Draw a quick picture of 3 hundreds, 5 tens and 7 ones. what number does your quick picture show? write in the three different ways

In the figure attached, the quick picture can be seen. See the second picture for clarification.

Another way to represent that number is in a table format, as:

Hundreds   tens   ones

      3             5         7

Finally, 3 hundreds 5 tens and 7 ones are equal to 300 + 50 + 7 = 357

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

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
