How many solutions does the equation have?
Elina [12.6K]

9514 1404 393

Answer:

  1 solution

Step-by-step explanation:

The coefficients of d are different on the two sides of the equation (3d vs 6d), so the equation has one solution.

__

Dividing by 3 gives ...

  d +11 = 2(d +33)

  d + 11 = 2d + 66

Adding -d-66 to both sides gives ...

  -55 = d . . . . . . the one solution

В рулоне 32 метров ткани. Отрезали одну восьмую часть. Сколько
chubhunter [2.5K]

Answer:

28 meters

Step-by-step explanation:

<u><em>The question in English is</em></u>

On a 32-meter roll of fabric, it cuts an eighth of the total. How many meters of fabric are left in a roll?

step 1

we know that

To find out how many meters of fabric were cut, multiply the total meters by the fraction that was cut

32(\frac{1}{8})=4\ m

step 2

To find out how many meters of fabric are left, subtract the meters of fabric that were cut from the total meters of fabric

so

32-4=28\ m
