We want to get b alone so I would start by multiplying 2 to get it on the other side of the = sign. So then I have 2L=a-b. I would subtract a on both sides and then I would have 2L-a= -b. We don't want a -b so I would multiply everything by -1 so then the answer would then be a positive b= -2L+a

Answer:

-(2L-a) or -2L+a

Step-by-step explanation:

We want to isolate the variable, so multiply both sides by 2 to cancel out the division. Now subtract a on both sides and multiply both sides by -1. I hope this helps and please mark me brainliest. I just need 1 more. Please. I beg you.

Junnie walked for 2.5 hours at a distance of 3.2miles per hour. Maurice walked for 1.8 hours at a speed of 4.1 miles per hour.

GREYUIT [131]

We are given speed and time for Junnie and Maurice.

We will use speed distance formula here to find the distance covered by Junnie and Maurice.

The formula is given by:

$speed= \frac{distance}{time}$

$distance = speed * time$

Distance covered by Junnie:

We are given speed of Junnie as 3.2 miles per hour and time taken by her is 2.5 hours.

Plugging these values to find distance:

Distance = 3.2 * 2.5 = 8 miles

Distance covered by Maurice:

We are given speed of Maurice as 4.1 miles per hour and time taken by her is 1.8 hours.

Plugging these values to find distance:

Distance = 4.1 * 1.8 = 7.38 miles

Distance covered by Maurice is 7.38 miles whereas that covered by Junnie is 8 miles.

(A) So it is clear that Junnie walked farther.

Now let us find how much farther did Junnie walked.

We can find that by finding the difference between the two distances.

Difference = Distance covered by Junnie - distance covered by Maurice

Difference = 8- 7.38 = 0.62

(B) So Junnie walked 0.62 miles farther.

A slide 4.1 meters long makes an angle of 35º with the ground. To the nearest tenth of a meter, how far above the ground is the

Step2247 [10]

length of the slide is lets say 'l' the height (h) opposite to the angle 28 is found by h=l*sin28 where sin28=0.47 approximately h=4.5*0.47 h=2.115m

Given A(0, 0) and B(60, 60), what are the coordinates of point M that lies on segment AB such that AM:MB = 2: 3?

elena-14-01-66 [18.8K]

The answer is (24, 24).
Solution:
To find the point M that divides segment AB into 2:3 or 2/3 ratio, we determine k by writing the numerator of the ratio over the sum of the terms in the given ratio. Then, we calculate for the coordinates of point M from the slope of the line segment and the coordinates of A = (x1, y1) = (0, 0) and B = (x2, y2) = (60, 60) using the equation
(x, y) = (x1 + k(x2 - x1), y1 + k(y2 - y1) )
Therefore,
M = (x, y) = (0 + (2/5)(60 - 0), 0 + (2/5)(60 - 0)) = (24, 24)
