Answer: 54800
Step-by-step explanation: plug in 6 instead of t in both the equations. Start with the first equation
-300t+150000
-300(6)+150000= 148200
Then do the other equation
500t+200000
500(6)+200000= 20300
Subtract both
203000-148200= 54800
Solve each of these equations.

Which expression uses the associative property to make it
easier to evaluate 6(1/3•7/5)
O A. (6.1/3)7/5
O B. (6•5/7)1/3
O C. 6(7/5•1/3)
OD 3(1/6•7/5)
Answer:
A
Step-by-step explanation:
Here, we want to select which of the expressions correctly use the associative property
The associative property deals with rearrangement
So for (a + b) + c
we can have (a + c) + b
In the case of this question, the associate property is the one that makes the evaluation easier
Thus;
we need to bring 1/3 and 6 together since 3 is a factor of 6
We have;
(6•1/3)7/5
Emily plans to put her graduation money into an account and leave it there for 4 years while she goes to college. She receives $750 in graduation money that she puts into an account that earned $127.50 in interest. What was the interest rate that the bank provided
Answer:
887.40
Step-by-step explanation:
amount = principal(1i)^n
i = .0425/2 = .02125 , n = 8 , principal = 750
amount = 750(1.02125)^8 = 887.40

Answer:
C) 18 eating gummy bears
Step-by-step explanation:
The angles indicated with x-expressions are supplementary, so we have ...
(5x) +(7x+24) = 180
12x +24 = 180 . . . collect terms
x +2 = 15 . . . . . . divide by 12
x = 13 . . . . . . . . . subtract 2
Then the obtuse angle is ...
7x +24 = 7(13) +24 = 115
__
The angle marked with a y-expression is a corresponding angle to this, so has the same measure.
6y +7 = 115
6y = 108 . . . . subtract 7; next divide by 6
y = 18
Answer:
y=18
Step-by-step explanation:
5x+7x+24=180
12x+24=180
12x=156
x=13
6y+7+65=180
6y+72=180
6y=108

BRAINIEST IF RIGHT George and his dad are planning to attend the state fair. An adult ticket is $19.00. The price of an adult ticket is one third the price of a student ticket plus $15.00. Write an equation to determine how much George will pay for a student ticket.
A one thirdx + 19 = 15
B one thirdx + 15 = 19
C one thirdx − 19 = 15
D one thirdx − 15 = 19
Answer:
1/3x+15=19
Step-by-step explanation:
so B
Answer:
its b
Step-by-step explanation:
you dont know the price if the student tick so it represents x... one third of a student ticket would be one thirdx. after you do that you will have to add the extra 15 dollars to it in order to get the price if 19 dollars per adult ticket.

An equation is shown below:
4(x − 3) − 5(x + 1) = 3
Which statement shows a correct next step in solving the equation?
The equation can become 4x − 3 − 5x + 1 = 3 by applying the associative property of multiplication.
The equation can become 4x − 3 − 5x + 1 = 3 by applying the distributive property.
The equation can become 4x − 12 − 5x − 5 = 3 by applying the distributive property.
Answer:
The equation can become 4x − 12 − 5x − 5 = 3 by applying the distributive property.
Step-by-step explanation:
By applying the distributive law to this equation, we can produce the equation :
4x − 12 − 5x − 5 = 3;
The distributive property is a mathematical function in which each element in the parentheses is multiplied by the one outside of it;
4(x − 3) − 5(x + 1) = 3
In the equation;
4 distribute over the first parentheses and -5 over the second one;
So we expand;
4x - 13 - 5x -5 = 3
In distributive property, expansion simply takes place.
-3(5x+2)-(6x-5)

5+4(8n-8)=-1+6 for n
Answer:
n=1
Step-by-step explanation:
5+4(8n-8)=-1+6
5+32n-32=5
5+32n-32=5
-27+32n=5
32n=32
n=1
Answer:
n = 1
Step-by-step explanation:
5 + 4(8n - 8) = -1 + 6
First you have to distribute the 4 leaving the equation to look like this...
5 + 32n - 32 = -1 + 6
Now solve the constants (normal numbers without a variable)
-27 +32n = 5
+27 +27 You have to add 27 to BOTH sides
32n = 32
n = 1
Hope this helps and have a great day!
Two buses are traveling to a state park. One bus leaves the terminal at 4:00 pm, and travels at 40 miles per hour. The second bus
leaves the terminal at 5:00 p.m. and travels at 60 miles per hour.
At what time does the second bus catch up with the first bus?
Answer:
Step-by-step explanation:
When the second bus catches up to the first bus, this means that the distance they have travelled is equal.
So for bus 1, you know it travels at 40 miles per hour.
4pm = 0 miles
5pm = 40 miles
6 pm = 80 miles
7pm = 120 miles
For bus 2, you know it travels at 60 miles per hour
5pm = 0 miles
6pm = 60 miles
7pm = 120 miles.
So you can see that at 7pm, they will both have travelled 120 miles.

Find the range for the measure of the third side of a triangle given the measures of the other two sides are 4 and 8
Answer:
4 < x < 12
Step-by-step explanation:
Given 2 sides, then let x be the third side and
difference of 2 sides < x < sum of 2 sides , that is
8 - 4 < x < 8 + 4
4 < x < 12
how do I find the value of x so f(x)=7
Answer:
x=5
Step-by-step explanation:
Here we are given with a graph.
we have been asked to find the value of x for which
As we know that , to find the value of x for the given value of f(x), we need to look onto the vertical axis, and mark a dot on the given value now draw a line perpendicular to vertical axis so that it cut the given straight line, and where they intersect draw another line perpendicular to the horizontal axis and you will get the value where it crosses the horizontal axis.
Hence we get x=5, then f(x)=7.
Can you please help me solve this and show the solution 4y⁴+6y?
Answer:
4y^4 + 6y = 256y + 6 = 262y
Step-by-step explanation:
Remove the variables for a second and think of the problem as a normal expression; 4^4 + 6
Simplify the first term; 4^4 = 256
Now, add 6; 256 + 6 = 262
Add back in the variable; 262y
Answer:
2y(2y+3)
Step-by-step explanation:
2y(2y) +6y factor 2y out of 4y^2
2y(2y)+2y(3) factor 2y out of 6y
2y(2y + 3) factor 2y out of 2y(2y)+2y(3)
