Answer:
Subtract the sum of the three test scores from the product of 75 and 5, and then divide the result by 2.
Step-by-step explanation:
From the question:
100, 70, 85 on three of her five tests
Total number of test = 5
mean of the five scores is 75
mean = average of the five scores
Average score = Total score / total number of test
Total score = Average score * total number of test
= 75*5 =375
to find remaining two tests' scores
Total score - the 3 scores from question
= 375 - 100 - 70 - 85
=120
If u want to find the score of each of the unknown test
From question:
She could not remember the other two scores, which were the same.
Thus,
The score of one test
= 120/ 2
=60

Assume a mats price from the start is "X" USD. Write an expression for what the mat would cost after being reduced by P % (unknown amount of percentage)
Answer:
Step-by-step explanation:
[tex]cost \ price = X\\Deduction = P \%\\Deduction \ Price = P \% of X = \frac{P}{100} \times X = \frac{XP}{100} \\\\Cost \ price \ after \ deduction = X -\frac{XP}{100}[/tex]
OR SIMPLIFY FURTHER
[tex]X - \frac{XP}{100} = X( 1 - \frac{P}{100} )[/tex]

At science camp, the kitchen served half of their blueberries with breakfast. After dinner, they put the remaining 5,270g, end text of berries on top of their ice cream dessert.
How many kilograms of blueberries did the science camp start with?
_____ kilograms?
The science camp started with 10.54 kilograms of blueberries.
To find the number of kilograms of blueberries the science camp started with, first need to calculate the initial weight of the berries.
Given that the remaining weight of blueberries after dinner was 5,270g, and this represents half of the total blueberries served, we can determine the total weight before serving by doubling the remaining weight.
Double the remaining weight: 5,270g x 2 = 10,540g
Now, we need to convert the weight from grams to kilograms since we're looking for the weight in kilograms.
1,000 grams in a kilogram, so we can divide weight in grams by 1,000.
Weight in kilograms: 10,540g ÷ 1,000 = 10.54kg
Therefore, the science camp started with 10.54 kilograms of blueberries.
