What is the solution to the linear equation?

patriot [66]

Equation: 2/5 + p = 4/5 + 3/5p

Simplify Both Sides:
p + 2/5 = 3/5p + 4/5

Subtract 3/5p from both sides:
p + 2/5 - 3/5p = 3/5p + 4/5 - 3/5p

2/5p + 2/5 = 4/5

Subtract 2/5 from both sides:
2/5p + 2/5 - 2/5 = 4/5 - 2/5

2/5p = 2/5

Multiply both sides by 5/2

(5/2) * (2/5p) = (5/2) * (2/5)

p = 1

Answer: p = 1

Hope that helps!!! (Answer: Letter Choice (A), p = 1

There are 34 Pre-K children and 29 kinder garden children on the playground, some boys and some girls. The ratio of boys to girl

Natali [406]

There are 27 boys on the playground.

Step-by-step explanation:

No. of Pre-K children = 34

No. of kindergarten children = 29

Total no of children = 29+34 = 63

Ratio of boys to girls = 3:4

Total ratio = 3+4 = 7

Therefore,

boys proportion = $\frac{3}{7}$

Total number of boys = $\frac{3}{7}\ of\ total\ number\ of\ children$

$Total\ number\ of\ boys = \frac{3}{7} *63\\Total\ number\ of\ boys = \frac{189}{7} \\Total\ number\ of\ boys = 27$

There are 27 boys on the playground.

The function f(x)=g(x), where f(x)=2x-5 and g(x)=x^2-6. The table below shows the process of solving using successive approximat

valkas [14]

Answer:

The positive solution is 2.4.

Step-by-step explanation:

The given functions are

$f(x)=2x-5$

$g(x)=x^2-6$

It is given that

$f(x)=g(x)$

$2x-5=x^2-6$

$0=x^2-6-2x+5$

$0=x^2-2x-1$

The quadratic formula:

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$x=\frac{2\pm \sqrt{(2)^2-4(1)(-1)}}{2(1)}$

$x=\frac{2\pm \sqrt{8}}{2}$

$x=\frac{2\pm 2\sqrt{2}}{2}$

$x=\frac{2(1\pm \sqrt{2})}{2}$

$x=1\pm \sqrt{2}$

$x=2.4,-0.4$

Therefore the positive solution is 2.4.
