Answer:

x=3.2

Step-by-step explanation:

8*0.4=3.2

We have that for the Question "The figures are similar, and the ratio of the perimeters is 2 : 5. Find x." it can be said that  the perimeters of x is

x=3.2

From the question we are told

The figures are similar, and the ratio of the perimeters is 2 : 5. Find x.

Generally the equation for the the ratio is mathematically given as

2=x

and

5=8

Therefore

[tex]x=\frac{2*8}{5}[/tex]

x=3.2

Therefore

the perimeters of x is

x=3.2

Answer:

$40 = 5a + 8s

Step-by-step explanation:

For this question all we need to know is that $40 is equal to 5 prices of the adult tickets plus the 8 prices of the student tickets. From here we can just give a variable to each price and make an equation, like so

Let "a" be the price of the adult ticket and

Let "s" be the price of the adult ticket, then....

$40 = 5a + 8s

(Just to make sure you understand I will repeat. 5 comes from he fact hat there were 5 adult tickets sold which means that there is 5 adult ticket prices in the $40, and exactly the same reasoning goes for the student tickets, 8 students tickets were sold which means the is 8 prices of the student ticket inside the $40.)

Answer:

[tex]4\frac{1}{2}[/tex]

Step-by-step explanation:

This question is basically saying: what is half of 7, or what is 7 divided by 2?

Based on this, it can be written both of the ways as:

»»  [tex]\frac{1}{2}[/tex] of 7  OR  7 ÷ 2

So, just solve using either one and you’ll get 4.5 or [tex]4\frac{1}{2}[/tex]. But since the question wants the answer to be a mixed number, then choose [tex]4\frac{1}{2}[/tex].

Answer:

  4

Step-by-step explanation:

We assume that point X is the intersection point of the medians. Then ...

  MQ = 3XQ

  3x -3 = 3(2x -6)

  3x -3 = 6x -18 . . .  eliminate parentheses

  15 = 3x . . . . . . . . . add 18-3x

  5 = x . . . . . . . divide by 3

Now, we can find XQ:

  XQ = 2x -6 = 2(5) -6

  XQ = 4

The answer is below

Step-by-step explanation:

Let x represent the number of days that fluffy eats wet food in a week and y represents the number of days that fluffy eats dry food in a week.

Hence:

x + y = 7                    (1)

Also, John wants to spend at most $9.00 on cat food each week. Hence:

1.5x + 0.75y ≤ 9       (2)

The list of possible points after solving graphically are:

(0,7), (6,0), (0,12) and (5, 2). If x,y > 0, then the point that satisfies the inequality is:

(5, 2) i.e. 5 wet food and 2 dry food
