Let g the number of green, y the number of yellow and b the number of blue marbles respectively.

We have

g + y + b = 694 (we will call this equation 1)

Also, b = 3*y (yellow marbles are three times as many as blue marbles), so equation 1 becomes

g + y + 3y = 694

But, g = b - 90 (green marbles are as many as blue marbles - 90)
and because b = 3*y, we have that g = 3*y - 90

So, equation 1 is now

3y - 90 + y + 3y = 694
7y - 90 = 694

We add 90 to both sides so

7y = 694 + 90 = 784

We divide each side by 7, so finally

y = 112

and we have

b = 3*y = 3*112 = 336
and
g = b - 90 = 336 - 90 = 246

To check if our results are correct, we can see that

g + b + y = 246 + 336 + 112 = 694,

so we are indeed correct.

Let the number of blue marbles be x

number of yellow marbles = x/3

number of green = x- 90

ATQ

x + x/3 + x - 90 = 694

2x + x/3 = 784

(6x + x)/3 = 784

7x/3 = 784

x = 784 x 3/7

x = 112 x 3

x = 336

number of blue marbles = 336

Answer: A

Step-by-step explanation:

For this problem, we need to understand how translations work.

As you can see, the triangles only slide to the right side, along the x axis. Therefore, we can eliminate B and C.

Now, we can see that the triangle has shifted by +8 units. Therefore, A is the correct answer.

MrRissso [65]

The age of the van owned = 12 years

The age of the truck owned  = 29 years

Step-by-step explanation:

Here, the given question is INCOMPLETE.

Laura takes very good care of her vehicles. She owns a blue van and a red truck. Although she bought them both new, she has owned the truck for 17 years longer than she has owned the van. If the sum of the ages of the vehicles is 41 years, how old is the van and how old is the truck?

Let us assume the number of years Laura has owned the van = S years

So, according to the question:

The number of years she has owned truck = S + 17 years

Now, Sum of the age of ( Truck + Van)  = 41 years

⇒ (S + 17 years) + (S years)  = 41 years

or, 2 S +  17 = 41

or, 2 S  = 4 1 -1 7 = 24

or, S  = 24/2 = 12 years

or, S  = 12 years

Hence the age of the van owned = 12 years

The age of the truck owned  = S  + 17  = 12 + 17 = 29 years
