Visit $25 allergy shot $8
4a + 1v =57
-2a +1v= 9
I will multiply the second by -1 to cancel v variable (elimination method)
4a +1v =57
2a -1v = - 9
add both
6a. = 48
a= 8
4a= 32
32 + v = 57
v= 25
32+25 = 57
-16 +25=9
Answer:
B.
Step-by-step explanation:
<2 and <3 are vertically opposite angles and are also congruent. Both the angles are hence called vertical angles.

A=future amount
P=present amount
r=rate in decimal

given
P=455
r=4%=0.04
n=1
t=2
