Brad's family traveled
2
7
of the distance to his uncle’s house on Saturday. They traveled
4
5
of the remaining distance on Sunday. What fraction of the total distance to his uncle’s house was traveled on Sunday?
Answer : 4/7
Here it's given that Brad's family travelled 2/7 of the total distance to his uncle's house on Saturday . So if we assume the total distance to be 1 , then the remaining distance will be ,
[tex]\sf\longrightarrow 1 - \dfrac{2}{7}=\dfrac{7-2}{7}=\boxed{\dfrac{5}{7}}[/tex]
Again it's given that they travelled 4/5 of the remaining distance on Sunday . So , the distance travelled would be ,
[tex]\sf\longrightarrow \dfrac{4}{5}\times \dfrac{5}{7}=\boxed{\sf \dfrac{4}{7}} [/tex]
Therefore Brad's family travelled 4/7 of the total distance on Sunday .

I total of 508 tickets are sold for the school play they were either adult tickets or student tickets there were 58 more student tickets sold than adult tickets how many adult tickets were sold?
Answer:
Adult tickets sold = 225
Student tickets sold = 283
Step-by-step explanation:
Let A = total adult tickets sold
Let S = total student tickets sold
If a total of 508 tickets were sold, then A + S = 508
If there were 58 more student tickets than adult tickets sold, then
S = A + 58
Substitute S = A + 58 into A + S = 508 to find S:
A + (A + 58) = 508
2A + 58 = 508
2A = 508 - 58 = 450
A = 450 ÷ 2 = 225
If A = 225, then using S = A + 58, find S:
S = 225 + 58 = 283
Adult tickets sold = 225
Student tickets sold = 283

which of the following linear systems has a solution
(5,0)
SOMEONE PLS HELPPP
Answer:
D
Step-by-step explanation:
out of the choices
A) 2x-y=-2
3x+2y=-10
B) x+4y=3
2x+5y=3
C) 2x+3y=5
x-4y=-14
D) 3x+4y=15
x+y=5
only the system in D has a solution of x=5 and y=0
solve by substitution x+y=5 so x=5-y
plug into the other equation so 3(5-y)+4y=15
distribute 15-3y+4y=15 then minus 15 on both sides and combine like terms
so y=0 then put that value back into the other equation
so x+y=5 equals x+0=5 so x=5 this means the solution to the system of equations is the point (5,0)

One Friday night, a group of friends bought 5 containers of popcorn and 4 granola bars at the movie theatre for $42. 50. The next week, the same group of friends bought 3 containers of popcorn and 6 granola bars for $34. 50. Let p represent the cost of one container of popcorn. Let g represent the cost of one granola bar. Which system of equations will solve for p and g? 5 p 4 g = 34. 50. 3 p 6 g = 42. 50. 4 p 5 g = 34. 50. 3 p 6 g = 42. 50. 4 p 5 g = 42. 50. 6 p 3 g = 34. 50. 5 p 4 g = 42. 50. 3 p 6 g = 34. 50.
The cost of one container of popcorn and granola is $6.5 and $2.5.

To findThe equation and solution of the equation.
How to get it?Let p represent the cost of one container of popcorn.
Let g represent the cost of one granola bar.
A group of friends bought 5 containers of popcorn and 4 granola bars at the movie theatre for $42.50.
5p + 4g = 42.50 .....1
The next week, the same group of friends bought 3 containers of popcorn and 6 granola bars for $34.50.
3p + 6g = 34.50 .....2
From Equations 1 and 2, we have
p = 6.5 and g = 2.5
Thus, the cost of one container of popcorn and granola is $6.5 and $2.5.

write an algebraic expression
1. add 2 to k
2. Sam sells P rulers for Y dollars each
3. Difference between 10 and z
Answer:
1. k + 2 (or other way around, it doesn't matter)
2. PY or P×Y
3. 10 - z
Step-by-step explanation:
1. You are adding here, so you add the two terms together.
2. If we had the amount of rulers and how much they cost, we could multiply to find these. Since we don't, we just leave the two variables to be multiplied.
3. It is asking the difference between two numbers, meaning that you need to subtract. With these types of problems, you always use the first number that appears in the problem to start the expression. For instance, if it had listed z first, then you would have done z - 10.

