1. A. 10,000
Explanation: 10^4 = 10,000
2. x = -12
Explanation: see photo
D = # of dimes
n= # of nickles
d + n = 34 so d = 34 - n
.10d + .05n = 2.05
substitute d = 34 - n into .10d + .05n = 2.05
.10d + .05n = 2.05
.10( 34 - n) + .05n = 2.05
3.4 - .1n + .05n = 2.05
-.05n = -1.35
n = 27
d = 34 - n
d = 34 - 27
d = 7
answer
<span>she received 7 dimes and 27 nickels</span>
24/4.7=x x=5.1
24+x=what you want
24+5.1=29.1 there you go
-3/4 is rational because it can be written as a ratio.
