2a(5-b)=3b+7 solve for b<br> Step by step

Sidana [21]

<span>2a(5-b)=3b+7

<em>[open bracket]</em>
10a - 2ab = 3b + 7

<em>[solve for b, so we need to move all terms with b to the left]</em>
<em>[-3b on both sides]</em>
10a - 2ab - 3b = 3b + 7 - 3b
10a - 2ab - 3b = 7

<em>[move all those without b to the right]</em>
<em>[-10a on both side]</em>
10a - 2ab- 3b - 10a = 7 - 10a
-2ab - 3b = 7 - 10a

<em>[divide by -1 through to change b to be positive]</em>
2ab + 3b = 10a - 7

<em>[take b out as the common factor]</em>
</span>b(2a + 3) = 10a - 7<span>

<em>[divide by (2a+3) through]</em>
b = (10a -7)/(2a+3)

Beyonce is solving a system of equations:

aivan3 [116]

Answer:

x=5, y=4. (5, 4).

Step-by-step explanation:

2x-3y=-2

4x+y=24

------------------

-2(2x-3y)=-2(-2)

4x+y=24

----------------------

-4x+6y=4

4x+y=24

--------------

7y=28

y=28/7

y=4

4x+4=24

4x=24-4

4x=20

x=20/4

x=5

A horse takes 3 steps to walk the same distance for which a goat takes 4 steps. Suppose 1 step of the dog covers 1/2 of a metre.

almond37 [142]

Answer:

The goat would cover <u>9 meters</u> in taking 24 steps.

Step-by-step explanation:

<u><em>There is a mistake in the question so the correct question is below:</em></u>

A horse takes 3 steps to walk the same distance for which a goat takes 4 steps. Suppose 1 step of the horse covers 1/2 of a metre. How many metres would the goat cover in taking 24 steps?

Now, to find the meters goat cover in taking 24 steps.

As 1 step of horse covers = $\frac{1}{2} \ meter.$

So, 3 step of horse covers = $\frac{1}{2} \times 3$ $=\frac{3}{2} =1.5\ meters.$

<u><em>Thus, 3 steps of horse covers = 1.5 meter</em></u><em>s.</em>

<em>As given, the horse takes 3 steps to walk the same distance for which a goat takes 4 steps.</em>

<u><em>So, the distance covers by goat in 4 steps = 1.5 meters.</em></u>

Now, to get the meters goat cover in taking 24 steps by using unitary method:

If, the distance cover by the goat in 4 steps = 1.5 meters

So, the distance cover by the goat in 1 step = $\frac{1.5}{4}$

Thus, the distance cover by the goat in 24 steps = $\frac{1.5}{4}\times 24$

= $\frac{36}{3}$

= $9\ meters.$

Therefore, the goat would cover 9 meters in taking 24 steps.
