The answer to the problems and how to solve it.

swat32

Let x and y represent angles 1 and 2, respectively. The given relations tell you

... x + y = 180 . . . . the sum of measures of a linear pair is 180°

... y = 2x + 6 . . . . angle 2 is 6 more than twice angle 1

One way to solve these is to add twice the first equation to the second.

... 2(x + y) + (y) = 2(180) + (2x +6)

Now, subtract 2x

... 3y = 366

... y = 122 . . . . divide by the coefficient of y

The measure of angle 2 is 122°.

The perimeter of a rectangle is 250 inches. if the length is 4 times as big as the width, what is the length and width of the re

yarga [219]

The length and width of the rectangle are 7.90 inches and 31.6 inches respectively

It is given that,

Let the length of the rectangle = l

Let the width of the rectangle = w

The perimeter of the rectangle = 250 inches

l x w = 250 ....eq 1

Then,

Length is 4 times as big as width

4l = w

We need to find, the length and width of the rectangle

Putting the value of w in eqn 1

We get,

$4l^{2} = 250$

$l^{2} = 62.5$

$l = \sqrt{62.5}$

$l = 7.90$

Similarly, we can get,

w = 4l

w = 4 x 7.90

w = 31.6

Hence, the length and width of the rectangle are 7.90 inches and 31.6 inches respectively

Slove : 28/36 = 14/y

Dafna1 [17]

Answer:

y = 18

Step-by-step explanation:

<h3>i) reduce the fraction with 4</h3>

$\frac{28}{36} = \frac{14}{y}$

$\frac{28 \div 4}{36 \div 4} = \frac{14}{y}$

$\frac{7}{9} = \frac{14}{y}$

<h3>ii) simplify the equation with cross multiplication</h3>

$\frac{7}{9} = \frac{14}{y}$

$7y = 14 \times 9$

$7y = 126$

<h3>iii) divide both sides of the equation by 7</h3>

$\frac{7y}{7} = \frac{126}{7}$

$y = 18$