Consider polygon JKLMNO on the coordinate grid.
Drop-down options
First one 17.07, 12.5, 25
Second 50, 30, 20
Third one 61, 47, 68.5, 37
The area of the polygon JKLMNO is 68.5 square units
The area of triangle MNOThe coordinates of the triangle are:
M = (-1, -5)
N = (-8, -6)
O = (-5, -2)
Calculate the base and the height of the triangle using:
[tex]d = \sqrt{(y_2 -y_1)^2 +(x_2 -x_1)^2[/tex]
So, we have:
[tex]ON = \sqrt{(-5+ 8)^2 +(-2 + 6)^2[/tex]
ON = 5
[tex]OM = \sqrt{(-5+ 1)^2 +(-2 + 5)^2[/tex]
OM = 5
The area is:
Area = 0.5 * ON * OM
This gives
Area = 0.5 * 5 * 5
Evaluate
Area = 12.5
Hence, the area of the triangle MNO is 12.5 square units
The perimeter of rectangle JLMOThe coordinates of the rectangle are:
J = (1, 6)
L = (5, 3)
M = (-1, -5)
O = (-5, -2)
Calculate the length and the width of the rectangle using:
[tex]d = \sqrt{(y_2 -y_1)^2 +(x_2 -x_1)^2[/tex]
So, we have:
[tex]OM = \sqrt{(-5+ 1)^2 +(-2 + 5)^2[/tex]
OM = 5
[tex]ML = \sqrt{(-1 - 5)^2 + (-5 - 3)^2[/tex]
ML = 10
The perimeter is:
Perimeter = 2 * (OM + ML)
This gives
Perimeter = 2 * (5 + 10)
Evaluate
Perimeter = 30
Hence, the perimeter of the rectangle JLMO is 30 units
The area of the polygonIn (a), we have:
The area of the triangle MNO is 12.5 square units
The area of the rectangle JKMO is:
Area = OM * ML
This gives
Area = 5 * 10 = 50
The coordinates of triangle JKL are:
J = (1, 6)
K = (5, 6)
L = (5, 3)
Calculate the base and the height of the triangle using:
[tex]d = \sqrt{(y_2 -y_1)^2 +(x_2 -x_1)^2[/tex]
So, we have:
[tex]KL = \sqrt{(5- 5)^2 +(3 - 6)^2[/tex]
KL = 3
[tex]JK = \sqrt{(1- 5)^2 +(6 - 6)^2[/tex]
JK = 4
The area of JKL is
Area = 0.5 * KL * JK
This gives
Area = 0.5 * 3 * 4
Area = 6
Add the three areas
Total area = 6 + 12.5 + 50
Evaluate
Total area = 68.5
Hence, the area of the polygon JKLMNO is 68.5 square units

Answer:
p(t) = 0 for t = 1
p(t) = 1 for t = 1/8 = 8^-1
Step-by-step explanation:
the graph you will have to do yourself.
just go there and type in
[tex] - log_{8}(x) [/tex]
well, don't type "log" in letters.
you start by typing the "-" sign, and then you need to look up the functions by clicking on the "funcs" button and look for the log functions .
pick the
[tex] log_{a}[/tex]
option. and then simply enter 8 as the first parameter in the {} brackets and x as the second in the () brackets.
and then you see.
any logarithm is 0 for x (or t) = 1.
because any a⁰ = 1.
and the logarithm gives you that exponent of the base number that leads to the given x value.
in other words : a logarithm is the inverse function of an exponential function.
the exponential function is
y = a^x
and the logarithm then determines
[tex]x = log_{a}(y) [/tex]
that is all.
and
[tex] - log_{8}(x) = 1[/tex]
means that the logarithm itself delivered -1.
and 8^-1 = 1/8
so, p(t) = 1 for t = 1/8
Hurry ASAP!!!!! I only need help with number 6 please explain how you get the answer to! The instructions for his equation is: subtract by changing the signs of the subtrahend and combining as in addition!
Answer:
-ax + 6by + 10
Step-by-step explanation:
(2ax + 3by + 5) - (3ax - 3by - 5)
Subtrahend is the value AFTER the subtraction sign. So in this example the subtrahends enclosed in the 2nd bracket are 3by and 5.
So subtracting by changing the signs of the subtrahends:
= 2ax + 3by + 5 - 3ax + 3by + 5
Collecting like terms:
= 2ax - 3ax + 3by + 3by + 5 + 5
Combining like terms:
= -ax + 6by + 10
