5c + 3 a =25  c is the cost of children ticket and a is the cost for adult tickets.

4c +4a =28

Now multiply first equation by 4 and the second equation by 5

20c +12a =100
20c +20a = 140

Now subtract equation 2 from 1 we have -8a =-40 a = 5
Now substitute the value of a in equation 1    5c =25-15 c= 10/5 =2

children's ticket cost $2

<h3>What is a fraction number?</h3>

A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.

Kelly spends 1/4of her Savings on driving lessons. Kelly then spends 2/3 of her remaining Savings on a new car.

Then the amount of the fraction of Savings has Kelly spent will be

⇒ 1/4 + (1 – 1/4) × 2/3

⇒ 1/4 + 3/4 × 2/3

⇒ 1/4 + 1/2

⇒ 3/4

Is the quotient of 3.6 divided by 9 greater or less than 1?
Kisachek [45]

Answer:

<h2>"less than 1".</h2>

Step-by-step explanation:

The given quotient is

\frac{3.6}{9}

In this case, before solving the quotient, we can ensure that its result is less than 1, because the numerator is less than the denominator, this is called a "proper fraction", and those fraction always ends in a number less than 1.

\frac{3.6}{9}=0.4

Therefore, the answer is "less than 1".

On a balanced scale are a 25-g mass, a 100-g mass, and five identical blocks marked X as shown. What is the mass of each block m
expeople1 [14]

Answer:

One block - 15

Two blocks - 30

Three blocks - 45

Four blocks - 60

Five blocks - 75

Equation: 25 + 5x = 100

Step-by-step explanation:

This is a pretty simple problem. The scale is balanced and from what we know, the 100 and 25 are on different sides. If we want the scale to be balanced, then we have to solve the equation:

25 + 5x = 100.

(We have the 5x because we have 5 blocks that are marked as x)

subtract 25 from both sides

25-25 + 5x = 100-25

5x = 75

the following step is to divide both sides by 5.

5x/5 = 75/5

x = 15

Now that the equation is solved, we know that ONE blocked marked as X equals 15-g.

(All five of them equal 75-g)
