Answer: 45
Step-by-step explanation:
30 times (3/2)
30 times 3 equals 90.
90 divided 2 equals 45.
Answer: x = -1 and y = -2
Step-by-step explanation:
You are given two expressions that have a relationship. There are two ways to solve this problem, but I will be going over the easy way. I'm assuming you know how to solve for one variable such as x? Well we can put the y varaible from the first equation in terms of x, from the second equation. Ill show you what I mean:
6x + 5(7x + 5) = -16
I replaced y in the first one in terms of x, so that we can solve just for x.
6x + 35x + 25 = -16
41x +25 = -16
41x = -41
x = -1
Now simply find y by plugging the now known x value into either equation
y = 7(-1) + 5
y = -2
The equation that models the data on pandas is FV = 25(1.066)^t.
<h3>What models the data?
</h3>
The formula for calculating future value of the pandas is:
FV = P (1 + r) ^n
- FV = Future value
- P = Present value
- R = annual population growth
- N = number of years
FV = 25(1.066)^t

Answer:
$149.60
Step-by-step explanation:
12% = .12
.12 × 170= 20.40
$170- 20.4= $149.60
An equation whose roots are x=3 and x=11 is
|(x-3)(x-11)|=0
We can check that, plugging in x=3 or x=11, makes both sides of the equation equal.
