Josh biked 1 1/3miles to school callie biked 1/2 miles to school how many more miles did josh bike

Josh bike    miles more.

Step-by-step explanation:

Given:

Josh biked miles to school.

Callie biked miles to school.

Now, to find the miles more Josh biked than Callie.

So, to get the miles more Josh biked than Callie we subtract the miles Callie biked from the miles Josh biked:

 -  

Therefore, Josh bike miles more.

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400

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
