-3 1/3b =5 what is the value of b?

zysi [14]

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 lines are shown. A line with points T, R, W intersects with a line with points S, R, V at point R. Another line extends from p

Marrrta [24]

Answer:

The vertical angles are ∠ WRS and ∠ VRT ⇒ 2nd answer

Step-by-step explanation:

* Lets explain the meaning of the vertical angles

- Vertical angles are the angles opposite to each other when two lines

are intersected

- The vertical angle are equal in measures

- Look to attached figure which represents the lines

∵ Line TW intersects line SV at R

∴ ∠ WRV and ∠ SRT are vertical angle

∴ ∠ WRS and ∠ VRT are vertical angle

∵ RU is between the rays of angle VRW

∴ RU intersects the lines TW and SV at R

∴ No vertical angles between RU and the other two lines because

it intersects them its endpoint R

* Now lets look to the answer to chose the right one

- ∠ WRU and ∠ SRT are not vertical angles

- ∠ WRS and ∠ VRT are vertical angles 

- ∠ VRU and ∠ TRS are not vertical angles

- ∠ VRT and ∠ SRT are not vertical angles

A crew of loggers cleared ½ acre of lumber in 4 days. How long will it take the same crew to clear 2 ¾ acres of lumber?

Tanzania [10]

You can use a proportion

1/2(acres) 2(3/4)acres
-------------- = --------------
4(days) x(days)

4*2(3/4) = 6
6/(1/2) = 12

It would take 12 days.

Hope this helped☺☺
