Answer:
slope is -55 balance decreases by $55 each month
Step-by-step explanation:
solve for slope using slope formula:
(620-895)/(6-1) = -275/5 = -55
decreases by $55 since that's the slope

Answer: b. Side BC and Side KL
Step-by-step explanation:
Only these two lines are in the same positions.
Given/equations formed from text:
I: l=w+3
II: A=l*w
III: new area B=(l-2)*w
IV: B=A-30
substitute l in II with I to remove l:
II': A=l*w=
(w+3)*w=
w^2+3w
substitute l in III with I to remove l:
III': B=(l-2)*w=
(w+3-2)*w=
(w+1)*w=
w^2+w
substitute A and B from II' and III' into IV:
B=A-30
w^2+w=w^2+3w-30
30=2w
w=15
insert w=15 into I:
l=15+3=18
->
A) dimensions of full size rectangle are width 15 and length 18
dimensions of reduced size rectangle are width 15 and length 16
B) full size: 15*18=10*18+5*18=180+90=270cm^2
reduced size: 15*16=10*16+5*16=160+80=240cm^2
Let
x---------> the total number of coins
we know that
512 cents-------> is equal to $5.12
1 penny is equal to $0.01
1 nickel is equal to 5 penny--------> $0.05
1 dime is equal to 2 nickel--------> $0.10
![\frac{x}{3}*[0.01+0.05+0.1]=5.12 \\\\x*[0.16]=15.36 \\\\ x=\frac{15.36}{0.16} \\\\x= 96\ coins](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B3%7D%2A%5B0.01%2B0.05%2B0.1%5D%3D5.12%20%5C%5C%5C%5Cx%2A%5B0.16%5D%3D15.36%20%5C%5C%5C%5C%20x%3D%5Cfrac%7B15.36%7D%7B0.16%7D%20%5C%5C%5C%5Cx%3D%2096%5C%20coins)
the total number of coins are 96
Divide 96 by 3 to obtain the number of coins of each type
therefore
<u>the answer is</u>
the number of penny coins are 
the number of nickel coins are
the number of dimes coins are
