Write a sentence as an equation using the given information in each problem. 1. Write the sentence as an equation.
the product of 371 and d is the same as 52

2. Write the sentence as an equation. n decreased by 320 is equal to 139

3. Write the sentence as an equation. 317 is equal to k plus 110

4. Write the sentence as an equation.
the total of 374 and k is the same as 305

5. Write the sentence as an equation. 398 is the same as d plus 6

1. 371 × d = 52

2. n - 320 = 139

3. 317 = k + 110

4. 374 + k = 305

5. 398 = d + 6

Step-by-step explanation:

1. 371 × d = 52

d = 52/371

d = 0.14016172506

2. n - 320 = 139

n = 139 + 320

n= 459

3. 317 = k + 110

k = 317 - 110

k = 207

4. 374 + k = 305

k = 305 - 374

k = -69

5. 398 = d + 6

d = 398 - 6

d = 392

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
