Answer:

b = (-3)/2

Step-by-step explanation:

Solve for b:

(-10 b)/3 = 5

Multiply both sides of (-10 b)/3 = 5 by -3/10:

(-3 (-10) b)/(10×3) = (-3)/10×5

(-3)/10×(-10)/3 = (-3 (-10))/(10×3):

(-3 (-10))/(10×3) b = (-3)/10×5

(-3)/10×5 = (-3×5)/10:

(-3 (-10) b)/(10×3) = (-3×5)/10

(-10)/10 = (10 (-1))/10 = -1:

(-3-1 b)/3 = (-3×5)/10

(-3)/3 = (3 (-1))/3 = -1:

--1 b = (-3×5)/10

(-1)^2 = 1:

b = (-3×5)/10

5/10 = 5/(5×2) = 1/2:

Answer:  b = (-3)/2

-3_1/3(b) = 5

I assume you mean -3_1/3 and not

-31/3.

(-10b/3) = 5

Multiply both sides by 3 to clear the fraction.

-10b = 15

b = -15/10

Reduce.

b = -3/2

Simplify to create an equivalent expression. 8−4(−x+5)
White raven [17]
8 - 4(-x + 5)

As you already know, in order to find the equivalent expression to our already given one, we have to simplify it first :)

8 +4x - 20

**Remember that a negative times a negative is always a positive!!**

Add like terms.

4x + (8 - 20)

Simplify.

4x + (-12)

Get rid of parenthesis.

4x - 12

Look at our answer choices.

Our answer is a. 4x - 12

~Hope I helped!~

Quadrilateral ABCD is a kite. If AD=AB, find AD<br><br> A. 5/3<br> B. 7<br> C. 5/7<br> D. 22
ICE Princess25 [194]
AD = AB

AD = 2r+8
AB = 5r-13

we need to find the value of r to find the total length

so 2r+8 = 5r-13
subtract 2r from each side:
8 = 3r -13
add 13 to each side:
21 = 3r
divide both sides by 3
r = 21 / 3 = 7
r=7
 now we know r, so replace r with 7 in the equation for AD

AD = 2r+8 = 2(7) +8 = 14 +8 = 22

 the answer is D. 22
