Can you check my problems?
1. Write the phrase shown using only numbers and symbols. The sum of thirty-six plus twelve divided by 4
= (36+12)/4
2. Evalute the following expression
36 + 12 / 4
= 36 + 3 = 39
3. Write an expression for the phrase below: double five and then add 26
= (5+5) + 26
4. Maria correctly solved 20*300=6000. How can she use this information to help her solve 21*300? Explain using words, pictures, or numbers.
= She can multiply 21 by 3 to get a product of 63. SInce using multiple of a 100, she can add 2 zeros to get final answer of 6300.
5. Evaluate the following: 10+[5(23-18)]/5
= 10 + [5(5)]/5
= 10 + 25 / 5
= 10 + 5
=15
6. A t-shirt printing company can pack 24 shirts per box for shipping. If they need to ship 492 shirts to Lakeside elementary School, how many boxes will it take to ship all 492 shirts?
=492/24
= 20.5 = 21 boxes
Good job! I agree with all of your answers.
One comment is that for number 3 it might be better to do (5*2)+26. But other than that great job!
Question no 4.
20 ×300=6000
21×300=6300
Basically,21×3=63.The two zeros in which we omitted earlier will now be added to give you 6300.I hope you understand me better.Thanks for paying attention
Thanks Gracie and Kaka!
21*300
= 20*300 + 1*300 = 6000 + 300 :)
It seems like you have correctly solved the problems. Great job! Here's a breakdown of each solution:
1. To write the phrase "The sum of thirty-six plus twelve divided by 4" using numbers and symbols, you can express it as (36+12)/4.
2. To evaluate the expression 36 + 12 / 4, you need to follow the order of operations. First, divide 12 by 4, which equals 3. Then, add 36 and 3, resulting in 39.
3. To write an expression for the phrase "double five and then add 26," you can represent it as (5+5) + 26.
4. To use the information of correctly solving 20*300=6000 to solve 21*300, Maria can see that multiplying 21 by 3 gives a product of 63. Since she is using multiples of 100, she can add 2 zeros to the end, resulting in a final answer of 6300.
5. To evaluate the expression 10+[5(23-18)]/5, you need to perform the operations inside the brackets first. Subtract 18 from 23 to get 5, then multiply 5 by 5, resulting in 25. Next, divide 25 by 5 to get 5. Finally, add 10 to 5, giving a final answer of 15.
6. To determine the number of boxes needed to ship 492 shirts if each box can hold 24 shirts, divide 492 by 24. The quotient is 20.5, but since we cannot have a fraction of a box, we round up to the nearest whole number, which is 21. Therefore, it will take 21 boxes to ship all 492 shirts.
