Answer:
Solution graph is attached in the answer area.
And one possible solution is (9, 2).
9 number of dimes and 2 number of nickels.
Step-by-step explanation:
Given that:
Number of dimes = [tex]a[/tex]
Number of nickels = [tex]y[/tex]
Total number of coins are at most 12 OR total number of coins are lesser than or equal to 12.
i.e. the inequality can be written as:
[tex]a+y \leq 12[/tex] ...... (1)
One dime is worth 10 cents or $0.10.
[tex]a[/tex] number of dimes are worth $0.10[tex]a[/tex].
One nickel is worth 5 cents or $0.05.
[tex]y[/tex] number of nickels are worth $0.05[tex]y[/tex].
Second inequality can be written as:
[tex]0.10a + 0.05 \ge 0.85[/tex]
OR
[tex]2a+y\ge17[/tex] ...... (2)
[tex]a \ge 0, y \ge 0[/tex] ...... (3)
When we graphically represent the inequalities, the graph attached in the answer area represents the answer.
One solution is (9, 2).
9 number of dimes and 2 number of nickels.

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

Step-by-step explanation:
The given equation is :
[tex]\dfrac{14+10x}{12}=-3[/tex]
Cross multiply,
[tex]14+10x=-3\times 12\\\\14+10x=-36\\\\10x=-36-14\\\\10x=-50\\\\x=-5[/tex]
This equation will have only one solution.
We can check the solution as follows :
Put x = -5 in LHS of the the given equation.
[tex]\text{LHS}=\dfrac{14+10x}{12}\\\\=\dfrac{14+10(-5)}{12}\\\\=\dfrac{14-50}{12}\\\\=\dfrac{-36}{12}\\\\=-3[/tex]

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]

Answer:
c=8+3.75x, where:
c is the cost to go to the ice skating ring
x is the number of hours
Step-by-step explanation:
From the information given, the cost to go to the ice skating ring is equal to the cost to rent ice skates plus the result of multiplying the cost to skate per hour for the number of hours and the equation 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.

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;
