0.21 would be rational,because it is a terminating decimal,which means that it has an ending point and can be converted into a fraction.ur welcome
Let the fare of adults be 'x' and that of children be 'y'
Equation Formation.
3 x + 4 y = 87................ equation (i)
2 x + 3 y = 62................ equation (ii)
3 x +4 y = 87 ..............×2
2 x +3 y = 62...............×3
6 x + 8 y = 174
6 x + 9 y = 186
y = 12
2 x = 62 - 3 y
2 x = 62 - 36
2 x = 26
x =13
Answer = adults ⇒ $13
children ⇒$ 12
Hi how are you I’m good math is hard
Hey I'm on this question on my test too. I think the answer is:
First Box: "
Reflection across the x-axis"
Last Box: "
Translation 1 unit down"
What the sentence should look like = "<span>
△RST</span><span>
to </span><span>
△<span>
R′</span><span>
S′</span><span>
T′</span></span><span>
is a reflection across the x-axis followed by a translation 1 unit down."
I hope this helps!</span>

Answer:
D. 36 units
Step-by-step explanation:
Using the distance formula, we find the length of AB to be ...
d = √((x2 -x1)² +(y2 -y1)²)
d = √((7-(-2))² +(-3-9)²) = √(81 +144) = √225 = 15
The line BC is horizontal, so its length is the difference of the x-coordinates:
BC = 7 -(-2) = 9
The line AC is vertical, so its length is the difference of the y-coordinates:
AC = 9 -(-3) = 12
The sum of the lengths of the sides of the triangle is ...
P = 15 + 9 + 12 = 36
The perimeter is 36 units.
