Answer:
Step-by-step explanation:
We have been given that Liam and his classmates bought a present for their teacher, evenly splitting the $120 among the 'e' of them.
This means that number of all students is 'e'. To find the cost of present for each student, we will divide 120 by e.
Since Liam had $250, so we need to subtract from 250 to get amount Liam has left:
Therefore, our required expression would be .
Answer:
Donovan babysat for 7 hours.

Numerator = Money Earned Denominator= Hours Worked
= 31.50 x 2= 63 63/9 = 7
14n +72
6n +72
14n +90
6n + 72 is the expression is equivalent to 10n + 81 - 4n - 9
An expression is combination of variables, numbers and operators.
The given expression is 10n + 81 - 4n - 9
Ten times of n plus Eighty one minus four times of n minus nine
In the given equation n is the variable, plus and minus are operators
10n + 81 - 4n - 9
We need to add the like terms.
Like terms means terms of variables with same power.
10n + 81 - 4n - 9
6n+72
Hence, 6n + 72 is the expression is equivalent to 10n + 81 - 4n - 9

Step-by-step explanation:
10n + 81 - 4n - 9
6n + 72
the father takes, the son takes 5 steps just to keep up. What is the ratio of
the number of steps the father takes to the number of steps the son takes? Add
labels to the columns of the table and place the ratio into the first row of
data. Add equivalent ratios to build a ratio table.
2. What can you say about the values of the ratios in the table?
(p.s the image attached is for question 1)
Answer:
3:5 is the ratio.
Step-by-step explanation:
The ratio of the number of steps of father to number of steps of son is 3:5.
The table forms as follows:
Steps by father Steps by son
3 5
6 10
9 15
12 20
15 25
a) The ratio of the number of steps of father to number of steps of son will be 3:5.
b) The table forms as follows:
father son
3 5
6 10
9 15
12 20
15 25
a) We can continue finding equivalent ratios by multiplying both sides of the ratio by different numbers, such as 3, 4, or any other value.
Multiply the first term by 2 to get 3 * 2 = 6. Multiply the second term by 2 to get 5 * 2 = 10.
- The equivalent ratio is 6:10.
In the ratio table, we can observe that the values of the ratios are always in the form of a fraction or as a simplified fraction.
=The ratios we have found so far, such as
3:5 and 6:10, = 3/5 and 3/5 respectively.
Thus the ratio of the number of steps of father to number of steps of son is 3:5.
b) The table forms as follows:
father son
3 5
6 10
9 15
12 20
15 25
