Dear Dollster444, the sum of angles Y and Z is bigger than Y.
Answer:
x=3/4,y=5/2
Step-by-step explanation:
y=-x^2+4,y=2x+1
substitute y=-x^2+4 as y for y=2x+1
2x+1=-x^2+4, x=3/4(isolate "x")
x=3/4
substitute x=3/4 for 2x+1=-x^2+4
y=2*3/4+1
y=5/2
x=3/4, y=5/2
hope this helps!
Answer:
23/50
Step-by-step explanation:
27 + 23 = 50 (Implying that 50 is the total amount of tickets).
23 of them were sold to adults, so basically 23/50.
Remember a ratio can be written in 3 forms, so it can be either of these:
23:50
23/50
23 to 50
The best estimate would be D: 331 km
