Answer:
A.D = d = m over v is the right answer.
0.1x+0.25y=29.8
How many dimes and quarters are in the container?
A.
123 dimes and 55 quarters
B.
114 dimes and 64 quarters
C.
102 dimes and 76 quarters
D.
98 dimes and 80 quarters
x+y=178
0.1x+0.25y=29.8
Solve x+y =178 for x
Add -y to both sides
x+y+-y=178+-y
x= -y+178
Substitute -y+178 for x in 0.1x+0.25y=29.8
0.1x+0.25y=29.8
0.1(-y+178)+0.25y=29.8
Simplify both sides of the equation
0.15y+17.8=29.8
Add -17.8 to both sides
0.15y+17.8+-17.8=29.8+-17.8
0.15y=12
Divide both sides by 0.15
0.15y/0.15= 12/0.15
y=80
Substitute 80 for y in x = -y+178
x= -y+178
x= -80+178
Simplify both sides of the equation
x= 98
Answer: D
x=98 and y= 80
I hope that's help !
The required percent 40% of 120% of x is equal to 0.48 times x.
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
To find 40% of 120% of x, we can first find 120% of x, and then find 40% of that result.
120% of x can be found by multiplying x by 1.2:
120% of x = 1.2 * x
Next, to find 40% of the result, we multiply by 0.4:
40% of (120% of x) = 0.4 * (1.2 * x)
So the final answer is:
40% of 120% of x = 0.4 * (1.2 * x) = 0.48x
This means that 40% of 120% of x is equal to 0.48 times x.

Answer:
48 percent
Step-by-step explanation:
The total number of flowers is 12. Then the number of tulips flower will be 4.
The utilization of two or more additional numbers that compares is known as the ratio.
Sonia was given a bouquet of flowers for valentines day.
The amount 2/3 of the flowers were roses and 1/3 of them were tulips.
If there were 8 roses. Then the total number of flowers is given as,
⇒ 8 ÷ (2/3)
⇒ 8 x (3/2)
⇒ 4 x 3
⇒ 12
Then the number of tulips is given as,
⇒ 12 - 8
⇒ 4
The total number of flowers is 12. Then the number of tulips flower will be 4.

Okay, let's see...
The problem is asking for a linear equation most likely in the form of y=mx+b
y is another way to say f(x)
m = slope
b = y intercept
Let's start with the y intercept first.
Y intercept means ' When does the line touch (intercept) the y axis.
In this case, if you look at the graph, the line touches the y axis at -1.
-1 will replaces b
To find the slope we are going to take 2 precise points from the graph.
Lets use (0,-1) and (-6,4)
To find the slope, we're going to use
4 - (-1) / -6 - 0
Solve, our slope is 5/-6
That is our m
Our final equation is
