Step-by-step explanation:
Maybe the big numbers make it confusing, so let's look at something simpler. If you start with 5 marbles and every day you add one marble to it how many will you have x days after startign the collection? Well on day 0 it's 5, on day 1 it's 6, because 5+1, on day 2 it's 5+2=7, and so on. You can write this as an equation, y = 5+x, where y is the new total and x is the number of days.
So let's move that thinking to this problem. 1990 is day 0 and you start with 3,500,000. Each year now instead of day you add 38,500. So year 0 has 3,500,000. year 1 has 3,500,000+38,500 = 3,538,500 and so on, where each year we add another 38,500. So just like in the simpler example we can rewrite this. y = 3,500,000 + 38,500x. Linear means that the x is just an x instead of something like x^2, or 1/x or something else. Just normal x.
The value of ? and X are 12 and 24 respectively
<h3>Similarity theorem of a triangle</h3>
A triangles is 2D shape with three sides and angles.
From the given diagram, the ratio of similar sides is equal to a constant as shown;
15/20 = 9+15/20+x
Cross multiply
15/9+15 = 20/20+x
15/24 = 20/20+x
Comparing with the given ratio
? = 24
X = 20+x
Find x
15(20+x) = 480
300 + 15x = 480
15x = 180
x =12
Fro the given expression
x/32 = 9/?
12/32 = 9/?
12 ? = 32 * 9
? = 24
Hence the value of ?and x from the given diagram is 12 and 24 respectively

Let's see what to do buddy...
Step-by-step explanation:
_________________________________
STEP (1)
We have to know how many pets does the pet store have.
Look : 10 + 9 + 8 = 27
So the pet store completely have 27 pets.

STEP (2)
Mario randomly selects a pet :
Is the Probability of selecting a cat.
##############################
Is the Probability of selecting a dog.
