Answer:
There are 41 dimes and 26 nickels.
Step-by-step explanation:
From the information given, you know that you have 67 coins which would be:
x+y=67
Also, you now that the value of each coin is:
dimes= $0.10
nickels=$0.05
With this you can say that the number of dimes for its value plus the number of nickels for its value is equal to $5.40:
0.10x+0.05y=5.40
You will have the following equations:
x+y=67 (1)
0.10x+0.05y=5.40 (2), where:
x are the number of dimes
y are the number of nickels
First, you can solve for x in (1):
x=67-y
Then, you can replace (3) in (2):
0.10(67-y)+0.05y=5.40
6.7-0.10y+0.05y=5.40
1.3=0.05y
y=1.3/0.05
y=26
Now, you can replace the value of y in (3) to find x:
x=67-y
x=67-26
x=41
According to this, the answer is that there are 41 dimes and 26 nickels.

What were the main important ideas in geometry that you studied in the first six weeks?
Answer:
The preceding chapter explored implications of research on learning for general issues relevant to the design of effective learning environments. We now move to a more detailed exploration of teaching and learning in three disciplines: history, mathematics, and science. We chose these three areas in order to focus on the similarities and differences of disciplines that use different methods of inquiry and analysis. A major goal of our discussion is to explore the knowledge required to teach effectively in a diversity of disciplines.

write the equation for (3,3) and (1,-3)
Answer:
y = 3x -3
Step-by-step explanation:
Find the slope first
Givens
y2 = 3
y1 = - 3
x2 = 3
x1 = 1
Equation
m= (y2 - y1)/(x2 - x1)
Solution
m = (3 - - 3) / (3 - 1)
m = (3 + 3) / 2
m = 3
Find the y intercept next
Use either point to find the y intercept
y = 3x + b
x = 3
y = 3
y = 3*3 + b
3 = 6 + b
-3 = b
Answer
y = 3x - 3

HELPPPPPP I HAVE BEEN TRYING FOR AGES
Answer:
1.88 to 2 decimal places
Step-by-step explanation:
First, I plugged in 1.8 and 1.9:
1.8^3-3*1.8=0.432
1.9^3-3*1.9=1.159
Then, I plugged in 1.85:
1.85^3-3*1.85=0.78
Next, I plugged in 1.87 to get the answer closer to 1:
1.87^3-3*1.87=0.93
Finally, I plugged in 1.88 to get even closer to 1:
1.88^3-3*1.88=1.00
Hope this helps!
Answer:
Step-by-step explanation:
1.8=-0.568 is too small
1.9=0.159 is too big
1.87=-0.70797 is too small
1.88=0.004672 is too big
Next, I plugged in 1.87 to get the answer closer to 1:
1.87^3-3*1.87=0.93
Finally, I plugged in 1.88 to get even closer to 1:
1.88^3-3*1.88=1.00
1.875=-0.033203125 is too small
so it should be 1.88 to 2 decimal places

Select the correct answer. Fredrick manages a band and sings lead vocals. The band charges $700 per concert. Fredrick receives $175 of that money, and he shares the rest equally among the other 5 members of the band. How much money does each of the 5 band members receive per concert? A. $105 B. $112 C. $175 D. $525
Answer:
A. $105
Step-by-step explanation:
Given
total charge= $700 per concert
solution
If Fredrick receives $175 of that money, the balance will be
$700-$175= $525
The balance will be shared by the 5 members
Hence each of them will take
525/5=$105
Answer:
$105

Step-by-step explanation:
SF of KP to KN = 4
If LM = 32, then we would have to divide 32 by 4 in order to get the missing length of KL.

Length of KL = 8
Length of LM = 32
Length of KM = 32 + 8 = 40

Richard has 15 apples. He gave Pam 5/2 of them to bake a pie. How many apples did he give to Pam?
Answer:
2.5 or 2 1/2 apples.
Step-by-step explanation:
5/2 simplified will be 2.5 or 2 1/2.
If you look into it further, because Richard had 15 apples, you subtract 2 1/2 apples he gave Pam which would leave him with 12.5 or 12 1/2. But really the answer is two and a half apples.
4x?x2=48
by the way i'm unsmart I just wanted to show my little brother how brainly works
Answer:
6
Step-by-step explanation:
So I assume it's 4 × x × 2 = 48
First multiply the like terms (4 x 2) and you'll get 8.
8 × x = 48
Then you 8 by the x and get 8x
8x = 48.
Lastly you'll just divide 48 by 8 and get 6.
Hope your brother understands how this works now! (It's basically legal cheating)
Answer:
6
