If a+b+b =24 and b-a =4 what is a?​
Lyrx [107]

Answer:

a = 5 1/3

Step-by-step explanation:

a+b+b = 24

a + 2b = 24

b-a =4

a = b - 4

b - 4 + 2b = 24

3b = 24 + 4

b =28/3

substitute this in a = b - 4

a = 28/3 - 4

a = 28/3 - 12/3

a = 16/3

a = 5 1/3

Tell whether the pair of polygons is similar. Explain why or why not.
Savatey [412]

9514 1404 393

Answer:

  not similar

Step-by-step explanation:

Similar polygons have all corresponding angles congruent, and corresponding sides proportional.

The sides lengths guarantee the polygons are parallelograms, so one pair of angles being congruent is sufficient to ensure that all corresponding angles are congruent.

The ratio of side lengths in the left polygon is 13/8, and the ratio of side lengths in the right polygon is 5.2/2.4 = 13/6. These are different ratios, so the corresponding sides are NOT proportional.

The figures are NOT SIMILAR.

5x+5y=-30 find the x and y intercept
Masja [62]

<em>The x and y intercept of 5x + 5y = -30 are (-6, 0) and (0, -6) respectively.</em>

<h2 /><h2>Explanation:</h2>

The Standard Form of the equation of a line is given by:

Ax+By=C \\ \\ A,B,C \ Real \ Constants \ and \ A>0

So:

5x+5y=-30

is written in Standard Form. The x and y intercepts are:

x-intercept: \ (x,0) \\ \\ y-intercept: \ (0,y)

So:

FOR X-INTERCEPT:

Let's \ set: \\ y=0 \\ \\ 5x+5(0)=-30 \\ \\ Isolating \ x: \\ \\ 5x=-30 \\ \\ x=-\frac{30}{5} \\ \\ \boxed{x=-6}

FOR Y-INTERCEPT:

Let's \ set: \\ x=0 \\ \\ 5(0)+5y=-30 \\ \\ Isolating \ x: \\ \\ 5y=-30 \\ \\ y=-\frac{30}{5} \\ \\ \boxed{y=-6}

Finally,<em> the x and y intercept of 5x + 5y = -30 are (-6, 0) and (0, -6) respectively.</em>
