The isosceles triangle has a perimeter of 7.5 m. which equation can be used to find the value of x if the shortest side

(7.5-2.1) /2

If the shortest side measures 2.1 m.

7.5-2.1 =5.4. Then divide by 2 each side is 2.7m

The equation for finding the value of x is 2x + 2.1 = 7.5 and the value of x is 2.7 m.

Step-by-step explanation:

Perimeter of the isosceles triangle = 7.5 m

Length of the shortest side = 2.1 m

Let the length of each of the other sides of the triangle = x meter

Then the equation for the perimeter of the triangle becomes:

Sum of 3 sides f the triangle = 7.5 m

=> 2*x + 2.1 = 7.5

=> 2*x = 7.5 - 2.1 = 5.4

=> x = 5.4/2 = 2.7 m

So the relevant equation for finding the value of x is 2x + 2.1 = 7.5 and the value of x is 2.7 m.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
