Lisa [10]
Here is the solution of the given problem above.
Given: Weight of single calf = weight of mother + 3.8%
           Weight of mother = 3.75 tons or 7,500 pounds
           ? = weight of the calf
First, we need to find the 3.8% of 7,500 pounds. The result is 285 pounds.

2x + y = 3<br> x = 2y - 1
Ad libitum [116K]
<span>2x+ y = 3
x = 2y - 1 
Make sure there are NO SPACES in your answer. Include a comma in your answer.
It looks like I could substitute the x=2y-1. Into 2x+y=3
2(2y-1)+y=3
4y-2+y=3
5y=5
y=1
x=2(1)-1
x=1

(1,1)
CHECK
2x+y=3
2(1)+(1)=3
2+1=3
3=3
Left hand side=Right hand side 
Check other equation 
x=2y-1
1=2(1)-1
1=1
Therefore the solution is (1,1). Since the left hand side= right hand side in each equation</span>

Semenov [28]

Answer:

1497 - 202

Step-by-step explanation:

The question is saying that the Las Vegas trip was longer so we know to put that first in the expression

we can also tell that the question is asking us for the difference (aka subtraction)  between the two trip by the key words <em>how much longer</em>

and then it tells us that we are finding the difference between Las Vegas and Cheyenne so we know to use those two numbers

that is how we come up with the expression 1497 - 202
