Answer:
Step-by-step explanation:
No.
0.3^4 or 0.3x0.3x0.3x0.3= 0.0081
0.9^2 or 0.9x0.9=0.81
These are not equivalent.
Answer:
-x +7
Step-by-step explanation:
Combine like terms.
Rewrite as 2x + (-3x) + 6 + 1
Combining your "x" terms gives you 2x + (-3x), or 2x - 3x = -1x or -x
Combining your integer terms gives you 6 + 1 = 7.
Recombining them gives you -x + 7.
Number of pennies:P
Number of nickels:N
Number of dollar bills:D
P=N+12
N=D+5
1P+5N+100D=996
^given
Therefore
P=(D+5)+12
P=D+17
Plug back into main equation
(D+17)+5(D+5)+100D=996
Combine like terms
106D+42=996
106D=954
D=954/106=9
9 Dollar bills
N=D+5
N=(9)+5=14
14 Nickels
P=N+12
P=(14)+12=26
26 Pennies
26*1+14*5+9*100=996
Final answer:
9 Dollars
14 Nickels
26 Pennies
Answer:
5
Step-by-step explanation:
6a = (a*-3) + 45
then:
6a = -3a + 45
6a + 3a = 45
9a = 45
a = 45/9
a = 5
Check:
6*5 = (5*-3) + 45
30 = -15 + 45
