<em>Question 1: </em>
For this case we have the following pattern of numbers:
24.3, 24, 23.7, 23.4
It can be seen that subtracting 0.3 from the first number of the pattern gives
Equally if we subtract 0.3 successively we obtain:
Thus, 0.3 must be subtracted from each term and the following numbers of the pattern shall be 23.1 and 22.8
Answer:
subtract 0.3 from each term
The next two numbers of the pattern are 23.1 and 22.8
<em>Question 2: </em>
For this case we have the following operation:
We note that the sum is greater than 1
The sum of two hundredth decimals does not necessarily have to be greater than 1.
Therefore, the correct option is: the sum is greater than 1 because the sum shades more than one hundredths grid.
Answer:
Option C
<em>Question 3: </em>
For this case we have to:
Being a, b, c decimal numbers, one of them was 0.34. Suppose
Thus:
We choose values for b and c, in order to obtain the number 2 as a result of the sum. We can choose infinite values so that equality is fulfilled
If and
we have:
Thus, Holland can add to the sum and
Answer:
<em>Question 4: </em>
For this case we have the following subtraction:
This operation is wrong, subtracting results in 1.04
Let's explain a model for Maysa:
We have the following expression
Rewriting each number in expanded form we have:
Using the distributive property we have:
Using the associative property we have:
Performing each operation:
Anwer:
The subtraction of Maysa is wrong, the correct answer is:
Answer:
The cost of one hot dog is $1.5 and the cost of one drink is $2.
Step-by-step explanation:
Let
<em>h</em> = the cost of a hog dog and <em>d</em><em> </em>= the cost of a drink
We know from the information given that:
- Carl bought 5 hot dogs and 3 drinks and paid $13.50. This is equal to
- Susan purchased 2 hot dogs and 3 drinks and was charged $9.00. This is equal to
So we have a system of equations
We can solve by elimination as follows:
Subtract from
Therefore
<em>h</em> = $1.5 and <em>d</em><em> </em>= $2
