I believe you solved for x, but did not plug it back into 7x-35 to get that segment’s length. The correct answer is 49.

Answer:

M; BM = 49

Step-by-step explanation:

The vertical mark between A and M and the vertical mark between M and B show that segments Am and MB are congruent. That makes point M the bisector of segment AB.

The two segments AM and MB are congruent, so their lengths are equal.

4x + 1 = 7x - 35

Subtract 7x from both sides.

-3x + 1 = -35

Subtract 1 from both sides.

-3x = -36

Divide both sides by -3.

x = 12

BM = 7x - 35 = 7(12) - 35 = 84 - 35 = 49

Answer: M; BM = 49

P/2 = 3/4 + p/3 solve for p Show your work It is URGENT

il63 [147K]

Step-by-step explanation:

p/2 = 3/4 + p/3

p/2 - p/3 = 3/4

(3p - 2p )/6 = 3/4

p/6 = 3/4

multiply both sides by 6

p = 3×6/4

=18/4

=9/2

=4.5

PLEASE HELP!!! Which rule explains why these scalene triangles are similar

olchik [2.2K]

Answer: Ratio of Parts

Step-by-step explanation:

$\text{Ratio of sides:}\ \dfrac{ST}{WS+ST}=\dfrac{66}{6+66}=\dfrac{66}{72}=\dfrac{11}{12}\\\\\\\text{Ratio of bases:}\ \dfrac{TU}{TU+UV}=\dfrac{44}{44+4}=\dfrac{44}{48}=\dfrac{11}{12}\\\\$

The ratios are equal so the triangles are similar.

I need help. Math is really hard

Answer:

The value of x in terms of b is: $\mathbf{x=-\frac{6}{2b}}$

The value of x when b is 3 is: x = -1

Step-by-step explanation:

We are given the function: $-2(bx-5)=16$

First we need to find

The value of x in terms of b

We need to find value of x

$-2(bx-5)=16$

Multiply -2 with terms inside the bracket

$-2bx+10=16$

Subtract 10 from both sides

$-2bx+10-10=16-10\\-2bx=6$

Divide both sides by -2b

$\frac{-2bx}{-2b}=\frac{6}{-2b}\\x=-\frac{6}{2b}$

So, The value of x in terms of b is: $\mathbf{x=-\frac{6}{2b}}$

The value of x when b is 3

We have the equation for the value of x in terms of b:

$\mathbf{x=-\frac{6}{2b}}$

Put b = 3

$x=-\frac{6}{2(3)}\\x=-\frac{6}{6}\\x=-1$

So, The value of x when b is 3 is: x = -1

Here is a diagram that represents (3.1) ⋅ (1.4).

Firdavs [7]

Step-by-step explanation:

1. solution,

length of rectangle A(l)=3.1units

breadth of rectangle A(b)=1units

now,

area of rectangle A=l×b

=3.1units×1units

=3.1 sq units

2.solution,

length of rectangle B(l)=3.1units

breadth of rectangle B (b)=0.4units

now,

area of rectangleB=l×b

=3.1units×0.4units

=1.24 sq units

3.solution,

length=3.1units

breadth=1.4units

area =lxb

=3.1units x 1.4units

=4.34units
