The number is 18.
In order to find this, we need to take each side and turn them into mathematics statements.
Five times the sum of a number and 3.
5(x + 3)
3 times the difference of twice the number and 1
3(2x - 1)
Now that we have these, we can set them equal to each other and solve.
5(x + 3) = 3(2x - 1) ----> Distribute
5x + 15 = 6x - 3 -----> Subtract 5x from both sides
15 = x - 3 -----> Add 3 to both sides
18 = x
Answer:
Step 1: $15
Step 2: 38%
Step-by-step explanation:
Step 1:
40 - 25 =15.
Therefore, the price would decrease by $15.
Step 2:
40 multiplied by .38 equals 24.80. You would round that up to 25. If you plugged in 37%, it would equal 25.20, which is over the price. Therefore the price decreased by 38%.
Answer:
4/9 for boys and 5/9 for girls
explanation:
there are 4 boys and 5 girls
so there are nine in total
if there are four boys and 9 in total then the fraction would be 4/9
and if there are 5 girls and 9 in total then the fraction would be 5/9
hope this helps and it plays Mark brainliest :D
Considering that each student has only one birthday, each input will be related to only one output, hence this relation is a function.
<h3>When does a relation represent a function?</h3>
A relation represents a function when each value of the input is mapped to only one value of the output.
For this problem, we have that:
- The input is the student's name.
- The output is the student's birthday.
Each student has only one birthday, hence each input will be related to only one output, hence this relation is a function.
