Answer:
b (4,-2)
Step-by-step explanation:
i dont really know how to explain it tbh
Nickels n
quarters q
I: 3.15=n*0.05+q*0.25
II: n+q=23
isolate n in II:
n+q=23
n=23-q
substitute n in I:
3.15=n*0.05+q*0.25=
3.15=(23-q)*0.05+q*0.25
3.15=(23-q)*(1/20)+(q/4)
3.15=(23/20)-q/20+(q/4)
3.15=1.15-(4*q/20)
2=q/5
10=q
insert q=10 into II:
n+q=23
n+10=23
n=13
so c) 3 more nickels than quarters
Answer:
a: 70 degrees, b: 140 degrees
Step-by-step explanation:
Each of the sets of angles must add up to 180 degrees.
180 - 110 = 70
180 - 40 = 140
