What is 78 ÷ 5 and the remainder

The answer is: (15) and the remainder is (6)

~i really hope this helps, have a gr8 day my friend!~

Step-by-step explanation:

Step 1) Start by dividing 78 by 5 to get the decimal answer as illustrated below. Note that we round the answer if necessary, but don't worry, the final answer will still be exact.

78 / 5 = 15.60

Step 2) Next we take the Whole part of the answer in Step 1 and multiply it by the Divisor. As you can see, it does not matter if we rounded in the previous step because the Decimal part is ignored. Furthermore, the Divisor in 78 divided by 5 is 5. Thus, the Whole multiplied by the Divisor is:

15 x 5 = 75

Step 3) Finally, we will subtract the answer in Step 2 from the Dividend to get the answer. The Dividend in 78 divided by 5 is 78. Thus, our final calculation to get the answer is:

78 - 75 = 3

That is all there is to it! Again, the answer is 3.

So here

78 ÷ 5 is 15.6 and it's remainder is 3

24/56=hx^7

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
