how would you write the following expressions using numbers, parentheses and other mathematical symbols.
1. Double the sum of twenty-five and eight.
2. The quotient of fifteen and three subtracted from the product of four and nine.
3.The difference between twenty and five multiplied by the sum of eight and two.
4.Three times the square root of the sum of nine and seven.
I'll get you started.
1.
2(25 + 8)
2.
(4 * 9) - (15/3)
I'll be glad to check your answers to the other two problems.
3.
(20-5)*8+2
4.(7+9)3
Is this correct? I seem to be struggling with this for some reason.
3. Good -- except it would be clearer if you put parentheses around 8 + 2
(20-5)*(8+2)
4. You didn't use the square root symbol. Let's see if I can do it.
3 √ (9 + 7)
Thank you so much for your help
You're very welcome.
1. Double the sum of twenty-five and eight:
To write this expression, start with the sum of 25 and 8, which is (25 + 8). Then, multiply that sum by 2 to double it. Thus, the expression is 2 * (25 + 8).
2. The quotient of fifteen and three subtracted from the product of four and nine:
To write this expression, start with the quotient of 15 and 3, which is 15 / 3. Then, multiply that quotient by the product of 4 and 9, which is (4 * 9). Finally, subtract the quotient from the product. Thus, the expression is (4 * 9) - (15 / 3).
3. The difference between twenty and five multiplied by the sum of eight and two:
To write this expression, start with the difference between 20 and 5, which is (20 - 5). Then, multiply that difference by the sum of 8 and 2, which is (8 + 2). Thus, the expression is (20 - 5) * (8 + 2).
4. Three times the square root of the sum of nine and seven:
To write this expression, first find the square root of the sum of 9 and 7, which is √(9 + 7). Then, multiply that square root by 3. Thus, the expression is 3 * √(9 + 7).
