Answer:

8 and 7/10

Step-by-step explanation:

When adding mixed numbers, here's a method I use. I first pretend that that whole number part of the fraction doesn't exist, and that we'll deal with it later. So now we just have 2/5 and 3/10. Next, I make the denominators the same. 10 divided by 5 is 2, so multiply both the numerator and the denominator of 2/5 by 2. Now we have 4/10 + 3/10. This looks pretty easy now; since 4 + 3 is 7, our fraction is 7/10. Now throw those whole numbers back into the mix, (6 and 2,) and add them to get 8. Our final answer is 8 and 7/10.

2m - 6 = 8m then 3m =

Vinil7 [7]

Answer:

3m = -3

Step-by-step explanation:

You are given

2m - 6 = 8m,

hence,

2m - 8m = 6,

-6m = 6,

m = 6%2F%28-6%29,

m = -1.

Therefore, 3m = -3.

Can someone please be generous and help me

Ugo [173]

Answer:

The point slope form is $y-y_{1} =m(x-x_{1} )$

The slope(m) can be calculated using $\frac{y-y_{1} }{x-x_{1}}$ :

$(x, y)=(4,-3)\\(x_{1} ,y_{1} )=(5,0)\\\\\frac{0-(-3)}{5-4} =\frac{0+3}{1} =\frac{3}{1} =3$

Using Point One, the point-slope form is determined as:

$y-(-3)=3(x-4)\\y+3=3(x-4)$

The y-intercept(b) can be calculated as:

$(5,0)\\y=3x+b\\0=3(5)+b\\0=15+b\\b=-15\\(0,-15)$

Answer:

a) BE = 5; DE = 6; EF = 4

b) ∠EFC ≅ ∠DA.F ≅ ∠BDE or <em>b = e = f = i</em>

Step-by-step explanation:

Each short segment is the same length as the marked one it is parallel to.

E is the midpoint of BC, so BE = EC = 5.

ADEF is a parallelogram, so DE = A.F = 6.

D is the midpoint of AB, so AD = DB = 4. ADEF is a parallelogram, so ...

EF = AD = 4

__

As we have noted, AB║EF and DE║A.F, so corresponding angles and alternate interior angles are congruent. <em>b = e = f = i</em>
