Answer:

x = 4

Step-by-step explanation:

<em>Perimeter of triangle = sum of all sides</em>

Side 1: 14 - 2x

Side 2: 3x - 1

Side 3: 2x + 1

<em>Perimeter= side 1 + side 2 + side 3</em>

26 = 14 - 2x + 3x - 1 + 2x + 1

26 = 14 - 1 + 1 - 2x + 3x + 2x

26 = 14 + 3x

3x = 12

x = 12/3

x = 4

If 7 times a number is decreased by 33 the result is 15 less than 10 times number . Find the number

Anna11 [10]

First we set up the equation:
7n-33=10n-15
And then we subtract the common factors:
10n-7n
-15+33
3n= 18
Then we divide:
18/3
n=6

Hi can someone please help me with this i will give you five stars!!

Step-by-step explanation:

Let's look at what we know. We know that...

P=2000

r=0.04 (Change 4% to a decimal)

t=7 (25 years minus 18 years equals 7)

n=1

Since we are compounding each year, we need to use this equation: $P(1+\frac{r}{n} )^{nt}$

Now just plug the numbers in: (Answer to #1:) $2000(1+\frac{0.04}{1} )^{(1*7)}$

This equals 2631.86

When we round, this equals to $2,632. (Answer to #2).
