Answer:

B = 15

Step-by-step explanation:

We can immediately take out y since there are no negatives in the picture.

3y + 2y = 5y so we are going to divide by 5 at one point, so it can't be C.

That leaves us with A and B, eventually the equation is 75/5, which equals 15 and not 16, so the answer is B.

The answer is B because it is 80=5y+5 and if you subtract 5 it’s 75=5y and if you divide by 5 it’s +16

Find the distance between points M (6,16) and Z (-1,14) to the nearest tenth, please help step by step

insens350 [35]

The distance between 2 points P(a, b) and Q(c,d) is given by the formula:

$\displaystyle{d= \sqrt{(b-d)^2+(a-c)^2}$ ,

Apply the formula for the points M(6, 16) and Z(-1, 14):

$\displaystyle{d= \sqrt{(16-14)^2+(6-(-1))^2}= \sqrt{2^2+7^2}= \sqrt{4+49}= \sqrt{53}\approx 7.28$

which rounded to the nearest tenth is 7.3 (units)

Answer: 7.3 units
