Write each expression without the absolute value symbol. |7-(12-x)|
Answers
The expression without the absolute value symbol is given as follows:
If x > 5, then |7 - (12 - x)| = -5 + x.If x = 5, then |7 - (12 - x)| = -5 + x.If x < 5, then |7 - (12 - x)| = 5 - x.What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|f(x)| = f(x), x ≥ 0.|f(x)| = -f(x), x < 0.The expression for this problem is given as follows:
7 - (12 - x).
The critical value of x is obtained as follows:
7 - (12 - x) = 0
7 - 12 + x = 0
x = 5.
Hence the expression is given as follows:
If x > 5, then |7 - (12 - x)| = -5 + x.If x = 5, then |7 - (12 - x)| = -5 + x.If x < 5, then |7 - (12 - x)| = 5 - x.More can be learned about the absolute value function at https://brainly.com/question/3381225

It will change the sign of 3.
t = 17 + 3
t = 20

Answer:
8% as a fraction can be expressed as 8/100 or 4/50.
Explanation:
Percentages are a way of expressing a number as a fraction of 100. The symbol % represents "per hundred" or "out of 100." So, 8% can be thought of as 8 out of 100 or 8/100.
When we convert a percentage to a fraction, the numerator (top part of the fraction) represents the percentage value and the denominator (bottom part of the fraction) is set to 100. This is because 100 represents the whole, and the numerator represents a part of that whole.
In this case, 8% as a fraction is 8/100, which can be simplified to 4/50.
Answer: hope this helps ♡
8% = \(\frac{8}{100}\) = \(\frac{2}{25}\)
Step-by-step explanation:
% = something out of a hundred (not out of 10)
eg: 25% = 25 out of a hundred
so 8% = (8 out of a hundred) \(\frac{8}{100}\) = \(\frac{4}{50}\) = \(\frac{2}{25}\) (simplified answer)
(100 divided by 2 = 50 50 divided by 2 = 25)
(8 divided by 2 = 4 4 divided by 2 = 2)

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Your fitness tracker overestimates the number of steps you take by 5%. The trackers indicates that you took 7350 steps today. Write and solve an equation to find the actual number of steps you took today.
Answers
The equation (1 + 0.05)x = 7350 to find the actual number of steps you took today will be 7,000.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
Your fitness tracker overestimates the number of steps you take by 5%. The trackers indicate that you took 7350 steps today.
Let x be the actual number of steps. Then the equation will be given as,
(1 + 0.05)x = 7350
x = 7350 / 1.05
x = 7,000
The actual number of steps you took today will be
(1 + 0.05)x = 7350
x = 7350 / 1.05
x = 7,000
The equation (1 + 0.05)x = 7350 to find the actual number of steps you took today will be 7,000.

In a sale, the price of a bike is reduced by 40%
The sale price of the bike is £192
How much did the bike cost before the sale?
Answers
Answer:
£320
Step-by-step explanation:
So
The sale price is reduced 40% of the actual price
Actual price - 40% = £192
Actual price is the 100% price of the bike.
100% - 40% = £192
60% = £192
60% of the actual price of the bike is £192 but we need to find 100%.
To do that we need to find the price of 1%. To find this value we divide 60 into 192
\(192 \div 60 = 3.2\)
£ 3.2 is the 1% of the actual price.
To find the actual price (100%), you multiply 3.2 by 100
\(3.2 \times 100 = 320\)
So the actual price is £320
Hope this helps :)
Step-by-step explanation:
£192 = 60% of the original price (reduced by 40%).
1% of the original price = 60%/60 = 192/60 =
= 64/20 = 16/5 = 3.2
100% of the original price = 100×1% = 100×3.2 = £320
the bike cost £320 before the sale.

The weight of Micheal's and Brittney's new puppies are shown in the table and graph. Whose dog gains more weight more quickly? Explain.
Answers
Answer:
Brittney's Puppy
Step-by-step explanation:
Michael's puppy gains 8.6 pounds in 1 month while Brittney's puppy gains 155 ounces in 1 month
Rate of increase in weight of Micheal's puppy is less than Rate of increase in weight of Brittney's, Brittney's puppy gains weight more quickly.
What is rate of change?Rate of change is the measure of how one quantity changes in respect to change in another quantity .
let when a quantity x changes from x₁ to x₂ then the quantity y changes with respect to x from y₁ to y₂
The Rate of Change of y w. r. t. x = ( y₂ - y₁ )/ ( x₂ - x₁)
For Micheal's puppy
Rate of change in weight when age is increased from 1 to 2 months = (17.2-8.6)/(2-1)=8.6 pounds per month
Rate of change in weight when age is increased from 2 to 3 months = (25.8-17.2)/(3-2)=8.6 pounds per month
∴ Rate of increase in weight of Micheal's puppy with age is 8.6 pounds per month
For Brittney's puppy
From graph it can be seen than
At age = 1 month , weight = 155 ounces = 9.6875 pounds
At age = 2 month , weight = 310 ounces = 19.375 pounds
At age = 3 month , weight = 465 ounces = 29.0625 pounds
Rate of change in weight when age is increased from 1 to 2 months = (19.375-9.6875)/(2-1)= 9.6875 pounds per month
Rate of change in weight when age is increased from 2 to 3 months = (29.0625-19.375)/(3-2)=9.6875 pounds per month
∴ Rate of increase in weight of Brittney's puppy with age is 9.6875 pounds per month
Thus rate of increase of weight is more for Brittney's puppy.
Therefore, Brittney's puppy gains more quickly weight.
