Martin has a total of 19 nickels (50.05) and dimes ($0.10) worth $1.65. How many of each type of coin does he have?
can put your work too
Answer: 19nickels and 7dimes.
Ps i really don’t know where the 50.05 came from if it is suppose to be there then I really don’t know how to solve this.
Step-by-step explanation:
Ok so if you know that there are 19nickels, let n=number of nickels.
The number of total coins subtracted by number of nickels will give you number of dimes.
165-number of nickels=number of dimes
Value of dimes=10(number of dimes) or total value of dimes/individual value (10cent)
Then you can substitute total as $1.65 and get the value of nickels by multiplying by 5cent ( my teacher taught me using whole numbers to make it easier so I turned $1.65 to 165 cent). Since the value of the dimes is the value of nickels subtracted from the total, I can subtract 95 from 165 and divide the difference by 10, to get the number of dimes.
5(n)=5(19)=95
(165-95)/10=number of dimes
70/10=7dimes
You can check by multiplying 7x10 and 5x15 again and adding them together to see if they equal 165 cent.

Answer:
5. 216, 1416
6. 448.5 g
Step-by-step explanation:
5.
Price of 1 item: 1200
GST = 18%
18% of 1200 =
= 0.18 * 1200
= 216
Amount of tax: 216
Total price = original price + GST
Total price = 1200 + 216 = 1416
6.
Weight of 1 item: 17 1/4 g
Weight of 26 items = 26 * 17 1/4 g
26 * 17.25 g = 448.5 g
Tara and Ashley spent the same amount at the grocery store. Tara bought 5 pounds of apples. Ashley bought 3 pounds of apples and $5 worth other groceries. How much does one pound of apples cost?
Answer:
one pound of apple cost $2.5
Step-by-step explanation:
Let the amount they both spent at the grocery store be y and x be the price of apples per pound.
Since Tara bought 5 pounds of apples, 5x = y (1) and Ashley bought 3 pounds of apples and $5 worth other groceries, 3x + 5 = y (2).
Equating both expressions, 5x = 3x + 5
collecting like terms,
5x - 3x = 5
2x = 5
dividing both sides by 2, we have
x = 5/2
x = 2.5
So one pound of apple cost $2.5

Please help! I will give brainliest to person who answers correctly :) Which ordered pair is the solution to the system of equations? −5x−3y=12 y=x−12 (−6, 6) (0, −4) (1, −11) (3, −9)
Answer:
(3,-9)
Step-by-step explanation:
The given equations are :
−5x−3y=12 (1)
y=x−12 ....(2)
Put the value of y from equation (2) in equation (1)
−5x−3(x-12)=12
-5x-3x+36 = 12
Taking like terms together
-5x-3x = 12-36
-8x = -24
x = 3
Put the value of x in equation (2)
y=3−12
y = -9
Hence, the solution of the above equations is x = 3 and y = -9 or (3,-9).
Five times a number decreased by six is 29
Answer:
Let x be the number
"five times a number"
5x
"six less than five times a number"
5x-6
"is at least 29" >29 (greater than or equal too)
5x - 6 > 29
5x > 35 (add +6 to both sides retains the dense if the inequality)
x>7 (divide both sides by +7 retains the sense of Inequailty)
Check:
Is 5(7) - 6 > 29?
35 - 6 > 29 ?
29 > 29? yes, they are equal.
Try 50:
Is 5(50) - 6 > 29 ?
250 - 6 > 29?
244 > 29 ? yes
Answer:
5x - 6 = 29
Solve for x and y if this is what’s given to you
Answer:
x=7; y=21
Step-by-step explanation:
These angles are congruent so:
7y-3=2x+4
We need to find x, and AB and DC are congruent, so:
3x+3=6x-18
Add 18 to both sides:
3x+21=6x
Subtract 3x from both sides:
3x=21
Divide by 3:
x=7
Substitute:
7y-3=2(7)+4
Simplify Like-Terms:
7y-3=18
Add 3 to both sides:
7y=21
Divide both sides by 7:
y=21

Help me find the values of k and p please
Answer:
B
Step-by-step explanation:
The lines marked with ||| are equal. That means that 2P + 7 equals 17
2P + 7 = 17 Subtract 7 from both sides.
2P + 7 - 7 = 17 - 7 Combine
2P = 10 Divide by 2
P = 5
3k - 5 and 28 are marked with one | That means that they are equal
3k - 5 = 28
3k = 28 + 5
3k = 33
k = 33/3
k = 11
The answer is B
Can somebody please solve this problem. I need help
Answer:
X=4
Step-by-step explanation:
4(x+12) = 19x-12
4x+48= 19x-12
sub 4x from both sides
48= 15x-12
add 12 to both sides
60=15x
divide 15 from both sides
and 60/15 =4
Answer:
[tex]4(x + 12) = 19x - 12 \\ 4x + 48 = 19x - 12 \\ 4x - 19x = - 12 - 48 \\ - 15x = - 60 \\ x = \frac{60}{15} \\ x = 4[/tex]
