How do you work out 8x+3=8×+27

Alekssandra [29.7K]

Answer:

No solution

Step-by-step explanation:

8x + 8 = 8x + 27

You then cancel out the 8s. 8 - 8 = 0

Which leaves you with 8 = 27...

Since this is an untrue statement, the answer would be no solution, unless you typed it wrong.

Franco owns his landscaping business. He has to plant 425 plants in 47 places. After planting, how many plants will he have left

Lera25 [3.4K]

Answer:

423

Step-by-step explanation:

Number of trees to be planted = 425

Number of places where equal number of plants are to be planted = 47

The number of plants to be planted in each place is

$\dfrac{425}{47}=9.04255...\approx 9$

So, in each place 9 trees have to be planted.

Hence, the number of plants he will plant is $47\times 9=423$ .

Number of trees remaining will be

$425-9\times 47=2$

So, Franco can take home 2 plants for his own yard.
