Answer:

Equation used to solve for x is  2x + 2.1 = 7.5

The value equal sides of triangle is 2.7 m

Step-by-step explanation:

Given: The isosceles triangle has a perimeter of 7.5 m and the shortest side, y, measures 2.1 m.

We have to find the value of x.

Since y is shortest sides and the triangle given is isosceles thus the other two sides must be equal.

So, length of two equal sides is x.

Then equation becomes,

⇒  x + x + y = 7.5

⇒  2x + y = 7.5

Substitute the values of y = 2.1 , and solve for x, we have

⇒  2x + 2.1 = 7.5

Subtract 2.1 both side, we get,

⇒  2x = 7.5 - 2.1

Divide both side by 2, we get,

⇒  x = 2.7

Thus, the value equal sides of triangle is 2.7 m.

An isosceles triangle has 2 sides of the same length and one side that's not the same length.

So it says the shortest side, y, is 2.1m, so that means it's the side that is not the same length as the other two sides.

But the other two sides will be the same length. Let's make those 2 sides x.

The equation would be
x + x + 2.1 = 7.5

And with that you can find x.

On a recent trip, Juan started at an elevation of 1200 feet above sea level. He descended into a valley 20.4 feet below sea leve
liraira [26]

A would be the correct answer because he is up in elevation so that makes the 1200 positive and he goes down 20.4 which is negative and is goes that far down!!

hope this helps

100 POINTS FOR BOTH SIDES PLZZZ Plzzz help me with this SIDES
Oliga [24]

Answer:

Step-by-step explanation:

5.

point = (x, y)

A = (1\frac{1}{2}, 12)

B = (2\frac{1}{2}, 20)

C = (3, 24)

D = (3\frac{1}{2}, 28)

y/x ratios

\frac{12}{1\frac{1}{2} }

\frac{20}{2\frac{1}{2} }

24/3

\frac{28}{3\frac{1}{2} }

6.

(1 2/3, 3 1/3) = 3 1/3 ÷ 1 2/3 = 2

(1 1/4, 2 1/2) = 2 1/2 ÷ 1 1/4 = 2

(3, 7) = 7 ÷ 3 = 2 1/3

(4 1/2, 9) = 9 ÷ 4 1/2 = 2

The ratio 7/3 (x = 3 and y = 7) is not proportionally related to the others.

The other ratios are equal to each other and are therefore in proportion.

7. yes
