The two angles together form a straight angle, i.e. an angle of 180 degrees. This means that

$7x + 2x+27 = 180$

Sum like terms:

$9x+27 = 180$

Subtract 27 from both sides:

$9x = 153$

Divide both sides by 9:

$x = \dfrac{153}{9} = 17$

What is the equation in point-slope form of a line that passes through the points (-4, -1) and (5, 7)?

Setler [38]

Answer:

y + 1 = 8/9(x +4)

Step-by-step explanation:

Find the slope: [7- (-1)]/ [5 - (-4)] = 8/9

Using (-4, -1)

y-(-1) = 8/9[x- (-4)]

y + 1 = 8/9(x +4)

What is the square root of 5x^2 = 300

vesna_86 [32]

So, values of x are: $x=2\sqrt{15},\,\,x=-2\sqrt{15}$

Step-by-step explanation:

We need to find the square root of 5x^2 = 300

Writing in mathematical form:

$5x^2=300$

Divide both sides by 5

$\frac{5x^2}{5}=\frac{300}{5}$

$x^2=60$

Taking square root on both sides

$\sqrt{x^2}=\sqrt{60}$

$x=\pm (\sqrt{2\times 2\times 3\times 5})$

$x=\pm (\sqrt{2^2 \times 3\times 5})$

$x=\pm (2\sqrt{3\times 5})$

$x=\pm (2\sqrt{15})$

$x=2\sqrt{15},\,\,x=-2\sqrt{15}$

So, values of x are: $x=2\sqrt{15},\,\,x=-2\sqrt{15}$

Bowl A contains 6 apples and 3 mangoes this can be written as, Bowl B contain 8 apples and 2 mangoes this can be written as. Wha

Andrew [12]

Answer:

Bowl B contains 2 apples more than Bowl A and Bowl A contains 1 mango more than Bowl B.

Step-by-step explanation:

Number of apples in Bowl A = 6

Number of mangoes in Bowl B = 8

Difference in apples = 8 - 6 = 2

So, Bowl B contains 2 apples more than Bowl A.

Number of mangoes in Bowl A = 3

Number of mangoes in Bowl B =2

Difference in mangoes = 3 - 2 = 1

So, Bowl A contains 1 mango more than Bowl B.
