3(b+2) divided by 2 equal 4b-10 divided dy 4
Gwar [14]

Answer:

b=-11

Step-by-step explanation:

I assume you are looking to solve for the value of b.

<u>3(b+2)</u> x <u>2</u>= <u>4b-10</u>

    2       2      4

<u>6(b+2)</u> = <u>4b-10</u>

   4            4

x 4             x4

6(b+2) = 4b-10

6b+12=4b-10

-4b       -4b

2b+12=-10

     -12  -12

<u>2b</u>=<u>-22</u>

2      2

b=-11

find x please help me this is due soon and I don’t know what to do
anastassius [24]

Answer:

116

Step-by-step explanation:

a line is 180 degrees so subtract 64 and you get 116, that is your angle

Given: these two lines are parrallel cut by a transversal, 4 is 64 degrees

because 4 is given we know 6 is also 64 becasue they are alternative interior angles

all straight lines measure to 180 degrees so 3 and 5 become 116 because 180-64=116 (we also know these lines are parallel becasue 4 and 5 are supplementary, they add up to 180 as well.)

becasue 5 is 116 8 needs to be 64 and becasue 8 is 64 to equal 180 7 needs to be 116 (again, they need to add up to 180 becasue they are a straight line)

Rewrite the equation without absolute value <br> Y=|x-2|+|x+2|-|x-5| if x&lt;-2
Oxana [17]

Answer:

Step-by-step explanation:

Hey there!

In order to solve this equation, you need to first simplify and take the absolute value:

x+2+x+2-x+5

Now you need to simplify

x+9

So, the rewritten form of the equation is x+9

The ratio of the measures of the sides of a triangle is 8: 15: 17, and its perimeter is 480 in.. Find the measure of the shortes
lubasha [3.4K]

Answer:

96

Step-by-step explanation:

The ratio of the measure of sides of a triangle are 8:15:17

The perimeter is 480

8x + 15x + 17x= 480

40x= 480

x = 480/40

x = 12

Therefore the measure of the shortest side of the triangle can be calculated as follows

8x

8×12

= 96
