The ratio of the sides of a triangle is 2 6 7 if the perimeter of the triangle is 195 meters

timama [110]

Answer: 91m

Step-by-step explanation:

We set three sides of the triangle equal to 2x,6x,7x; because there is the ratio 2:6:7, which x is a common factor of these three sides.

P = a + b + c

2x + 6x + 7x = 195

15x = 195

x = 13

7x suppose be the longest side of the triangle, we plug in 13 for x, then:

7x = 7(13) = 91 m

-4(3+n)>-32 Please Solve just like the picture

OLEGan [10]

$n$

The number line is shown in figure attached below.

Step-by-step explanation:

We need to solve the inequality $-4(3+n)>-32$ and find value of n.

Solving the inequality:

$-4(3+n)>-32$

Multiplying -4 with terms inside the bracket.

$-12-4n>-32$

Adding 12 on both sides:

$-12-4n+12>-32+12$

$-4n>-20$

Divide both sides by -4 and reverse the inequality:

$n$

The number line is shown in figure attached below.

The number line starts with 5 with unfilled hole because n is less than 5 and moves towards left of the number line, because all values less than 5 are included in number line.
