Answer:
number of pennies = 19
number of dimes = 19
number of quarters = 45 - 2 × 19 = 45 - 38 = 7
Step-by-step explanation:
The total number of coins in the box is 45 . The coins consist of pennies, dimes and quarters.
The number of pennies is equal to the number of dimes. The remaining number is the quarters. Therefore,
number of pennies = a
number of dimes = a
number of dimes = 45 - 2a
1 dime = 0.1 dollars
1 penny = 0.01 dollars
1 quarters = 0.25 dollars
Thee total cost can be expressed as follows
3.84 = a(0.01) + a(0.1) + 0.25(45 - 2a)
3.84 = 0.01a + 0.1a + 11.25 - 0.5
a
3.84 = -0.39
a + 11.25
3.84 - 11.25 = -0.39
a
-7.41 = -0.39
a
divide both sides by -0.39
a = -7.41/-0.39
a = 19
number of pennies = 19
number of dimes = 19
number of quarters = 45 - 2 × 19 = 45 - 38 = 7

Rise/run=1/2
Answer:x>3 1/6
Step-by-step explanation:
5/12-(x-3)/6 <(x-2)/3
5/12 *12-(x-3)/6*12<(x-2)/6*12
5-2(x-3)<4(x-2)
5-2x+6<4x-8
-2x+11<4x-8
-2x<4x-19
-6x<-19
-6x(-1)<-19(-1)
6x>19
x>19/6
x>3 1/6
just change all the inequality signs to a x is greater or equal to 3 1/6 and on the rest change to and < and equal sign only put > or equal sign on the last three lines
Answer:
x= -19
Step-by-step explanation:
6-2(x+5)=42
6-2x-10=42
-4-2x=42
-2x=38
x= -19
