-3x + b = 6x

solve for x

Answers

Answer 1

Answer:

x = 1/9(b)

Step-by-step explanation:

Step 1: Subtract 6x from both sides.

[tex]-3x + b - 6x = 6x - 6x[/tex] [tex]-9x + b = 0[/tex]

Step 2: Subtract b from both sides.

[tex]-9x + b - b = 0 - b[/tex] [tex]-9x = -b[/tex]

Step 3: Divide both sides by -9.

[tex]\frac{-9x}{-9}= \frac{-b}{-9}[/tex] [tex]x = \frac{1}{9}b[/tex]

Therefore, [tex]x = \frac{1}{9}b[/tex].

A, B and C lie on a straight line segment.A, E and D lie on a straight line segment.BE = 1.8m, CD = 9m and BC = 1.7m.Work out the length of AB.Write your answer to two decimal places.

Answers

The relationship between the points is an illustration of similar shapes.

The length of AB is 0.43

The given parameters are:

[tex]\mathbf{BE = 1.8}[/tex]

[tex]\mathbf{CD = 9}[/tex]

[tex]\mathbf{BC = 1.7}[/tex]

From the question (see attachment), we have the following observations:

BE corresponds to CDAB corresponds to AC

So, the equivalent ratio is:

[tex]\mathbf{AB:BE =AC:CD }[/tex]

Substitute known values

[tex]\mathbf{AB:1.8 =AC:9 }[/tex]

Express as fractions

[tex]\mathbf{\frac{AB}{1.8} =\frac{AC}{9} }[/tex]

Multiply both sides by 1.8

[tex]\mathbf{AB =\frac{AC}{5} }[/tex]

AC = AB + BC

So, we have:

[tex]\mathbf{AB =\frac{AB + BC}{5} }[/tex]

Substitute 1.7 for BC

[tex]\mathbf{AB =\frac{AB + 1.7}{5} }[/tex]

Multiply through by 5

[tex]\mathbf{5AB =AB + 1.7}[/tex]

Collect like terms

[tex]\mathbf{5AB -AB =1.7}[/tex]

[tex]\mathbf{4AB =1.7}[/tex]

Divide both sides by 4

[tex]\mathbf{AB=0.425}[/tex]

Approximate

[tex]\mathbf{AB=0.43}[/tex]

Hence, the length of AB is 0.43

If mZx = 126° Calculate mZy

Answers

< x has the same measure as the supplement of < y because they are Alternate interior angles.

Since m < x = 126°, then the supplement of < y must also be m < 126°.

To solve for y:
m < y = 180° - 126°
m < y = 54°

Therefore, the < y has a measurement of 54°

I have no idea how to find multiple angles i was only taught how to find one..

Answers

The sum of all angles must equal 180°. Since you already have two angles for the larger triangle, all you need to do to find m < x is by subtracting m < 63° and m < 36° from 180°:

m < x = 180° - m < 63° - m < 36°
m < x = 81°

Therefore, < x = 81°

For the smaller triangle (acute), what you could do to find m < z is by subtracting m < x from 180°. We can do it that way because < x and < z are supplementary angles whose sum add up to 180°.

m < z = 180° - m < x
m < z = 180° - m < 81°
m < z = 99°

Therefore, < z = 99°

Lastly, to find m < y, subtract m < 13°and m < z° from 180°:

m < y = 180° - m < z° - m < 13°

m < y = 180° - m< 99° - m< 13°
m < y = 68°


Therefore, the measure of the following angles are:

< x = 81°
< y = 68°
< z = 99°

Answer:

36+63+_=180

Step-by-step explanation:

just add up everything in the smaller triangle to get 180

then ignore the line inside of the bigger triangle and repeat the first step, but only just look at the bigger one! that is how to do it, but I won't give the answer, good luck! ;)

it took jose two-thrids of an hour to complete his math homework on monday,three- fourths of an hour on tuewsday , and two- fifths of an hour on wednesday. how many hours did it take jose to complete his homework altogether

Answers

It took Jose an hour and 49 minutes to complete his homework! (109 minutes)

On Monday, Jose took 2/3 of an hour to complete his math homework. We know that is hour is 60 minutes. Divide 60 by 3 (the denominator) and you get 20. Multiply 20 x 2 (numerator) and you get 40 minutes! 2/3 of an hour is 40 minutes.

On Tuesday, Jose took 3/4 of an hour to complete his homework. Divide 60 by 4 (denominator), and you get 15! Multiply 15 x 3 (numerator) and you get 45. 3/4 of an hour is 45 minutes.

On Wednesday, Jose took 2/5 of an hour to complete his homework. Divide 60 by 5 (denominator), and you get 12. Multiply 12 x 2 (numerator) and you get 24! 2/5 of an hour is 24 minutes.

Finally, you add the three sums of minutes from each day. 40 + 45 + 24 = 109.

Subtract 60 from 109 (109 - 60) and you get a remainder of 49 minutes. This means that it took Jose and hour and 49 minutes to finish his homework.

What would you do to both sides of the equation to solve for x?
10x=5

Answers

First things first you see that your equation has a multiplication problem in the left side of the equals bar. Seeing this you would divide that one side by 10 but you want to be fair so you would do the same thing to the other side so you would have 5/10. After doing this the 10s cross eachother off and you are left with x=5/10. I hope this helps!
