Answer: The answer is 27 good luck
Step-by-step explanation:
Answer:
x = number of nickels = 127
y = number of dimes = 156
z = number of quarters = 78
Step-by-step explanation:
Let
x = number of nickels
y = number of dimes
z = number of quarters
Total worth of the coins = $41.45
Total number of coins = 361
x + y + z = 361 (1)
dime = $0.1,
nickel = $0.05
quarter = $0.25
0.05x + 0.1y + 0.25z = 41.45 (2)
twice as many dimes as quarters.
y = 2z
Substitute y = 2z into (1) and (2)
x + 2z + z = 361
0.05x + 0.1(2z) + 0.25z = 41.45
x + 3z = 361
0.05x + 0.2z + 0.25z = 41.45
x + 3z = 361 (3)
0.05x + 0.45z = 41.45 (4)
Multiply (4) by 20
x + 3z = 361 (3)
x + 9z = 829 (5)
Subtract (3) from (5)
9z - 3z = 829 - 361
6z = 468
Divide both sides by 6
z = 468 / 6
= 78
z= 78
Recall,
y = 2z
= 2(78)
= 156
y = 156
Substitute the value of y and z into
x + y + z = 361
x + 156 + 78 = 361
x + 234 = 361
x = 361 - 234
= 127
x= 127
x = number of nickels = 127
y = number of dimes = 156
z = number of quarters = 78
Answer:
5 km
Step-by-step explanation:
the scans means that any distance on the map is 50000 times larger in real life.
so, 10 cm on the map is
10×50000 = 500000 cm in real life.
now, we know that 100cm = 1 m
so, it is 500000/100 = 5000 m in real life.
and there are 1000 m in 1 km.
so, it is 5000/1000 = 5 km in real life
Answer:

Harley, Olga, Kayla, Karla
Step-by-step explanation:
Change each number into a decimal, then compare them.
Karla saved 2/3 = 0.666...
Olga saved 25% = 0.25
Harley saved 1/8 = 0.125
Kayla saved 0.40 = 0.4
From least to greatest:
