Which of the following expressions correctly use mental math to find 4x59 all that apply. (4x60)-(4x1) 4x(50x9) 4+(50x9) (4x50)+(4x9) 4+50+9
The following expressions correctly use mental math to find 4x59:
(4x60)-(4x1)
4x(50x9)
(4x50)+(4x9)
4+50+9
To find the value of 4x59 using mental math, we can consider the following expressions:
1. (4x60)-(4x1)
To find this value, we can see that multiplying 4 by 60 gives us 240, and multiplying 4 by 1 gives us 4. Subtracting 4 from 240, we get 236. So, this expression correctly uses mental math to find 4x59.
2. 4x(50x9)
To find this value, we can multiply 50 by 9 first, which gives us 450. Then, multiplying 4 by 450 gives us 1800. So, this expression also correctly uses mental math to find 4x59.
3. 4+(50x9)
To find this value, we can multiply 50 by 9 first, which gives us 450. Then, adding 4 to 450 results in 454. So, this expression correctly uses mental math to find 4x59.
4. (4x50)+(4x9)
To find this value, we can multiply 4 by 50 and get 200. Then, multiplying 4 by 9 gives us 36. Adding 200 and 36 together, we get 236. So, this expression correctly uses mental math to find 4x59.
5. 4+50+9
To find this value, we can simply add 4, 50, and 9 together, which gives us 63. However, this expression does not correctly use mental math to find 4x59.
In conclusion, the expressions that correctly use mental math to find 4x59 are (4x60)-(4x1), 4x(50x9), (4x50)+(4x9), and 4+(50x9).
To find the product of 4 multiplied by 59 using mental math, we can examine the given expressions and evaluate them step by step:
1. (4x60)-(4x1): This expression suggests finding the product of 4 multiplied by 60, which equals 240, and then subtracting the product of 4 multiplied by 1 (4x1) from it. This simplifies to 240 - 4, resulting in the answer 236. However, this expression does not correctly calculate 4x59.
2. 4x(50x9): This expression implies multiplying 50 by 9, which equals 450. Then we multiply the result by 4, giving us 450x4. Solving this multiplication yields the answer 1800. Although this calculation involves mental math, it does not evaluate the expression 4x59 correctly.
3. 4+(50x9): This expression involves multiplying 50 by 9, resulting in 450. Then we add 4 to it, obtaining the sum 450 + 4 = 454. However, this expression does not provide the correct calculation for 4x59.
4. (4x50)+(4x9): Here, we multiply 4 by 50, which equals 200, and then add the product of 4 multiplied by 9 (4x9) to it. This simplifies to 200 + 36, resulting in the answer 236. However, this expression does not correctly calculate 4x59.
5. 4+50+9: This expression implies adding 4, 50, and 9 together, giving us the sum 63. However, this expression does not provide the correct calculation for 4x59.
None of the given expressions correctly use mental math to find 4x59. The correct answer can be obtained by multiplying 4 by 59 directly, which equals 236.
