Answer:

2 point questions would be 42.5

5 point questions would be 17

Step-by-step explanation:

40 + 2x = 125

Subtract 40 on both sides

40-40 + 2x = 125-40

You'll end up with:

2x= 85

So you'll have to do the opposite of multiplication for both sides, which is division.

2x/2 = 85/2 -------------> x= 42.5

----------------------------------------------------

40 + 5y = 125

Subtract 40 on both sides

40-40 + 5y = 125

You'll end up with

5x = 85

So you'll have to do the opposite of multiplication for both sides, which is division.

5x/5 = 85/5 ----------------> x= 17

I hope this helped !! :)

The area of a rectangle is 60 square inches. The length is x – 3, and the width is x + 8. Find the value of x, and the dimension

Vikki [24]

Answer:

x = 7

Length = 4 inches , Width = 15 inches

Step-by-step explanation:

PART 1 :

Area of rectangle = Length × Width

A = L × W

L = x - 3

W = x + 8

Therefore:

A = L × W

60 = ( x - 3 ) ( x + 8 )

( x - 3 ) ( x + 8 ) - 60 = 0

x^2 + 8x - 3x - 24 - 60 = 0

x^2 + 5x - 84 = 0

x^2 + 12x - 7x - 84 = 0

x ( x + 12 ) - 7 ( x + 12 ) = 0

( x + 12 ) ( x - 7 ) = 0

THEREFORE:

x = - 12 , x = 7

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

PART 2 :

L = x - 3

L = ( - 12 ) - 3

L = - 15

L = ( 7 ) - 3

L = 4

THEREFORE:

Length can not be a negative number. Hence, L can not equal to - 15.

L = 4 inches

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

W = x + 8

W = ( 7 ) + 8

THEREFORE:

W = 15 inches

What is 413,598 rounded to the nearest thousand?

Veronika [31]

Answer:

414,000

Step-by-step explanation:

When rounding to the nearest thousand, you need to focus on the hundreds column. Because the unit is 5, you round up (5,6,7,8,9 determine rounding up). Therefore the 3 in the thousands column becomes a "4".
