Answer:
125.9
Step-by-step explanation:
To round 125.892 to the nearest tenth consider the hundredths’ value of 125.892, which is 9 and equal or more than 5. Therefore, the tenths value of 125.892 increases by 1 to 9.
125.892 rounded to the nearest tenth = 125.9
Answer: A and B
Explanation: A sum is an answer to an addition problem and a difference is the answer to a subtraction problem. N is the sum to the addition problem and -n is the answer to a subtraction problem.
Use ratios to solve this!
5:6 or 5/6 is the ration for Alex.
<span>Cross multiplication is used to solve this, so:
6x = 5(50) </span>
<span>6x = 250 </span>
<span>x = 250/6 </span>
<span>x = 41.67 which then rounds to
42 feet.

Answer:
B
Step-by-step explanation:
In this case, we use variables to represent the the cost of the big and the smaller boxes. Let x be the selling price of the big boxes while y be the selling price of the bigger boxes.
The total selling price of the smaller boxes is 20x. The total selling price of the bigger ones is 12y.
Now we know he is making a profit of $1,300
Hence in equation form, all the information above can be represented as:
20x + 12y = 1,300
