Answer:
Train A = 299 tons Train B = 50 tons
Step-by-step explanation:
Train A = x
Train B = y
x+y = 349
x= y +249
Plug in one equation into another
y+249+y= 349
Simplify
2y+249=349
Subtract 249 from both sides
2y=100
Divide both sides by 2
y=50
Plug it into the x equation to solve for x
x+50=349
-50 from both sides
x=299
A. No, because if you add 76.5 and 4.32, you'll get 80.82 instead of 72.18.
B. Yes, because if you add 72.18 and 4.32 you'll get 76.5
C. No, because if you substract 4.32 from 72.18, you'll get 67.86 instead of 76.5.
D. No, because if you add 76.5 and 72.18, you'll get 144.65 instead of 4.32.
Correct answer: B
All we have to do here is divide $13.50 by $0.90 to figure out how many guppies she can buy
$13.50 ÷ $0.90 = 15
Therefore, Karla can buy <u>15 guppies</u> with $13.50
