This isosceles triangle has two sides of equal length , a, that are longer than the length of the base , b. The perimeter of the
Sholpan [36]
We are give the equation of the perimeter of the triangle as follows:
2a + b = 15.7 
where b represents the base.

Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a

We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm

What does |x| mean? like what do the | | 'bars' symbolize or represent?
zavuch27 [327]

Answer: Absolute Value

Step-by-step explanation:

The | | is a symbol for absolute value. This signifies that the number inside would be positive. Now, this doesn't mean it will always be a number inside absolute value bars. It can also be expressions.

<u>Examples:</u>

|1|: Even though the number inside is a positive 1, we know that it cannot be negative under any circumstances. The only exception would be if there was a negative sign on the outside of the absolute value.

|-1|: We see that there is a -1 in the absolute value. This means that it is actually a 1, not -1. The absolute value is what makes everything inside positive.

|1-5|: To solve this, we know that 1-5=-4. Without the absolute value, the answer -4 would be correct. In this case, we have absolute value, so the answer is actually 4.

|x+2|: x+2 can easily be negative. This would happen is x was a negative number that is smaller than -2. x+2 can also be positive, but the absolute value guarantees that the ending result must be positive.

Darlene's dog weighed 5 times as much as Leah's Dog.Together,the dogs weighed 84 pounds. How much did each dog weigh?Write an eq
Triss [41]
Let d = Darlene's dog's weight
let l = Leah's dog's weight
 d = 5l
d + l = 84
 so, 5l + l = 84, which means 6l= 84   
so, l = 84/6 = 14d = 5(14) = 70    
<span>Darlene's dog = 70 lbs, Leah's dog = 14 lbs</span>
