Answer:
0.05n + 0.10 d =24.40
Step-by-step explanation:
Nickel is worth 0.05 of a dollar(1)
The system of equations below would be the best to use to find the number of nickels and dimes Anthony had at the end of the first week is:
n + d = 368
0.05n + 0.10d = 24.40
The number of nickels and dimes Anthony saved at the end of the first week can be determined using two equations. This is known as simultaneous equations.
The total number of nickels and dimes in the jar is 368. This can be represented with the equation:
nickels + dimes = 368
n + d = 368. This would be the first equation.
A nickel is equal to 0.05 of a dollar and a dime is equal to 0.1 of a dollar. The total sum of money in the jar is $24.40. This means that the value of dimes and nickels in the jar is $24.40. This can be represented with the equation: 0.05n + 0.10d = 24.40. This is the second equation.

Stewie wants to rent a moving truck.Suppose company a charges a rate of $40 per day band company b charges a $60 fee plus has a rate of $20 per day.For what number of days is the cost same?
Answer:
The indifference point is 3 days.
Step-by-step explanation:
Company A:
Total cost= 40*x
Company B:
Total cost= 60 + 20*x
x= number of days
To calculate the indifference point, we need to equal both formulas. and isolate x:
40x = 60 + 20x
20x= 60
x= 60/20
x= 3
The indifference point is 3 days.
Prove:
Company A:
Total cost= 40*3= $120
Company B:
Total cost= 60 + 20*3= $120

Answer: A
Step-by-step explanation: I did the assesment
Khalid and Jesse took different overnight trains. The graph shows the relationship between the total distance Khalid traveled and the time in hours. The distance Jesse traveled after x hours is given by the equation y = 150x. Who, if anyone, traveled at a faster speed? Use the drop-down menus to explain your answer.
Khalid’s rate is ____ miles per hour. Jesse’s rate is ____ miles per hour. So, ____ train traveled at a faster speed.
Answer:
Khalid’s rate is 140 mi/h. Jesse’s rate is 150 miles per hour
So, Jesse’s train traveled at a faster speed
Step-by-step explanation:
Here, we want to compare speeds
For Jesse’s train, the speed is 150 mi/h
we got this from the fact that the equation of a straight line is represented as;
y = mx + b
where m which is the slope represents the rate of change
m here is 150
For Khalid’s;
we can get his own rate from the graph
This can be obtained using the slope
We can simply have this as ;
m = (y2-y1)/(x2-x1)
Let us have two points
(4,560) and (0,0)
Thus;
m = 560/4 = 140 mi/h
Hence;
Khalid’s rate is 140 mi/h. Jesse’s rate is 150 miles per hour
So, Jesse’s train traveled at a faster speed

8x - 3 = 16x - 33 find x
Answer:
The answer is x=15/4
Step-by-step explanation:
8x - 3 = 16x - 33
8x−3−16x=16x−33−16x
−8x−3=−33
−8x−3+3=−33+3
−8x=−30
−8x/-8=−30/-8
x=15/4
The value of the x for the equation 8x-3=16x-33 is 3.75.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
8x-3=16x-33
Simplify the equation,
⇒33-3 = 16x-8x
⇒30 = 8x
⇒8x = 30
⇒x = 3.75
The value of x is 3.75.

Please can I have an explanation, I am terrible at these kinds of questions! Q- A bag contains red, yellow and blue beads. The ratio of red beads to yellow beads is 2:3 The ratio of yellow beads to blue beads is 5:4 Work out what fraction of the beads are red.
Answer:
[tex]Red = \frac{10}{37}[/tex]
Step-by-step explanation:
Given
[tex]Red:Yellow = 2 : 3[/tex]
[tex]Yellow: Blue = 5 : 4[/tex]
Required
Determine the fraction of Red
First, we need to link the given ratios.
Since yellow is present in both ratios, we start by making the ratio of yellow equal in both ratios
Multiply this ratio by 5
[tex]Red:Yellow = 2 : 3[/tex]
This becomes
[tex]Red:Yellow = 10 :15[/tex]
Similarly, multiply this ratio by 3
[tex]Yellow: Blue = 5 : 4[/tex]
This becomes
[tex]Yellow:Blue =15:12[/tex]
At this point, we have:
[tex]Red:Yellow = 10 :15[/tex] and [tex]Yellow:Blue =15:12[/tex]
Combine
[tex]Red:Yellow:Blue = 10:15:12[/tex]
The fraction is then calculated as:
[tex]Red = \frac{Red}{Red +Yellow + Blue}[/tex]
This gives
[tex]Red = \frac{10}{10+15+12}[/tex]
[tex]Red = \frac{10}{37}[/tex]

Are you study of a population of 1200 frogs you feel that sold out of every 180 frogs in the population has spots on the back based on the results of the other study how many frogs in the population do not have spots in the back
Answer: 1,120 frogs
Step-by-step explanation:
If 12 out of every 180 frogs in the population have spots on their backs, the number that do not are;
= 180 - 12
= 168 frogs
168 frogs out of every 180 do not have spots. Out of 1,200 that would be;

2(3v-5)=2(v-11)-4 can someone help me out ?
Answer:
v = -4
Step-by-step explanation:
2(3v - 5) = 2(v - 11) - 4
6v - 10 = 2v - 22 - 4
+10 +10
6v = 2v -12 - 4
-2v -2v
4v = -16
divide both sides by 4
v = -4
Hope this helps!!
The value of v = - 4.
We have the following equation -
2(3v - 5) = 2(v - 11) - 4
We have to find out the value of the variable v.
What is the solution of a equation in one variable?The solution of an equation is the value of variable for which the left hand side is equal to right hand side.
We have the following equation -
2(3v - 5) = 2(v - 11) - 4
2 x 3v - 2 x 5 = 2v - 2 x 11 - 4
6v - 10 = 2v - 22 - 4
6v - 10 = 2v - 26
6v - 2v = - 26 + 10
4v = -16
v = - 4
Hence, the value of v = - 4.
