}\\\\Distance =5[/tex]
Hence, the distance between the points a(-1 3) and b(2 -1) is 5.

2. Tara has 4/5 of a bag of dog food. If her dogs eat 1/10 of the bag each week, how many weeks will the food last?
Answer:
7/10 bags left but 7 weeks left
Step-by-step explanation:
because if you convert 4/5 to 10ts it would be 8/10
so you would have to subtract i am guessing 8/10-1/10 and get 7/10ths
and sicince she gives her dog 1/10 a week then she would have 7 weeks left

Answer:
6/(2+k)
Step-by-step explanation:
The change of base formula is ...
[tex]\log_a(b)=\dfrac{\log(b)}{\log(a)}[/tex]
Using this, we can take the logarithm base 2 in the change of base formula for the given expression.
[tex]\log_{20}(64)=\dfrac{\log_2(64)}{\log_2(20)}=\dfrac{\log_2(2^6)}{\log_2(2^2\cdot5)}\\\\=\dfrac{6}{\log_2(2^2)+\log_2(5)}=\boxed{\dfrac{6}{2+k}}[/tex]

In addition to the change of base formula, the usual rules of logarithms apply.

What is triangle congruency?There are ways to prove that two triangles are congruent.
- Side-Side-Side (SSS) Congruence.
The three sides of one triangle are equal to the corresponding three sides of another triangle.
- Side-Angle-Side (SAS) Congruence.
The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.
- Angle-Side-Angle (ASA) Congruence.
The two angles and the included side of one triangle are equal to the corresponding two angles and included side of another triangle.
- Angle-Angle-Side (AAS) Congruence.
We have,
Side-Angle-Side (SAS) Congruence.
The two sides and the included angle of one triangle are equal to the corresponding two sides and included angle of another triangle.
So,
The ΔABC, ΔFGE, and ΔPQR are congruent since there is a congruent angle between the corresponding equal sides in all three triangles.
Thus,
The ΔABC, ΔFGE, and ΔPQR are congruent by SAS.

Find the value of x in (5,x),(x,14) so that the line line containing them is 7/2.
Answer:
7
Step-by-step explanation:
If what you meant by 7/2 was the slope of the line then we can plug in the two points into the slope formula to get our line:
14-x/x-5 = 7/2
This means that 14 - x = 7 and x - 5 = 2. We can see that 14 -7 = 7 and 7 - 5 = 2,
meaning that the value of x should be 7.

Step 1: Define Systems
x - 2y = 12
5x + 3y = -44
Step 2: Rewrite Systems
x - 2y = 12
[Multiplication Property of Equality] Multiply everything by -5: -5x + 10y = -60Step 3: Redefine Systems
-5x + 10y = -60
5x + 3y = -44
Step 4: Solve for y

Combine 2 equations: 13y = -104[Division Property of Equality] Divide 13 on both sides: y = -8Step 5: Solve for x

2. (5x - 13) (3x + 17)
Answer:
Q1. x= 18, y=59
Q2. m∠J= 56°
Step-by-step explanation:
Q1. (3x +5)°= y° (base ∠s of isos. △)
y= 3x +5 -----(1)
(3x +5)° +y° +(4x -10)°= 180° (∠ sum of △)
3x +5 +y +4x -10= 180
7x +y -5= 180
7x +y= 180 +5
7x +y= 185 -----(2)
Substitute (1) into (2):
7x +3x +5= 185
10x= 185 -5
10x= 180
x= 180 ÷10
x= 18
Substitute x= 18 into (1):
y= 3(18) +5
y= 59
Q2. (5x -13)°= (3x +17)° (base ∠s of isos. △)
5x -13= 3x +17
5x -3x= 17 +13
2x= 30
x= 30 ÷2
x= 15
∠LKJ
= 3(15) +17
= 62°
∠KLJ= 62° (base ∠s of isos. △)
m∠J
= 180° -62° -62° (∠ sum of △JKL)
= 56°
