Answer: The blank space in the equation is 4.

Step-by-step explanation: -6 x +2 is -12. -48/-12 is 4. Therefore, the blank space in the equation is 4.

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.

I got this right on edmentum.

Step-by-step explanation:

Answer:

2. y = -9x + 7

2. y = 3x - 2

3. y - 6 = 10(2x - 1)

1. 5x + 2y = 10

4. 5x = 3y + 9

3. y + 2 = 6(x - 4)

Step-by-step explanation:

Answer: Solution :  

Step 1 :

Make a scatter plot of Lily’s running data.

Step 2 :

To draw a trend line, use a straight edge to draw a line that has about the same number of points above and below it. Ignore any outliers.

Step 3 :  

Find the slope of the trend line.

The line passes through points (2, 20) and (4.5, 45).

Use the slope formula.  

m  =  (y2 - y1) / (x2 - x1)

Substitute x1, = 2, y1 = 20, x2 = 4,  and y2 = 45.

m  =  (45 - 20) / (4.5 - 2)

m  =  25 / 2.5

m  =  10

Step 4 :  

Find the y-intercept of the trend line.

Slope-intercept form equation of a line :  

y  =  mx + b

Plug y = 20, m = 10 and x = 2.  

20  =  10 · 2 + b

20  =  20 + b

Subtract 20 from both sides.  

0  =  b

Step 5 :  

Use your slope and y-intercept values to write the equation.

Slope-intercept form equation of a line :  

y  =  10x + 0

So, the equation for the trend line is

y  =  10x

Step-by-step explanation:

I am going to assume exponents for this question.

[tex]\frac{t^{8}}{t^{2}}[/tex]

When dividing exponents with the same base, it is simply subtraction, so 8 - 2 = 6 which produces the answer.

Step-by-step explanation:

Catherine bought apples and pears for the school picnic. If the total fruit is less than 100, then the correct equation for this will be y<100-x and y<x. Hence, option C is correct.

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the given data in the equation,

Catherine bought apple and pears.

The overall quantity is less than 100

Let the number of apples is x and,

The number of pears is y.

She bought more apples than pears,

y<x.

And y < 100-x.
