7.04× 10^5

Step-by-step explanation:

6.72 x 10^5= 6.72 x 10^(4+1)= 6.72 x 10^1 ×10^4

= 67.2 x 10^4

(67.2 x 10^4)+ (3.2 x 10^4)

(67.2+3.2) × 10^4 = 70.4 × 10^4

7.04× 10^5 Step-by-step explanation:

The four numbers whose sum equals 0, none of which are opposites are

-2,  4, -9, 7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Four numbers:

-2,  4, -9, 7

We see that,

The sum of the four numbers is 0.

-2 + 4 + (-9) + 7

= -11 + 11

= 0

None of the numbers are opposite.

Thus,

The four numbers are -2, 4, -9, and 7.

Answer:

y = 2x + 2

Step-by-step explanation:

Add two to both sides.

Answer:

30.4%

1000 at £1.10

1000 x 1.10 = £1100

35% of 1000 is given away

1000 - 35% = 1000 - 350 = 650 left

35% of £1100 = £385, subtract to get £715 pounds worth of pins left

650 are left, with 385 pounds lost

60% of 650 = 390 pins sold at £3 each

40% of 650 = 260 sold at £5 for 2

3 x 390 = £1170 made from the first lot

260/2 = 130 x 5 = £650 made from the second lot

£1170 + £650 = £1820 from sales

Sales - cost to make - losses (giveaways) = profit value

1820 - 1100 - 385 = 335 pounds of profit

To find the gross profit margin, we take the profit, and find what percentage of the production cost it is.

335 is about 30.45% of 1100

30.45%, which is 30.4% to 1 decimal place.

Answer: the length in the drawing is 1.166666...ft or 14 inches.

Step-by-step explanation:

there are 0.75 ft in 9 inches, and 45/0.75=60. So, to find x you need to divide 70 by 60. :))

If you needed to answer in inches, I found my answer by dividing 45/9 which equals 5, so x=70/5. x=14 inches.

Answer:

20 is the total perimeter

Step-by-step explanation:

Answer:

6x + 2

Step-by-step explanation:

The area of a square is side length times itself.

In this problem, the area of one square is:

x², or x * x. So the side length of each square must be x.

In the rectangular shape, the area would be top * side. The side is equal to x because "side" is equal to the sides of the other squares (because a square's sides are all the same).

Plugging that into the equation, top * x = x, so the top must be 1.

There are 5 "full-length sides" on the two "full" squares on the left. Then, in the last skinny rectangle, there are two "tops", and one "full-length side".

Substitue the values of each side.

5x + 1 + 1 + x = 6x + 2
