A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 18% are pennies and 36% are dimes. There are 2 more nickels than pennies. How much money does the bag contain?
Answer: $5.44
Step-by-step explanation:
18% of 50= 9 pennies
36% of 50= 18 dimes
9 + 2= 11 nickels
9+18+11= 38 pennies, nickels and dimes.
50 (total amount of coins) - 38 (pennies nickels and dimes)= 12 quarters.
9 pennies= 9 cents
18 dimes= 180 cents
11 nickels= 55 cents
12 quarters= 300 cents
9 + 180 + 55 + 300= 544 cents= $5.44
Answer:
$5.44
The bag contains $5.44.
Step-by-step explanation:
Pennies:
50(18/100)= 9 pennies
Dimes:
50(36/100)= 18 dimes
Nickels:
2 more nickels than pennies
9+2= 11
Quarters:
9+18+11= 38
50-38= 12 quarters
1 penny = 0.01 dollar
9x0.01= 0.09
1 dime = 0.10 dollar
18x0.10= 1.80
1 nickel = 0.05 dollar
11x0.05= 0.55
1 quarter = 0.25 dollar
12x0.25= 3
0.09+1.80+0.55+3= $5.44

Plz help with this question
since both equations are equal to y...
y = 2x + 10
y = -4x - 2
2x + 10 = y = -4x - 2
2x + 10 = -4x - 2
2x + (4x) = -2 + (-10)
6x = -12
x = -2
______________________________
plug in x = -2 into one of those equations: I will use y = 2x + 10
y = 2(-2) + 10
y = -4 + 10
y = 6
______________________________
okay, so I rechecked my answers several times, and I still got (-2,6)
That MC question has an error since none of the answer choices fit.
Inform your teacher about this.
(I'd say choose that (-3,4) since it works only for one equation y = 2x +10 .... maybe your teacher was supposed to use the other equation instead of y = -4x - 2)

Step-by-step explanation:
Choose two points from the graph (0,0) and (1,-6)
Average Rate of Change= (y2-y1)/(x2-x1)
(-6-0)/(1-0)=-6/1=-6
y=-6x+b
0=-6(0)+b
0=0+b
0=b
Y=-6x+0
