Step-by-step explanation:
if you're looking for x
x=180-42-51= 87°
and if you're looking for D
D= 180-42= 138°
Answer:
d)X=4 or x=-2
Step-by-step explanation:
X²-2x=8
X²-2x-8=0
(x-4)(x+2)=0
X-4=0 or x+2=0
X=4 or x=-2
C=300+1200x-100x. Find x if the total cost is 3,000
3,000 = 300 + 1200x -100x
3000 = 300 + 1100x
2700 = 1100x
2700÷1100=x
x=27/11
x = 2 5/11
Round to 3
Answer:
1 3/4 simplified or 1 12/16 not simplified
Answer:
B.
y = $0.79x + $46.88
