The sum of the inside angles of a triangle, always sum up to 180 degrees. Using this information, we can create the following equation for this problem:
Adding up all terms with 'x' and adding the other together, we have the following equation:
Solving this last equation for 'x', we have the following:
Then, the final answer for the 'x' value is twelve!
Answer:
$16
Step-by-step explanation:
He had $16 so he had spent all of it due to the question asked.
In order to solve this we need to make on part of both statements equal.
Since 12 is divisible by 6 lets do that.
Multiply everything in the second package by 2.
It then becomes 6 pairs for $12.
So now have have 6 or 8 pairs for $12.
You are getting a different amount for the same price therefore they are not proportional.
2.5 pounds of grain cost ======= $1.75
∴ 5.3 pounds of grain will cost ===== (5.3×1.75)/2.5 = $3.71
Step-by-step explanation:
3y + x = 12
When y = 3, we have 3(3) + x = 12.
=> 9 + x = 12, x = 3.
