Answer:
A.) 15.60=11.40+10x
Step-by-step explanation:
okay we know kathy spent 15.60 in total at the post office
so we know 15.60 will be after the equal sign.
she paid 11.40 only on the package
and rest of money was on stamps.
15.60-11.40= 4.20
so she used 4 dollars and 20 cents for stamps if she bought 10 we need to divied 4.20/10=0.42
0.42 cents for each stamps so we need a equation that will give us this answer.
Me i go thru each one and solve for x
lucky for me i just need to solve one
because equation A solves it correctly.
15.60=11.40+10x
subtract 11.40 on both sides
15.60-11.40
4.20=10x
now we divide 10 on each side
4.20/10=0.42
x=0.42

Answer:
Option C. is correct
Step-by-step explanation:
In the triangle ABC, vertices are A(12, 8), B(4, 8) and C(4, 14)
AB =
BC =
AC =
In triangle XYZ vertices are X(6,6), Y(4,12) and Z(10, 14)
XY =
YZ =
XZ =
In triangle MNO, vertices are M(4, 16), N(4, 8) and O(-2, 8)
MN =
MO =
NO =
In triangle JKL, vertices are J(14, -2), K(12,2) and L(20, 4)
JK =
KL =
JL =
Now we compare the sides for the congruence
Since AB = MN = 8
BC = NO = 6
AC = OM = 10
So ΔABC ≅ Δ MNO
Option C. is correct

Radius of circle= 4
a) circle circumference=2(pi)r
circumference=2(pi)4=25.13
P=2W+2L
p=2(5)+2(10)
P=30
b) area of circle=pi(r^2)=pi(16)=50.27
