Answer:

x=4

Step-by-step explanation:

10(x+2)=5(x+8)

10x+20=5x+40

10x-5x+20-20=5x-5x+40-20

5x/5=20/5

x=4

2. Write the slope-intercept form of the equation for each graph described. Line passing through (-5, 12) and parallel to the li
Nostrana [21]

Answer:   y = 2x+22

========================================================

Explanation:

The equation y = 2x+5 is in the form y = mx+b

m = 2 = slope

b = 5 = y intercept

Parallel lines have equal slopes, but different y intercepts. So the answer will be in the form y = 2x+c, where b and c are different numbers. Since b = 5, this means c must be some other number. If c = 5, then we'd have the exact same line.

Let's plug in (x,y) = (-5,12), along with the slope m = 2, and solve for c

y = mx+c

12 = 2(-5)+c

12 = -10+c

12+10 = c

22 = c

c = 22

Since m = 2 and c = 22, we go from y = mx+c to y = 2x+22

The equation of the parallel line is y = 2x+22

The graph is below.

Answer:

The range of possible values for the third side called c is;

11 > c or c < 11

Step-by-step explanation:

Here in this question, we are concerned with giving the range of the third side of the triangle.

What we will be using to get this range is the triangle inequality theorem.

Mathematically, the sum of the length of the two sides must be greater than the length of the third side.

So let’s call the third side c

Thus, the range of values we are to work with is;

5 + 6 > c

11 > c

At Roberta’s cafe half of her regular customers order her famous low-fat chicken sandwich. The probability of a regular customer
yuradex [85]

Answer:

The probability of losing weigth given that the sandwich was ordered is 80%.

Step-by-step explanation:

The probability of a regular costumer ordering the sandwich is said to be 50% and the probability of someone ordering that sandwich and losing weight is 40%. So we the probability of someone losing weigth if the sandwich was ordered is:

sandwich and losing weigh = (ordering sandwich)*losing weigth

losing weigth = (sandwich and losing weigth)/(ordeing sandwich)

losing wiegh = 40%/0.5 = 80%

The probability of losing weigth given that the sandwich was ordered is 80%.
